Voice Mail - Indicates message waiting signal if you subscribed to Voice Mail message service and requested Visual Message Indication from your local telephone company. (see page 12). B FCC REGULATIONS FCC Part 15 Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The equipment has been tested and found to comply with part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and , if not installed and used in accordance with the instructions,may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Correct the equipment into an outlet or on a ciucuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC Part 68 The FCC requires that you connect your cordless telephone to the nationwide telephone network through a modular telephone jack (USOC RJ11C or RJ11W). Your telephone company may discontinue your service if your equipment causes harm to the telephone network. They will notify you in advance of disconnection, if possible. During notification, you will be informed of your right to file a complaint with the FCC. If it is determine…

Recharging the Battery Pack The nickel metal hydride(Ni-MH) BATTERY PACK in the HANDSET can be recharged many times using the built-in charger in the BASE UNIT. When the BATT LOW symbol appears on the LCD screen , a "beep" sound will be heard every 10 seconds. This indicates that the BATTERY PACK needs to be recharged. Charge the BATTERY PACK at least once every 90 days of non-use to avoid battery failure. When the BATTERY PACK can no longer be charged, replacement of the BATTERY PACK will be necessary. The BATTERY PACK used in your telephone may develop a condition known as "MEMORY". Once subjected to a regular short discharging routine, the BATTERY PACK assumes the discharging pattern it was subjected to. This causes rapid discharging thereby shortening the BATTERY PACK charge span. If you believe your BATTERY PACK has developed a "MEMORY "condition, do not charge the HANDSET until the BATT LOW symbol appears on the LCD Screen. When the BATT LOW symbol appears on the LCD Screen, charge the HANDSET fully for 12 hours. . Recharging the Battery Pack IMPORTANT In order to get maximum life from the HANDSET BATTERY PACK, be sure to charge the HANDSET for 12 hours before initial use. 26 Ni-MH 2 Contents Saving in the Phone Book.............................................................................15 Preferred Calls............................................................................................... 15 Blocked Calls................................................................................................15 Editing the Number in the Phone Book ......................................................... 16 Placing Calls from the Phone Book................................................................17 Deleting All Records in the Phone Book.........................................................18 Selective Deleting in the Phone Book.............................................................18 Function Operation.................................................................................................19 A.

6210C CIRCUIT DESCRIPTION 1 Base a. RF Transmitter Section – RF Board The compressed audio signal (RF module pin 10) is modulated through the varactor diode D3. These components, i.e. D3, C42, L2, Q5 and the external components of Q7 compose the voltage controlled oscillator circuit for the transmitter part. This circuit generates the TX VCO frequency. A portion of this signal is fed back to the PLL IC1 (8825B)’s pin1 (FIN1) for phase comparison. Once the phase of oscillation stabilized, the PLL circuit generates the error voltage necessary for the VCO to oscillate at the desired transmitter’s RF frequency. The RF amplifier Q5 boosts the signal for transmission. This amplified RF signal is trimmed to the desired frequency band by FL2 (BPF903) so as not to interfere with the receiver circuit. The transmitter RF signal is then propagated through the antenna. b. RF Receiver Section – RF Board The Base Unit antenna receives RF signal. The Band Pass Filter FL1 (BPF927) trims the signal to the desirable frequency band. Transistor Q8 is a low noise amplifier that boosts the RF signal to a specific level for mixing. PLL IC1 (8825B) is used as a Universal Phase Lock Loop circuit. The frequency from the Voltage Controlled Oscillator (VCO) D1, L1 and Q4, is fed back to the PLL IC1 through pin 16 (FIN2) for phase comparison. During channel scanning or turning the unit on, once the phase of oscillation stabilized (locked), the PLL circuit generates the first local oscillator frequency for down-converting the received RF signal into the first IF frequency 10.7Mhz. This process is accomplished through the IF mixer circuit Q3. Q1 is used for matching the impedance of the mixer circuit with the succeeding circuits. The resulting IF signal is kept constant by the IF Filter FL3 to 10.7MHz which is then mixed with the second local oscillator frequency 11.150MHz (derived from X1 & C47) to produced a much lower IF frequency. This lower IF frequency if further filtered by IF Filter FL4 to produce a more stable signal of 450KHz. Quadrature signal detection is accomplished internally by the Narrow-band Detector IC2 (KA3361) with the IF coil L7. The recovered audio frequency can be taken from IC2 audio output pin9. c. Transmitter Audio Section – Main Board The Audio Frequency signal from the telephone line that is through R3,C5, Q1, IC1, R88, C10, etc is compressed through the compressor part of IC3 to minimize the transmission noise. The degree of compression depends on the external RC combinations. AGC is also utilized by IC4 to avoid shock noise caused by abrupt change of audio levels. The compressed audio is filtered and amplified for better acoustical performance. d. Receiver Audio Section – Main Board The compressed Audio Frequency signal from the RF module (pin4) is passed through passive RC filters for acoustic compliance. The filtered audio is then fed to the Compander IC4 (pin16 and pin17) for expansion thus retrieving the original Audio signal with noise filtered out. Through C21,R24,Q4,Q3 is used as buffer circuit. Bridge rectifier D1-D4 isolates the high-voltage telephone line to the rest of the circuit. 2 Handset a. RF Transmitter Section – RF Board Refer to portion 1.b for this section. All circuit performance is the same except that Band Pass Filter BPF903 is changed to BPF927 for the handset transmission. b. RF Receiver Section – RF Board Refer to portion 1.b for this section. All circuit performance is the same except that Band Pass Filter BPF927 is changed to BPF903 for the handset transmission. c. Transmitter Audio Section – Main Board Audio Frequency signal from the handset or from the headset microphone is compressed throug…
