What to do if even though following the manual instructions, none of the operations work when using a proprietary Panasonic telephone?

If none of the operations work when using a proprietary telephone, the Intercom line may not have been seized. The seized line, when going off-hook, may have been changed by personal setting. If the setting has been changed, press the INTERCOM button after going off-hook and follow the instructions.
