CAUTION
• Do not turn off the indicator/alarm unit during the initial clear.
• If a new sensor is installed or the sensor is replaced after the indicator/alarm unit is started, the
sensor must be warmed up for a specified period which is determined depending on the type of
the sensor. After the warm-up is completed, perform a gas calibration. Read also the operating
manual of the gas detector head.
• During the warm-up, the alarm activation and output signals are unstable. Provide a prior
notification to the related sections so that they can prepare for false abnormalities.
