REQ: chg
TYPE: whatever phone it is - 2008, 3902, 3903, etc...
TN: loop shelf card unit
easy change? yes
ITEM: key 19 NUL - will clear all programming from the key
or
ITEM: key 19 cfw - just don't enter a number and it should take the current number out but still leave the key as a call forward key
OR go to the phone and hit the check forward button (if it was forwarded, it should show the chk fwd button) and then delete the number in it.
The phone will keep the last number it was forwarded to on that key even after the forwarding has been canceled. Ordinarily this is fine - it makes it easier on you if you often forward your phone to the same number - but even though the number is there, unless forwarding has been activated, it shouldn't do anything.
Which is a long way of saying I am not sure what your actual problem is and under what conditions it happens and on what system you are using with what phones...The above will clear the key but I can't guarantee it will fix your problem.
