cause tires to lose pressure. If a tire is close to its low-pressure level, an alert can be sounded
when pressure drops overnight due to cooler temperatures. Inflate to proper level in the morning.
If sensors have not been programmed to the monitor, or signals are not received by the monitor
after first installed the screen will display “
ns
P
” (see Figure 3-1).
1. If the sensors have been programmed to the monitor you will now need to install the
sensors onto the proper wheel positions on the vehicle.
The sensor should be tightened only by hand, not with a tool. Use a firm grip and
tighten the sensor. Check for leaks with a soapy solution. The monitor will begin
to receive and recognize the sensors, and it will display the wheel positions as they are
received on the screen.
2.
When all the sensors that have been programmed to the monitor are received and within
the baseline air pressure parameters, the display will show
all the wheel positions that were programmed, the word
“
on
” will be displayed, on the screen, and the green LED
light will come on (see Figure 3-2). You are now ready to
enjoy the safety and comfort of your new DORAN 360HD Tire Pressure Monitor System.
(Black box products don’t have the green light)
3. If any of the wheel positions are not within the baseline air pressures an alert will be issued
by the monitor and the air pressure reading will be shown for the affected tire position and
the monitor will show PRESSURE and whether it is a LOW or HIGH warning. The audible
alarm will be heard
(no audible alarm for black box product)
(see Section IV for further
details about alarms).
4. If the monitor continues to search for a sensor after 10 minutes it is possible that the
sensor may not be programmed properly. Higher radio frequency (RF) transmissions
travel mostly via straight lines and along line-of-sight pathways. The 360HD sensors are
required to accomplish the difficult task of transmitting a low power FCC approved signal
from the vehicles tires to the monitor. If a sensor fails to be recognized, move the monitor
slightly. The vehicle could be in what is known as a “Dead Zone”, this is where the signal
is not able to travel because of its surroundings (pole barn siding, metal fence, side of a
building). Moving the vehicle just a few feet can sometimes overcome this problem. The
sensor will need to be removed and re-installed to activate the sensor for it to report
