• Cycle the status lights (Red, Orange, Green) indicating that the 7900HT
instrument is active (see “Reading the Instrument Status Lights” on page 2-5
for more information).
IMPORTANT! Do not power on the 7900HT instrument if you have removed the
lower-side panel of the instrument. Doing so prevents the instrument from uploading
the firmware from the computer and causes the software to display an error.
