Replacement of the rechargeable battery
The rechargeable Li-Ion battery has a high lifespan. However, after a certain time it will
loose its capacity and it will make sense to replace it.
Only use original TECHKON DENS replacement batteries. The use of other batteries is
hazardous.
For opening the battery case you will need a TORX™ screwdriver type 6.
Place the instrument upside down and put a soft cloth underneath the display to
avoid any scratches.
1. Unscrew the three TORX™ screws on the
device bottom and remove the upper device
case.
2. Unscrew the two TORX™ screws of the bat-
tery holder and remove the holder.

3. When exchanging the battery take care of
the correct position of the battery contacts.
Refit the battery holder to the circuit board
and finally fix the device case.
4. When reassembling do not tighten the
screws too much otherwise they might break.
