Question about Philips CD4401B/37 Phone
The ringer on the Philips CD4402B/37 CAN be turned off by holding down the # key on the dial pad for about 3 seconds (see CD 440 Manual, page 8, Item "I"). And a little "canceled note" icon appears in the screen. To turn the ringer ON when it is off, do the same!
