The power light on the modem is
not on.
Modem does not respond, modem
communication error or modem
not found.
Solution
•
Ensure the modem is plugged into your system’s USB
port. If your modem is plugged into a hub, it must be a
powered hub.
• If more than one USB port is available, try another port.
• Ensure “USB Support” is turned on in your system’s BIOS.
• Ensure the drivers are loaded correctly.
• Contact your computer’s manufacture.
• Did you select the correct modem type? If the Viking
modem is not listed, try a Hayes compatible modem.
• Is the USB cable completely plugged into its port and are
all of the connections secure?
• Check your computer’s BIOS setup. You may need to dis-
able a built-in COM port to prevent conflict.
• Is your operating system set to the correct Com port and
IRQ? Please refer to chapter 4, “Technical Notes”for
detailed information.
• Check your computer for conflicting COM port settings.
• If the modem stops after the computer enters power-
saving mode, disabling this feature is recommended.
