3.2 Charging the Battery
W ARNING : Never charge the TARGET instrument in a hazardous location
The TARGET instrument has a 4.8 volt, nickel metal hydride (NiMH) battery pack. The supplied battery charger charges
the instrument batteries usually in three to four hours. The charger is supplied with a power cord for connection to 110
VAC wall outlet. The batteries may also be charged in the same time frame with a 12 VDC vehicle accessory adapter.
Instrument electronics protect alkaline battery packs from being charged by the
TARGET battery charger.
N OTE : The connector is keyed and will only go in one way.

Example: Display, Charging Complete
N OTE : While charging the batteries, the instrument enclosure becomes warm to the touch. The instrument electronics
detect peak battery charge and stop charging at the appropriate time. Once charging is complete, the enclosure will
cool to room temperature.
The instrument may be left indefinitely on the charger. It is recommended to do so, to keep the battery pack at full
charge.
C AUTION : When removing the charge jack be sure to grab onto only the ribbed portion of the connector, otherwise the
connector will not release. See Figure 7.
