Disassembly

This section covers the assembly and disassembly of SLT100 phone. In order to carry out the assembly or disassembly the following precautions should be taken:

1. A Plus screwdriver is required to remove the four retaining screws, which holds the two casings

together. Ensure that the screwdriver is narrow enough to reach the screws without causing damage to the casing parts.

2. The phone should always be placed on a soft surface to minimise the risk of damage being

caused to the casing, window and keypad. If the PCB is to be removed, then care should be taken

not to stress or scratch the exposed LCD.

3. Observe anti-static precautions when handling the main PCB or any of its components.

4. Repairs carried out by unauthorised persons will result in the warranty on the unit becoming

void.

5. Do not use solvents to clean any of the casing parts or the LCD window.
