TROUBLESHOOTING TIPS
To set up Tag Axle pressure, tap on “Pressure Alert Settings” then tap “PWR Unit” then tap
“Manual Input High- and Low-Pressure Alert”. From there, put in the High-Pressure PSI (25%
above cold tire pressure) and the Low-Pressure PSI (10% below cold tire pressure) in the area
marked Axle 3. That will correspond to your tag axle position on the screen. See page 13
When I turn the display on, I do not see any tire pressure or temperature
readings…What’s up?
The system takes from 3 to 8 minutes to acquire sensor readings. It is not immediate.
I have been at a rest stop for a while and now my display is blank, why?
The 770 Display has a motion detection feature and, if it does not detect motion for
approximately 10 minutes, the screen will enter the sleep mode to conserve the internal
battery. Any movement of the display will activate the screen. See page 9
I have two different trailers I pull, both with sensors. How can I hide the tire
icons for the trailer I am not pulling?
The display has a feature called “Auto-hide”. Drive away from the trailer that is not hooked
up to the towing vehicle and, in approximately 15 minutes, the trailer left behind will be made
invisible on the screen automatically. See page 9. You may also use the Connect/Disconnect
feature. See page 19
What does a “Fast Leak” warning mean?
The tire showing the alert is losing 2 PSI or greater in less than 1 minute. Find a safe place to
pull over and check the tire as soon as possible. See page 9
How do I look at tire information on a tire without waiting for the display to
scroll to that tire?
On the main screen, simply tap the tire you need information on. See page 9
Why are there dashed lines across the screen for one of my sensors?
Dashed lines mean the sensor signal is not getting from the sensor to the monitor. It could
possibly be caused by interference, a low or dead Display battery (see page 5) or a repeater
not functioning (see page 34), among other things. Sensor troubleshooting or battery
replacement may be needed (see page 31-33).
