Charging the battery
The installed battery should be charged before the device is used for the first time. To do so, insert the
charging adapter provided into the 7-pin socket on the HD2. Then connect the power adapter to the
charging adapter. Charging commences immediately if the HD2 handheld device is already switched
on or the battery is over-discharged. Otherwise, switch on the HD2 by pressing and holding the "Meas-
ure" key
for approximately 1 second. An animated battery symbol on the display indicates that
charging is active.
The built-in charging electronics charge the battery until it is fully charged. Charging takes around
2 hours if the battery was fully discharged. As soon as the battery is finished charging, all 4 "battery
bars" appear permanently on the display screen and trickle charging commences.
Caution:
Only charge the battery at room temperatures (approx. 10°C to approx. 30°C)! If
the temperature is too low, end-of-charge cutoff might not work correctly and the
battery may be overcharged. If ambient temperatures are too high, the HD2 can
be damaged by the heat generated during charging.
