My newly bought Dolphin NU touch 4GB has charged for over 6 hours. I fixed the headset correctly. Still it won't power on. Although when charging in the PC the screen lights up. Please help. Thx

The headset contains a lithium ion rechargeable battery, which should be charged before using the headset for the first time.

Notes

• If the headset is not used for a long time, the indicator (red) may not light up when you connect the micro-USB cable to charge the headset. In this case, do not disconnect the micro-USB cable from the headset and wait until the indicator (red) lights up.

• When you close the cover of the micro-USB port after charging the battery, push the catch at the edge (the round part) of the cover into the port compartment.

Tips

• If the micro-USB cable is connected to a computer while the headset is turned on, the headset will be turned off automatically.

• To charge the headset from an AC outlet, use USB Charging AC Power Adaptor* (sold separately). For details, refer to the manuals supplied with the USB Charging AC Power Adaptor.

• The headset cannot be turned on while charging the battery.

*Refer to the Reference Guide on the recommended adapter.
Caution
If the headset detects a problem while charging, the indicator (red) may turn off, although charging is not complete.
Check for the following causes:

• Ambient temperature exceeds the range of 5 °C - 35 °C (41 °F - 95 °F).

• There is a problem with the battery.

In this case, charge again within the above-mentioned temperature range. If the problem persists, consult your nearest Sony dealer.

Notes

• If the headset is not used for a long time, the battery may be quickly depleted, however, after a few recharges, the battery life will improve.

• Even if you do not intend to use the headset for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.

• If the headset is not used for a long time, it may take longer to charge the battery.

• If the life of the built-in rechargeable battery drops to half the normal length, the battery should be replaced. Consult your nearest Sony dealer for replacement of the rechargeable battery.

• Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave the headset in a car parked in the sun.

• If the computer enters into hibernation mode while connected to the headset, charging will not be completed properly. Check the setting of the computer before charging. The indicator (red) will go off automatically even if the computer enters into hibernation mode. Charge the headset again in this case.

• Use the supplied micro-USB cable only, and connect directly to a computer. Charging will not be completed properly by an indirect connection, such as via a USB hub.

Try performing a power reset. There should a power reset button near the charging port. It looks like a tiny hole. While plugged into the charger, use a paperclip to push the button inside this hole for 3-5 seconds. If it turns on, please allow it to charge for 4-6 hours before using it.
Support Troubleshooting Guide

Please follow the correct instructions below to successfully pair your headset with the phone.Make sure that the headset is sufficiently charged before pairing.

Charge the battery
Before using your headset, charge the battery for at least 8 hours. Charging the battery completely (and keeping it charged) will help you get the longest possible talk and standby time out of the battery.

Pair the headset to your Bluetooth phone
Pairing is like "introducing" two Bluetooth devices and giving them permission to connect to each other. If you want to use the headset with more than one phone, you need to pair it with each phone separately. Once a phone and the headset are paired, they can connect automatically whenever they detect each other.
1. Make sure the headset is powered off and the power adapter is not connected (you can't use the headset while it's charging).
2. Press and hold Power until the LED flashes alternating red and blue. The headset is in pairing mode and should be visible to other Bluetooth devices.
3. On your phone, start a search for Bluetooth headsets or handsfree devices. (This process may take several seconds, and it will be different for each phone; see your phone's manual for detailed instructions.)
4. Your phone should discover a device called a BT108, BT108 headset, BT109, or BT109 headset, When your phone asks if you want to pair with this device, answer yes.
5. When your phone prompts you for a PIN code or password to pair with the BT108 or BT109 enter 0000.
6. When the headset is paired, the LED turns blue and flashes every 3 seconds. Your phone might display a confirmation message, also.
7. Your phone might ask if you want to change the headset's name; generally, you should only change the name if you have more than one BT108 or BT109 headset that you use with this phone.
Connecting to your phone
Most phones connect to the headset as soon as you pair it; if yours won't, turn the headset off and back on. If headset still won't connect, check your phone's owner's manual for additional Bluetooth information.
Once the headset is paired:
Whenever you turn the headset on, it will automatically try to connect to whatever device it was connected to last.
If the headset loses the connection (e.g., if your phone is out of range), it reconnects automatically. To manually reconnect, press Power.
If the headset goes more than 1 hour with no connection, it automatically turns off.

send it back for a warranty refund as it is defective
you do anything and the warranty is void

Well maybe it doesn't speak dolphin, please be a little considerate

Well the problem is that the batteries are not connected correctly or the joystick is disconnected or something isn't right with the power supply(batteries). You should never charge the chair more than 18 hours. If it doesn't charge after that many hours there is a problem that continuous charging won't help. Since it is a new chair I would contact your provider where you bought the chair and have them come out to repair it. It is under warranty and its their responsibility to fix it I wouldn't let them get by with offering some lame excuse as to they're not able to fix. If all else fails contact Pride Mobility @ 1-800-800-8586 and tell them of your problem and demand repair.

did you ever get a solution?i do have the same problem!

I have the same problem! its brand new and charged it for 4 hours.. it still wont turn on. how did you fix it?
