My message light on base and 2 other cordless phones flashes constantly. There is not beeping just flashing lights. Have read manual but cannot figure out how to get rid of this flashing. When there is a message it flashes and beeps (which is normal) When message is retrieved the beeping stops but flashing continues. Very annoying.

Press down the "find handset" button until the paging beep stops (about 5 seconds) and this will reset the indicator lights on the handsets.

Bit late now but I found mine was caused by the date and time on the handset resetting to the wrong year as I had unplugged it for a while so once I reset that all was ok

If the message light on your base unit and other cordless phones is constantly flashing, even when there are no new messages, it could be due to a few reasons. Here are some troubleshooting steps you can try:

1. Clear the voicemail: Sometimes, even if you have retrieved a voicemail, the message indicator light may continue to flash if the voicemail system itself hasn't registered the message as "read." Access your voicemail system and ensure that all messages, including saved or deleted ones, are cleared from the system.
2. Check for "saved" messages: Some phone systems have a feature that allows you to save or mark specific messages as important. These saved messages may continue to trigger the message indicator light to flash. Access your voicemail system and review if there are any saved messages. Delete or mark them as "read" to see if the flashing stops.
3. Reset the phone system: Try resetting your cordless phone system. Unplug the power cord from the base unit and all connected cordless phones. Leave them unplugged for a couple of minutes. Then, plug them back in and allow them to reconnect. This reset may help clear any temporary glitches causing the constant flashing.
4. Check the message waiting indicator settings: Some phone systems allow you to adjust the settings for the message waiting indicator light. Check the user manual or the settings menu on your phone system to see if there are any options to modify the behavior of the message indicator light. You may be able to disable the constant flashing through these settings.
5. Contact the manufacturer or service provider: If the issue persists after trying the above steps, it may be best to contact the manufacturer of your cordless phone system or your service provider for further assistance. They can provide specific troubleshooting steps or advise on any software updates or settings changes that may be necessary.
