Any alarm will cause the backlight to be switched on automatically.
Latching Alarms (default)
In the latched condition, once an alarm occurs, both audible and visual alarms continue to operate even after atmospheric hazard has cleared. Pressing any of the instrument buttons will clear an alarm. Any subsequent alarm will reactivate the audible and visual alarms.
In this mode, should a gas alarm occur, the instrument would enter an alarm condition. When the reading returns to normal levels, the audible and visual alarms will stop.
Vibrating Alarm
Any alarm condition that activates the audible and visual alarms will also activate the
Resetting an Alarm
If an alarm condition occurs, it is possible to cancel the alarm by pressing any of the buttons, once the gas measurements have returned to a safe level. Otherwise, the instrument will remain in the alarm condition, but the audible alarm will be muted. Any subsequent alarms that occur 1 second after the previous alarm has been reset will reactivate the audible alarm.
Fault & Warning Conditions
In addition to the gas alarms, the gas detector includes a number of auxiliary alarms to safeguard proper use of the instrument. At switch on, the gas detector performs an electronic
CAUTION

MAINTAINING POWER SOURCES
Portable Four Gas Detector is supplied with rechargeable battery. To charge the battery, ensure that the basestation is connected to a suitable power
source. Place the instrument in the basestation. The basestation employs a locking system to ensure that the gas detector is retained under most operating
conditions. To ensure this operates correctly, ensure that the gas detector is orientated such that the instrument lip will be inserted
under the locking lip and
rear locking catch. Whilst charging, the instrument will flash two red LEDs every 10 seconds. When charging is complete it will light the green LEDs
constantly. A fully discharged battery will typically require 7 hours to recharge.
To remove the Gas Detector press down on the rear locking catch.
Ensure the DC power supply adaptor is connected to the ‘IN’ socket on the underside of the basestation.
WARNING
Do not charge the battery pack in a hazardous area
