If this does not help, try connecting a headset or using the speakerphone and making a call (or
doing anything else on the V660 that usually produces a noise). If you can hear the noise
through the headset’s earpiece or the speaker, there may be a hardware problem with the
inbuilt earpiece.
V The LCD screen keeps going blank.
Press any key.
• If the LCD screen lights up, the settings in the Start > Settings > More > Power
Management are set to turn the screen off too quickly. See Section 13.11 on page 119 for
how to change the settings.
• If the LCD screen doesn’t come back on, the V660 may be switching itself off due to a low
battery charge. See the troubleshooting section entitled “The V660 keeps shutting itself
down.” on page 151.
V I cannot beam information to or from other infrared devices.
Check that there are no obstructions between the infrared interfaces of the two devices, and
that the interfaces themselves are free of dirt.
• If you want the V660 to receive information from the other device, check that it is set to
receive (Receive incoming beams should be selected in the Start > Settings >
Connections > Beam screen).
• If you want the V660 to send information to the other device, the other device may need to
be set to receive incoming beams. Methods of doing this vary according to the device.
23.2 V660 Access and Login
V I am asked for a ‘device password’.
The V660 has been locked using the device lock. When this is on, the V660 locks
automatically if it is not used for a set time. Enter the password and press Done.
• If you know the password and want to turn the lock off or change its settings, see Section
13.9.1 on page 116.
• If you do not know the device password, there is no way for you to access the V660.
Contact your vendor.
