BATTERY INSERTION AND REMOVAL
The binoculars are powered by a CR2 3V battery. Before using
the binoculars, unscrew the battery compartment cover located
in the central focus adjustment knob by turning it counterclockwise.
If the battery is pre-installed, remove the plastic pull tab from
between the cap and the battery.
If there is no battery, insert it with the correct polarity (see the marking
on the battery compartment cover). Turn the battery cover clockwise.
At 20 °C the new battery is sufficient for approx. 2,500 measurements.
However, depending on the conditions of use, e.g. in lower temperature
or in case of more frequent use of the continuous measurement (scan)
mode, the battery life can be significantly shorter. Be sure to check the
battery indicator on the display.
If the device is not used for a long time, the battery should be removed
to avoid damage caused by leakage. Please use only high-quality
batteries.
