8 Care and maintenance

8.1 Cleaning and drying
1. Blow dust off the surfaces.
2. Do not touch the display areas or the receiving
window with the fingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Do not use any other liquids as these may
damage the plastic components.
4. Observe the temperature limits when storing your
equipment. This is particularly important in winter
/ summer if the equipment is kept inside a motor
vehicle (-40°C to +70°C / -40°F to +158°F).
8.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at maximum 40°C / 104°F). Repack
the equipment only once it has dried completely and then
store it in a dry place.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
