• The expected battery service life is 5 years, but the battery may die earlier. It is
strongly recommended that you replace the battery regularly.
• When the battery is replaced, a part of the BIOS settings are initialized. Configure
the BIOS setting again after replacing the battery.
A wrong way of exchange of batteries for the PL leads an explosion. The battery should be
replaced only with the battery recommended by Pro-face.
Before replacing the battery, be sure to turn OFF the PL unit’s power.
Be careful not to cause a short circuit.
Do NOT touch any internal parts except the battery and the battery holder.
During the replacement, be extremely careful not to drop the battery onto the PC board
inside the PL unit. This may cause product failure.
Dispose of used batteries according to the battery manufacturer’s instructions.
