SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.
CAUTION Please heed the points listed below during servicing and inspection.
Heed the cautions! Inspect for safety after servicing!

HOW TO CHECK FIRMWARE VERSION?
(1) Press the Shift and FWD button at the same time, then connect HC1000S to PC with USB cord to check the light
buttons that represent Firmware version.
Firmware Version Leds (Ver X .YZ)
Z: 1(CUE1),2(CUE2),3(CUE3),4(CUE4),5(CUE5),
X: 1(Auto Loop), 2(IN), 3(OUT), 4(TAP) 6(Auto Loop),7(IN),8(OUT),9(TAP)
Y: 1(CUE1), 2(CUE2),3(CUE3),4(CUE4),5(CUE5)
The first release is "Ver 1.17".
(2) Press the Shift button to retrurn to Normal Mode.
FIRMWARE UPDATE
Use the procedure described below to update the firmware to a newer version.
(1) Press the BACK and FWD button at the same time, then connect DN-HC1000S to PC.
(2) DN-HC1000S will enter updating mode. CUE-1(A, B) will light to indicate "Update Ready."
(3) PC Operation System will pop-up a new hard disc, named DN-HC1000S.
(4) Copy updated file (EX: DN-HC1000S_v1.13.bin), and paste on "DN-HC1000S" hard disc.
(5) It will start updating. After updating successfully, DN-HC1000S will switch to Midi Controller automatically.
(6) Firmware updating State:
CUE-1(A, B): Update Ready
CUE-2(A, B): Update Data(0%)
CUE-3(A, B): Update Data(50%)
CUE-4(A, B): Update Data(100%)
CUE-5(A, B): Update Success (* If it doesn't light, it means "Updating Error")
ALL LED LIGHT UP
(1) Press the BACK and SHFT button at the same time, then connect DN-HC1000S to PC.
