ABOUT THE BUILT-IN RECHARGEABLE BATTERY
The built-in rechargeable battery is a nickel-metal-hydride (Ni-MH)
battery pack. It is charged by cranking the dynamo rapidly, about two
turns per second, resulting in up to 60 minutes of low volume radio
play when the battery is fresh. The battery pack is located in the bat-
tery compartment and can be replaced once it no longer holds a
charge. In North America, replacements can be purchased directly
from
etón Corporation. The generic specifications are: Ni-MH, 3.6 volt
DC, 600 mAh. The replacement’s voltage must be 3.6 volt DC, the
milliamp-hour rating may be larger or smaller, e.g. 200 mAh or 800
mAh and the polarity must match red-to-red and black-to black on
the plug-in cord. Since these are portable telephone batteries, they
are available at many retail stores.
USING DYNAMO POWER
Turning the dynamo crank charges the built-in Ni-MH battery pack.
It can be charged while the radio is playing or turned off, however it
does not charge as efficiently when charged while playing, thus
reducing playtime. With hand-crank dynamo charging, radio operation
time depends on the number of turns and time per turn. With a fresh
battery pack, 90 seconds of vigorous cranking, at about 2 turns per
second, results in up to 60 minutes of radio play at low volume,
without light use. If the light is on while playing the radio, radio play-
time is somewhat reduced.
1. Switch the power selector to the OFF position.
2. Turn the dynamo-crank vigorously either clockwise or counter-
clockwise.
3. To turn the radio on, switch the power selector switch to the center
DYNAMO/ADAPTOR position.
While charging, the red LED charging light will be on (top left of FR200).
