Out of Range

If this optional function is programmed into your radio,
it will indicate when you have left your radio coverage
area. The display will alternate between
model III
OUT OF RANGE
SOUTH DIVISION
and the current mode and/or the out of range tone will
sound.

Secure Operation

Note: This section applies only if secure operation is
programmed into your radio. This section lists fea-
tures where differences occur when operating in
secure. For other feature operation see General
Operation above.
Outgoing Calls: When the selected mode is not pre-
programmed as either secure-only or clear-only,
secure transmit is turned on/off by pressing the
secure button (4), except for trunking telephone inter-
connect and private call which are always controlled
by the button. A beep immediately after the PTT is
pressed indicates a clear (non-secure) transmission.
Note: If the secure button is pressed during a trans-
mission, the transmission is aborted, and an alert tone
will sound until the PTT is released. The operation
change will be effective with the next PTT press.
Incoming Calls: When a secure call is received the
orange LED (conventional only) and the secure icon
model II
Conventional Functions: In monitor, only calls from
OUT OF RANGE radios with the same encryption key will be heard.
Calls with a different key will be heard as noise.
Trunking Functions: When secure transmit is control-
led by the secure button (4), during a talk group or
private call you can only change from clear to secure
operation. During a telephone interconnect or fail-
soft call you can change from clear to secure opera-
tion, or from secure to clear. During an emergency
call NO change is possible.

Secure Keyload and Erase

An encryption key must be loaded from a Key Variable
Loader (KVL) that corresponds to the encryption type
of the radio.
Disconnect the microphone cable from the control-
head and attach the keyloader cable. The display
shows "KEYLOADING", and normal transmit and
will flash.
