Keypad and Keypad Bezel
It is recommended to replace the keypad (9) if the keys are malfunctioning or if there are deep
scratches on the keypad (9). The keypad (9) domes must also be checked for damage, dust or
contamination before changing the keypad (9).
Sometimes the keypad bezel (10) 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
External components on page 25).
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.
