The main console runs on Ni-MH rechargeable batteries. So, if you’ve inserted alkaline or other types of battery, it’ll keep showing you this message.

There are many reasons for a not-working deskset. You’ve to check those parameters one by one and it’ll be solved.

Panasonic phone problem 8

We hear a noise and sound delay or interruption during a call.


This issue occurs when someone is using a computer connected to the same network as the main console. Remember that these phone systems require a minimum of 100 kbps and ask your network administrator to ensure that.

Panasonic phone problem 9

I can’t make a call and it’s important.


To make a call, you need to ensure that the STATUS indicator on the unit has a steady green light. When it’s red or the unit is downloading a software update, or the handset is too far from the base unit, you can’t make a call. Wait until the STATUS light is green or move closer to the unit to solve this issue.

Panasonic phone problem 10

The handset or the deskset is not ringing or we’re not hearing the tone.


For both cases, make sure that it’s not in the silent mode, the ringer isn’t turned off, call forward or do not disturb is activated, and your administrator hasn’t set it to block anonymous calls. Also, adjust the ringer volume and you’ll be good to go.

Panasonic phone problem 11

The voice of the caller is breaking up, what should I do?


This is another very common problem we face. It happens when your base station is exposed to high electrical interference. Relocate the unit and keep close to the base unit to solve this issue.

Panasonic phone problem 12

I don’t know how to remove the “Missed Call” sign from the display.


The message on the display goes away simply by viewing the list of missed calls.

Panasonic phone problem 13

What to do when liquid or some sort of moisture enters the base station?


The first thing you need to do in this situation is to unplug the AC power adapter. Also, disconnect the Ethernet cable.

Then, remove those rechargeable batteries. After that, leave the base set like that for at least 2 to 3 days based on how much liquid went inside. Give it more time if you feel that it’s not completely dry.

After the time has passed, put the batteries inside; connect the adapter, and the Ethernet line. Then, turn on the device. Hope it’ll work fine. But if you see that it isn’t working, contact your local phone dealer and get it repaired.

Remember, you must not use a microwave oven to speed up the drying process. 

How to set up a multi-line phone system properly

We’ve read the troubleshooting part but it’s true that prevention is better than cure. So, knowing the proper installation process can save you a lot of trouble. Let’s see the steps for the proper installation of the Panasonic multi-line phone system.

  • Firstly, contact your phone company to give them the number of your required line. They will take all necessary steps to make the lines available to the phone box outside your building.
  • Secondly, buy a phone cable to connect your phone system with the phone box. If you want to save money, you can carry 2 lines in one cable. Ask your professional installer to do it and you can use a decoupler if you need to separate the line later.
  • Thirdly, after finishing the connection process, tell your provider to set up a call rotation feature. What this feature does is that it simply forwards a call online to another line when the called line is busy.
  • Finally, connect your multi-line phone system’s main console to the line. Then, connect other desksets or handsets to the main console, set all the features and settings, and you’re ready to take business calls.
