78  Customizing your radio
About display and keypad 
backlighting
Whenever a key is pressed or a call is received, the 
keypad and display light up automatically to make it 
easy to read in poor light conditions.
Backlighting usually remains on for a few seconds, 
unless further radio activity is detected. The period of 
time that the backlighting remains on once no further 
radio activity is detected is determined by the 
backlighting timer. The duration of this timer is set 
when the radio is programmed.
The radio’s display can also be made darker or lighter to 
suit your working conditions. See 
“Adjusting the display 
contrast” on page 79.
