3.1 Clean the Unit

Clean the case with a moist, lint-free cloth and a weak detergent. Do not use solvents or abrasive
materials.

3.2 Replace the Batteries

To replace the batteries, refer to Figure B1. Then re-attach the cover.
Make sure that the time and date are correct. The calibration facility uses the date to give service
and calibration messages.
All the other configuration options stay in memory.

4. Calibration

Note: BHGE can provide a calibration service that is traceable to international standards.
We recommend that you return the instrument to the manufacturer or an approved service agent
for calibration.
If you use an alternative calibration facility, make sure that it uses these standards.
