Slide the battery compartment cover down (9, Fig. 2)

inside the compartment.

either polarity was reversed or the battery contacts are jammed..

 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 could be used to power the System.

after changing the battery (see Compass calibration below for
