ppbRAE 3000 User’s GuideNote: A spare Li-ion battery (059-3051-000) or NiMH(059-3054-000) can be charged by placing it directly in the charging port on theback of the cradle. It can be charged at the same time as theinstrument. Press the battery in place, sliding it slightly toward thefront of the cradle. This locks it in the cradle. To release the battery,slide it forward again and tilt it up.Note: An Alkaline Battery Adapter (part number 059-3052-000),which uses four AA alkaline batteries (Duracell MN1500), may besubstituted for the Li-Ion battery.WARNING!To reduce the risk of ignition of hazardous atmospheres, rechargeand replace batteries only in areas known to be non-hazardous.Remove and replace batteries only in areas known to be nonhazardous.Low Voltage WarningWhen the battery’s charge falls below a preset voltage, the instrumentwarns you by beeping once and flashing once every minute, and thebattery icon blinks once per second. You should turn off theinstrument within 10 minutes and either recharge the battery byplacing the instrument in its cradle, or replace the battery with a freshone with a full charge.Clock BatteryAn internal clock battery is mounted on one of the instrument’sprinted circuit boards. This long-life battery keeps settings in memoryfrom being lost whenever the Li-ion, NiMH, or alkaline batteries areremoved. This backup battery should last approximately five years,and must be replaced by an authorized RAE Systems servicetechnician. It is not user-replaceable.108
