BATTERY REPLACEMENT
A flashing display is the indication that
the battery voltage has fallen into the
critical region (6.5 to 7.5 V). Reliable
readings can be obtained for several
hours after the first appearance of the
low battery indication.
Open the Battery Compartment and
remove the battery, then install a new
battery and replace the cover.
