10 010 Output L Connect the level meter (with a JIS-C filter) to the [PHONES/OUTPUT] jack. (33Ω load)

Set the [MASTER VOLUME] at maximum and check the output level (1 kHz sine

wave, PAN=L).

PHONES L : -5.5 dBu ± 2 dB PHONES R : less than -45.0 dBu

18 018 SW Chk Checks the switches on the panel.

Press the switches on the LCD as instructed. A pre-assigned note is output when the

switch is pressed. A rotary encoder is clockwise set up to UP and is counterclockwise

set to DOWN. (See P.36 "Table 1".)

The check result appears on the LCD when all the switches are pressed as instructed.

Check that "SW OK" is displayed. Also, check that no key stick is existed.

(OK:"SW OK", NG:"SW NG", When multiple switches are pressed at the same

time:"Over Two")

19 019 All LED Chk Check that all the LEDs on the panel are on.

20 020 Red LED Chk Check that all the red LEDs on the panel are on.

21 021 Green LED Chk Check that all the green LEDs on the panel are on.

22 022 LCD On Check that all LCD dots are on. (The whole screen becomes white.)

23 023 LCD Off Check that all LCD dots are off. (The whole screen becomes blue.)
