INT: The LCD contrast may be adjusted (feature 27 in the diagram on page 16).
If no new alarm conditions exist, the LCD display scrolls through each connected SIM
channel in sequence. The LCD presents the current event/status screen for each channel
for about 4 seconds, then continues to the next available SIM channel number (and scrolls
back to the rst after the last channel).
If the TTDM detects a new Service, Fault, or Leak event, it immediately jumps the display
to the SIM channel affected, turns on the LCD back light, and pauses at that channel
number for several minutes.
NOTE: Use the left and right arrow keys to manually select the channel displayed.
