Further steps
If an error occurred during single-gas calibration, the fault message X is

Charging the battery

To protect the battery, charge only in the temperature range of 5 to 35 °C.
Outside this temperature range, the charging process is automatically
interrupted and automatically continued after the temperature range has been
reached again. The charging time is typically 4 h. A new NiMH power pack
reaches its full capacity after 3 complete charge/discharge cycles. Never store
the gas detector for extended periods without being connected to a power
source (maximum of 6 months) because the internal buffer battery will drain.
The buffer battery can be replaced if necessary.
