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.
