1) Power

Unit

•

Do the AL (local analog loopback) test, feed some data into the modem
and check if they were returned.

•

Please make sure the interface is connected firmly; also check if the cable
is in good condition.

We suggest the individuals who hold a malfunctioned the TAINET Network Series
Modem would contact with your local representative or distributor of Tainet, or just
directly access our customer service department as soon as possible in order not to
cause catastrophe. You may find the contact address and phone number in the cover
sheet of this manual.

Once the TAINET Network Series Modem malfunctions, please check and record the
indicators at the moment then turn the power off. Consequently, make sure the IC's on
printed circuit board are firmly sited. Try to turn the power on again, if the trouble still
exists, please follow the procedures below.

•

Make sure you get a proper power source. If no indicator is lighted,
probably the problem is the power unit.

•

Check the power fuse; if it is broken, replace it.
