6.17 ADJUSTING DISPLAY & 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.
6.18 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.
6.18.1 Enabling Stealth Mode
1. Using , scroll through the menu until “StealthMenu” appears.
2. To immediately turn stealth mode on, press up or down with .
3. To turn stealth mode off, press any button on the radio’s front panel.
6.18.2 Disabling Stealth Mode
Pressing any radio button other than the mic’s PTT button or the emergency button on front panel will
immediately turn stealth mode off. For example, pressing the MENU button on the front panel will turn
stealth mode off.
With stealth mode on, pressing any radio button (other than the mic’s PTT button
or the emergency button) on the front panel will immediately turn stealth mode off.
6.19 ADJUSTING SIDE TONE AUDIO LEVEL
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned
completely off using the “Side Menu.”
For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio
during covert operations is not recommended.
To temporarily disable the side tones that could expose the user’s presence and position, use the menu
buttons to access the “Side Menu” and select “Off” from the menu choices.
