7 MAINTENANCE

The A103 telephone is based on highly reliable integrated circuits.
Under normal operation, the telephone is maintenance free with the exception of the BP004
rechargeable battery.
The BP004 is located within the termination chamber. Depending on usage and environmental
conditions a good battery will indicate a no load voltage of between 7.2 and 8 volts.
If the battery needs to be replaced carry out the following:
Isolate the line feeding the A103 so that no power is being applied before removing the
termination chamber cover.
Once the cover has been removed disconnect the battery plug.
Now remove the battery which is held on to the termination cover by two M4 screws, nuts
and washers. Note the nylon washers are located on the outside of the terminal cover to
ensure a good seal is maintained.
Fit the new battery in reverse order remembering to reconnect earth wire and battery plug.
The line can now be reconnected and the A103 telephone functionality checked.
