I've never sold the 816 but looking through the manual,if you have call forwarding turned on at your set the according to the manual the spkr light will flicker.If that's the case the handset on hook dial #11 to cancel the all call forwarding
#12 to cancel call forward busy
Usually with an electronic telephone if you have a stuck button then none of the other buttons will work because of the way the keys are read by the microprocessor in the phone.
