Programming the Polk's Hobby Tracker III Transmitter

The advanced features of the Polk Tracker III RC transmitter allows for precise configuration of each individual control to maximize your control over the model submarine. As the number of 75 mHz surface radios that are available become less and less, the Polk, with its multi model capability, has become the standard for many RC sub "bubbleheads." Unfortunately, the fellows who wrote the instruction manual for these radios are so familiar with them, that they made the manual nearly impossible for non-engineers to understand! I found some information on about.com that I am going to insert some of my own experience to help you puzzle these beasts out.

Polk transmitters feature a two-track programming system. Track one scans for available frequencies, and allows the user to select the RC model in use and begin operation. Track two is optional, but gives the user total control over each individual mechanism to set the proper trim and sensitivity of each.

Track One Programming
(Be sure your batteries are fully charged. It's not a bad idea to have a spare set or two on hand.)

1.    Hold the "Mode Up" button down and turn on the transmitter to enter track one programming mode.

2.    Scroll through the available menus using the "Mode Up" and "Mode Down" buttons.

3.    Scroll to the "Sel Frq Chn" option to begin frequency selection.

4.    Extend the transmitter's antenna to its full height and flip the "TX" switch to "On" with the "Mode Up" button held down.

5.    Press the "Data +" button to change to automatic detection mode, and wait for the transmitter to find an open frequency.

6.    Scroll down to the "Model Data Save" option and press the "Data +" button to save the selection.

7.    Turn the transmitter off, then back on after a few seconds. Flip the "TX" switch back to "On" if necessary and wait for the transmitter to finish a self test. When it is finished the model name will be displayed onscreen.

8.    Scroll through the other options to customize the transmitter to the particular RC model in use. Additional available options include: select model, alpha name, wing mix, countdown timer, simulator mode, and other general settings.

9.    Save any additional settings in the "Model Data Save" window before proceeding.

Track Two Programming

1.    Turn the transmitter on and verify that the "TX" switch is in the "On" position and the appropriate model is selected under the track one options.

2.    Press the "Mode Up" and "Mode Down" buttons simultaneously to enter track two programming.

3.    Scroll through the available options with the "Mode Up" and "Mode Down" buttons to adjust each of the flight controls individually.

4.    Use the "Chn Inc" and "Chn Dec" to jump between different channels for each control and the "Data +" and "Data -" to make adjustments.

5.    Scroll to the "Data Save/Exit" option and press the "Data +" button to save all adjustments before exiting.
