Volume in earpiece barely audible, even though it is on Max.

You can simply dial any number and press the Volume Up button to increase your hearing piece volume. If that doesn't work, you should go to a service point to replace your phone's earpiece.

Thank you...

Many times there is a volume switch on the actual handset itself. Most commonly on the left side of vtech devices. there are three different volume levels. By pressing up on the button you should be able to turn the volume up until it has an audible tone confirming volume change. Handset should ring with incoming call when audible tone is heard by pressing up on volume button.

Hello,

Make sure that you have your telephone line from the wall jack plugged into the port on the fax that says "LINE" and that your telephone is plugged into EXT.

All your cables and jacks seem like they are working since your phone gets a dial tone, the onyl thing could be that the wires are mixed or the modem on the fax is broken.

Thanks,

Pat
