the midday sun).

week.

Use only Alkaline batteries. These may be obtained from PAS Systems
International.

Have the calibration of your unit checked every 6 months, or whenever it
seems to be losing sensitivity.

Allow liquids to enter the inlet or outlet ports.

permanently.

Leave the battery in the unit for days; remove when not in
use.
