Recharging the GX-2001’s Battery Pack
WARNING: To prevent ignition of a hazardous atmosphere, batteries
must only be changed or charged in an area known to be
nonhazardous.
CAUTION: To be used with RKI Ni-cad battery pack p/n 49-1602RK or Ni-
MH battery pack 49-1605RK. Charge only with RKI charger p/
n 49-2155RK, 49-2156RK, or 49-2163RK.
1. Verify that the Model GX-2001 is off.
2. Plug the battery charger’s AC power cord into an electrical outlet.
NOTE: Two of the three GX-2001 chargers, the 49-2155RK and 49-
2156RK, may be powered from 100-240 VAC 50/60 Hz. The 49-
2163RK may only be powered from 100-120 VAC 50/60 Hz. The
49-2156RK has a PC communication feature for data
downloading. See “Parts List” for more information.
3. Place the Model GX-2001 in the battery charger.
4. While the unit is being charged, the red LED on the top face of the
charger is on.
5. When the red LED turns off, the GX-2001’s battery pack is fully
charged. It takes approximately 90 minutes to recharge a fully
discharged battery pack.
6. To verify whether the battery pack is fully recharged,
remove the unit from the battery charger, then press the
MODE/POWER button to start up the unit. If the battery
icon on the LCD is fully colored in, then the unit has been
completely recharged.
NOTE: A battery pack will have a typical service life of 500 charging
cycles minimum.
When using the GX-2001, be sure to drain the battery as much as possible
before recharging. If the battery is regularly only partially drained before
charging, the battery will experience a “memory effect” and the run time of
the instrument will be decreased.
