Battery Removal and Replacement
Under normal conditions the battery should last at least two years. It is best
to keep the battery charged as fully as is practical and never store the
monitor with the battery in a discharged condition. When the battery will no
longer take a charge, remove it and replace it with one of the same part
number as outlined below.
1.
Ensure that AC power is removed from the monitor either by removing
the power cord or placing the AC power switch on the rear of the unit to
the OFF (0) position.
2.
Using a dime, or similar tool, loosen the battery door hold-down screws
as shown in Figure 6-1. Turn each screw counterclockwise at least
one-half turn. Do not attempt to remove screws.
