Disassembly
This section describes how to disassemble a C155 telephone. Tools and equipment used are
listed on the preceding page.
Many of the integrated devices used in this phone are vulnerable to damage from electrostatic
discharge (ESD). Ensure adequate static protection is in place when handling, shipping, and
servicing any internal components.
Avoid stressing the plastic in any way to avoid damage to either the plastic or internal
components.
Removing and Replacing the Battery
All batteries can cause property damage and/or bodily injury such as burns if a conductive
material such as jewelry, keys, or beaded chains touches exposed terminals. The conductive
material may complete an electrical circuit (short circuit) and become quite hot. Exercise care
in handling any charged battery, particularly when placing it inside a pocket, purse, or other
container with metal objects.
