GETTING STARTED
SOLAR PANEL
This product uses two AAA rechargeable batteries which
should be charged via the solar panel. For the batteries’
rst charge, it is strongly advised to charge it for at least
12 hours.

EN

To charge the battery:
1. Detach solar panel by exerting downward pressure and
pulling at a 45° angle (approx.) away from main unit.
2. Insert 2 AAA rechargeable batteries in battery
compartment located at the back of the solar panel.
IMPORTANT Place ONLY NiMH type rechargeable
batteries in the solar panel battery compartment. Do not
charge non-rechargeable batteries.
3. Expose the solar panel directly to sunlight for
approximately 5-6 hours to charge the battery. The
(red) CHARGING LED on solar panel will light up
indicating there is sunlight and unit is charging.
TIP Press and hold TEST located at the back of the solar
panel. (Green) FULL LED indicates batteries have been fully
charged.
4. Align holes with protruding plastic. Push solar panel
towards main unit and snap into place.
5-6 hours of battery charging will normally provide power to
operate unit for 2 months.
When the rechargeable battery is nearly at or when solar
panel has been detached, the (green) LED indicator on the
main unit and will ash.
TIPS
• For best results when charging the battery, place the
solar panel directly with view to sunlight.
• Direct solar panel as follows:
Solar panel facing: if you reside in the:
North Southern Hemisphere
South Northern Hemisphere
• Do not scratch the solar panel’s surface or wipe it with
strong detergent.
• Do not expose the solar panel to rain, snow or
moisture.
• The duration of the rechargeable battery’s charging or
operating time is determined by either the intensity of
sunlight or the position of the solar panel towards the
sun.
• Do not overcharge the batteries.

3. Press RESET after each battery change.
NOTE When the rechargeable battery power is exhausted
or when the solar panel has been detached, the backlight
function will be disabled and the performance of the radio
controlled clock may be affected.
Power adaptor (not included)
The adaptor powers the unit and can also be used for
charging the rechargeable battery. When connected to the
main unit, will be displayed.
