POWER SUPPLY

Before using the unit for the first time, install alkaline or rechargeable batteries. If Ni-Cads are used, first 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 first time, and after not using it for an extended length of time. Charge only with specified chargers according to device manufacturer’s instructions.

Do not open battery, dispose of in fire or short circuit; it may ignite, explode, leak or get hot causing personal injury.

Dispose in accordance with all applicable federal, state, and local regulations.

Keep the battery away from children. If swallowed, do not induce vomiting. Seek medical attention immediately.

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 flashing battery indicator (5).
