Covert Mode
This feature enables you to completely shut down all visible and audible alerts and notifications making
the radio unnoticeable even in a silent and dark environment.
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).
• Group audio is set to Spkr Cntrl (corresponding to Audio Toggle menu entry).
• The private speaker is set to Off (this setting causes all the calls are routed through the earpiece).
• Backlight is set to Disabled (corresponding to Backlight menu entry).
• The LED indicator is switched off.
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 .
