Clock updating procedure
Clock firmware updates are performed with a small updating dongle. The
dongle installs the new firmware onto the clock CPU and is removed once
the update is completed.
Note: Depending on your current clock firmware version, you may or
may not receive a clock updating dongle.
Note: The dongle checks to make sure it contains appropriate firmware
for the device being updated and will not install the update if it is
for the wrong device.

Note: You may want to write down your clock configuration settings
before proceeding, as the update process resets the clock to default
values.
To perform the update, disconnect the power cord from the clock. Remove
the acrylic cover (you may want to use cotton gloves or some similar
method to avoid getting fingerprints on the cover) and set it aside. Locate
the programming connector on the CPU board, labeled "ISP J4". Note that
if you have a GEN I CPU (labeled "CPU 1.0") with an RF-Link mezzanine
