[5.3] Key entry & beeper test
TEST KEY
Selecting "3: KEY" on the TEST menu calls up the
screen shown at left and makes the BHT-5000 ready
for entry from the keypad.
Pressing individual keys displays the identifier let-
ters in the positions preassigned to those keys on
the LCD and sounds the beeper. (As long as the
individual key is held down, the beeper continues
beeping.)
Pressing the same key again erases the displayed
letter.
The tables below show the relationship between
the keys, the identifier letters to be displayed on
the LCD, and the frequencies (Hz) of the beeper.
After all keys are pressed and displayed on the
LCD, this test automatically ends and the screen
returns to the TEST menu.
To stop this test in progress, turn the power off
and on.
