How Can I Disable the 'New Voice Mail. Press VM' Notification on My Panasonic KX-TGD223?

On most Panasonic phones, particularly the KX-TGD223 model, the voicemail indicator can sometimes light up even when there are no new messages. To address this issue, you can try a couple of steps. First, if the handset still indicates there are new messages, press and hold the `#` key until the handset beeps. Then, on the base unit, press and hold the FIND/LOCATOR button (which is `#3` on the picture) for about five seconds. You might hear the handsets connected to the base start to beep, but keep holding the button for the full five seconds. After a beep, the message alert tone should reset. It's also important to ensure that the answering system is turned off. You can do this by pressing the ANSWER ON/OFF button, which is `#5` on the picture. If the problem persists, consider resetting the unit and deregistering the handsets. After resetting, you will need to set up and register the handsets again. To deregister a handset, start by pressing the `MENU` button on the handset. Navigate to “Initial setting” and then select “Registration.” From there, choose “Deregistration” and enter `3`, `3`, `5`. You can then select the handset(s) you want to deregister by pressing the corresponding handset number. Once selected, confirm by choosing “Yes.” After deregistering, remove the batteries from the handsets and unplug the base unit for about 20 minutes. Once that’s done, put the batteries back in and plug the base unit back in. To register a handset again, press the `MENU` button, select “Initial setting,” then “Registration,” and finally “HS Registration.” On the base unit, press and hold the LOCATOR button for about five seconds. Make sure to complete the registration process within 90 seconds by pressing `OK` on the handset when prompted. Once everything is set up again, check if the voicemail waiting alert still appears.
