KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.1.3. Signal Flowchart in the Radio Parts Reception A voice signal from TEL line is encoded to digital data "TXDATA" by BBIC (IC501) in a base unit. Then TXDATA goes to RF PART and it's modulated to 1.9 GHz. The RF signal is amplified and fed to a selected antenna.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4. Circuit Operation (Base Unit) General Description: (BBIC, EERROM) is a digital speech/signal processing system that implements all the functions of speech compression and memory management required in a digital telephone. The BBIC system is fully controlled by a host processor. The host processor provides activation and control of all that functions as follows.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4.3. Power Supply Circuit/Reset Circuit The power supply voltage from AC adaptor is converted to VBAT (3.0V) in IC302. And +3.0V for peripherals and analog part is insulated from VBAT by Doubler of BBIC. Circuit Operation:...
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 188.8.131.52. Charge Circuit The voltage from the AC adaptor is supplied to the charge circuits.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4.4. Telephone Line Interface Telephone Line Interface Circuit: 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, Q141 is open to cut the DC loop current and decrease the ring load.

KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4.5. Parallel Connection Detect Circuit/Auto Disconnect Circuit Function: In order to disable call waiting and stutter tone functions when using telephones connected in parallel, it is necessary to have a circuit that judges whether a telephone connected in parallel is in use or not. This circuit determines whether the telephone connected in parallel is on hook or off hook by detecting changes in the T/R voltage.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.4.6. Calling Line Identification (Caller ID) Function: Caller ID The caller ID is a chargeable ID which the user of a telephone circuit obtains by entering a contract with the telephone company to utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has been entered for the circuit being used.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N Call Waiting Caller ID Calling Identity Delivery on Call Waiting (CIDCW) is a CLASS service that allows a customer, while off-hook on an existing call, to receive information about a calling party on a waited call. The transmission of the calling information takes place almost immediately after the customer is alerted to the new call so he/she can use this information to decide whether to take the new call.

KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.7.3. Charge Circuit Circuit Operation: When charging the handset on the Base Unit, the charge current is as follows; DC+(6.5 V) → F301 → R371 → R372 →CHARGE+(Base) → CHARGE+(Handset) → Q4 → D7→ F1 → BATTERY+... Battery... BATTERY- → R45 → GND → CHARGE-(Handset)→ CHARGE-(Base) → GND → DC-(GND) In this way, the BBIC on Handset detects the fact that the battery is charged.
KX-TG4011N/KX-TG4012N/KX-TG4013N/KX-TGA402N 4.8. Circuit Operation (Charger Unit) Charge control is executed at handset side so that the operation when using charger is also controlled by handset. Refer to Circuit Operation (Handset) (P.20) The route for this is as follows: DC+pin of J1(+) → F1 → R1 → CHARGE+pad → Handset → CHARGE-pad → DC-pin of J1(-).
