B4D
English – 10
5. Troubleshooting
If something is not functioning the way you have expected, you can run the
following tests to exclude a defect of the B4D:
5.1. Test of the operation elements
For this test switch off the device first and remove all cables from it except
for the power supply. Push and
hold
the button
V1/C1
while switching the
device on. The device then starts the operational elements test mode. Now
you can test each button of the device. With each push you toggle the LED
state of the according button.
The drawbars and rotary knobs can be tested as well. Each movement of a
drawbar or knob makes the LEDs of the upper button row indicating the
position of the according element. If you have a foot controller, you can
connect this now to test it as well. In this case the LED display does not go
higher than the
PRESET 8
button.
You finish the test mode by switching off the device.
5.2. Test of the interfaces
For this test switch off the device first and remove all cables from it except
for the power supply. Now connect the
MIDI OUT
and
MIDI IN
with each
other using a MIDI cable. Push and
hold
the button
V2/C2
while switching
the device on. The device then starts the interface test mode. The upper LEDs
of the mode buttons (
BANK - UPPER
) are blinking. If you now move a
drawbar, for example, its information is output via MIDI and immediately
received again due to the set up MIDI loop. If sent and received data
correspond, the lower LED on the button
UPPER
is switched on for a short
moment. If this is the case, the MIDI interface is OK.
The same test can also be executed for the LINK cable. Therefore remove the
MIDI cable and connect
LINK IN
and
LINK OUT
wiatch each other using the
LINK cable. The test procedure then is identical.
You finish the test mode by switching off the device.
