Discontinued: This product is no longer available.
The TelCheck PRO not only detects dangerous telephone line conditions before a modem is connected, thereby protecting the modem from damage, but also features a line noise filter. Near a radio transmitter telephone wires can act as antennas which draw radio frequency interference (RFI) to corrupt data receiving over modem and interrupt your internet and E-mail connection. With TelCheck PRO the modem on your notebook computer will be completely protected and reduced the headache of internet/E-mail/Fax being interrupted by RFI. Compact and easy operation.
