Charging Radio Pack Batteries
Radio Packs are powered with (1) Lithium-Polymer rechargeable battery for greater than 9 hours (900MHz), or they may be
powered with (3) AA Alkaline batteries for approximately 4.5 hours (900MHz).
The batteries can be charged either inside the RP with an external power supply or by using the 5-Bay rapid charger.
The batteries require approximately 3 hours to charge from empty. Take care to insert the battery into the RP with the
contacts facing down and oriented such that the contacts on the battery will line up with the contacts inside the RP battery
compartment.
To charge the RP, connect the plug-in battery charger (included with RP) to a standard wall outlet and to the Micro-USB
connector on the RP. The connector is located under the rubberized access cover on the side of the RP. The battery may also
be charged inside the RP via the USB port of a computer.
Up to five (5) CoachComm lithium-polymer batteries may be charged at the same time using the 5-Bay charger. If charger(s)
overheats, it will need to be moved to a cooler area to charge batteries properly. As a lithium-polymer battery safety
mechanism, the battery chargers include a safety circuit, which prevents charging of batteries if the ambient temperature is
too hot. For the batteries to charge in the 5-Bay charger, there must be external AC power.
If using three (3) AA batteries, CoachComm recommends that only major brand, standard batteries should be used for
maximum reliability and effectiveness. You should expect approximately 4.5 hours (900MHz) of operation using new AA
batteries.
There are several considerations you should take into account when using AA batteries. The RP’s battery level and
remaining battery time indicators only reflect battery life for lithium-polymer batteries; therefore, those screen options will
not be used when AA batteries are in use. In cold weather, AA batteries do not release their stored energy completely, so
the result is a dramatic reduction in operation time. It would not be uncommon to have an AA battery only last 50% of its
original life when used in very cold situations. Also, remove the AA batteries when not in use to avoid potential damage from
leaking battery acid that can sometimes occur in these type batteries.
Installing a Radio Pack Battery
1. Before powering on an RP, install its battery by doing the following:
A. Press the battery-release button on the rear of the battery pack to
unlatch the battery door.
B. Depress the RP’s belt clip to access and remove the battery door.
C. Install a fully charged Lithium-Polymer rechargeable battery or
three AA batteries into the RP. Then, place battery door back on
the RP.
2. Turn on the RP by pressing and holding the Power button on the back
of the pack for 3 seconds.
Note:
The RP will not operate unless it has been paired to a Control
Unit; if it has not been paired it will indicate “No Pairing
Information Available” on the pack’s display.
