Sepura SC20 series Service Guide

Keypad and Keypad Bezel
It is recommended to replace the keypad if the keys are malfunctioning or if there are deep scratches
on the keypad. The keypad domes must also be checked for damage, dust or contamination before
changing the keypad.
Sometimes the keypad bezel is changed to another colour, for example for the purpose of identifying
the radio as belonging to a certain group of operators. Note that this procedure is also used when
changing the coloured keypad bezel (see Spare parts list on page1).
Caution! Fragile item. Handle the keypad and keypad bezel with care. Do
not use force to remove or refit the keypad - the snap hooks on the keypad
bezel can be easily broken under force.
