SYNTHESIZED FREQUENCY CHANNEL SETUP

Your new MX-3S is a synthesized system. This system allows you to change frequency channels to any channel listed below. With the batteries

installed in the transmitter, the channel and frequency screen will always stay on. This will allow you to change the frequency channels without

having the transmitter power on. This feature allows you to safely change frequencies without interfering with others.

When the transmitter power is in the ON position, you can not change frequency channels.

Changing Frequency Channels:

1. Open the Setup switch cover door located on the right side of the Frequency Channel screen.

2. Press the Setup button down one time. The word SETUP will flash in the Frequency Channel screen.

3. Use the + INC / DEC - keys to select the frequency channel desired.

4. Press the Setup button down one time to end setup.

5. If safe, turn on the transmitter power switch first and then the power switch to the car or truck. Check to make sure everything is working

properly before starting your car or truck.

NOTE 1: When in the setup mode, press both + INC / DEC - keys together will default to CH 61.

NOTE 2: Using the OFF position in the Frequency Channel screen. By pressing the + INC key in the setup mode past Ch 90, you will see

OFF. By setting the Frequency Channel to the OFF position, you can now turn on the transmitter power switch to change models

or setting without transmitting a signal. When the power switch is in the ON position, the Power On icon and the Power on Light

will flash. This will indicate that you are not transmitting any signal. After you have changed your model number or settings, turn

the transmitter power off and go to step 1 to set the desired frequency channel
