Any repair information is intended for professional repair shops only.
Users of Freeplay equipment should not attempt any repair which involves any disassembly. Some of our older products were driven by powerful springs which, if allowed to unwind in an uncontrolled manner, would be dangerous and could cause injury. Never remove covers from such devices.
Please note in all instances where the product is faulty and is under warranty, please return it to the retailer where purchased. We do not carry out any repairs.
My Mini Sherpa did not come supplied with a charger. What type of charger can I use to charge it?
The mini-USB type adapters are not sold with the products as many people may have these already for use with their mobile phones and digital cameras. Any mini-USB charger will do as long as the output conforms to the USB spec ie. 5V. The capacity (mA) is not critical. You can also charge the product via your computer's USB port using an inexpensive cable (USB-A to mini-B, 5-pin not 4-pin).
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 do I change the light bulb?
The light is an LED (light-emitting diode) with up to 100,000 hours of useful life and never requires replacement.
How long does it take to fully charge the battery?
Using an AC adapter, it will take about 4 hours to fully charge the battery. 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.
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.
How long should my Mini Sherpa shine for?
With a fully charged battery the Mini Sherpa will shine for approximately 11 hours. A 60-second wind will provide 20 min of shine time if the winder handle is cranked at the optimum speed. This will be achieved as soon as the green charge level indicator next to the winder handle illuminates.
Where can I find the instruction manual?
Download Mini Sherpa manual.
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 anymore; 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 followed by a full charge with the adapter. 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.
I tried to use the winding handle and it would only wind one way. Also, there seems to be no resistance when winding and the charging LED doesn't illuminate.
It sounds like a mechanical failure.
The on/off switch appears to have failed as with the batteries charged, switching the torch on, either normal or bright setting, produces a momentary flash only.
A brief flash in most cases is a sympton that the internal battery is faulty rather than a problem with the switch. However, a few times it can be a component problem on the PCB. Unfortunately, this is not reparable.
What is the specification of the battery?
It is a 3.6V 2/3 AAA 350mAh battery pack.
