TROUBLESHOOTING TIPS
How long should I initially charge the internal battery?
The display comes partially charged but you should charge the display, using the included
charging components (USB-C cord and 12v adapter), for 4-5 hours. See page 5
Why am I am having trouble seeing the screen to program it?
You must remove the protective screen cover before using the display. Locate the tab in the
upper right-hand corner of the screen protector and pull the protector off. See page 7
How does the display mount to the suction cup mount?
The new suction cup mount has a magnetic plate that afxes to the back of the display.
Simply mount the suction cup assembly where you want it and touch the back of the display
to its surface. See page 5
How can I change the brightness of the display?
The display has a photo eye that automatically regulates the display brightness. There is no
manual override for it. At night, the display dims. During daylight, the display brightens.
How do I know what tire pressure settings to use for my high- and low-pressure
alerts?
This display will automatically set up your alert parameters when you input the cold tire
pressure you are using for your tires. It will set the high alert to 25% above that pressure and
the low alert to 10% below that pressure. You can also set your high- and low-pressure alerts
manually if you prefer. See page 11
Normally, the tire icons rotate from one to another and show me individual
temperatures and pressures. How can I select one tire if I do not want to wait for
the tire icons to cycle through?
With this new touch screen, you can just tap on a tire position to instantly view temperature
and pressure for that tire. See page 9
Did I see this unit has a GPS component to it?
Yes. The GPS is not used for navigation, but it will tell you your direction of travel (compass),
current time, current date, your speed, trip distance and current altitude. Allow up to 15
minutes for the GPS to initialize the rst time. See page 7
Can this display alert me to low sensor battery voltage?
Yes. This display will show battery voltage levels in each sensor. Tap on the “Settings” icon
on the lower left on the home screen. On the next screen tap on the left or right arrows. Tap
on the “Sensor Battery Voltage” icon. On the next page, tap on the tire icon to see the sensor
battery voltage. See page 23
How long will the battery last in the display and can it be changed?
The battery in the display will last many years. It is designed to last the life of the display.
When the internal battery is exhausted, it cannot be replaced easily. See page 5
What is the small antenna icon for on the display screen.
The antenna (Repeater Signal) icon tells you that the repeater you installed is functioning
properly, (amplifying the signal from the tire sensors to the display). See page 5
