7.16 CHECKING OR CHANGING THE SELECTED TALK GROUP
Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group within the
currently active profile is set as the “selected talk group.” For the radio user, the selected talk group is
typically the focus of most voice transmissions and receptions. There are two ways to change the selected
talk group:
First Method:

display. The currently selected talk group appears in the top line of the display.

determined by the OpenSky network administrator.
Second Method:
From the dwell display, use the talk group selection knob or to scroll through the available list of
talk groups in the active profile.
7.17 ADJUSTING DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS
The radio uses a light sensor on the front panel to automatically adjust display brightness and button
backlight brightness to ambient light conditions. The display and backlights automatically brighten at
higher external light levels and automatically dim at lower external light levels. However, the “Bright
Menu” gives the user some manual brightness control as follows:
1. Using , scroll through the menu until “Bright Menu” appears.
2. Use to increase or decrease brightness. Display and button backlight brightness will
immediately dim or brighten.
7.18 STEALTH MODE
For some users, it is important to be able to turn off the radio’s display lights, button backlighting, volume
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 light, indicator light and audible 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.
