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

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 port at the back

of the modem.

4 Plug the 9-Volt modem power supply jack into the POWER

port at the back 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.

WARNING: To comply with FCC RF exposure compliance requirements, the

modem should be located in a distance of at least 20 cm from all persons during

normal operation. The antennas used for this product must be outdoor or

indoor, fixed mounted on permanent structures, providing a separation distance

of at least 20 cm from all persons during normal operation.
