7-4 Cleaning and Storage
1. The panel, rear case, and meter cover are weak to volatile solvents
(such as thinner and alcohol), and therefore should be cleaned with
soft dry cloth or slightly water-damped cloth.
2. The panel and the rear case are not resistant to heat. Do not place the
instrument near heat-generating devices (such as a soldering iron).
3. Do not store the instrument in a place where it may be subjected to
vibration or where it may fall.
4. For storing the instrument, avoid hot, cold or humid places or
places under direct sunlight or where condensation is anticipated.
5. If this unit will not be used for a long period, be sure to remove the
batteries from the unit.
CAUTION
— 53 —
Following the above instructions, store the instrument in good
environment. (See 8.1)
