How do I turn on bell on my dryer

I found on my Whirlpool duet dryer (no end-of-cycle button on this model) that if you turn on "wrinkle guard" the end-of-cycle alarm is turned off. The owners manual doesn't mention this fact at all.

From the Whirlpool user manual:
(OPTIONAL) Your dryer may have an End Of Cycle Signal. The
signal is helpful when drying items that should be removed
from the dryer as soon as it stops.
?
On some models, the End of Cycle Signal is fixed.
?
On other models, the End of Cycle signal is part of the
Start button and is selectable. Turn the PUSH TO START
button to ON or OFF. The signal will sound only if the
selector is set to On.
