Personalising your radio
You can personalise your display settings (such as text size, backlight, inverting the screen and
change languages) and create a personal phone book containing your own contacts.
Invert the display
When you are wearing the radio on your shoulder, attached to a belt or to a body vest, you may want
to flip the display upside down to make it easier to read. The Invert Display option rotates all screen
elements by 180 degrees.
This feature is commonly assigned to a soft key or SmartMenu.
To invert the display:
1. Select Menu > Options > Settings > Display Settings > Invert Display.
2. Press the Toggle context key. When a tick appears in the check box, the display is flipped, and
when the check box is empty the display is set to normal.
When the display is inverted, the navigation keys work in opposite to their normal function. Press the
Up key to scroll down and the Down key to scroll up. The Right key to scroll left and the Left key to
scroll right.
Adjusting the backlight
When a call or message is received, and when you press any key, the backlight lights up the display
and keypad. The length of time the backlight illuminates is set during customisation.
To adjust the backlight:
You can toggle the backlight on/off by using a soft key or from a SmartMenus on page23 (if
customised).
Alternatively:
1. Select Menu > Options > Settings > Display Settings > Backlight.
2. Press the Toggle context key.
