3.2 Charging the Battery
WARNING: 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 TARGETbattery charger.
NOTE: The connector is keyed and will only go in one way.
♦ Grasp by ridged portion of connector
♦ If cable is pulled connector may be damaged

Plug the battery charger into the wall and then plug the charger connector in to the I/O and charging port on the front of the TARGETinstrument. See figures 6 and 7.
Once inserted, the instrument’s display activates and shows the charge status:
When the batteries are fully charged, the following is displayed providing information on charge time, capacity and status:

NOTE: 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.
CAUTION: 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.
