The TelCheck PRO is an enhanced TelCheck. It does function not only containing telecommunications circuit that detects dangerous telephone line conditions before a modem is connected, thereby protecting the modem from damage, but also with the 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.
