Section 1 – Introduction
Note: Make sure you have read the IMPORTANT USER NOTICES and PRECAUTIONS sections
before proceeding with the installation instructions.
1.1) Product Description and Basic Operation
The Everyday Wireless Model TX-3 is a synthesized UHF FM data transceiver designed to operate in the
frequency range of 450 to 470 MHz. There are no user controls or adjustments.
The Everyday Wireless Model TX-3 is a half-duplex data communications device providing radio frequency
(RF) data transmit and receive functions. The Model TX-3 transceiver is an all-inclusive unit containing a
synthesized UHF data radio, GPS receiver, and supporting processing overhead to gather, compute, and transmit
vehicle information in real-time. The Model TX-3 design is intended to be used for 12.5 kHz channel data
telemetry applications.
Each Model TX-3 comes pre-programmed to a specific frequency licensed to each user. Reprogramming the
unit to a different frequency can only be accomplished by the manufacturer.
The Model TX-3 processes GPS information and the status of multiple vehicle inputs. Each Model TX-3
transceiver is configured to transmit data packets containing position, vehicle, and trip information at a
predetermined interval (typically every 10 seconds).
The Model TX-3 unit also comes pre-programmed with a vehicle transceiver identification number that dictates
its transmission time slot. When the time slot corresponding with the pre-programmed vehicle number is
approaching, the Model TX-3 prepares its encrypted data packet, checks to make sure the channel is clear, and
then bursts the data at its precise time slot time interval. Because data packets from the Model TX-3 burst
(typically 25 msec.) in a proprietary time slot protocol, message collisions are avoided and higher throughputs
are achieved.
The Model TX-3 has no user adjustments. Maximum output power is pre-set to 45 watts. The Model TX-3
Transceiver unit should only be opened by the manufacturer.

and Installation
• Step drill bit capable of drilling a ¾ inch hole
• 1/8 to 1/4 inch drill bit
• Test light and voltmeter
Antenna and Transceiver Location
Identify a location on the vehicle roof where the antenna will be installed. The antenna should be located on a
flat metallic surface at a minimum of 6 inches from all roof edges. Prior to installing the antenna, identify the
location where the transceiver will be installed.
The transceiver installation location should be in an enclosed area of the vehicle where the power cables and
antenna cables can be easily accessed without potential for damaging the cables. The transceiver location should
also provide protection for the transceiver from moisture and excessive heat.
Once the locations of the antenna and transceiver have been identified, ensure that the antenna cables are
sufficiently long to reach from one location to the other location.
Antenna Installation (AU2-UHF)
1. Drill a starter hole using a 1/8 to 1/4 inch drill bit at the chosen location of the antenna.
2. Use the step drill to drill a 7/8 inch hole to accommodate the antenna.
3. Slide the rubber gasket onto the metal base of the antenna and feed the antenna leads into the
vehicle.
4. Once the antenna leads are inside the vehicle, pass the leads through the plastic wheel nut and the
metal locking nut.
5. Bring the plastic wheel nut and metal locking nut up to the inside of the mounting surface.
6. Secure the antenna in place by tightening the plastic wheel nut and metal locking nut.
7. Feed the antenna leads to the location where the transceiver is located.
Caution: Care should be taken to ensure that there are no kinks in the antenna leads and that the
antenna leads will not be damaged when replacing panels or other interior components that may have
been removed during installation or that may subsequently be removed during vehicle maintenance.
Significant signal strength loss can occur if the antenna leads are subjected to sharp corners and care
should be taken to avoid such circumstances.
Power Cable Installation (PCTX-3-2)
Caution: The Transceiver operates in 12 V negative ground systems only. Check the battery polarity
and voltage of the vehicle before installing the transceiver. Use a test light or voltmeter to ensure that
the transceiver will be powered only when the vehicle key is in the accessory or ignition position.
1. Check to see that there is access from the power source to the transceiver location.
a. If access does not exist, holes should be drilled in a manner that no damage to the vehicle or
its parts will occur.
2. Run the power cable leads from the transceiver to the power source. Keep the plug end of the cable
at the transceiver.

fuse as close to the power source as possible.
4. Connect the free end of the fuse assembly lead to the positive (+) power source of the accessory or
ignition power source.
5. Connect the white lead of the power cable to a suitable vehicle ground connection.
6. Recoil and secure the surplus cable with a suitable cable tie.
a. Be sure to leave enough slack in the cables so that the transceiver can be removed for
servicing while keeping the power applied.
Installing the Model TX-3 Transceiver
Note: Since there are no user adjustments necessary to operate the transceiver, mount the transceiver in
a convenient, yet enclosed and secured location.
1. Find a relatively flat, steel surface on which to mount the transceiver that is within reach of the
antenna cables and power cords.
2. Place the magnet side of the transceiver against the flat surface until a solid mount is made. If a flat
area is not available, contact Everyday Wireless for a mounting bracket.
3. Screw in one of the mounting strap (MSTX-3-3) ends above the top edge of the transceiver (at the
horizontal center of the transceiver). Pull the mounting strap down and over the center of the
transceiver and screw in the other end of the strap below the bottom edge of the transceiver. The
strap should fit tightly over the transceiver.
4. Repeat step 3 with the second mounting strap (MSTX-3-3), but run this mounting strap horizontal,
securing the screws at the left and right edges of the box (at the vertical center of the transceiver).
The strap should fit tightly over the transceiver. The mounting straps should cross in the middle of
the top plate of the transceiver.
5. Connect the antenna leads and the supplied power cable to the transceiver.
Installing Optional Accessories for the Model TX-3 Transceiver
Note: Accessories are supplied with user manuals and installation instructions specific to each
accessory. Please consult Everyday Wireless for a list of accessories and for user manuals and

Section 3 – Maintenance
In order to ensure that the Model TX-3 is always ready for operation, it should be checked periodically so
that potential defects may be discovered and corrected before they develop into any serious damage. A
minimal preventive maintenance program will significantly increase the transceiver’s lifespan.
This section describes the necessary preventive maintenance checks and tests the user can perform to easily
identify most defects and problems. Any other defects or problems discovered during the normal operation of
the system should be noted for future corrective measures.
CAUTION:
This section also describes the corrective maintenance checks that can be performed on the transceiver.
3.1) Maintenance Concept
The maintenance concept for the transceiver is limited to the removal and replacement of the entire unit.
3.2) Preventive Maintenance Requirements
The following is a recommended timetable for performing preventive maintenance checks on the transceiver.
CAUTION:
Inspection
The transceiver should be inspected at least every three (3) months for defects or physical damage developed
during operation. Inspect all the interface cables to and from the system for cracks, breaks, and proper seating
with their mating connectors on the faceplate. Inspect all cables for frayed, broken, or damaged wires. In
addition, inspect all transceiver connections for accumulation of dirt, grease, or any foreign material that can
cause a non-connection. If a cable is found damaged or non-repairable, it should be replaced before operating
the system again.
1. Confirm that the power cord plug is firmly locked into place at the transceiver unit.
2. Verify that the GPS MCX connector is securely in place. Push to confirm that the MCX jack has
remained securely locked into its connector.
3. Verify that the UHF SMA connector is securely fastened.
a. Rotate the SMA connector clockwise to ensure the connection is tight.
4. If applicable, verify that the Everyday Wireless vehicle sensor module connection is firmly
connected to the Model TX-3 transceiver’s DB25 port.
The frequency of inspection should be increased for units exposed to dusty or heavy particulate environments.
Stop the operation of the transceiver immediately if a problem is noted
during normal operation that can otherwise damage the system.
Primary power to the transceiver must be turned OFF when performing
preventive maintenance on the equipment.
