Changing battery

To install a battery:

Slide the battery compartment cover down (Fig. 2)

Install the battery, observing correct polarity

Do not force the battery while placing back inside the compartment.

Close the compartment cover

If the battery does not fit the compartment easily, it means that either polarity was reversed or the battery contacts are jammed.

To remove battery:

Slide the battery compartment cover down (Fig. 2)

Shake the rangefinder gently towards the open end of the battery compartment

Pull out the battery

The unit is fully operational when battery voltage is higher than 6.2V. A ‘LOW BATTERY’ warning is displayed when battery voltage falls below 6.5V.

Ni-MH rechargeable batteries capable to sustain current drain up to 250 mA can be used to power the unit.

Note: Non-magnetic batteries should be used for peak compass performance. If a non-magnetic battery is not used, you may need to calibrate the unit after changing the battery (see Compass calibration below for more details).
