OPERATION
TO INSTALL/REMOVE BATTERY PACK
See Figure 4.
The radio's battery port will accept RIDGID  V, 4.4 V and
8 V NiCd battery packs and 8 V and 4 V Li-ion battery
packs. The 8 V Li-ion battery pack is shown.
NOTE: Do not attempt to use the 9.6 V RIDGID slide-mount
battery pack with the job-site radio, as it will not power the
unit.
 Place the battery pack in the radio, aligning the raised rib
on the battery pack with the groove in the radio's battery
port.
 Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured to the
radio before beginning operation.
 Depress the latches on both sides to release the battery
pack from the radio.
NOTE: Leaving the battery pack connected for long
periods of time will drain the battery pack. Always
disconnect battery packs after use.
12 V DC 1-AMP RECEPTACLE
See Figure 5.
The  V DC receptacle can be used as a power source
for powering small, low current (less than  [one] Amp DC)
devices such as cell phone chargers, CD players, etc.
CAUTION:
Do not connect any devices that require more than
 (one) Amp to operate. Doing so will trip a self-
resetting function and disable the receptacle.
CAUTION:
Output wiring of the receptacle is center positive.
Make sure the device you wish to connect has a
compatible connector as shown in figure 5.
NOTE: When charging small electronics through the  V
receptacle, be sure the battery pack inserted in the radio
is greater than  V, or plug the radio into a power supply
using the A/C cord.
WARNING:
Always keep the  V DC receptacle covered with
the receptacle cover when not in use. Failure to
heed this warning could result in serious injury.
