e) Replacing the button cell battery
If the date and time are no longer correctly displayed, the button cell battery must be replaced.
Proceed as follows to replace the button cell battery:
1. Remove the attached test leads from the measuring circuit and from your measuring device. Turn
off the DMM.
2. Open the battery and fuse compartment as described in Section "c) Opening the measuring de-
vice" (page 76).
3. Then loosen the four screws on the back of the device and carefully remove the housing.
4. Carefully push the button cell battery out of the battery holder from below. Lift the battery holder
slightly upwards while doing so.
5. Replace the used button cell battery with a new one of the same type (CR2032). Insert a new
button cell battery into the battery compartment. Make sure that the plus pole points upwards.
6. Close the housing in the reverse order and screw closed the battery and fuse compartment.
You can order a suitable button cell battery using the following part number:

24. DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household
waste.
At the end of its service life, dispose of the product according to the relevant statutory
regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from the
product.
b) Batteries / Rechargeable batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/rechargeable
batteries. Disposing of them in the household waste is prohibited.
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) batteries,
e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.
25. TROUBLESHOOTING
