Batteries and Charger
1. Insert one of the power cords into the back of the
drop-in charging cradle.
2. Insert the other end of the power cord into the
appropriate 12 or 120 volt power source.
3. Insert the radio into the charger. The metal pads
on the radio will contact mating pads in the charger
to transfer the charging current.
4. Observe that the red light on the front of the charger
glows to indicate that the radio is properly seated and
the charger is operating.
5. Allow the batteries to charge for 12 to 15 hours.
NOTE
If the drop-in charger is to be used on a boat,
Cobra
®
recommends you attach it to a shelf or
bulkhead (using the screw holes provided) to
prevent damage due to the boat rolling or pitching.
Maintaining the Battery Charge
As you use your radio, the battery power icon will
show the battery power remaining. When the icon
shows only one or no segment, it is time to recharge
or change the batteries.
You can monitor incoming calls while the radio is
charging. However, you should remove it from the
charger to transmit. Charging will be quicker if the
radio is turned Off.
CAUTION
Use only the drop-in charger provided by Cobra
®
.
Do not use the charger with alkaline batteries; only
the NiMH batteries are rechargeable. Spent alkaline
batteries must be discarded and replaced.
It is a good idea to keep a set of fresh, high quality
alkaline batteries with your radio. Should the rechargeable
batteries become discharged and no electrical power
source be available, you can insert the alkaline batteries
and continue to use your radio until you can return to
using the rechargeable ones.

Replacing the Batteries
When your rechargeable batteries begin to
discharge too quickly, it is time to install new ones.
1. Obtain six (6) replacement AA size NiMH
batteries. (See Optional Accessories page 46.)
2. Open the battery compartment by turning the
screw counter-clockwise one-quarter turn.
3. Slide the battery holder out of the radio and
remove the old batteries.
4. Install the new batteries in the holder.
Be sure to match the polarity markings
on the batteries with those on the tray.
5. Insert the battery pack in the radio.
6. Close the battery compartment by turning
the screw one quarter-turn clockwise.
CAUTION
The gasket on the base of the battery pack is
essential for the radio to be waterproof. Be certain
that it is not dislodged while changing the batteries
and fits properly into the radio.
CAUTION
NiMH batteries are toxic. Please dispose of the
old ones properly. Some marine suppliers accept
old batteries for recycling and many municipal
waste disposal agencies have special provisions
for battery disposal.
