Recharging the Battery

To make the best use of the battery and prolong its service life, observe the
following rules.
• Use only the battery charger supplied with the unit; other chargers may be
hazardous!
• Recharge the battery only at temperatures between 32° and 104°F (0° and
+40°C).
• Observe the conditions of use and storage defined in the specifications.
Even an NiMH battery can be recharged only a limited number of times. This num-
ber, and thus the service life of the battery, is highly dependent on the following
factors:
• the operating conditions
• the recharging conditions
As the earth tester might go some time without use and the battery has a natural
tendency to run down, you should check the battery level at regular intervals. To do
this, turn on the unit and check the battery level indicator
display. If there is only one bar in the symbol or if there are no bars at all, the bat-
tery should be recharged.
