An audible tone will indicate the radio is on. 2 O N - O F F / VOLUME s w i t c h LOCKtab O P E R AT I O N 3 ENGLISH Battery Low When battery power is low, the BATT LOW indicator will blink. Auto Battery Save Your microTALK ® radio has a unique circuit designed to extend battery life. If there are no transmissions within 10 seconds, the unit will automatically switch to Battery Save mode and POWER SAVER will appear in the display. This will not affect the unit’s ability to receive incoming transmissions. Selecting a Channel 1.With the radio on, select any of the 14 channels by pushing the CHANNEL UP or CHANNEL DOWN button. (N O T E :B o t h radios must be tuned to the same channel to communicate.) Selecting a CTCSS Privacy Code CTCSS (Continous Tone Coded Squelch System) is an advanced tone coding system allowing you to select one of 38 privacy codes to reduce interference from other users on the channel. (N O T E :If you are using a privacy code, both radios must be tuned to the same channel and privacy code to communicate. Each channel will remember the last privacy code you selected.) To select a privacy code: 1.After selecting a channel, press and release the MODE button. Small numbers will flash next to the channel in the LCD. 2.Push the CHANNEL SELECT button up or down to select a privacy code. You can hold the button up or down for fast advance. 3.When your desired privacy code is displayed, press and release the MODE button, or do not push any buttons for 15 seconds. Calling Another Person To alert another person that you are calling: 1.Press and release the CALL button. The other person will hear a 2-second ringing tone. You cannot send or receive transmissions during the 2-second call tone.

Safety Information For FRS UNIT Your wireless handheld portable transceiver contains a low power transmitter. When the PTT button is pushed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. Important: To maintain compliance with the FCC s RF exposure guidelines hold the transmitter at least 2 inches (5 centimeters) from your face and speak in a normal voice, with the antenna pointed up and away. If you wear the handset on your body while using the headset accessory, use only the Cobra supplied belt clip for this product and ensure that the antenna is at least 1 inch (2.5 centimeters) from your body when transmitting. If the distance between the antenna and the body is LESS THAN 1.0”(2.5cm) DO NOT USE THIS DEVICE IN THE BODY WORN CONFIGURATION. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. Normal Position: Hold the transmitter approximately 2” from your face and speak in a normal voice, with the antenna pointed up and away.

ENGINEERING STATEMENT For Type Certification of Cobra Electronics Corporation Model No: FRS 235C FCC ID: BBOFRS235C I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Cobra Electronics Corporation to make type certification measurements on the FRS 235C transceiver. These tests made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for Type Certification are included in this report. The data verifies that the above mentioned transceiver meets FCC requirements and Type Certification is requested. ______________________________ Rowland S. Johnson Dated: December 17, 2001 A. INTRODUCTION The following data are submitted in connection with this request for type certification of the FRS 235C transceiver in accordance with Part 2, Subpart J of the FCC Rules. The FRS 235C is a portable, battery operated, UHF, frequency modulated transceiver intended for 12.5 kHz channel family radio service applications in the 462.5625-467.7125 MHz band. It operates from a nominal 6.0 Vdc battery supply. MFR rated output power is 0.4 watts ERP. B. GENERAL INFORMATION REQUIRED FOR TYPE CERTIFICATION (Paragraph 2.983 of the Rules) 1. Name of applicant: Cobra Electronics Corporation 2. Identification of equipment: FCC ID: BBOFRS235C a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as a separate exhibit. 3. Quantity production is planned. 4. Technical description: a. 11k0F3E emission b. Frequency range: 462.5625 - 467.7125 MHz. c. Operating power of transmitter is fixed at the factory at less than 0.5 W ERP. d. Maximum power permitted is 0.5 watts, and the FRS 235C fully complied with that power limitation. e. The dc voltage and dc currents at final amplifier: Collector voltage: 5.6 Vdc Collector current: 0.39 A f. Function of each active semiconductor device: See Appendix 1. g. Complete schematic diagram is submitted as a separate exhibit. h. A draft instruction manual is submitted as a separate exhibit. i. The transmitter tune-up procedure is submitted as a separate exhibit. 2 B. GENERAL INFORMATION (continued) j. A description of circuits for stabilizing frequency is included in Appendix 2. k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 3. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF Power Output (Paragraph 2.985(a) of the Rules) The FRS 235C has a permanently attached built-in antenna without provisions for a coaxial connector. RF power output was determined by substitution. TABLE 1 Operating Freq., MHz Power watts into a dipole antenna 462.5625 0.39 D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One integrated test system. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with a Audio Precision System One integrated test system. The curves show compliance with paragraphs 2.987(b). 3. Figure 3 is a graph of the post-limiter low pass filter which provides a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One integrated test system on the Boonton 8220 modulation meter audio output. 3 4. Occupied Bandwidth (Paragraphs 2.989(c) of the Rules) Figure 4 is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2416 Hz, the frequency of maximum response. Measured modulation under these conditions was 1.8 kHz. Emission designator: (2M + 2D) (2 x 3 kHz) + (2 x 2.5 kHz) = 11k0F3E 4 FIGURE 1 MODULATION FREQUENCY RESPONSE MODULATION FREQUENCY RESPONSE FCC ID: BBOFRS235C FIGURE 1 5 FIGURE 2 AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: BBOFRS235C FIGURE 2 6 FIGURE 3 AUDIO LOW PASS FILTER RESPONSE AUDIO LOW PASS FILTER RESPONSE FCC ID: BBOFRS235C FIGURE 3 7 FIGURE 4 OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency more than 50% up to and including 100% of the 25 authorized bandwidth, 12.5 kHz (6.25-12.5 kHz) On any frequency more than 100%, up to and including 250% of the 35 authorized bandwidth (12.5-31.25 kHz) On any frequency removed from the assigned frequency by more 43+10LogP = 39 than 250% of the authorized (P = 0.39) bandwidth (over 31.25 kHz) OCCUPIED BANDWIDTH FCC ID: BBOFRS235C FIGURE 4 8 D. MODULATION CHARACTERISTICS (Continued) The plots are within FCC limits. The horizontal scale frequency) is 10 kHz per division and the vertical scale amplitude) is a logarithmic presentation equal to 10 dB per division. E. SPURIOUS EMISSIONS AT THE ANTENNA TERMINALS (Paragraph 2.991 of the Rules) The FRS 235C has a permanently attached antenna. There is no connector for an external antenna. Therefore, no antenna terminal conducted measurements were made. F. MEASUREMENTS OF SPURIOUS RADIATION Measurements of radiated spurious emissions from the FRS 235C were made by substitution with a Tektronix 494P spectrum analyzer using Singer DM-105 for the measurements to 1 GHz, and EMCO 3115 horn to 4.8 GHz. The transmitter was located in an open field 3 meters from the test antenna. Supply voltage was a power supply with a terminal voltage under load of 6.0 Vdc. The transmitter and test antennae were arranged to maximize pickup. Both vertical and horizonta…
