TXCVR Lock
This section enables the network operator to send a special key (programmed into
a transceiver during programming) by Selcall to disable that transceiver. The
transceiver remains locked until an unlock code is entered.
This function can be used if the transceiver has been stolen and it is being used
illegally.
The lock call will be made on the channel selected before entering this function.
The channel number is shown on the TXCVR display.
Before proceeding if the channel presently selected is not a Selcall channel the
following is displayed
