Battery Installation and Replacement (TM402G, TM402H, and
TM402P models only)
These models of the Telephony Modem have the ability to provide battery backup
in the event of a local power loss. The battery backup is not intended to take the
place of AC power. Depending on the model, one or two lithium-ion batteries can
be inserted into the Telephony Modem. The TM402P (depicted at the left) supports
two batteries If you are only using one battery, it must be inserted into Bay 1. The
TM402G and TM402H (not shown) only has support for one battery. Use this pro-
cedure to install and to replace the backup batteries.
Action
1
Pull down on the two latches holding the battery door (on the bottom of the
Telephony Modem) and pull the door toward you. Set the door aside in a safe
place.
2 Hold each battery by its pull tab and insert the batteries into the bay. The
photo on the left shows the proper orientation. Batteries will not insert com-
pletely into the Telephony Modem if not oriented correctly. Remember, with
the TM402P if only one battery is being used, it must be inserted into Bay 1
as shown on the left.
