Preparations
Important
Take care not to reverse the (+) and (-) polarity when insert-
ing a battery.
Always use four identical batteries, and replace batteries
only as a set. Mixing battery types or old and new batteries
can lead to damage.
Remove the batteries from the unit if it is not to be used for a
week or longer.
When the battery voltage drops near the operation limit of the unit, the indication LOW
appears on the display.
In this case, replace all four batteries with fresh ones at the earliest opportunity.
When the battery voltage drops even further, the indication EMP flashes on the display.
You must immediately replace all four batteries with fresh ones if you want to continue
using the unit.
