MEAD BOND - SIZE: 8.500” X 5.500” - SCALE: 1-1 - FOLDING: ALBUM FOLD - BINDING: SADDLE-STITCH 214601 X1 - IMAGE 1 CONSOLE DESCRIPTION Novi’s 5-channel Wireless Intercom Consoles provide a wireless audio communication link between up to five Console stations and one or two remote Wireless Doorbell Intercom units. The intercom uses digital signals to control the stations called and provide a unique “security code” that prevents other nearby Novi 5-channel intercoms from accessing the system. Either of two radio frequencies can be selected for the intercoms to further eliminate the chance of interference from adjacent systems. The Console features five station number pushbuttons for selecting the party to call. The ALL CALL button can be used to call all five stations. Pressing the TALK button calls the selected station(s), then controls the direction of the conversation. Each intercom user presses their TALK button to activate the microphone during the conversation. The Doorbell works with Console stations 4 or 5. Pressing the Doorbell’s TALK button sounds a “ding-dong” (station 5), or “dong” (station 4) at the Console, then the conversation begins by pressing the units’ talk buttons. For privacy, a MUTE switch on each Console can be set to prevent Wireless Doorbell tones and ALL CALL messages from sounding through that Console’s speaker. The Console can be placed on a table or shelf, or mounted to a wall with the screws provided. The small, antenna adjusts for Console table or wall mounting. Power for the Console is provided by a small plug-in transformer. The Doorbell attaches to a wall with the mounting plate provided. Two 9-volt alkaline batteries power the Doorbell intercom.

To: John K Subject: RE: Linear Corp. Part 95B radio FCC ID: EF4RFI00001 John: we have completed the review of your application, and invite your response to the following comments: 1) Form 731 emission designator: please define the necessary bandwidth to accompany the emission designator F3E. A maximum deviation of 12.5 kHz is permitted, but the necessary bandwidth should be calculated from the formulas in 2.202(b) - or, if there is no appropriate formula - on the 99% bandwidth. The value should be justified by measurement or calculation. 2) Tune-up procedure per 2.1033(c)(9): cannot find, please indicate where to look, or provide. 3) RF power per 2.1046: the measurement method is not clear. Please note that for non-detachable antennas the output power should be determined by the substitution method of ANSI/TIS/EIA-603, which is also a good guide for other mobile radio measurements. 4) Modulation characteristics per 2.1047: please provide plots of frequency characteristics and modulating limiting characteristics per the attached samples from certified devices. A table showing modulation index would be desirable. 5) Occupied bandwidth per 2.1049: How was the occupied bandwidth measured in the test report? 6) Spurious emissions at antenna terminals per 2.1051: Please provide a plot showing compliance with the emission mask, per the attached sample. 7) Frequency stability per 2.1055: Refers to a temperature limitation in the user manual, which I cannot find; please indicate where it is found. The required test range for this device is -30 to +50C, and no exceptions are generally allowed. Devices may cease operation before the extremes are met, and that is acceptable. Please comment.

LABEL FACSIMILE FCC ID: EF4 RFI00001 Product ID: RFI00001 Model:FRS Base Station Radio Transceiver Linear Corporation This device complies with FCC Rules Part 15 and Family Radio System (FRS) Part 95. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

1.0PRODUCT DESCRIPTION The RF Intercom Console (RI-C) is a five-channel intercom unit, which allows half- duplex conversation over either a 467.6875 MHz or a 467.5625 FM signal. Key features include: • 1024 random house codes (programmable) to reduce interference from units in other systems (transparent to the user). • 5 station codes (programmable). • 5 push-button switches to select the receiving station. • 5 Channel LED’s to indicate called/calling location. A fast flashing LED indicates that the corresponding station is in use. A slow flashing LED indicates that call is in progress and the unit is receiving a call. • A Press-to-Talk button. • An All Call button to select all units in the system. • A Call Lockout switch to inhibit All Call and DoorBell. • Power on LED. • Digital Calling to activate the unit only when the house and station codes match. • Tone squelch. • On/Off switch. • Internal speaker & microphone. • External antenna. • Speaker volume control. • AC wall mount transformer. 2.0HARDWARE/SOFTWARE SPECIFICATIONS 2.1MECHANICAL All electronics shall be contained in a plastic enclosure with the dimensions 7.5 x 5.5 x 1.4 inches. The body and button colors shall be gray. 2.2ELECTRICAL 2.2.1 DC CHARACTERISTICS Input Power:9VDC supplied by the AC Wall Mount Transformer Input Current:100 mA 2.2.2 AC CHARACTERISTICS System Frequency:467.6875 MHz or 467.5625 MHz Modulation Type:FM Receiver Sensitivity:-100 dBm minimum Transmitter Power Output:100 mW nominal 2.3REGULATORY AGENCIES The unit shall comply with FCC part 95 regulations. 2.4ENVIRONMENTAL Temperature:0 to +50°C (Indoor Applications) 2.5USER INTERFACE 2.5.1 SELECT CALL BUTTONS Five Select Call buttons allow selection of individual remote units. Pressing the button again will de-select the remote unit. The remote unit is also de-selected if: • The Press-to-Talk button is not pressed within 20 seconds of the call selection. • The Press-to-Talk button is not pressed within 20 seconds of the loss of incoming RF. • Correct incoming code is not detected within 20 seconds of the release of the Press- to-Talk button. 2.5.2 PRESS-TO-TALK BUTTON After selecting the remote unit using the Select Call buttons, the user may press the Press-to-Talk button to initiate RF data and voice transmission. At the press of the button, with the microphone disabled, the unit first sends out the house code, the Transmitting Station’s code, and the Receiving Station(s) code. Then the unit enables the microphone and allows the user to transmit voice over RF. When the button is released, the unit disables voice transmission and sends out an 83.3Hz tone to tell the receiving station to shut off its speaker. After a 0.25 second delay, the unit then goes into a receive mode and waits for a response. The Press-to-Talk button is also used to program the house address (refer to the programming section 3.0). 2.5.3 ALL CALL BUTTON An All Call button may be pressed to select all units with the same house address. When the Press-to-Talk button is pressed, all units will enable their speakers. If all stations have been selected, press of the All Call button will de- select all stations. The All Call button is also used to program the house address (refer to the programming section 3.0). 2.5.4 ALL CALL LOCKOUT SWITCH The All Call Lockout Switch is used to keep the speaker off during an All Call or when the doorbell is activated. 2.5.5 CHANNEL FREQUENCY SELECT SWITCH To reduce interference from non-system RF transmitters, the channel frequency may be switched between 467.6875 MHz and 467.5625 MHz, via a slide switch. 2.5.6 LED INDICATORS Five LED indicators are used to indicate called/calling locations. A blinking LED indicates that the corresponding location is in use. 2.5.7 POWER ON LED A green LED is used to indicate that the power is on. 2.5.8 VOLUME CONTROL POTENTIOMETER A potentiometer is used to control the speaker volume. 2.5.9 ON/OFF SWITCH The on/off switch is integrated with the volume control potentiometer. 2.5.10 POWER INPUT The power to the unit is supplied via a wall mount transformer. 2.6MICROCONTROLLER All programming and control functions are performed via a microcontroller on- board. 2.7RF TRANSMITTER The RF Transmitter Circuitry transmits FM data and audio over either a 467.6875 MHz or a 467.5625 MHz carrier signal. The Transmitter is disabled when its supply is shut off by the microcontroller. 2.8RF RECEIVER The RF Receiver Circuitry receives FM signals and converts them to audio and data that is usable by the microcontroller. 2.9MICROPHONE An internal microphone, which is enabled or disabled by the microcontroller, is used for audio input. 2.10 SPEAKER An internal speaker, which is enabled or disabled by the microcontroller, is used for audio output. 2.11 SQUELCH To reduce the noise that is generated on the speaker when the Press-to-Talk button is released on the transmitting unit, the transmitter sends out an 83.3Hz tone to the receiver before it shuts off RF. The receiver disables its speaker before RF goes away. If the tone is corrupted for some reason, a squelch signal that is generated by the RF Receiver is sent to the microcontroller. 2.12 CALLING STATION DATA FORMAT The transmitting station sends out a coded signal to select the appropriate receiver when the Press-to-Talk is initially pressed. The total word length is approximately 96ms. 3.0PROGRAMMING At the factory, a 10 bit, sequentially selected, house code will be programmed into the units. This code will be transparent to the customer. Also, the unit number will be “1”. Since each unit in a system may have a different house code, the house code must be re-programmed by the user. In order to do so, one unit must become the master unit and the rest of the units in the system will be slaves. The master unit must teach the house code to the units in the system. When the units are programmed, the factory code in the master will be programmed into the slaves. The programming mode shall …

(Switches away from the LEDs) 3. Power up unit under test while pressing the S3 (ALL CALL) and S5 (CH 1) buttons (factory test mode). • Note: The unit under test will come up in the transmit mode. 4. Verify that the current from the 9 VDC power supply is between 75 and 125 mA. 5. Adjust L12 until the voltage at TP2 is 3.5 volts DC (+/- 0.2 volts). 6. Adjust C76 until the frequency at E10 is 467.6875 MHz (+/- 0.00025MHz) on the frequency counter. 7. Place S4 (Channel Select) and S1 (Lockout) in the OFF position (Switchs toward the LEDs). 8. Place S1 (Lockout) in the ON position (Switch away from the LEDs) and verify that the frequency counter now reads 467.5625. 9. Place S4 (Channel Select) in the ON position (Switch away the LEDs) and S1 (Lockout) in the OFF position (Switch toward the LEDs). 10. Disconnect the frequency counter and connect the spectrum analyzer to E10 (Antenna connection). Set the spectrum analyzer to a center frequency of 467.6875 MHz and a span of 100 KHz. Place S1 (Lockout) in the ON position (Switch away from the LEDs). 11. Press S5 (CH1) and verify that the bandwidth of the signal on the spectrum analyzer is less than 12.5 KHz. 12. Place S1 (Lockout) in the OFF position (Switch toward the LEDs). The unit under test will change to the receive mode. 13. Verify that the current from the 9 VDC power supply is between 30 and 75 mA. 14. Adjust L15 until the voltage at TP4 is 3.5 volts DC (+/- 0.2 volts). 15. Remove the frequency counter from E10. Connect the signal generator to E10. 16. Set the signal generator to 467.6875 MHz at -67 dBm. • Note: Make sure that the RF output is turned ON. TEST PROCEDURE, RFI00001214600 X SHEET 4 OF 3 17. Adjust L18 until the voltage at TP9 is 2 volts DC(+/- 0.1 volt). 18. Turn the RF output of the signal generator OFF. 19. Turn R75 fully counter-clockwise. 20. Adjust the test fixture 10k potentiometer so that the hissing noise from the test fixture speaker can be heard. 21. Adjust R75 clockwise to the point where the hissing noise stops. 22. Turn ON the signal generator and set its output -87 dBm with 2KHz deviation of FM modulation at 400Hz. • Note: The 400Hz tone should be heard on the speaker. 23. Adjust R75 until the 400 Hz tone can no longer be heard. 24. Set R75 half way between its current position and the position it was in after step 21. The squelch will now be at the optimal setting. 25. Cycle power to the unit under test. 26. Press and release the S5, S6, S7, S8, and S9 (CH1 through CH5) buttons and verify that the corresponding LED (D7, D8, D9, D10, and D11) illuminates. 27. Remove power from the PCB. This concludes the test procedure.
