Unplug this telephone from the wall outlet and consult a qualified service representative in any of the following situations: A. When the power supply cord is frayed or damaged. B. If liquid has been spilled into the telephone. C. If the telephone has been exposed to rain or water. D. If the telephone does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions. Improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the telephone to normal operation. 3 E. If the telephone has been dropped or the case has been damaged. F. If the telephone exhibits a distinct change in performance. 13. Do not use the telephone to report a gas leak in the vicinity of the leak. 14. Never install telephone wiring during a lightning storm. 15. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. 16. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. 17. Use caution when installing or modifying telephone lines. SAVE THESE INSTRUCTIONS Battery Safety CAUTION: Danger of explosion if the BATTERY PACK is incorrectly replaced. Replace only with the same or equivalent type. To reduce the risk of fire or personal injury, read and follow these instructions: 1. Use only the following type and size of BATTERY PACK: Cordless Telephone BATTERY PACK 3.6V, 600mAh U.S. Electronics Inc. Ni-MH BATTERY PACK: Model B655 (See page 16 for ordering information.) 2. Do not dispose of the BATTERY PACK in a fire. It may explode. Check with local codes for possible special disposal instructions. 3. Do not open or mutilate the BATTERY PACK. Released electrolyte is corrosive and may cause damage to the eyes or skin. Electrolyte may be toxic if swallowed. 4. Exercise care in handling the BATTERY PACK to prevent shorting the BATTERY PACK …

CIDMATE International Technology Inc. 3F-B, No. 58, Sec. 1, Minsheng E. Rd., Taipei, Taiwan 104, R.O.C. Tel: 886-2- 2521-8658 Fax: 886-2-2561-6624 Email: [email protected] OPERATION DESCRIPTION „ HANDSET 1. RF/Audio Section The radio link Handset and Base is full duplex at 2400/2483.5 MHz with the 40 channels. FM modulation is used for the link. The 1 st IF frequency is 10.7MHz and the 2 nd IF frequency is 450KHz. The operating frequency for the cordless phone is selected from one of the following channels and controlled by the synthesizer U2 that is programmed by the MCU. This section is common to both handset and base as the same ICs are used LMX1602(U2), KA3361(U1) is made up of dual serial input PLL frequency synthesizer with 1000MHz prescaler. KA3361 is a narrow-band IF detector IC. 1.1 Receiver The receiver section is made of double conversion with 10.7MHz as the first and second IF. Rx signal from the duplexer circuit is amplified by a Low Noise RF transistor and passed to a Mixer (Q2), and it is converted to 10.7MHz IF and it is then double converted to 450KHz IF in the internet mixer of U1. Voice/data signal is demodulated and output from pin9 of U1. The demodulated signal is then divided into two paths, a path is fed into the data amplifier Q1, Q10. The other path will go through a de-emphasized amplifier and an expander in IC1. Recovered signal can be muted by the pin 13 of IC1,the volume level of the signal can be controlled by the push switch SW1. 1.2 Transmitter Audio signal (from Microphone for headset/Tip & Ring for base) is first fed into the amplifier and compressor inside IC1(IC2 for Base). The signal will pass through a limiter. The AGC and the limiter have the property to limit the maximum signal that feed into the transmitter so that the RF deviation is limited. The transmitter section mainly divided into two parts. They are the voice/data modulator and the Tx power amplifier. The voltage-controlled oscillator VCO operated at the Tx frequency controlled by the synthesizer is modulated by the audio and data signals. Modulated signal is amplified by the RF amplified and sending the signal to the duplexer for radiation by the antenna. 1.3 Band-Pass Filter(BPF) The function of the Two Band-Pass Filter(BPF) is to individual fed the transmitting and receiving signals to a common antenna while providing isolation and rejection of CIDMATE International Technology Inc. 3F-B, No. 58, Sec. 1, Minsheng E. Rd., Taipei, Taiwan 104, R.O.C. Tel: 886-2- 2521-8658 Fax: 886-2-2561-6624 Email: [email protected] interference and other spurious signals. 1.4 Alerter The alerting signals include the following: Ringing, Paging, Key beep and Low battery warning tone. These tones are generated by the MCU to the alerter through the driving circuit formed Q5,Q6 and the associated components. 1.5 Headset microphone The condenser microphone is in the headset and it biased by the resistor R6. The signal is applied to the amplifier inside IC1 2. MCU 2.1 Battery Detect The voltage detector is composed of U3 that is used to detect battery low condition. The detecting accuracy of the voltage detector is +/- 0.2V. The detect pin BAT-LOW is connected to the pin 70 of MCU. 2.2 Carrier Detection This 40 channels cordless has the features of auto-scanning. This is done by the detection of the RSSI at pin 72 of MCU of handset. During PHONE on or CHANNEL changing, the MCU will select the clearest channel for the RF communication. „ BASE 3. RF/Audio sections The operation of the RF/Audio section is similar to that of the handset. 4. Telephone Network 4.1 Telephone interface Fuse FUSEx is for over-voltage protection. Relay RL1 controls the on/off hook state and pulse dialing. The Tip& Ring are isolated from the base circuit by the transformer T1, relay RL1.

Tel: 886-2- 2521-8658 Fax: 886-2-2561-6624 Email: [email protected] 4.2 Ring Detect When ring signal is present on the Tip Ring, and envelope waveform of the ring pattern will transfer to pin 20 of MCU by the LM324 pin 14. The MCU will read this waveform and determine whether it will send ringer command. 4.3 Sidtone Cancellation Network The sidetone cancellation is a hybrid circuit of the Tx and Rx paths of the telephone circuit formed by the Q12. 5. MCU 5.1 Charging Network Base charging circuit provides a DC current for handset battery. Resistor R129 controls the current flow. 5.2 Carrier Detection This is similar to the handset counterpart. 6. Digital Answer System Digital Answer System is consist of a DSP chip (MX93132, U7) and flash memory chip (MX29F400T, U4), audio output amplifier for audio (LM386, U10) 6.1 MX93132 provides speech processing/ management modules, including speech compression/ decompression silence management, telephone line signal processing RAM Management line echo cancellation and acoustical echo cancellation, etc. 6.2 MX29F400T: Memory Chip - resources of DAS. 6.3 LM386: Amplifier for audio output.
