Replacing Batteries

The C120/CI40 has a dual power supply that consists of main batteries
and a back-up Battery. Be sure to load the main batteries before using
the C 120/C 140 for the first time after purchasing it. Also, replace
batteries as soon as possible after they start to lose power.
Important
•
Never remove both the main batteries and the back-up battery from
the C120/CI40 at the same time. If you do, data stored in memory
can be corrupted or lost entirely.
•
Whenever the main batteries and the back-up battery both require
replacement, be sure to replace the main batteries first, before
replacing the back-up battery.
•
Use two AA-size alkaline batteries or the optional Battery Pack -
NiMH for the main power supply and a CR2032 lithium battery for
the back-up power supply. Never use any other types of batteries
with the C 120/C 140.
•
Be sure to keep track of the battery life of both the main batteries
and the back-up battery. Refer to the User's Guide for information.
If the batteries being used for both power supplies are low at the
same time, data stored in memory can be corrupted or lost entirely.
