Specifications

You may change the beeper volume with the
OUT statement. (For details, refer to
Appendix D, "I/O Ports.")
If you set a value other than 0, 1, and 2 to
frequency, the beeper volume is
automatically set to the maximum and not adjustable.
• Specification of any of 3 through 39 to
frequency deactivates the beeper or
vibrator.
• Specification of zero to
onduration deactivates the beeper.
• Specification of a value except for zero to onduration and specification of zero
to
offduration keep beeping.
• Specification of a value except for zero to onduration and offduration
and specification of zero to repetitioncount deactivate the beeper.
• For your reference, the relationship between the frequencies and the musical
scale is listed below.
• The
BEEP statement does not suspend execution of the subsequent statement
until the beeper completes sounding or vibrating. Instead, the execution of the
subsequent statement proceeds immediately.
If a second
BEEP statement is encountered while the BHT is still beeping or
vibrating by a first
BEEP, the first BEEP is cancelled and the new BEEP statement
executes.
• If low battery warning operation starts during beeping or vibrating programmed by
the
BEEP, then the warning operation overrides the programmed beeping or
vibrating. Upon completion of the warning operation, the beeper or vibrator
resumes working as programmed.
