Radio, Multiband, Solar, Wind-up
Radio, Multiband, Solar, Wind-up (Product Code: SLE/CS/06) is a portable AM/FM/SW1/SW2 radio that runs from a rechargeable NiMH battery charged either by its built-in winding handle or by a detachable solar panel, so it keeps working where mains power or dry cells are hard to get. Schools, learning centres and field programmes use it to receive educational broadcasts, news and announcements. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its educational science equipments and classroom supply range.

Typical Use
In classrooms without reliable electricity, a teacher can tune to a scheduled educational programme on FM, MW or shortwave and play it to the whole group through the mono speaker. The solar panel’s long lead means it can sit in direct sun outside a window or on a roof edge while the class listens indoors or in shade, and a minute of winding gives at least half an hour of listening when the sun is not available. The same radio serves community centres and relief sites for news, weather and public announcements.
The radio is also a handy teaching object: students can see solar and muscle energy converted to electrical energy, stored in a battery and turned into sound, which ties in well with a solar energy science kit in India’s upper-primary and middle-school science lessons. Fold the winding arm back into the body after use, keep the panel clean and free of scratches, and store the set in a dry place between sessions.

Frequently Asked Questions
Which frequencies does it receive?
FM 88-108 MHz, MW 520-1700 kHz, SW1 3-10 MHz and SW2 10-18 MHz, selected with a band switch.
How is the battery charged?
The 1800 mAh NiMH battery is charged by turning the built-in winding handle in either direction or by connecting the detachable solar panel.
How long will it play after winding?
Winding for 60 seconds gives no less than 30 minutes of listening at a set volume level; higher volume shortens this.
Can the solar panel stay outside while we listen indoors?
Yes. The panel has a lead of approx. 2.5 m, so it can be placed in the sun while listeners stay indoors or in shade.
How rugged is it?
It has a thick, robust plastic casing designed to survive a one-metre drop onto a hard surface, and the winding arm folds into the body for protection.
What documentation and warranty come with it?
Illustrated instructions in English are supplied. Warranty terms are confirmed in the quotation; ask us through the contact page.
