Sepura SC21 Series User Manual

Day/Night mode
When a call or message is received, and when you press any key, the backlight lights up the display
and keypad. A bright display can be a potential distraction, particularly when driving at night or in
poor lighting conditions. Day/Night mode lets you adjust the intensity of the backlight and keypad
illumination to suit your working conditions. Night mode reduces the glare from the display, making it
ideally suited for night time use.
When the preferences for day and night mode have been set, switching between the modes
automatically adjusts the backlight and display settings.
A soft key may be customised to switch between Day/Night mode.
To change Day/Night mode settings
1. Select Menu > Options > Settings > Display Settings > Day/Night Mode.
2. Scroll to each option (highlight it) to make your adjustments:
Day Mode—to toggle between Day Mode and Night Mode press the Toggle context
key.
Backlight Enabled—to toggle the backlight on/off press the Toggle context key.
When a tick appears in the box, the backlight is on, and when the box is empty, the
backlight is off.
Backlight Level—to adjust the intensity of the backlight and the key pad illumination on
a scale of 1 to 7 .
Adjusting text and icon size
Your radio uses the default size for the text and icons set during customisation, however it also
supports a number of different size modes that control how text and icons are displayed, which can
make them easier to see from a distance.
NOTE: When selecting larger modes, some prompts or icons may not appear on the
radio display.
Your radio supports the following modes:
Normal Mode allows the maximum amount of information available to be displayed in a compact
character size.
Large Mode displays screen information in a large character size.
Very Large Mode displays the talkgroup number or talkgroup name, as customised, in an extra
large size on the Home screen with all other screens in Large mode.
Custom displays the Home screen, menu and WAP browser in predefined text sizes set during
customisation. Only the Home screen supports Very Large mode, with other screens set to either
Normal or Large mode.
