About setting

Where on my forearm should I wear the device ?

With your palm facing up, locate on your forearm, the midpoint between your wrist and your elbow.
The UnlimitedHand should be set so that it’s center (Power Switch location) covers that point on your forearm.

Should I let my children try on the device ?

It is safe for children to try on the device, however make sure the child acknowledges what the device is
capable of in order to prevent accidents caused due to unsupervised use. For this reason it is best to keep the device
away from small babies or children who cannot manage to express themselves with words.

The circumference of my arm is too large/small for the device, what should I do ?

For those who have relatively lean forearms, try wearing the device closer to the elbow side of your forearm.
If the wear remains loose, we will provide you with a S-sized silicon pad as a replacement.
For those who have relatively thick forearms, try wearing the device closer to the wrist side of your forearm.
If the wear remains tight, we will provide you with a L-sized silicon pad as a replacement. Contact us at info@h2l.jp for replacements.

About connect about connect

The device is not recognizable by my PC and appears as unknown device.

It may be a problem with the USB connection, please try using another cable (with data transfer).

Is it possible to program the device through a USB connection rather than Bluetooth ?

Certainly, for developers who dislike being interrupted by broken connections,
USB development is the way to go. Be reminded to confirm that the correct port is selected.

Why can’t I establish a Bluetooth Connection ?

Confirm that your device is already paired with the computer. For details,
follow the instructions in this tutorial.
Be sure that you are within the device’s transmission range of 6 – 10m, and that the device is not already connected to an active USB port.

Can my device automatically pair itself with my game ?

Once the device is paired with your computer, the device will be recognized
as long as you are in the range of the computer’s Bluetooth transmission range.
You may add an handshake sequence into your game’s loading operations to make confirmations.

After using

My arm feels fatigued after a development session, is this normal ?

Temporary fatigue may be experienced due to consistent working of the
muscles by the device. Similar to a round of work out, your muscles require a short recovery period.
Avoid using the device until fatigue disperses. Please consult a Doctor if fatigue persists.

Will stimulation weaken as I move further away from the computer ?

No, as long as a working Serial Connection is established, distance makes no difference to the strength of electric stimulation.

About Devise

What is the maximum Bluetooth transmission range of the device ?

In an ideal environment, the device will have a 10m (33ft) range.
With obstructions counted in 6 – 8m (20 – 26ft) would be the approximated range.

How should I clean the silicon pad of my device ?

Never soak the device into water or clean it directly with water.
Use a dry towel to brush and rub off dirt and dust.
Persisting spots or stains, try using a towel slightly dampened with detergent.

What is the battery life of the device ?

When fully charged, the device will be able to operate for 1 full hour before it’s battery depletes.

How long does it take for the device to reach a full charge ?

When charging through a USB connection, the device takes around 1.5 hours to complete a full charge.

Can I get replacements for the blue gel pads ?

Yes you can, please access ourhome page for a list of purchasable accessories.
There will come a day when your gel pads loose their adhesiveness and cease to stick to your skin.
At this time, please consider replacing your gel pads to allow for optimum performance of the device.
