Etokfoks Line Checker Phone Caller Display Set with Three Exterior Line Plugs On Off Receiving Line and Reply Controls for Dry Ventilated

Caller ID service must be activated with the local telephone office before the line checker can receive incoming call information, so the telephone line needs this service active before you rely on the display to show caller numbers

Install the telephone in a dry ventilated place without corrosive gas, then insert one end of the line into the access or other connection socket so the unit can be connected as described for normal telephone operation and caller information display

When the telephone rings with caller ID service open, the display shows the caller number, and the on/off button can be used to hang up after the call, providing the listed control for viewing incoming information and ending the connection

For general dialing, press the on/off control so the working indicator lights, wait for the dial tone, and then dial the number, following the stated sequence for placing a call with the line checker phone and its operating controls

If a busy tone is heard after dialing, use the receiving line button for automatic line receive, then use the reply button to resend the dialed number, providing the specified controls for handling the line and repeating the call

The machine is matched with three kinds of receiving exterior line plugs, allowing you to choose one according to your needs while connecting the telephone line and using the caller display, dialing, receiving line, and reply functions
