The operation panel test is selected by pressing the numeric key 7 from the faculty test menu.
In this test, check that the display, LED lamps and keys on the operation panel are operating correctly.
Display test
Pressing the B/W Start key from the operation panel menu, "H" is displayed 20 characters by 2 lines. The next time the B/W Start key is pressed, all the
LCD dots are displayed. Check for any LCD dots in the display that are not displayed.
LED lamp test
All the lamps on the operation panel light by pressing the B/W Start key after the display test. Check for any LED that does not blink during the test.
(However, the Energy Saver key does not go on at this time.)
Operation Key Test
The operation key test is selected with the B/W Start key after the LED lamp test is done. In this test, a character disappears when its operation key is
pressed. The list of characters and their operation keys is as follows. Check to make sure at this time that all characters properly disappear when their
operation keys are pressed.

The one-touch dial key test starts once all characters disappear in the operation key test.
The characters 0 to #, 0 to 6 corresponding to 01 to 19 are displayed, and a character disappears when its one-touch key is pressed. Check to make sure at
this time that all characters properly disappear when their one-touch keys are pressed.
