The Modem Won't Execute Your Commands
If your modem won't execute the commands you enter (but
responds with OK messages) and your TR (Terminal Ready)
light is off, your modem is not receiving a terminal ready signal.
You can have your computer send this signal (sometimes called
a DTR signal for "Data Terminal Ready") by using your soft¬
ware program or by installing a jumper cable. See your computer
dealer for obtaining the appropriate cable.
Software Probiems
If you experience trouble getting the modem online, it may be
that the software program you are using is faulty or that the disk
it is on is damaged or contains garbled data. If you are using a
backup copy of your program, try using another copy or the
original disk. If the problem persists, try switching the modem
and computer off for a few seconds, then on again. If this helps,
it may be that the program is defective. Contact the retailer who
sold you the program.
Preventive Maintenance
To ensure top performance from your modem, follow these
simple guidelines:
• Use only the power cord with adapter supplied with your
modem. Connecting the wrong power cord can cause irre¬
versible damage to the modem.
• Keep the modem dust free.
• Clean the outside of the modem with a soft, damp cloth
only. Do not use household cleansers or abrasives—they
may damage the modem's plastic housing.
• When you turn the modem off, wait at least two seconds
before you turn it on again. Otherwise, the modem may not
initialize properly.
• Keep your modem out of direct sunlight.
• Avoid exposing your modem to extreme temperature changes.
Operate the modem only at temperatures ranging from 41°F
to 95°F (5°C to 35°C). Store your modem only at tempera¬
tures ranging from -4°F to 140°F (~20°C to 60°C).
• For shipping and storing the modem, repack it in its
original factory packing materials.
• Never remove the plastic housing from your modem. The
modem has no user-repairable parts, and you can void your
modem's warranty and FCC registration by taking it apart.
