How to Reset a Philips Phone
Philips makes a cordless phone system, which consists of a base station that plugs into a power outlet and the telephone line, and cordless phone handsets that wirelessly connect to the base station. If you have a problem with the phone, such as a lack of dial tone, an unresponsive keypad, or your not being able to hear the person you are calling or her not being able to hear you, try resetting your phone.
Unplug the power cord from the phone's base station.
Remove one battery from each handset.
Put each battery back in to each handset.
Plug the power cord back into the base station. This resets your Philips phone.
