BATTERY REPLACEMENT
If "LO BAT" appears on the display, it is an
indication that the batteries are running down.
If it appears during printing, approximately
200 printouts can still be made before the
batteries are exhausted. When there is only sufficient power for 100
printouts, the "LO BAT" sign is displayed continuously on the LCD.
Battery replacement must only take place in a non-hazardous area
using alkaline AA type 1.5V batteries.
In order to replace run down batteries, simply remove the two screws
on the rear cover of the instrument and replace the four 1.5V AA
batteries with new alkaline ones, paying attention to the correct
polarity.
