C2G TelCheck Pro

Outside noise such as electromagnetic waves from various radio devices and instruments could decrease your modem/fax transmission speed and interrupt your internet or telephone connection. Our TelCheck Pro provides a sophisticated noise filter that reduces RFI interference to improve your line connection. It also has a surge protector to protect your modem/fax/telephone from dangerous accidental power surges. Plus, it was designed with a circuit that protects your connection from interruption by other telephone stations.

With its compact and easy operation, the Telcheck Pro quickly checks if the line is analog or digital signal, identifies line polarity, recognizes if the line is overcurrent, prevents your modem from being damaged by plugging into an incorrect telephone system, and identifies the connecting status of the line whether it is a new installed line or an existing line. With the TelCheck Pro, you can relax knowing that virtually nothing can come between you and the internet.
