Battery
When there is low battery indication show on the screen, or the detector will not power on due to low voltage
charge the battery.
In power off situation, connect the charger head with AC 100~230V power. Then connect the charging cable
with the detector. The detector will power on automatically and display as charging status. Battery charging is
completed when the battery indication icon is full and not changing. Then you can unplug the charger and
disconnect the detector. Then the detector can be put into use.
Warning
: It is not possible to power on the detector when charging the battery while powered off. Please do not
charge the battery in the field. In case the plugging/unplugging of the charger head may cause sparks and then
lead to fire or explosion. Charging the battery while the detector is powered on will have a reduced charging
speed.
