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).
