• USE ONLY WITH Panasonic AC ADAPTOR PQLV16CEZ.
• The AC adaptor must remain connected at all times.
(It is normal for the adaptor to feel warm during use.)
• When more than one unit is used, the units may interfere with each other. To prevent or reduce interference, please leave
ample space between the base units.

16.2. Power Supply Circuit
The power supply to the CPU (Digital, Analog) and RF IC from AC Adaptor (+12V) is shown in the diagram below.
The base unit power supply is DC12V. The handset´s power is supplied from 3.6V battery (Nickel-Cadmium battery) which is
installed in the handset.
Power supply for transmitter is turned on by a press of "Talk" key on the handset. During the stand-by mode, the unit stops
transmitting but receive thhe signal.
Also during on-hook condition (the handset is placed on the base unit), backup power for memory of the last dialed number is
supplied through the battery (3.6V nickel-cadmium in the handset). The memory of this unit is not backed up by the curreent
from the telephone line.
The base unit DC power supply is regulated by Q18, the CPU power is regulated by Q19. The Q8, detects AC Adaptor
powerfailure and maintains the unit cecutiry cord;

16.3. Reset Circuit (Base Unit)
After power supply from AC adaptor, the VREG is input for making reset signal. Refer to the below waveform.

KX-TC1205RUB / KX-TC1205R UW / KX-TC1205R US / KX-TC1205RUF

16.4. Charge Circuit
Circuit Operation:
When charging the handset on the base unit, the charge current is as follows;
DC (JK2) → L8 → D6 → L7 → CHG+(Base) → [CHG+(Handset) → L4 → Q9 → BATT(1)....Battery....BATT(2) → L5 →
CHG-(Handset)] → CHG+(Base) → L5,
In this way, the CPU on both unit detects the fact that the battery is charged.
The charge current is controlled by switching Q701 of Handset. The battery is charged in normal mode for 10 hours and then
in trickle mode.

16.5. Telephone Line Interface
Function:
• Bell signal detection
• ON/OFF hook and pulse dial circuit
• Side tone circuit
Bell signal detection and OFF HOOK circuit:
In the idle mode, Q103 is open to cut the DC loop current and decrease the ring load. When ring voltage appears at the Tip (T)
and Ring (R) leads (when the telephone rings), the AC ring volltage is transferred as follows.
JK1 (3): T → L6 → R144 → IC3D (12,13 → 14) → C97 → R148 → Q20 → IC2 (24) [BELL]
JK1 (2): R → L4 → R120 → R152 →↑
When the CPU (DSP) detects a ring signal and press the TALK Key on the handset. Q6 turns on and then RY1 turns on, thus
providing an off-hook condition (active DC current flow through the circuit) and the following singal flow is for the loop current.
T → R160 → L4 → RY1 → R107 → T7 → R116 → D5 → L6 → R161 → R [OFF HOOK]
ON HOOK Circuit:
Q6 is open, RY1 disconnected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an on-hook
condition.
Pulse Dial Circuit:
DSP (Relay) turns RY1 ON/OFF to make the pulse dialing via Q6.
Make/Break ratio when dialing with the Handset: 40%:60%
Side Tone Circuit:
Basically this circuit prevents the TX signal from feeding back to RX signal.
As for this unit, TX signal feed back from Q11 is canceled by the cancellor circuit of AGC.

16.6. Transmitter/Receiver
Base Unit and Handset are mainly consists of RF(Radio Frequency) IC and CPU.
Base Unit and Handset transmit/receive voice signal and data signal through the antenna on carrier frequency.
Signal Pass :
*Refer to CDL TX/RX in Signal Route (P.44).

16.6.1. Base to Handset
Circuit Operation:
The voice signal input from the TEL LINE interface goes to RF IC as shown in
BLOCK DIAGRAM (BASE UNIT) (P.36).
In the talk mode (off-hook) condition, the telephone line voice signal passes through D2, D3, D4, D5, RY1 (Relay), R107 and
T7.
The other party´s voice signal is coupled with T7 and amplified by Q11 and led to IC3-B (OP Amplifier device).
And the signal goes through the compressor of RF IC, it is output to transmitter circuit.
The signal of the data sent to the handset is applied in the anode of the variable capacitor diode (VARICAP : DV1).
The capacitor of VARICAP is changing in accordance with the voice signal from telephone line interface or TX DATA signal from
CPU.
Therefore, the carrier frequency which is generated by TXVCO will be changing, and Frequency modulated RF signal is
generated and amplified by RF AMP(Q3, Q4, T5).
It pass through the Duplexer DPX1 and radiated from Antenna.
The signal is transmitted from the base unit and received by the handset antenna and amplified by RF amplifier (Q1) through
DPX1 as shown in BLOCK DIAGRAM (HANDSET) (P.37). And then it is converted to 10.7 MHz and 450 KHz Intermediate
frequency by RF IC and related components.
The demodulated audio signal is output from RF IC (DET OUT) and passed through "Expander" process to reduce noise, then
voice signal amplified by "Receiver amplifier" is output to receiver (REC1).
The receiver loudness is adjustable using "LOUD" key on the handset. Q2 and Q3 control the volume. When CPU (VOL1)
becomes low, the volume becomes “MID”, while CPU (VOL 1,2) becomes low, the volume becomes "HIGH".
TX data (to Handset)
CPU (VTX) becomes low to turn on the transmission power transistor Q2, and CPU (TX-data) sends data signal. It is FMmodulated by TXVCO and driven by RF AMP, then transmitted to the handset.

42

KX-TC1205RUB / KX-TC1205R UW / KX-TC1205R US / KX-TC1205RUF

16.6.2. Handset to Base
Circuit Operation:
The voice signal from the handset user is picked up by the microphone (MC1), voice signal passes through "Compressor"
process to reduce noise as shown in BLOCK DIAGRAM (HANDSET) (P.37). And the voice is FM-modulated by VARICAP
(DV1).
The carrier frequency is generated by TX VCO. The transmitter power transistor Q4 is turned on/off by CPU (VTX).
The carrier signal is amplified by RF AMP and sent to the handset duplexer and antenna.
The signal of 49MHz band (49.670~49.99MHz) which is input from ANT is filtered at DPX1 as shown in
BLOCK DIAGRAM (BASE UNIT) (P.36), then it is input to RF IC.
The signal input to RF IC is converted through Mixer inside of RF IC, RF filter (CF1, CF2) and Expander.
The signal is transmitted from the handset and received by the base unit antenna and amplified by RF amplifier Q1, then it is
converted to10.7 MHz and 450 KHz Intermediate by RF IC. The demodulated audio signal is output from RF IC (DET OUT) and
passed through "Expander" process to reduce noise, then voice signal is led to LINE AMP.
The signal is passed through TELEPHONE INTERFACE and Tel-line.
RX data (from Handset):
The data signal from handset (ex: Talk, ACK, COM) is also included in 49 MHz band same as the voice data. After second if
filter, the data signal is made square shape by data limiting AMP of the RF IC. RX data is output to CPU (RX Data).

16.6.3. RF signal operation/control and PLL operation (RF UNIT)
Base unit radio frequency signal received by antenna passes through duplexer (DPX1). RF signal is amplified by RF AMP.
RF signal received from RF IC is mixed with RX local frequency at Mixer to generate 10.7 MHz wide band IF. The reference
frequency is generated by X1 11.15 MHz crystal.
VC1 is the reference frequency for adjustment. The 10.7 MHz is mixed with reference and 450KHz narrow band IF is generated.
The demodulation audio signal is adjusted to the maximum at T1.
RF IC is controlled by CPU (RF_STB, DATA, CLK). The RX local frequency is generated by RXVCO.

17.2. Battery Low / Power Down Detector
Circuit Operation:
“Battery Low” and “Power Down” are detected by RF IC which check the voltage from battery. Shortly, every detected blocks
are inside of RF IC. The detected voltage is as follows;
• Battery Low
Battery voltage : V(Batt) < 3.57V
The CPU detects this level and “Recharge battery” LED starts flashing.
• Power Down
Battery voltage : V(Batt) < 3.3V
The output of RF IC (P-DOWN) becomes low level, then CPU stops working to keep the data (CH number, ID Code, etc.)

25 FOR SCHEMATIC DIAGRAM
25.1. Base Unit (SCHEMATIC DIAGRAM (Base Unit))
1. DC voltage measurements are taken with an oscilloscope or a tester with a ground.
2. The schematic diagrams and circuit board may be modified at any time with the development of new technology.
Important Safety Notice:
Components identified by
mark have special characteristics important for safety. When replacing
any of these components, use only the manufacturer´s specified parts.

25.2. Handset (SCHEMATIC DIAGRAM (Handset))
1. DC voltage measurements are taken with an oscilloscope or a tester with a ground.
2. The schematic diagrams and circuit board may be modified at any time with the development of new technology.
