[5.7] Key entry, beeper, and vibrator test
Selecting "7:KEY & VIBRATION" on the TEST menu
calls up the screen shown at left and makes the
BHT ready for entry from the keypad.
Pressing individual keys displays the identifier let-
ters in the positions pre-assigned to those keys on
the LCD as well as sounding the beeper or running
the vibrator. (As long as the individual key is held
down, the BHT continues beeping or vibrating.)
Pressing the same key again erases the displayed
letter.
The table below shows the relationship between the keys, the identifier letters to be
displayed on the LCD, and the frequencies (Hz) of the beeper.
(Note) Only when the M3 (left-hand trigger switch) or M4 key (right-hand trigger
switch) is pressed, the vibrator works.
