9.8 Initialization Information at Startup
Every time the display is powered up, the display will run through an initialization during
which it will test all LEDs and addresses. First, the message center will display the proper
address number. When completed, the initialization test will display Home and Guest in the
appropriate location. If the entire TNMC display fails at startup, signal may not be properly
connected, or the address plug may not be connected to the J17 jack on the TNMC controller
card. Check both connections in the event of a failure.
9.9 Replacement Parts List
The following table contains some of the TNMC components that may have to be replaced
