Before charging, be sure to read about the correct
operating voltage in the operating manual of your end
device. No guarantee is provided for damages due to an
incorrect voltage selection.
Important information for use
1. Always fold out the hand crank fully.
2. In order to increase the life of the battery and the
mechanical parts, please note the following points:
a) Do not turn the crank for longer than 5 minutes
if the unit is charged, that is, functioning normally.
b) If the light becomes weaker or nothing can
be heard on the radio, this means that the battery is
no longer sufficiently charged. In this case, switch the
light and the radio off and turn on the crank for a while.
c) Please turn the crank as evenly as possible (charging
is best at approx. 2½ – 3 revolutions per
second). Avoid cranking too quickly and changing
the direction of turning abruptly. Cranking too
slowly may affect the charging efficiency of the
generator adversely and cranking too quickly may
damage the mechanism or the crank.
d) Where the unit is functioning correctly, please stop
turning the crank after a maximum of 30 minutes.
e) In order to extend the lifespan of the battery, operate
the crank when not using the device every month
for at least one minute in order to avoid a exhaustive
discharge. Turn the unit off (power switch in position
OFF) when not using it for a long time.
3. Avoid exposing the device to extremely high
temperatures, and protect it from shocks! Avoid
dropping it!
4. Do not clean the unit with corrosive or other harsh
cleaning agents or using rough fabrics.
5. Turn off the light and radio during the charging process,
in order to increase the efficiency of the generator. But
the power switch must be in the ON position.
6. The unit may become slightly warm on being charged.
This is normal and is no cause for concern.
