Does anyone have a user manual for a KX-T7880 cordless phone? We inherited a customer with a TD-816 that has one of these cordless gems on it that lost their manual and they need to turn the speaker volume down.

Thanks,
Kazz

That can be found at Panasonics web site

Thanks for the link. I couldn't see anything except ringer volume. I've listened to calls on this phone and some are very loud and hurt the ear to listen to.

Thanks again,
Kazz

Kazz, there are three levels for handset volume.
Low, middle and high.
During a conversation, use the up/down arrows on the side to adjust the volume, I believe it should stay there once adjusted.
