7.1 Battery replacement
If the batteries are discharged and only a reserve operating time remains, the
battery symbol on the display changes (for detailed information please see the
maintenance section in the separate operating manual). The batteries should
be replaced afterwards in order to ensure safe operation.
It is advisable to change all 2 batteries at the same time.
The batteries must only be changed outside the ex-area. Only the appropriate,
approved types of batteries may be used (refer to the table 1 with details of the
type-tested batteries under point 6: Technical data).
Please follow additional instructions:
• Remove all probes, test leads and accessories before the battery door is
opened.
• Do not disassemble the batteries.
• Weak batteries should be replaced immediately.
• If any spilled electrolyte is noticed while changing the batteries do not
take the unit back into the Ex-area but send it to the manufacturer for
inspection.
• Remove batteries to prevent battery leakage and damage to the Product
if it is not used for an extended period.
• Be sure that the battery polarity is correct to prevent battery leakage.
• Do not short the battery terminals together.
• Do not disassemble or crush battery cells and battery packs.
• Do not keep cells or batteries in a container where the terminals can be
shorted.
• Do not put battery cells and battery packs near heat or fire. Do not put in
sunlight.
Note:
The batteries should be replaced in less than one minute after removal to
avoid manually re-initializing the thermometer clock and date.
To install or change the two AAA batteries (see Figure 10):
1. Remove leather grip LH568
2. Slide the locking tab on the battery door to the "unlock" position and then
open the handle.
3. Insert the batteries noting their correct polarity.
4. Close and lock the handle.
5. Put the leather grip back over the battery door.

9 Cleaning, maintenance and storage
• Only use a suitable cloth or sponge to clean the unit. Do not use solvents
or abrasive cleaning agents, particularly the lens, for cleaning.
• We recommend having the function and the accuracy of the device
checked by the manufacturer every two years.
• The batteries should be taken out of the unit if it is to be stored for extend-
ed periods.
• The storage temperature should be within the permitted range of -20 °C
to +60 °C
(without batteries).
Cleaning the lens:
Blow off loose particles with clean air. Remaining contamination is then remo-
ved carefully with a soft brush. Wipe the surface carefully with a moist swab.
The swab can be moistened with water.
