word is re-entered.
When the transceiver is in the lock mode, calls cannot be received or
transmitted. In addition, all controls except the on-off/volume control are
disabled. The transceiver then remains unlocked until it is locked again
by repeating this sequence.
Since the password is not preprogrammed, a different password can
be entered each time this feature is used. If the password is forgotten, the
transceiver must be returned to your system operator for reprogramming
to make it operational again.
