■ Stun function

The dispatcher can send a 2/5-tone signal that will stun, kill
or revive your transceiver.
When the Stun ID is received, a beep sounds*, and the trans-
ceiver becomes unusable. Receiving a Revive command or
entering password* (p. 8) is necessary to operate the trans-
ceiver again in this case.
When the Kill ID is received, a beep sounds*, and the trans-
ceiver becomes unusable (the transceiver switches to the
cloning required condition). Cloning the transceiver is neces-
sary to operate the transceiver again in this case.
* Depending on the preprogramming. Ask your dealer for de-
tails.
See the operating guide for details of the Stun function
with the MDC and Digital system operations. Ask your
dealer for details.
