5.21 STEALTH MODE
For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the
radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise
unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display
lights, indicator lights, audible alert, and side tones. When Stealth Mode is on, the radio continues to scan
the programmed list of Talk Groups and the user can key-up on the selected Talk Group. A button or the
two-position switch can be programmed via RPM2 to enable/disable Stealth Mode.
The following Stealth Mode options are configurable via RPM2:
Persistence Enabled Specify whether or not Stealth Mode persists after the radio is powered down.
LCD Enabled Specify if the LCD is enabled or disabled for Stealth Mode.
LED Enabled Specify if the LED is enabled or disabled for Stealth Mode.
Backlight Enabled Specify if the Backlight is enabled or disabled for Stealth Mode.
Side/Alert Tones Enabled Specify if side tones and alert tones are enabled or disabled for Stealth
Mode.
Voice Annunciation Enabled Specify if Voice Annunciation is enabled or disabled for Stealth Mode.
Channel/Group Knob Enabled Specify if the Channel/Group Knob is enabled or disabled for Stealth
Mode.
