Model 201
Telephone Line Checker
The 201 detects digital/analog phone lines
before a modem is connected, thereby protect-
ing an analog modem from damage caused by
a digital line. Just insert the phone line into the
201 or plug the 201 with attached adapter cable to
the wall jack, then you may easily identify if the line is
safe by checking polarity and line current. The 201 has a line noise filter
to block radio frequency interference (RFI) that can corrupt data received
over modems and interrupt internet and e-mail connections. With the
201, the modem on your notebook computer will be completely protect-
ed and can reduce the headache of Internet, E-mail, and fax interruptions
caused by RFI.
■ Quickly checks if the phone line is digital or analog,
protecting your modem from damages
■ Detects over currents
■ Identify safe line, polarity, or open line
■ Line noise filter protection from RFI
■ Easy operation
■ Compact design for portability
