Everything you ever wanted to know about the EyeMax
How long should the radio play for?
With a fully charged battery the radio will play for approximately 25 hours on normal volume. A 30-second wind at 120 rpm will provide about 30 minutes of play time (normal volume).
Do I need to do anything before I use it?
For best results, the battery requires a conditioning charge before first use, or after long periods without use. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by fully charging the battery using the wall adapter (if you have one). The product can, however, be used immediately in the wind-up mode if required.
How long will a fully charged battery retain its charge?
The battery will retain about 75% of its capacity after 1 month, 55% after 2 months, 40% after 3 months and 15% after 6 months.
Can I over-wind the unit - does it ever stop you from winding?
No, you cannot over-wind the internal mechanism. It consists of simple gearing which drives the alternator, providing power to the internal battery.
Will I damage the product if I crank the handle in the opposite direction?
No, the winder handle can be cranked in both directions.
Is the product waterproof?
No, it is not waterproof. It is splash proof and will work in rainy conditions.
How strong does the sun have to be for the radio to play directly from the solar panel?
The radio requires direct sunlight to operate solely off the solar panel. If the solar panel is placed in direct sunlight while the radio is switched off, solar energy will gradually charge the battery.
How long does it take to fully charge the battery?
Using an AC adapter, it will take about 24 hours to fully charge the battery. Or when the solar panel is in direct sunlight and the radio is turned off, it will take about 16 hours. Or using the crank, it will take about 40 minutes, if you constantly wind at the optimum speed as indicated by the green charge level indicator.
Can I leave it plugged in all the time?
Yes; the charging current is designed to be low enough to be non-damaging if left
on charge continuously. (Unplugging may extend the life of the battery, but note that repeated deep discharges will shorten it.)

The battery doesn't hold a charge any more; do I need to replace it?
Rechargeable batteries deteriorate over time, especially if drained nearly completely (to extend the life of your battery, limit how often that happens). However, in many cases they can be "conditioned" back to life. This can be done by administering several vigorous 30-second wind cycles. Alternatively this can be done by letting the product run from the battery until it stops, and then, with the product turned off, fully charging it using the wall adapter.
