Question about Panasonic KX-T7731 Corded Phone
Iam using a panasonic kx-t7330 phone and suddenly i cannot use both intercom and phone calls. and the display is CO 1. somebody help me please.
I'm guessing the phone is 8 years old and you spilled something into the keystrip.
Start by unplugging it to see if it resets. Then, look for a mechanical failure (sticky buttons, broken buttons, etc.). Some alcohol and a Q-Tip will clean the buttons, or carefully take the phone apart and wash out the housing.
Last, but not least, any of the new 7730/31/35/36 phones will replace that set.
