CHAPTER 23
Troubleshooting
This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories.
• Power, Hardware and LEDs
• V660 Access and Login
• Cellphone Calls and Messaging
• Wireless LAN, VoIP Calls and Internet Access
23.1 Power, Hardware and LEDs
V I cannot turn the V660 on.
• If you are using the USB cable or the mains adaptor, check the Operation LED (the red
light in the top right-hand corner of the V660). If it is not on, see the troubleshooting
section entitled “The Operation LED does not come on when I try to charge the V660.”.
If you are using battery power only (you do not have any cables connected to the V660):
• The contacts (the metal parts) on the battery or the V660 may be dirty or corroded. Clean
them.
1 Do not use liquid of any kind to clean the battery or the V660.
• The battery may be nearly or completely discharged (flat). Charge the battery using the
included charger or USB cable. If you have another battery with exactly the same
specifications, try using it instead.
If none of these things help, the battery may be faulty, or your V660 may have a hardware
problem. Contact your vendor.
V The V660 keeps shutting itself down.
