Power is supplied by a 9 volt, PP3 battery.
The battery sign appears on the LCD display
when a replacement is needed. To replace the
battery, remove the three screws from the back
of the instrument and lift off the front case.
Exchange the battery in the protection tube
located at the top of the rear cover. Replace
the instrument front squarely with the rear
cover and secure with the three screws.
