3 U SING THE M ODEM
Follow the steps below to use the modem properly.
To use the modem:
1 Check that the computer with which you are using the
V284+C modem contains a working Ethernet network card,
and has the following software installed and operational:
•Microsoft Windows 95 operating system or later
•Access to the Internet
•A standard Internet browser application
•The Telnet communications utility
2 Attach your computer to the modem’s LAN port with the
included RJ-45 Ethernet cable.
3 Connect the antenna cable to the CABLE connector on the
rear of the modem.
4 Plug the 9-Volt modem power supply jack into the POWER
socket on the rear of the modem, and plug the power
supply transformer unit into a standard electrical wall outlet.
Note: As with any household electrical device, avoid the risk of accidental
electrical shock. Make sure that your hands are completely dry and that there is
no moisture on the floor or other surfaces in the immediate area of the electrical
wall outlet.
After connecting the power adapter to the modem, verify that
the three green front panel LEDs light up for approximately 2
seconds before going out.
The orange POWER LED at the left of the front panel lights
up and remains lit, indicating that the modem is powered up.
Hazard: As with any mobile transmitting equipment, avoid of getting the human
body closer than 20 Cm to the modem or the antenna.

5 P ROBLEM T ROUBLESHOOTING
If you encounter problems with your modem, try the following
steps.
1 Check for damage to the external modem casing during
shipping or installation. If you see visible damage, the
modem may need replacement.
2 Verify that the 9-Volt modem power supply jack is
connected to the modem POWER connector on the rear of
the modem, and that the modem power supply is
connected to a known-good AC power outlet.
3 Verify that the RF coaxial cable is connected properly to
the modem CABLE connector.
4 Verify that the modem LAN LED is illuminated and that the
LAN cable is connected to a working Ethernet network port
on the PC.
Following are further steps you can take to identify and
correct modem problems.
# Problem Description Possible Cause Potential
Resolutions
1 The LEDs do not light
up. •The DC plug
may not be
installed
correctly.
