Battery Installation and Replacement
(TM602G/H Models Only)
TM602G and TM602H Telephony Modems may optionally include one of three types
of Lithium-Ion batteries: a 2-cell battery, a 4-cell battery, or an 8-cell battery.
For safety and regulatory purposes, batteries are shipped outside of the Telephony
Modem and must be installed.
Identify the battery type using the photos to the left and use the proper installation
procedure:
• TM602G/H 2-cell Battery Installation and Replacement
Note: The 2-cell battery may be light grey or black.
• TM602G/H 4-cell Battery Installation and Replacement
Note: The 4-cell battery is longer than the 2-cell battery, and has a strap
between the guides.
• TM602G/H 8-cell Battery Installation and Replacement
Note: The 8-cell battery replaces the battery door, and increases the height
of the Telephony Modem by about 5/8inch (16 mm).
