Flashing Speaker Light 4

[campyracr]

In doing some cable maintainence, I unplugged a users phone to move it's cable. Since reconnecting it, his speaker light flashes incessantly. All other phone functions are normal.

I tried several combinations of buttons, and the programming menu, to no avail.

Try this combination: Shift, Speaker, Shift.

BIS beat me to the punch. That will fix it. It is the way to enable the test pattern (ascending tones) on the speaker.

Thanks BIS/Super Tanker.
That solved it.
