Cleaning
The body of the transmitter can be cleaned by wiping with a moistened lint-free
cloth. Do not use cleaning agents or solvents, or blow pressurized air into the
transmitter housing.
If you suspect the CO
2
measurement module is dirty, do not
attempt to open it. Instead, replace it with a new part. For order
codes of spare parts, see Spare Parts and Accessories on
pageî38.
