Preparations for operation
Before using the instrument for the first time, insert a charged NiMH T4
power pack or batteries approved by Dräger, see chapter "Changing the
batteries" on page 22.
The instrument is now ready for operation.
To reduce the risk of ignition of a flammable or explosive atmosphere, strictly
adhere to the following warning statements:
