Inserting/Changing the Battery

It is recommended that you use alkaline manganese non-rechargeable batteries to operate the voltage tester.

  1. Unscrew the battery compartment cap (5).
  2. Insert the non-rechargeable batteries.
Always replace all the non-rechargeable batteries at the same time. Only use non-rechargeable batteries from the same manufacturer and which have the same capacity.
Make sure that the polarity is correct and corresponds to the sideward diagram on the voltage tester.

If the batteries are drained, an audio signal will sound, both LEDs ((7)/(8)) will flash, and the voltage tester will switch off.
