UNGO – Application Notes

Obtaining Optimal Range

Mounting the Extended Range Antenna:

1. Clean the mounting area with a quality glass

cleaner or alcohol to remove any dirt or residue.

2. Plug the receiver/antenna cable into the receiv-

er/antenna.

3. Mount the receiver/antenna vertically using the

supplied double-sided tape.

4. Route the receiver/antenna cable to the control

module and plug it into the four-pin antenna con-

nector.

Important:

• To achieve the best possible range, DO NOT

leave the antenna cable bundled up tightly

underneath the dash. Try to extend the cable the

full length during installation.

• DO NOT mount the control module to close the

vehicle’s Body Control Module and/or Electronic

Control Modules.

Mounting the Standard Antenna:

1. Route the antenna as high up as possible,

extending it to its full length.

2. Secure it in place using a cable tie.

Important:

• DO NOT cut or extend the antenna, as it’s tuned

precisely to the control unit.

• Route the antenna away from moving parts under

the dash and from the vehicle’s Body Control

Module and/or Electronic Control Modules.

Mounting the Control Unit:

• Do not mount or secure the control unit to close

to the vehicle’s Body Control Module and/or

Electronic Control Modules.

• Do not mount or secure the control unit to close

sources of heat, such as the heater core and/or

air ducts.

• Ground the control unit to a clean, paint-free

sheet metal location using a factory bolt that

DOES NOT have any vehicle component grounds

attached to it. A screw should only be used when

in conjunction with a two-sided lock washer.

Under dash brackets and door sheet metal are

not acceptable ground points.

It is recommended that all security components

be grounded at the same location.

Turning Off the Anti-Code Grabbing

Technology (a.k.a. Code Hopping):

Although this is a feature designed to prevent the

remote transmitters from being cloned and retrans-

mitted to the control unit, it is virtual impossible to

do. “Code Grabbers” have a very limited range,

usually required to within 5 feet of the remote

transmitter while the button is being depressed.

By turning the off the Anti-Code Grabbing feature,

it can increase the receiving/transmitting range by

30-35%.

Refer to the “System Features Menu” for the Feature

Number and programming instructions.

Double Stacking (2) CR2016 Batteries:

The CR2032 3-volt micro lithium coin cell battery

inside of the SAA474U (4-button) remote transmitter

can be substituted with (2) CR2016 3-volt batter-

ies. This can increase the range between 65-75%,

depending on the surroundings.

Procedure:

1. Insert a small flat head screwdriver into the notch

on the bottom of the remote transmitter.

2. Gently twist the screwdriver to spreading apart

the two halves of the remote transmitter.

3. Open up the remote transmitter exposing the

CR2032 battery and slide it out.

4. Slide (2) CR2016 batteries into the battery holder

with the “+” facing upwards. (It may be easier to

slide one battery in at a time. With the first battery

in place, slide the second battery between the PC

board and battery.)

5. Prior to closing the two halves of the remote

transmitter, verify the batteries are installed correctly

by pressing any of the buttons. The green LED

indicator should illuminate when a button is pressed.

If the LED does not illuminate, double-check the

direction of the batteries. The “+” should be facing

upwards matching the “+” on the battery retaining

clip.

6. Snap together the two halves of the remote

transmitter.
