When your radio is in the Covert Mode, you cannot enter the following menu items of the Setup menu.

• Set Volume

• Tones

• Backlight (in Display menu item)

When the Covert Mode is turned on:

• All tones are set to Off (corresponding to All Tones menu entry).

• The private speaker is set to Off.

• The dimmer state is set to covert (this state is not selectable using the B

ACKLIGHT

 key.)

• The wallpaper is disabled.

• The screen saver is disabled.

• The Covert Mode color palette is activated.

The radio powers up in the mode set before turning off. Thus if the Covert Mode was set before turning
off, the radio turns on in the Covert Mode .

When the Covert Mode is turned off, all the changed settings are reverted to the previous state.

When using the Covert Mode, a low audio accessory should be connected to the radio. The correct low
audio accessory is the GCAI Handset, or the older style handset connected through the junction box.
