10. Battery change

If the device is not used for a long time it may occur that the two O-rings beneath the
handle stick to the surface and the handle only comes off after jerky anticlockwise
rotation.

The UWEX 722 can be operated by a dry alkaline (6LR22), by a dry lithium (U9VL)
battery or by a rechargeable NiMH battery of PP3 style. Operating time of the dry
alkaline battery is approx. 20 h. Lithium batteries will provide approx. double the
operation time.
The lithium battery UV 9L is has a minimised magnetic signature, better temperature
range, improved storage life and much higher capacity and should be considered
superior to alkaline batteries.
Rechargeable batteries must be serviced according to manufacturer instructions. Do not
use for more than 1 - 2 hours between charges.
After the battery exchange the handle must be refitted. The surface of the sealing ring
has to remain clean. For correct sealing it is sufficient to tighten the carrying handle hand
tight as the O-rings are a radial seal. Do not force handle to avoid damage to the
equipment. Use silicone grease to service the O-ring and thread occasionally.
The detector has to be switched off after use to avoid leakage or damage of the
rechargeable battery due to complete discharge.
If the detector is not used for a longer period remove battery.
