Suddenly line 2 only works on wired phones

Line 2 stays lit on the base unit but not on hardwired phones.  I can answer and call on that line from hardwired but not from the wireless phones.  (line 1 works in all aspects on all phones) I tried to reset the answer line to auto and to line 1 but to no avail, line 2 stays lit on the base

    I have had the system for 4 years, it just happened.  Perhaps it was after a power outage.

    Did you just buy and install this or did this just happen?

Here are a couple of things to try. First is to disconnect the base and install a regular two line phone to verify that line 2 is ok at that jack. Also on Panasonics website, when you unboxed and installed that unit, there was a cord that had green plugs on it. That was a 4 conductor cord. If somebody changed that out to a 2 conductor, it could cause this. Also it could be a defective cord. If you have another 4 conducter cord from the wired phones, swap it out. Make sure on the base, on the back, that it is plugged in to the correct plug, marked line 1/2. Basically if a regular 2 line phone works, it is possible that the unit is defective. Also maybe unplugging the base from power and resetting that may fix it also.
If that does not help here is Panasonics number.

So much static I can not hear properly

The line that stays lit for line 2 is just the way it is.. not a problem. If you only have one phone line and a two line phone you will always have the one (non working line 2 ) lit.
Have you replaced the cord to the handset? Many times it is a bad cord that causes static.

How Does a Home Automation System Work?

Methods of Control

  • Components of a home automation system are controlled via various methods, depending on the manufacturer. Systems may be controlled wirelessly or may be hardwired. Wireless methods use radio frequencies like Bluetooth and infrared, while hardwired systems may use ethernet, phone cable, electrical wire or coax cable. Most systems use a mix of wired and wireless components.


  • Lighting is handled by inline dimmers, lamp plug-ins and gas fireplace dimmers. Hardwired dimmers and lamp plug-ins are installed between the light and the power source. The dimmers regulate the amount of power sent to the light giving you the ability to adjust the brightness of the lighting. Fire place dimmers work the same way, they allow you to regulate the amount of gas released and control the brightness and mood your fireplace gives off.

Heating and Cooling

  • Replacing your current thermostat with a "smart" thermostat allows you to remotely program when your air conditioning or heating unit operates and what temperatures they maintain. led displaystransparent led screenThermostats can either be programmed to switch on or off at certain times or may be controlled through the internet via an ethernet connection. You can also control it wirelessly via RF signals.


  • Security setups contain a base unit and any number of wireless and hardwired sensors for doors and windows. Sensors are made of two pieces that touch when the door or window is closed. But when the device is separated, by a door or window being opened, the electronic circuit is broken. The sensor reports the breach back to the base unit via radio frequencies. If the base unit is active when the breach occurs, it will sound an alarm and a phone line connection to dial pre-programmed contacts--such as emergency services or your cell phone.

Cameras, Surveillance and Driveway Reporters

  • If you have a driveway reporter, when something passes by and breaks its laser beam, alarm security systemthe length of the break and time of occurrence are reported back to a base unit inside your home via RF signals. Units detect the presence of people and vehicles but ignore animals. Cameras work similarly--they report video data back to a base unit via RF signals. Cameras may also use infrared technology for night vision or compacted circuitry for a smaller size. The base unit for the cameras sends video signals to a monitor, VCR or a hard drive.

Unplugged phone to put in new furn. plugged phone in and handset does not answer. It does respond to base.

Make sure the phone line at the base unit is plugged into the LINE position, otherwise you probably have a wiring issue.

I think this may be the answer. With multiple handsets reading "Please register" and a "working" base station (w ith dial tone). If you bring the remote units to the base station and place them on hte base, they will register and stay registered after you return them to the remote base. It doesn't say this anywhere in the instructions as it gives you the impression the remotes will register from their own base.
