In the BHT-6500/BHT-7000/BHT-7500, specification of 0, 1, or 2 to
frequency
drives the beeper or vibrator depending upon the settings made on the "LCD con-
trast & beeper volume adjustment and the beeper & vibrator switching" screen.
If 0, 1, or 2 is set to
frequency (or if the frequency option is omitted), then
you can adjust the beeper volume on the LCD when powering on the BHT. (For
the adjustment procedure, refer to the BHT User’s Manual.)
In the BHT-7000/BHT-7500, you may change the beeper volume with the
OUT
statement. (For details, refer to Appendix D, "I/O Ports," D5.)
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.
• In the BHT-3000/BHT-6000/BHT-6500, specification of any of 3 through 61 to
frequency deactivates the beeper; in the BHT-4000/BHT-5000, any of 3
through 260 deactivates the beeper; in the BHT-7000/BHT-7500, any of 3 through
39 deactivates the beeper or vibrator.
• In the BHT-4000, specification of 5001 or greater to
frequency automatically
sets the frequency to 5000 Hz.
• Specification of zero to
onduration deactivates the beeper.
