ALARMS
The audible alarm sounds, once every two seconds, and
the Red LED's flash.
It is strongly recommended the instrument is returned to a
gas free area. Switch the instrument off and then switch
on again in clean air. If the fault persists, return the
instrument for service.
The instrument can however still be used to detect and
alarm on the other sensor(s) fitted. Press the green (RH)
button , as per the screen prompt, to continue.
The faulty sensor will cause the instrument to display a
flashing spanner symbol to warn the user that this sensor
is not working correctly, as shown in Fig. 3.5:
