The [AUDIO on/off] soft-key allows setting the beeper on or off. The key toggles between an
[AUDIO off] soft-key and an [AUDIO on] soft-key. The present state of the beeper would be the
OPPOSITE of the function shown on the soft-key. If the beeper is currently on, the soft-key
shows ìAUDIO offî; i.e., your alternate choice.
