Replacement of the rechargeable battery
The rechargeable Ni-MH battery has a high lifespan. However, after a certain time
– depending how it was used – it will loose its capacity and it will make sense to
replace it.
Only use original TECHKON SpectroDens replacement batteries. The use of other
batteries is hazardous!
For opening the battery case you will need a Philips screwdriver type 1.
Place the instrument upside down. Put a soft cloth underneath the display to avoid
any scratches.
1. Unscrew the battery
casing and remove it.
2. Later when reassem-
bling do not tighten the
screw too much other-
wise it might break.
