BATTERY REPLACEMENT

All meters are powered by a 9V battery that is located on the rear of
the instrument.

When the battery becomes weak reaching a certain threshold, the
istrument automatically switches off.

Replacement must only take place in a nonhazardous area using an
alkaline 9V battery.

To access the battery, remove the battery cover by applying pressure
in the direction indicated. Replace the old battery with a new one
while paying attention to its polarity.
