Wall-mount installation (optional)
4. Install telephone base on wall jack
Hold the base up next to the wall jack, and plug in the line
cord. Then, push the base against the wall jack and down
until it is held securely by the mounting studs.
NOTE: If you cannot fit the base onto the wall jack,
remove the four non-slip pads.
5. Connect handset to base
Plug one end of the coiled handset cord into the
handset, and the other end into the base. Then,
hang up.
6. Set dial mode switch
This product comes set in tone dialing (TT) mode. Make
sure you choose the correct dialing method (TT or DP);
touch tone dialing will not work if you have dial pulse
service.
7. Check for dial tone
Lift the handset and listen for dial tone. When there
is an incoming call, the visual ringer indicator light on
the handset flashes.
If you cannot hear a dial tone, refer to the
Troubleshooting section (Page 15) and try to
correct the problem.
To disconnect the telephone, squeeze the clip on the
modular plug and pull it out of the jack.
