Switching stealth mode on and off

Stealth mode allows you to quickly deactivate / reactivate the display and audio playback. The device will switch off completely after 10 minutes in stealth mode to conserve battery power.

 

In stealth mode power is not saved significantly, even when the display is deactivated. Thus, stealth mode will not prevent the batteries from running empty.

Switching to stealth mode:

Press the Stealth/Touch key (>1s).

The screen display and audio playback switch off. The status display LED flashes briefly every 3 seconds.

Switching off stealth mode and revert to measurement operation:

Press the Stealth/Touch key.
