Batteries and Charging
The Hellfire operates on 10 ‘AA’ batteries. For optimal performance, FOXPRO recommends the
use of high-capacity 2000 mAh or greater NiMH (Nickel Metal Hydride) rechargeable batteries
rather than alkaline types. You can find compatible charging systems available from FOXPRO on
the FOXPRO website at: http://www.gofoxpro.com
When you ask the Hellfire to play at extremely loud volume levels, the current demand on the
batteries is much more than alkaline cells can deliver. Consequently, the run time of these
batteries can be very short. The Zinc Carbon (so-called “Heavy Duty” cells) are expressly not
recommended. The performance of the Hellfire will be much better with high-capacity NiMH
batteries.
On the back of the Hellfire, you will notice the amber LED. This is the pilot lamp, but also serves
as the low battery indicator. When this light begins to blink during operation, it is alerting you
that the batteries need recharged (if using rechargeable batteries) or replaced (if using alkaline
batteries). If the batteries drop too low to power the Hellfire, it will shut itself off. Battery run
time is going to depend on many factors including how loud you are operating it.
WARNING
Do not mix battery types!
For example: never use NiMH rechargeable batteries in
conjunction with non-rechargeable alkaline batteries.
WARNING
Never connect your Hellfire to an unregulated 12V system (i.e. automotive systems,
high current power supplies, etc.)
Serious damage will occur which is not covered by
the warranty. The charge jack is intended only for FOXPRO
®
chargers.
CHARGING RECOMMENDATIONS
•
Never attempt to charge batteries that are not intended to be recharged!
This includes both Zinc Carbon and alkaline cells. The resulting damage can
be serious and will not be covered by the warranty.
•
Never attach an unapproved or a non-FOXPRO
®
charger to your Hellfire!
Damages caused by plugging unapproved charging devices into your Hellfire
will not be covered by warranty.
•
Remember that NiMH batteries self-discharge about 1% per day.
•
Do not leave charging batteries unattended.
•
Remove batteries from battery holder when caller will not be used for
prolonged periods to help prevent deep discharge.
•
Recharge your batteries periodically—even when not in use—to prevent
deep discharge.
