I. INTRODUCTION
The DORAN 360HD is a full-time wireless electronic tire pressure monitoring system designed
for heavy duty trucks to monitor and display tire pressures from 10 psi up to 188 psi. It is capable
of displaying current tire pressure on demand, whether moving or stationary. The 360HD is a
monitoring system and will not prevent tires from losing pressure or failing. However, low
pressure is the leading cause of premature tire failure and the 360HD can provide early notice
of potential problems and assist in maintaining proper pressurization in vehicle tires. The
360HD can be used on all pneumatic tires.
The 360HD consists of two basic components: tire sensors which screw onto the valve stems
of tires, and a monitor. Sensors transmit a coded RF signal and alert if pressure drops. The
monitor displays each tire’s pressure and an audible alert if tire pressures drop. During an alert,
the low pressure tire location is displayed on the monitor, the monitor will display “LOW
PRESSURE”, the current pressure reading for that tire flashes, and an audible alert sounds. The
system can alert at 2 levels: The first alert occurs when pressures drop more than 12.5%. A
second more urgent alert occurs if tire pressures drop more than 25%. As with many RF
products, signal interruption can occur and prevent a signal to reach the monitor. When used
properly, the DORAN 360HD will inform the driver of the tire pressures on the vehicle so the
operator has the opportunity to make any necessary adjustments to the air pressure before a
serious problem occurs.
Tires and valve stems should be inspected thoroughly prior to installation of the system to
ensure they are in good condition and inflated properly. It is not uncommon to find valve stems
that need replacing when installing the 360HD system. DORAN recommends that rubber valve
stems be replaced with brass or stainless steel stems. Some rubber stems have been found to
be inferior and could fail prematurely.
A visual inspection of tires on a regular basis is recommended. The 360HD does not
prevent low tire pressure, it alerts when tire pressures are low, allowing action to be taken.
A damaged Sensor or valve stem can cause pressure loss. Inspect regularly. If repeated
faults are observed, discontinue use of the system and contact DORAN Mfg. Toll Free 1-
866-816-7233.
The 360HD cannot prevent tire/wheel overload. Overloading any tire is extremely
dangerous and can cause the failure of any suspension component, not just tires! The only way
to detect overloading is to weigh the vehicle! A vehicle should never be operated if the weight
on any wheel is greater than the design specification! Even a correctly inflated tire can fail if
overloaded.
Tires can fail for other reasons besides low pressure or overloading. Always be on the alert
for any other tire problems as indicated by unusual noises, vibrations, uneven tread wear, or

bulges on the tire! If any of these symptoms occur, have the tires checked immediately by a
professional!
SYSTEM COMPONENTS
If you are missing any of these components, DO NOT proceed with the installation. Contact
the manufacturer for any missing or replacement parts.
GLOSSARY OF TERMS
Normal Mode: When the monitor is monitoring all programmed sensors and there are not
any faults, the monitor will display a green light and the display will show “on”.
Alert Mode: When the monitor has received a signal that is outside of the parameters of the
“Normal Operation” an alert will be displayed with icons describing the fault along with an
audible beeping sound. Pressing the Set or Program buttons can turn off the audible alarm.
Baseline Air Pressure: This is the pressure that is programmed into the monitor to identify
what the pressure is to be in each tire position. The monitor will calculate all alarms from this
setting. The baseline pressure should ALWAYS be set when tires are at ambient temperature.
Ambient Temperature: This is the temperature of the outside air. Tires can heat up
significantly which will change the pressure in a tire. If pressures in the tires are set when the
tire temperature is elevated, it can cause the monitor to give alerts because when the tires cool
the pressure will drop and sometimes this will fall 12.5% below the baseline pressure.

II. SETUP AND INSTALLATION
DORAN suggests that all users install a remote antenna to receive maximum performance
from the system
1. Installing the Monitor
The 360HD comes standard with the hook and loop mounting option. You can purchase the
option to place on the sun visor, attach to the windshield, fasten to the dash, attach it to the
pedestal mount, or use the hook and loop pads to fasten the monitor to a flat surface. If you are
using the hook and loop pads, we suggest that the surfaces that you are applying the pads to be
cleaned with alcohol to remove any grease or oils that
could be present. Choose the monitor back panel
which will work best for your mounting application.
Then remove the appropriate small breakaway tab to
allow the cord to exit in the best direction. (see Figure
1-1).
In order to access the full benefits of the system, you will need to hard wire the monitor to the
vehicle’s electrical system. You will see that there are three wires in the harness. Red is the
12/24-volt positive constant connection. This should be connected to a 12/24-volt power source
that is always “on”. The Blue wire will be the “switched” 12/24-volt positive connection. This wire
should only be live when the key is in the “ON” position. The BLACK wire is to be connected to
a good ground. This hookup will allow the monitor to receive signals when the vehicle is not
running, and update the monitor in real time. When the key is turned on you will have the current
information for your tire condition immediately before you begin your next trip.
The monitor is fused internally, however some installers would still prefer to install an
inline fuse for precautions. We suggest an optional 2-amp fast blow fuse be used for this
purpose.
The first time the monitor is powered up the display will show “
ns P”. This is saying that there
are “No Sensors Programmed” to the monitor. It could be that the sensors that were programmed
to the monitor have not reported into the monitor in order to lock the sensors into the memory. If
this is the case it could take up to 8 minutes for this to happen. If this is the first time you have
attempted to install the system and the sensors have not been programmed into the monitor, the
system will need to be programmed per the following section.

2. Programming the Monitor
For monitor to function effortlessly, the user must install the correct data. The information input
to the monitor will allow the monitor to recognize the sensors and wheel positions as well as the
baseline pressures for all tires. This is done in the following steps.
Do not install sensors until all programming is completed and you have returned to the normal
operation mode.
A. Programming the Sensor location
1) Be sure that the power is on. The first time the monitor is switched on the display
should show “nSP”. This will signify that no sensor is programmed, or the monitor
has not received a new sensor signal yet. If this is the case it could take up to 8
minutes for the sensor to report in if it is already attached to the valve stem. You will
now need to enter into the programming mode if you need to add sensors to the
monitor. If you are entering new sensors into the monitor be sure to leave the sensors
off the valve stems until the programming is completed.
2) Press and hold the PROG button for approximately 5
seconds. The monitor screen will automatically
change over to the program mode, and then you can
release the button. When you have entered this
mode the monitor will display all of the tire positions
and the word “PROGRAM” will be displayed (see Figure 2-1). As you will see by
“PROG” is used to enter the program
modes. Also used to silence alarms.
“SET” is used to lock in selections
during programming. Used to turn
on and off the backlight.
(4) Arrow buttons are used to
navigate the screen and select
values in the program mode

Figure 2-1, the monitor can be set up to display a motor home pulling a car or trailer,
or a car / truck pulling a trailer.
3) Select a tire position using the arrow buttons and input the 3-digit serial number
located on the sensor into the monitor (see Figure 2-2 for the three-
digit number). The monitor will automatically capture the serial
number and information when air pressure is supplied to the sensor
for that wheel position and lock it into the monitor. Be sure to identify
sensors to their programmed positions. The sensors will identify the
programmed location and be identified for future reference. Use the
diagram in Figure 2-3 to record the 3 digit numbers for the wheel locations that you
will be selecting.
4) Using the arrow keys select the first tire position that you want to program. The
selected wheel location will be solid. The other wheel positions will only be an outline.
If sensors have already been programmed to the monitor, the only sensor locations
that will be displayed will be the ones that do not have a sensor already programmed
to it. When you have selected the position that you
want to program a sensor to, press the S button for 3
seconds. This will cause the first dash (see Figure 2-
4) of a three-digit sensor number to blink that will need
to be entered.

5) Using the up and down arrow buttons, change the first
digit to the first corresponding digit of the sensor ID
number that you want to program. When you have
selected the correct digit press the right arrow button
to move to the next digit in the display.
6) The center dash (-) of this digit will now blink (see Figure 2-5). Use the up and down
button to change this digit to the number needed for the second digit of the sensor.
When you have selected the correct number for the
center section of this number press the right arrow
button so the remaining dash (-) begins to flash of the
three-digit number (see Figure 2-6).
7) Adjust this position with the up and down button until
you have the correct number displayed. Pressing the
right or left arrow button will allow you to change one of
the numbers that you have previously selected if
needed.
8) If you have the correct number displayed, press the S button for 3 seconds until the
number flashes twice and you hear a beep twice to signify that the sensor ID number
was successfully input to the monitor (see Figure 2-6a).
9) A new position will be highlighted to input another serial number. If you wish to
program another sensor repeat the above steps 4 through 8 in Section A.
10) Once you have completed the sensor programming sequence for all tires, press the
P button momentarily to move to the next step. This will be the Baseline Pressure
Programming. The monitor will display as shown in Figure 2-7. If you are completely
done with all of the programming operations you can press the P button for 5 seconds
and the monitor will return to the normal mode of operation. This can be done at the
end of any section of the program mode when the programming is completed.

this mode (see Figure 2-7 for screen display).
NOTE: to skip this section and go directly to the Programming the Date and Time for
Stored Alarm History Information just press the P button briefly 1 time. The display should
look like Figure 2-10. Anytime during this mode you can escape out to the next program
mode by pressing the P momentarily.
The baseline pressure has been set in the factory at 100-psi for all wheel positions.
We recommend that you set the baseline pressure at the same pressure as your
recommended Manufacturers’ Operating Tire Pressures for each vehicle’s tire being
monitored. If you want to change the baseline pressure, or a new sensor is programmed,
then follow the procedure below.
The monitor should now be displaying the wheel positions available to program, the words
PRESSURE, the unit of measure (PSI, Bar, or kPa) and PROGRAM will be displayed as
well as the baseline pressure for the selected wheel
position (see Figure 2-7). The positions that already have
sensors programmed to the monitor will be highlighted at
this time (see Figure 2-8). You can program the air
pressure from 10 PSI to 188 PSI, depending on your
needs. Each wheel position can be set with a different
baseline air pressure if this is what is needed. The monitor
has been pre-programmed for 100 PSI at each wheel
position. If this is the baseline air pressure that you need
then you will not have to do anything in this mode and can press the P button and go to
the next step. If you need to change the baseline air pressure for a wheel position,
continue with steps 1-4 below:
1) Using the same procedure as done previously, use the arrow buttons to select a
wheel position and press the S button for 3 seconds. This will cause the first dash or
number to blink (see Figure 2-9) of a three-digit baseline pressure number that will
need to be entered for the tire position selected.
2) The first digit of the three dashes will automatically start to flash. To adjust the air
pressure for the first digit press the up or down arrow button to change the number.
For a number less that 100 you will need to start your number with a 0. For air
pressure of 95 PSI, the number for the baseline pressure would be entered as “095”.

3) Press the left or right arrow button to select the next digit. Use the up and down arrow
buttons to change that digit. When you have entered the number that you want, press
the S button for 3 seconds until the number flashes twice and a double beep is heard
to signify that the number has been locked into the monitor’s memory.
After enter the number that you want, to press Sand Psimultaneously for 3
seconds will set the number as the baseline pressure for all the tires in the monitor.
4) A new position will be highlighted to input a baseline air pressure. If you wish to
program another sensor repeat the steps 1 thru 3. If you have completed the sensor
baseline air pressure programming sequence then you can press the P button
momentarily to move to the Time and Date setting mode. If you are done with the
programming operation you can press the P button for 5 seconds and the monitor will
automatically return to the normal mode of operation. This can be done in any section
of the program mode when the programming is completed.

so you will be able to verify that this is the correct serial number to delete (see Figure
2-21).
2) When you have selected the location press and hold
the S button for three seconds. The three-digit
number will flash twice and the beeper will beep twice
to confirm that this position has been deleted. A
different position will be displayed and the tire
location that was deleted will now be gone (see
Figure 2-22).
3) If you have additional sensors that need to be deleted repeat the above steps until all
required sensors are deleted. If you need to program deleted sensors to a different
location, or add new sensors to the monitor’s memory simply press the P button twice
to enter into the Programming Sensor Location mode (see page 6).
4) When you are finished press the P button to enter into the HIGH PRESSURE
program mode, which is the last item to program. If you are done with the
programming operation you can press the P button for 5 seconds and the monitor will
return to the normal mode of operation. This can be done in any section of the
program mode when the programming is completed.
F. High Pressure Alarm Programming
NOTE: To enter directly into this program mode you will
need to press the Pbutton for 5 seconds until the
“PROGRAM” is displayed. Then press the Pbutton again
briefly 5 times to enter this mode (see Figure 2-23 for
screen display).
NOTE: To exit this mode press the P button for 5 seconds to return to normal operation
mode.
The HIGH PRESSURE PROGRAM mode will allow you to set up your monitor to alarm if
a pressure that is 25% higher than the baseline pressure is detected. This feature can

of the screen will display “
on or OFF” (see Figure 2-23 and 2-24). To turn on or off this
feature do the following:
1. Using the left and right arrow buttons you will be able to
turn this feature on and off as it is shown in the center
of the display.
2. When your selection has been made, the S button will need to be pressed for three
seconds to lock the selection into the memory of the monitor.
3. Pressing the P button briefly will rotate you back through the different programming
modes. If you are done with the programming operation you can press the P button
for 5 seconds and the monitor will automatically return to the normal operation mode.
This can be done in any section of the program mode when the programming is
completed.
III. INSTALLING THE SENSORS ON THE VEHICLE.
The monitor should now be turned on and it should be in the normal operation mode.
It could take up to eight (8) minutes for the monitor to receive the updated signal from
the sensors once the monitor has been activated if the monitor was powered down.
Be sure to inspect and replace any defective or cracked valve stems before installing the
sensors. If replacements are necessary we suggest replacing the valve stems with
a brass or stainless steel stem. It does improve the life of the stem due to premature failure from
drying out and cracking. Inferior stems have been found in the market and can cause extensive
damage.
Keep in mind that tire pressures will increase as you drive. When
tires are in motion, the sidewalls are under stress carrying the
load of the vehicle. This energy created by the tires develops
heat, which causes the air in the tires to expand. This can cause
air pressure to increase as much as 10 psi in certain applications. This is normal, and the
manufacturers’ recommended cold running pressures have already taken this into consideration.
Always adjust air pressure when tires are cold or ambient to the baseline pressures that were
programmed into the monitor for each wheel position. Cool temperatures and high altitudes can

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

quickly to the monitor. If you are using an optional remote antenna or signal booster kit,
reposition the antenna/booster for a possible better reception.
IV. ALARM MODES
NOTE: An alert indicates that you are operating your vehicle in a dangerous
condition. When the low pressure light illuminates, STOP and check your
tire(s) as soon as safely possible, and inflate them to the proper pressure.
NOTE: The DORAN
360HD will illuminate a flashing low tire pressure warning light
and an audible alarm when the inflation pressure in one or both tires is equal
to or less than 12.5 % below the programmed baseline air pressure. The
warning will continue to illuminate as long as the malfunction exists,
whenever the monitor is switched on.
NOTE: Audible alarm and green LED light are not available on all black box
products.
The DORAN 360HD has six types of alarm modes. The warning levels are:
 12.5% below the programmed baseline air pressure for the first low-level alarm.
 The next alarm level is 25% below the programmed baseline air pressure.
 There is also a FAST LEAK warning when 4.5 PSI is lost from the tire in less than 16
seconds.
 The optional HIGH PRESSURE warning can be selected when you program the
monitor. This alarm will react when the air pressure increases 25% above the
programmed baseline air pressure.
 A LOST SIGNAL alarm when the monitor does not receive the RF signal from a sensor.
 The HOT warning signifies that the sensor is reading a temperature above 175℉ (80
℃) around the sensor and could be signaling a suspension / wheel component
malfunction for that wheel position.

1. FIRST STAGE ALARM FOR 12.5% LOW AIR PRESSURE
On a first level low pressure alarm the monitor will alarm
at 12.5% below the programmed base line air pressure.
When this happens the backlight on the monitor screen
will light up. The green led light will go out, the Red
warning light will begin to flash. The audible beeper will
cycle at 1 flash or beep per second, the alarmed wheel
position will be displayed. The pressure of the low tire,
and the words LOW PRESSURE will be displayed on the
monitor (see Figure 4-1). The audible alarm can be silenced by pressing any of the
buttons. The monitor will continue to display the wheel position, air pressure of the
alarmed wheel position and the words LOW PRESSURE until the problem is corrected. If
the alarm comes on and the FAST LEAK icon appears (see Figure 4-2), this means the
tire is losing air at a rate faster than 4.5 PSI in a 16 second period. The FAST LEAK icon
will only be displayed during the fast leak and will go out when the air quits leaking from
the tire. We suggest that the tire be inspected immediately.
2. SECOND STAGE ALARM FOR 25% LOW AIR PRESSURE
On a level 2 Low Pressure Alarm the monitor will alarm when the pressure has reached
25% below the programmed baseline air pressure. The National Highway and Traffic
Safety Administration considers a tire flat when the pressure is 25% below the tire
manufacturers’ recommended operating pressure. When this happens the backlight on
the monitor screen will light up. The green led light will go out, the red warning light will
begin to flash. The audible beeper will cycle at 2 flashes or beeps per second and the
alarmed wheel position will be shown with the pressure of the low tire. The words LOW
PRESSURE will be displayed on the monitor similar to Figure 4-1. The screen will display
the same information as a Low Pressure Level 1 Alarm. The audible alarm will be silenced
by pressing any of the buttons. The monitor will continue to display the wheel position,

air pressure of the alarmed wheel position and the words LOW PRESSURE until the
problem is corrected. If the alarm comes on and the FAST LEAK icon appears (see Figure
4-2), this means the tire is losing air at a rate faster than 4.5 PSI in a 16 second period.
The FAST LEAK icon will only be displayed when a fast leak is detected and will go out
when the air quits leaking from the tire. We strongly urge you to pull over and inspect the
possible tire damage immediately.
When the low pressure light illuminates, STOP and check your tire(s) as soon as
safely possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire can cause the tire to overheat and lead to tire
failure. Under-inflation also reduces fuel efficiency, tread life, potentially affecting the
vehicles’ handling and stopping ability.
3. HIGH PRESSURE ALARM
The DORAN 360HD monitor is capable of monitoring for a High Pressure Warning. This
is a warning that is displayed when the baseline air pressure is exceeded by 25%. When
this happens the Green light will go out. The audible beeper will beep once per second
and HIGH PRESSURE will be displayed on the monitor screen. This can be caused by
extreme heat generated into the tire.
When the High-Pressure warning appears, STOP and check your tire(s) as soon
as safely possible, and check for the possible cause.
This can happen because of a dragging brake, bad wheel bearing, extreme temperature
conditions, or other mechanical failures that you might not detect. It is suggested that you
check the suspected tire position for a possible mechanical failure.
4. LOST SIGNAL ALARM
The DORAN 360HD monitor is capable of monitoring for
a lost sensor signal (see Figure 4-3). If the monitor is
unable to receive a signal from a sensor for more than 60
minutes an alarm will be displayed for that sensor. This
