FR300 OPERATION MANUAL
AA BATTERY OPERATION
The FR300 is designed to operate on three AA batteries (not included).
Best overall performance results with the use of alkaline or lithium AA
batteries. Rechargeable AA batteries can also be used, however they
must be charged in their own external charger. Lithium AA batteries
are more costly and harder to find, yet provide two to four times the
playtime of alkalines and provide a much longer shelf life.
Install the batteries by removing the battery compartment cover and
following the battery polarity diagrams imprinted on the underside of
the cover. Remove the cover by simultaneously pressing on the inden-
tation labeled OPEN and pulling it. To play the FR300 on its AA bat-
teries, turn the radio on by setting the power selector switch to the
BATTERY position.
NOTE: When an AC adaptor is in use, the AA batteries are automati-
cally switched off and may be left in.
PREVENTING BATTERY ACID LEAKAGE
To avoid battery acid leakage, only use high quality alkaline, lithium
or rechargeable nickel-metal-hydride batteries. Never intermix old
with new, or different brands or types of batteries. Damage caused by
battery acid leakage is not covered by this product’s warranty. If the
batteries leak, don’t throw them away and immediately contact the
manufacturer of the batteries to inquire about their battery leakage
warranty program.
EMERGENCY OPERATION WITH NO POWER SOURCE
Even if no power source is available, including the Ni-MH battery
pack, the radio and the light can still be operated by continually
turning the dynamo crank with the power selector switch in the
DYNAMO/ADAPTOR position.
USING AN EXTERNAL POWER SOURCE AND NI-MH
BATTERY CHARGING
The FR300 can be powered via an AC adaptor/charger (not included).
Using an AC adaptor/charger automatically charges the internal Ni-MH
battery pack. If the adaptor/charger meets the correct specifications it
can be left plugged in without damaging the Ni-MH battery pack.
When the battery pack is depleted it takes about 8 hours to charge it
using the proper AC adaptor/charger. The Ni-MH battery pack will
take charge with the power selector switch set to any of its positions.
While charging, the red LED charging light will be on (top left of
FR200).
For proper operation, the AC adaptor/charger must meet the specifi-
cations described below.
AC ADAPTOR/CHARGER SPECIFICATIONS
Output of 5 volt DC; negative polarity; 200 milliamperes current
capability; plug tip outer diameter of 3.4 millimeter, inner diameter of
1.3 millimeter.
To power the FR300 with an AC adaptor/charger, plug it in and set
the power selector switch to the BATTERY position.
IMPORTANT NOTE: If using an AC adaptor rated higher than
200 milliamps, unplug the internal rechargeable battery to avoid
damaging it.
