NGT Transceiver System Technical Service Manual 105
Power off
If the transceiver is on when the key is pressed, IC3 pin 15 goes high. This causes
data to be sent via the handset bus to the RF unit.
Power is switched off when the microprocessor is instructed from the Application
Processor Handset I/F 3 V PCB (2011)/Application Processor Handset & Data I/F PCB
(2012) to drive V5, resetting relay K1.
The PWR ON line goes high, de-energising the power relay coil K200 and thus
switching off the transceiver.
