  If you're having trouble pairing your cellular phone to the Panasonic Cordless Telephone base unit, there could be several reasons: * First, confirm that your cellular phone supports the hands-free profile (HFP) specification, as compatibility issues may arise. * Second, ensure that the Bluetooth feature on your cellular phone is turned on. * Third, if the Bluetooth technology on your cellular phone is not functioning correctly, try turning your cellular phone off and then on again. * Fourth, if your cellular phone is already connected to another Bluetooth device, such as a Bluetooth headset, disconnect it. * Fifth, some cellular phones may require you to enter the Bluetooth PIN for pairing; confirm that you have entered the correct PIN.

  If you cannot hear a dial tone on your Panasonic Cordless Telephone, check that the base unit’s AC adapter and telephone line cord are properly connected. If the connections are correct, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, contact service personnel to have the unit repaired. If the working telephone does not operate properly, contact your phone service provider.
