To prepare for the Firmware Upgrade, do the following:
1. Turn off the CE680L / CE690L or CE680R / CE690R and unplug the
power adapter.
2. Push and hold the Operation Mode pushbutton on the CE680L / CE690L
or CE680R / CE690R front panel. This enables the Local/Remote Unit to
operate in Firmware Upgrade Mode when it is powered on again.
3. Plug in the power adapter and power on the CE680L / CE690L or CE680R
/ CE690R. Note that the LEDs start flashing.

CE680L / CE690L or CE680R / CE690R RS-232 port.
Note: The Serial RS-232 cable is not provided in the package.
