4.5 Temperature Alarm
When the subsystem’s internal temperature exceeds 50°C, the
TEMP LED will flash and an audible warning will be heard (see
Figure 5.2 above for LED location). To reset the alarm and disable
the audible warning, press the Alarm Reset button.
In order to protect the system from damage resulting from over-
heating, it should be shut down immediately. Inspect the operating
environment for causes of the overheating condition. After the sys-
tem has cooled down sufficiently, power it up and be observant of
any future temperature alarm conditions.
