Installation: Quick
Someprideinworkmanship goes alongway for acleanandpresentable
installationto be proud of.
Important! Test your system before installation, then after installing the
Interface cable, then once more after connecting Interface cable to
WiLo900RX. Troubleshooting will be easier if a problem were to occur.
•Choose a suitable grounded location and mount the WiLo 900RX close
enough to the hydraulic control system so that the 7’ interface cable is
neatly routed between the two.
•Terminate the interface cable wires to power and the control solenoids
as illustrated in Figure 1.
•Plug the interface cable into the WiLo 900RX.

Suitable Location
The WiLo 900RX can be installed on the rear deck inside of the car or in the trunk, but
should be positioned such that:
•The interface cable neatly reaches the hydraulic control wiring or solenoids and
power source with enough slack left over to remove receiver should servicing be
needed.
•Mounting platform is grounded to vehicle chassis.
•The antenna is more than 6” horizontally from any metal such as batteries, pumps
and car chassis.
•The user can easily reach the unit to access controls.
Mounting
Always exercise caution and inspect underside trunk of a car checking for clearance to gas
tank and fuel lines before drilling holes and driving screws.
1. Mark the two mounting holes using the tabs as a guide.
2. Center punch and drill 1/8” holes on the vehicle chassis or a suitable grounded
platform.
3. Remove all metal shavings from holes before installing screws.
4. Position the receiver over the holes and drive one of the two supplied sheet metal
screws and washer to the right mounting tab (facing front).
5. Position interface cable Black ground wire over left mounting tab and drive second
screw and washer.

System Operation: In Depth
InDepthprogrammingand switchfunctions
Receiver Programming Setup
The WiLo 900RX features forty memory locations. Clearing them out and programming only yours will
ensure no other can access your system.
1. Push the POWER switch to turn the receiver ON, ensure the LED is lit.
2. Clearing memory: Press and hold the PROGRAM switch for more than ten (10)
seconds or until the LED turns OFF. The LED will turn back ON for two (2) seconds
after releasing to indicate that all memory locations are cleared.
3. Learn transmitter: Momentarily press the PROGRAM switch and ensure the LED
is blinking. This will indicate receiver is in Learn mode only for the next 17 seconds.
4. Using the transmitter, momentarily press the side power button, this will cause it to
transmit its unique ID to the receiver.
5. Momentarily push the PROGRAM switch again or wait the 17 second time out to
exit the learn mode.
6. The PROGRAM LED will now light whenever that transmitter is activated.
Receiver Timing Setup
This procedure will customize your receiver output ON time to your hydraulic system.
1. Adjust both Front and Rear controls to about the 10 o’clock position.
2. Select mode A on the transmitter and tap the ♠function switch right to dump all
corners.
3. Adjusting the rear: Lift the rear end by holding the ♣to the left, don’t worry, the
output will time out. Take note of the height and tap the ♣to the right to drop the
rear and start over. Adjust REAR control up a little at a time until critical height is
achieved without over extending the cylinders. Once you find your setting, the rear
end can be tapped a little at a time or completely from the bottom by holding the
switch.
4. Adjusting the front: Raise the rear and now using the ♥, tap it to the right to drop
the front end. Lift the front by holding the ♥left, the output will time out. Again, take
note of the height and drop the front end with the same switch. Make little
adjustments to the FRONT control until critical height is reached. Now the front end
can be tapped up in small amounts by tapping the switch or change to mode “B”
and bounce it by holding the switch long enough to allow it to pump then dump,
then hit it again when it lands to pump then dump in one motion.
11

Transmitter Operation
It’s as easy as 1, 2, 3.
After making sure that it is safe to move your ride, hold the transmitter with either your left
or right hand and:
1. Select mode A or B on the bottom of the transmitter and point the antenna up.
2. Squeeze and hold the momentary Power button on the side of the transmitter.
3. Tap or hold one of the function switches to the left or right depending on desired
effect. Example:
a. If hopping is your choice;
i. Select mode A
ii. Raise the rear end up by pushing the ♣to the left multiple times. This
function is pulsed to act as a safety limiter.
iii. Drop the front end by pushing the ♥function switch to the right.
iv. Auto Hop Method: Select mode B, now hold the ♥function switch
to the left to make the system pump then dump. When the front end
comes down, release and hold the switch again for the next bounce.
v. Regular Hop Method: Select mode A, then tap the ♥function
switch to the left to make the system pump then hold switch to the
right to dump as you would normally do.
vi. Since timing the bounce is what you guys do best, instruction ends
here.
Choreography Mode
This function allows more than one vehicle with this system to be controlled with only one
transmitter.
1. Push the POWER switch on all the units that will be controlled and ensure their
LED is lit.
2. Now momentarily press the PROGRAM switch on all the units to be controlled and
ensure their LED is blinking. Note: All outputs are disabled while unit is in
Learn mode.
3. Using only one transmitter, squeeze the side power button.
4. Exit the Learn mode by pressing the PROGRAM switch on all the units again.
All vehicles are now ready to be controlled with that one transmitter. But since all systems
are not created equal, some timing adjustments at the receivers may be needed to keep
them moving in one accord.
When all the dancing is through, clear the receiver’s memories by performing the
Receiver Programming Setup on all the vehicles one at a time with its own transmitter to
avoid programming unwanted transmitters’ IDs and interference during the procedure.

Antenna Orientation
An education on why it’s not good to point.
Antenna orientation is a very important subject that could mean the difference between an
intermittent and short range of operation, to a more consistent and longer range of
operation.
Contrary to popular belief, the signal does not radiate out the tip like lightning shooting
from the end of a magic wand or need to be pointed like a T.V. remote control. But
instead, its signal radiates in a circular direction out the sides of the antenna. In the same
respect, the reception pattern is identical for the receiver antenna.
These simplified drawings illustrate a typical radiation pattern from a transmitting antenna.
Its signal strength is strongest from the sides and gets weaker towards the ends. And
since the receiver antenna also has the same reception pattern, it is beneficial to maintain
the same vertical orientation on both antennas for maximum range.
Pointing antenna up provides proper radiation pattern and range.
Pointing antenna towards vehicle reduces range but still usable when close by.
13

Transmitter Battery Replacement
Whenthejuiceruns out,giveitsome more.
The 3 volt, size 2032, coin cell batteries in the transmitter can be replaced by removing
the two screws holding the bottom cover.
While pushing down on the release tab of the battery holder, tip the bottom down so that
the battery drops out when the battery ejects.
Position the replacement battery in the holder with Positive (+) side on top, then push
down on left side until it snaps flat into place.

Troubleshooting
Whenthingsseemto gowrong,somethingprobably has.
Problem Probabilities and solutions
The receiver doesn’t respond to
commands all the time.
1. Receiver not powered on. Check Power switch
and for +12V and ground to unit.
2. Transmitter ID not recognized. Perform
“Receiver Programming Setup”.
The receiver doesn’t respond
sometimes.
1. Signal fades. Radio signals bouncing off
objects can cancel out, try relocating your
position.
2. Unwanted radio interference. This is
unfortunately one of technologies’ limitations.
3. Other user nearby. This system currently has
only one channel to operate with so co-channel
interference is possible.
Short range. 1. Receiver signal blocked. Make sure receiver
antenna more than 6” from any metal.
2. Antenna polarity. Make sure both antennas are
vertical.
3. Low transmitter battery power. Replace with
fresh pair.
A Pump or Dump function not working. 1. Blown output fuse. Replace any blown fuses
and check for defective solenoid if problem
persist.
Link M Technologies strives for a problem free product. But let’s face it, we live in a fallen
world where things beyond our control do break. So if after trying to resolve the problem it
is found that part of the system has obviously failed, i.e., transmitter does not power up
even with fresh batteries or the receiver does the same, then by all means return unit for
repair or replacement per Link M Technologies’ Warranty Agreement.
