POWER SUPPLY

Installing Batteries

Remove the battery door by turning the centerscrew 90° counterclockwise. Insert batteries (or a rechargeable
battery pack) into the housing so that the negative poles are on the larger battery spiral springs.
DO NOT REMOVE RECHARGEABLE BATTERIES FROM THEIR HOLDER AND INSTALL ALKALINE
BATTERIES, SEVERE DAMAGE TO UNIT WILL RESULT IF CHARGING IS ATTEMPTED.
Install the battery door and tighten it by turning the centerscrew 90° clockwise.
A mechanical switch prevents alkaline batteries from being charged. Only the original
rechargeable batterie pack allows charging within the unit. Any other rechargeable batteries
have to be charged externally.

Operating Time

Rechargeable batteries permit an operating time (at 21° Celsius) of appr. 40 hours -HV301; 18 hours - HV301G
in rotation mode.
Alkaline batteries (AIMn) permit an operating time of appr. 90 hours - HV301; 45 hours - HV301G in rotation mode.
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 slow flashing of the battery indicator 8.
Charging rechargeable batteries
The charger requires appr. 10 hours to charge empty rechargeable batteries. For this charging, connect the
plug of the charger to the recharge jack of the unit. New or long time out of use rechargeable batteries reach
their best performance after being charged and recharged five times.
The batteries should only be charged when the laser is between 50° and 104°F (10° to
40°C) Charging at a higher temperature may damage the batteries. Charging at a lower
temperature may increase the charge time and decrease the charge capacity, resulting in
loss of performance and shortened life expectancy.

PROTECTING THE UNIT

Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car).
The unit is very robust and can resist damage if dropped even from tripod height. Before continuing your work,
always check the leveling accuracy. See Accuracy Check section.
The laser is water proof and can be used indoors and outdoors.

CLEANING AND MAINTENANCE

Dirt and water on the glass parts of laser or prism will influence beam quality and operating range considerably.
Clean with cotton swabs.
Remove dirt on the housing with a lint-free, warm, wet and smooth cloth. Do not use harsh cleansers or solvents.
Allow the unit to air dry after cleaning it.

PROTECTING THE ENVIRONMENT

The unit, accessories and packaging ought to be recycled.
This manual is made of non-chlorine recycling paper.
All plastic parts are marked for recycling according to material type.
Do not throw used batteries into the garbage, water or fire. Remove them in compliance with
environmental requirements.
