A.5 Enable/Disable Tractor or Trailer Monitoring
In the event that only one vehicle is being monitored, Tire-Safeguard
allows the user to easily disable the Tractor or Trailer tire monitoring;
however the user cannot disable monitoring both vehicles.
• Press and hold down the Setup Button for 3 seconds, the system
enters the Setup Select Mode. Release the Setup Button. One of
the following screens shows up on the display.
Disable or Enable
Tractor TPMS:

(Use this mode only for
external sensors installed in
sorted ID sequence)
• Pressing the Control Button to call up the desired screen.
• Pressing the Setup Button on the Disable screen suppresses the
Tractor or Trailer tire monitoring; system exits setup mode.
• Pressing the Setup Button on the Enable screen restores the
Tractor or Trailer tire monitoring; system exits setup mode.
• The Trailer Auto-Setup procedure is similar to the Tractor
automatic setup procedure described above.
A.6 Auto-Setup Low / High Tire Pressure Warning Thresholds
After sensor installation the abnormal tire pressure warning thresholds
should be set up in accordance to the normal cold tire pressure of the
vehicle. The Monitor has an automatic Set Alarm (“SA”) mode to make
setting up the warning thresholds much simpler.
Version 1.2 User’s Manual 14
To enter the Set Alarm mode
from the Monitor, press the
Setup button (on top) for three
seconds, then the monitor will
show a screen with “SA” on it.
When in “SA” mode, press the Setup button once will trigger the monitor
to set up the warning thresholds for all axles according to the current tire
pressure, as follows:
• The low pressure warning threshold for an axle will be set to
12% below the average of all tires on that axle, e.g., a steering
axle with pressure of 80 PSI and 84 PSI for the two tires (i.e.,
average 82 PSI) will be set to having a LP warning threshold of 72
PSI.
• The high pressure warning threshold for the vehicle will be set
to 30% above the highest average pressure of all axles, e.g., a 3-
axle motorhome with average axle tire pressure of 80, 90, and 100
PSI, respectively, will be set to having a HP warning threshold of 130
PSI
After pressing the Setup button on the “SA” screen, the monitor will set
up the warning thresholds for all axles (provide that the tires have normal
pressure) and then exit to normal operation automatically.
Note: The user can always adjust the warning levels following the
instructions described earlier in the "Display Parameter Set Up" Section.
