Recharging the GX-2009’s NiMH Batteries

WARNING: To prevent ignition of a hazardous atmosphere, batteries must only be 

changed or charged in an area known to be nonhazardous.

CAUTION:

Use with RKI NiMH battery set 49-1609RK. Charge only with RKI AC charger 
p/n 49-2170RK-0X (where X = 1, 2, 3, 4, or 5) or RKI DC charger 49-2171RK. 
Use of other rechargeable batteries or chargers or charging of other 
rechargeable batteries in the GX-2009 will void the warranty.

1. Verify that the GX-2009 is off.

2. Confirm that the adapter’s DC output cord is plugged into the charger. If a multi-

instrument charging station is being used, the same AC adapter is used as for the single 
instrument charging station. 

3. If using an AC powered charging station, plug the AC adapter into an electrical outlet.
