1.0 Setting Up the System
1.1 Transmitter Installation
Have a professional tire retailer install the bands with transmitters in the
wheels. See section 2 for details. Each transmitter has a unique ID and
needs to be installed in the same corresponding position as noted in
Figure on page 11.
1.2.4 If your tire cold inflation pressure is 35 psi, you are done. If it is
something besides 35 psi, complete section 1.3.
1.3 Setting the Baseline (Cold Inflation) Pressure
1.3.1 Set the pressure in all tires to the recommended cold inflation
pressure.
1.3.2 Plug in the display using either provided power cord.
1.3.3 Hold down the “R/D” button until
you hear a beep then release.
1.3.4 Press and release the “SET” button.
The display will show “dd” in place
of the pressure readings.
NOTE:
For hardwired connection, black wire is ground and red is positive.
1.2 Install the Display
1.2.1 Install the supplied antenna to your display unit located at the back of
the unit.
1.2.2 Use the display mount to affix the display unit on the windshield or
dashboard. Do not block the driver’s view. If necessary, adjust the
viewing angle of the display.
1.2.3 Plug the power cord into the display unit and plug the adapter into
auxiliary power supply or hardwire to vehicle electrical system.

The display is now in LEARN MODE and will store the cold inflation
pressure of each tire once it receives a signal from the transmitter. The
process may take up to 8 minutes. If all pressures are not received in 8
minutes, the display will shift back to the monitoring mode. The tire
positions that did not register will display 00. You will need to repeat
section 1.3.2 until a signal is received from all tire positions. Driving the
vehicle will speed up the process. When rotating, the transmitters send
a signal more frequently than when the vehicle is stationary.
If any or all tires positions do not register after performing the
Baseline Pressure setting process at least twice, or if transmitter
signals are intermittent, experimentation with an external antenna
and/or signal booster will be necessary to get the unit to function.
1.4 Using the External Antenna - RF Interference
The system has been tested to work 40 feet, along line-of-sight path
ways. However, tire construction, vehicle construction, electronic
interference and low temperatures all reduce this distance. RF signals
are subject to interference from many types of signals and products,
which can cause errors in the operation of the product. As with cell
phones and other types of electronics using RF signals, signal
interruption can occur and cause lost signal transmission.

External Antenna Installation
Remove the original antenna from the back of the display unit and replace it
with the coaxial wire antenna via display connector.
Install the magnet/antenna underneath the rear of the vehicle, which will give
it the nearest proximity to the transmitters. Thus, increasing signal reception
between the display/receiver and transmitters.
Do not install the magnet/antenna directly on the trailer.
It is the installer/end user’s discretion how to install the antenna and coaxial
wire from the exterior and interior of the vehicle cabin.
Installing the external antenna involves a small degree of experimentation
for maximum signal reception. Temporarily connect the antenna cable to the
display, passing the cable through the vehicle’s door or window. This
temporary connection allows you to test the antenna’s location. If the
location you have selected for the antenna has difficulty in picking up signals
from all tire locations, change the antenna’s location slightly and continue to
test. When signals from all tire locations report, install the antenna
permanently in the vehicle.
Caution: Stay away from transmission, oil and exhaust lines avoiding the
inherent heat from those locations which can melt the coaxial cable.
If proper reception is not achieved with the external antenna, a signal boost
will be required.
A signal booster (part number = 1905) is an optional part for RV’s, fifth
wheels and tow-vehicles and trailers. It enhances the signal from the
transmitters. A signal booster is recommended to effectively receive the
signals from each transmitter, when there may be interference from
electronics, RV construction, length, etc.

2.0 Transmitter Installation
The transmitter comes pre-installed in the mounting cradle. No adjustments
need to be made to the transmitter or its mounting nut.
It is recommended to install the transmitter/cradle at the location of the
wheel’s valve hole so its location is always known during tire mounting, tire
dismounting, and if the need arises, to scan the transmitter.
2.1 Peel off the adhesive paper from the bottom of the transmitter’s cradle.
The adhesive on the cradle prevents the assembly from rotating around
the wheel barrel.
2.2 Adhere the transmitter’s cradle to the left or right of the wheel’s valve
stem. The transmitter can point inward or outward.
2.3 Insert the band through the lowest slot of the cradle.
2.4 Cut off excess band with tin-snips before tightening the worm-drive clamp.
2.5 Tighten the band’s screw to 40 inch pounds using a 7mm ratchet or
Phillips-head driver.
2.6 Lock the wheel on the tire changer. Apply lubricant on both tire beads .
Mount the lower tire bead on the rim. Ensure that the tire bead does not
touch the electronic module during mounting.
2.7 Mount the upper tire bead the same way and inflate the tire to standard
cold inflation pressure. Avoid damaging the transmitter’s antenna.
2.8 Apply soap suds or commercial leak detection solution around the wheel’s
valve to check for leaks.
2.9 Dynamically balance the wheel before it is put back on the vehicle.

3.2 How the System Works
A banded transmitter assembly is installed in each wheel, which
monitors pressure and temperature conditions inside each tire of the
vehicle. This data is wirelessly sent to the receiver that is installed on
the vehicle. The receiver displays the pressure and temperature for
each tire position. When an abnormal condition is detected, the display will
alert the driver.
3.0 System Overview
The Retrofit TPMS kit monitors tire pressure and temperature. It will pro-
vide warnings about abnormal conditions such as low pressure, high pres-
sure, and high temperature.

The display is preprogramed to provide a warning if the pressure drops 20% below or
30% above the cold inflation pressure. It will also give a high temperature warning if
the temperature exceeds 176°F. The high temperature warning point is not adjustable.
The system is shipped with the baseline (cold inflation) pressure set at 35 psi. At this
setting, the display will provide a low pressure warning at 28 psi and a high pressure
warning at 46 psi. You can set the baseline pressure (see Setting the Baseline (Cold
Inflation) pressure in Setting up the System on page 2) up to 144 psi and the display
will automatically provide a low pressure warning at 20% below and 30% above the
baseline setting.

90 psi 72 psi 117 psi
3.3 Normal Monitoring
3.3.1 Stationary State:
The transmitter will transmit tire pressure and temperature data to the
display at 2-minute intervals. As the data is received, the display will
refresh.
3.3.2 Moving State:
The inertial switch in the transmitter turns on when the speed ex-
ceeds 16mph.
The transmitter will transmit tire pressure and temperature data to the
display at 30-second intervals. As the data is received, the display
will refresh.

3.4 Warnings
3.4.1 Low Pressure Warning
If the pressure in a tire is 20% lower than the cold inflation pressure
setting, then the following will occur:
1. The display will show the pressure of the abnormal tire and the dig-
its will flash.
2. An audible alert warning sound will be heard.
3. The abnormal icon will show up.
4. The system will only display the abnormal tire. By pressing “SET”
or “R/D”, you can temporarily view other tires.
The system will not return to normal monitoring until the
problem(s) is corrected.
3.4.2 High Pressure Warning
If the pressure in a tire is 30% higher than the cold inflation pressure
setting, then the following will occur:
1. The display will show the pressure of the abnormal tire and the dig-
its will flash.
2. An audible alert warning sound will be heard.
3. The abnormal icon will show up.
4. The system will only display the abnormal tire. By pressing “SET”
or “R/D” you can temporarily view other tires.
The system will not return to normal monitoring until the
problem(s) is corrected.
3.4.3 High Temperature Warning
When the temperature in a tire exceeds 176°F, the following will oc-
cur:
1. The display will show the temperature of the abnormal tire and the
digits will flash.
2. An audible alert warning sound will be heard.
3. The abnormal icon will show up.
4. The system will only display the abnormal tire. By pressing “SET”
or “R/D” you can temporarily view other tires.
The system will not return to normal monitoring until the prob-
lem(s) is corrected.

3.4.4 Monitor System Malfunction will occur if the display does not receive
a signal from a transmitter(s) in the tire(s) for more than 30 minutes*,
the display screen will display as dashed lines “- - -” .
NOTE:
When the dash lines ”- - -” appears, it will not be dismissed from
the display even if you restart the unit. When the receiver
(display unit) receives an updated signal from the transmitter(s),
the dashed lines will disappear.
If you are not receiving a signal from the transmitter(s), verify the
following conditions.
1. Power off the display unit and restart the system. The system will
return to normal monitoring after properly receiving signals from
the transmitter(s).
2. Check your antenna connection. Verify the center coax pin has not
become dislocated from the antenna.
If the display unit is working properly and it still does not receive
a signal from the transmitter(s), then the transmitter(s) and ID
chip(s) must be replaced simultaneously.
3. “Er” indicates there is no chip in the position, the chip is not
correctly inserted into the display or the chip is not functioning.
