Denso BHT-400B-CE - Manual (Page 130)

[4.6] Key entry and vibrator test
Selecting "6:KEY VIBRATION" on the Hard 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 letters in the positions
pre-assigned to those keys on the LCD. Pressing the same key again
erases the displayed letter.
The table below shows the relationship between the keys and the identifier letters to be displayed on the
LCD.
