POWER SUPPLY
Before using the unit for the rst time, install alkaline or rechargeable batteries. If Ni-Cads are used, rst
recharge the batteries. See battery section.
The Ni-Cad and Ni-MH batteries may contain small amounts of harmful substances.
Be sure to charge the battery before using it for the rst time, and after not using it for an
extended length of time. Charge only with speci ed chargers according to device manufacturer’s
instructions.
Do not open battery, dispose of in re or short circuit; it may ignite, explode, leak or get hot causing
personal injury.

Installing Batteries
Remove the battery door by turning the center screw 90° counterclockwise. Insert batteries (or a rechargeable
battery pack) into the housing so that the
negative poles are on the bigger battery spiral springs
.
Install the battery door and tighten it by turning the center screw 90° clockwise.
A mechanical switch prevents alkaline batteries from being charged. Only the original rechargeable
battery pack allows charging within the unit. Any other rechargeable batteries have to be charged
externally.
Operating Time
Rechargeable batteries permit an operating time of approx. 45 hours in rotation.
Alkaline batteries (AIMn) permit an operating time of approx. 90 hours in rotation.
The following factors reduce the operating time:
frequent self-leveling due to wind or vibration;
extreme temperatures;
old rechargeable batteries or rechargeable batteries with memory-effect;
using batteries of different capacities.
Remove all batteries at the same time. Never use batteries with different capacities. Only use new
(charged) batteries (rechargeable).
Low voltage is indicated by the slow  ashing battery indicator (5).
