American Red Cross FR300 OWNER’S MANUAL

USING AN AC ADAPTER (not included)
Once plugged in, the AC adapter acts as a charger, charging the
internal Ni-MH battery pack. Charge it for 8 hours to achieve a
full charge.
1. Plug the adapter into the DC 4.5 V socket. If the socket for
the AC adapter on the case of the radio is labeled 5, ignore
this; it should be 4.5V.
2. For power, set the BATTERY/DYNAMO-ADAPTER/OFF switch to
the DYNAMO-ADAPTER position.
Only use an AC adapter of 4.5 VDC, negative polarity and
100mA current capability. To order the correct AC adapter call the
toll free number shown at the beginning of this manual, ask for
the parts department and order part # GPU3504.
EMERGENCY OPERATIONS WITH NO
POWER SOURCE
1. Set BATTERY/DYNAMO-ADAPTER/OFF switch to DYNAMO/
ADAPTOR.
2. While continually turning the dynamo crank, the radio, lights
and siren functions will work.
CELL PHONE CRANK CHARGING
Because cell phone batteries vary in their current ratings, we
cannot specify charging rates or usage time. 10 to 15 minutes of
cranking may result in 1 or more minutes of talk-time.
1. Set BATTERY/DYNAMO-ADAPTER/OFF switch to OFF position.
