1.3 Charging
Chargingshouldonlytakeplaceinnon-hazardous(safe)areas.Tocharge,simplyplugthecable into the charging socket
on the Gas-Proandturnonthemainssupply(seeFigure2below).Ifachargingcradleorvehiclecradleisbeingused,
ensure the Gas-Protsrmlyontothepowerconnector.
Thechargermustbeabletosupply6.5V@450mAwithanoutputvoltagethatdoesnotexceed9.1V(Um).
Figure 2: Charger connection
Whenoff,toshowtheGas-Proischarging,bothLEDswithinthealarmbarswillashredandwillchangetogreenonce
fully charged. This state will continue until the trickle charge is complete. Charging will then terminate showing no indication.
ThescreenwillalsoshowthebatteryiconllinginthemiddleofthescreenwhentheGas-Proisoff,andinthebottomleft-
hand corner when it is on. The battery icon contains a maximum of six segments to indicate the battery’s state of charge. For
example,withthreesegmentsshownandafourthashing,thebatteryis50%charged ,andwhenallsixareshown,the
battery is fully charged (see Figure 3 below).
