232 MONITOR PLUS
General Information
Your 232 Monitor Plus uses two
batteries (both included). The
primary battery is a 9-volt alkaline
cell. Alkaline batteries will provide
the longest and most reliable service.
Should you decide to use a
rechargeable Nicad battery instead,
we recommend that you carry a
charged spare: A Nicad battery can
deliver only about 40% of the
capacity of a fresh alkaline battery.
When the battery is running low you
will receive a BATTERY LOW
warning message on the screen. You
must then change your battery or
plug in the AC adapter. You may
plug in the 232 Monitor Plus
external power supply at any time—
even if the unit is in use.
The second battery contained in this
device is a lithium cell.,used to
preserve memory and menu
configuration. It should provide five
to ten years of reliable power supply.
It is time to replace the lithium cell
when you notice that the 232
Monitor Plus can no longer retain
("remember") either memory or
memory configuration (or both).

Replacing the Lithium Cell
Place the 232 Monitor Plus face
down on a soft cloth and remove the
five (5) cover screws. Remove the
back cover. Carefully remove the
circular lithium cell from its holder,
using the tip of a small screwdriver
to lift the battery up and out of its
holder. Replace it with a BR-
2325–type lithium battery or its
equivalent (3.0V only). Gently refit
the cover to the case and replace the
five cover screws.
