Power off the CS1642A / CS1644A by removing the power jack.
Step 2
Invoke Firmware Upgrade Mode by holding down the Mode Selection push button on the front panel
(see Mode Selection Push button, page 9) and power on the CS1642A / CS1644A. The orange LEDs
ash together.
Step 3
Go through the rmware upgrade procedure again.
