Using solar power
1. In order to recharge your solarDAB radio's batteries using solar power,
position the radio so that its integral solar panel receives direct sunlight.
The more sunlight that falls on the solar panel - the more electricity it
can generate to power the radio.
2. The solar charging level indicator
on the display should
be used as a positioning aid to achieve the greatest output from the
solar panel. It works on a bar system similar to the battery indicator.
3. If no bars or showing (or if the icon disappears completely) then there
is no useful light available.
4. If less than half the available bars are showing, then there is some
power from the solar panel which can supplement the batteries in
operating the radio. The radio may be used and the batteries will last
longer than if there was no solar assistance.
5. If more than half the available bars are showing then there is enough
sunlight for the panel to operate the radio and simultaneously provide
some charge to the battery pack.
6. If all of the bars are shown, then there is suffi cient power from the
solar panel to charge the battery and to power the radio at a moderate
volume.
7. While it is possible for the solar panel to power the radio in the absence
of the internal battery pack, the radio should not be used in this way.
It is strongly recommended that the battery pack is ALWAYS installed
when the radio is being used.
8. Keep the solar panel unobstructed and its protective lens free of dirt
and grease. This will ensure best performance with the available
sunlight.
9. The battery indicator
on the display gives an approximate
indication of the amount of charge in the batteries. Note that directly
after a period of charging, this battery indication may show more charge
is available than is actually present and so the indicator should only
be used as a rough guide.
NOTE: Best performance of the solar panel will be achieved when the sun
is directly overhead, and the sunlight is unobstructed by clouds, foliage,
curtains, and the like. In certain situations and poorer light conditions,
the solar panel may not be effective and should not be relied upon as the
primary energy source for standard usage. The solar panel is designed
as a supplementary energy source which under suitable light conditions
is able to contribute up to 100% of the radio's energy requirement.
The solar panel will only deliver power to the radio, or charge the batteries
under natural sunlight. It will not deliver charge in artifi cial light.
Do NOT attempt to charge the batteries by placing the solar panel directly
under any kind of sun-lamp. This will cause irreversible damage to the
radio and may damage the casing.
