5.20 P25 CONVENTIONAL FALLBACK

When P25 Conventional Fallback is enabled, a P25 trunking site responds to failures by allowing
one or more channels to operate as conventional repeaters. Terminals which are properly
configured can then communicate using the conventional P25 channel(s).
The radio provides an audible and visual indication when operating in P25 Conventional Fallback.

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 if 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.
• Channel/Group Knob Enabled – Specify if the Channel/Group Knob is enabled or disabled for
Stealth Mode.
