OpenSky P800 User Manual page 56

If you've been conducting covert operations and are ready
to re-enable your radio's lights, display screen and side
tones for ordinary use, a simple flip of the Toggle Switch
will return the P800 to full function. A "covert" radio looks
like a "powered-off" radio. But re-enabling your functions
has immediate results. You won't have to wait through the
startup sequence and your radio will not be re-provisioned
when you flip the toggle to re-enable your lights and tones.
How to Enable Lights and Tones
•
Push the Toggle Switch to the left until it snaps into
position.
•
The Display Panel will brighten, the Indicator light
will turn on, and the Side Tones (the audible beeps
you hear when you use the menu buttons) will be re-
enabled.
•
To test your side tones, press a Menu button and
listen for the confirming tone.
