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 and CIB to the RF unit.
The CIB data is decoded and the microprocessor IC12 pin 17 goes high. This causes V6
to conduct and energise the coil K1-OFF, thus opening the contacts K1/C and K1/D.
The PWR ON line goes high, de-energising the power relay coil K200 and thus
switching off the transceiver.
