2. Tests not requiring PC application
2-0. CN NAME LCD Display Test
After starting, at the same time as the check mode is activated,
the back light of all Mini LCDs lights up and the check pattern
appears.
As the check pattern changes at every pressing of any switch,
check visually that there is nothing abnormal.
The table below shows the contents to be checked for each
check pattern.
All dot lighting All dots should be turned on.
Frame lighting Outermost dots should light in the frame shape.
All dots turned off All dots should be turned off.
Numbers should be displayed in order from the
CH number display
left.
Variation in the NAME LCD test is acceptable. Variation means
that all dots turn on and off properly although there is variation in
the color depth. On the other hand, dots that do not change when
turned on and off are called black dots/white dots and unacceptable.
Also, check for reversed contrast as described below during the
normal operation check or sound output check.
While viewing the NAME DISPLAY at the height barely
visible from the front pad, adjust the contrast (close to the
maximum) so that the display looks deep black. If it doesn't
become deep black in that state but the NAME DISPLAY
viewed at the height barely visible from the opposite (rear)
side looks deep black, it is judged as NG because the angle of
visibility is reversed.
2-1. All LEDs Lighting Test
Press any 3 switches simultaneously in the CH NAME LCD
display check mode, and the All LEDs Lighting Test mode will
be activated.
Confi rm visually that all LEDs on the panel are turned on.
2-2. Respective Color LEDs Lighting Test
Press any 3 switches simultaneously in the All LEDs Lighting
Test mode, and the Respective Color LEDs Lighting Test mode
will be activated.
Every time any one switch is pressed, the lighting LEDs change
in the order of red, orange, yellow and green.
Check visually that there is no LED lit in any different color.
2-3. Switch Input Test
Press any 3 switches simultaneously in the Respective Color
LEDs Lighting Test mode, and the Switch Input Test mode will
be activated.
Have the LEDs corresponding to each switch lit in advance,
press and release the switch, and the corresponding LEDs
should turn off.
In the same way, check all the switches.
* Do not press 2 or more switches at the same time.
Confi rm visually if all the LEDs which were lit in advance have
been turned off.
For the switch without LED, have the nearby LEDs lit
correspondingly.

RECALL
There may be cases where DANTE is reset and switches fail to
follow (delayed in response).
This symptom is repeated every ten some seconds depending on
variation in the DANTE module. To eliminate such symptom,
enter the DANTE SETUP mode from the SETUP screen in the
normal mode, select REDUNDANT for SECONDARY PORT,
turn on the power again and enter the DIAG mode. Such
problem does not occur in the normal operation.

2-4. Encoder Input Test
Press any 3 switches simultaneously in the Switch Input Test
mode, and the Encoder Input Test mode will be activated.
Have the LEDs corresponding to each encoder lit in advance,
turn each encoder clockwise and counterclockwise one by one,
and the corresponding LED should turn off.
In the same way, check all the encoders.
Confi rm visually that all LEDs which were lit in advance have
been turned off.
For the encoder without LED, have the nearby LEDs lit
correspondingly.
* The LEDs made to correspond to the encoder in the
SELECTED CHANNEL section are the same as those in
Switch Input Test.
* The LEDs made to correspond to the encoder in the USER
DEFINED KNOBS section are the same as those in Switch
Input Test.
