private operation and the correct cryptographic key
must be loaded into the radio.

Transmitting an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in private mode by pressing the

M key, then follow the selection mode rules.
On a System radio, the

4 key can be used to

toggle the private mode on/off. When private

mode is enabled, the icon will be on.

If the last state of the radio was private mode,
the private mode will be enabled on power up.
Also the private mode will be enabled if forced
operation has been programmed in the radio.

If a group or channel is not programmed for
private mode operation, "PVT DIS" will be
displayed if attempt is made to enable private
transmit mode. It is not possible to operate on
this group/channel in private mode.

If the radio does not have the correct encryption
key loaded, "NO KEY#" will be displayed and the
call will not be transmitted.

3. Continue with standard transmission procedures.

A private mode access tone will be heard when
the PTT button is pressed.
