XtremeLink Range Testing Procedure - Updated: 12/07/08

v1.0-v2.x Range Test Procedure

To perform a range test of the XtremeLink system using the transmitter module that has the removable antenna, follow the instructions below. Have someone help you if there is any possibility of the R/C device moving from a stationary location.

Range test for full range receivers:

1. Install the receiver in the R/C device as it will be used.
2. Remove the antenna from the transmitter module.
3. Turn on the radio system so servo movement can be observed.
4. Using flat ground (pavement, low cut grass, or dirt) place the R/C device so that the receiver antenna is no less than 6" from the ground. This might require you elevating the R/C device during the testing.
5. Hold your transmitter waist high, away from your body.
6. Press and hold the PROG button on the transmitter module.
7. Walk around the R/C device completely (360 degrees) at a distance of at least 50 feet, making sure that the transmitter antenna connector is pointed at the R/C device. If at any time you experience a pause in controls, try to reproduce it again and release the button to see if the pause no longer occurs. If the problem does not occur now, check to make sure that your receiver is at least 6" from the ground while testing.
8. With the PROG button still pressed down, walk away from the R/C device while moving the sticks until there is intermittent control. Note the distant of when intermittent operation begins.
9. Continue walking the same distance. If you walked 100 feet before intermittent operation occurred, you would walk an additional 100 feet.
10. Now, without any control, re-install the antenna on your transmitter module (do not release the PROG button). The R/C device should immediately respond. If it does not respond 100% fully, do not use the system and contact Xtreme Power Systems for assistance!
11. Test complete.


Range test for surface or park flyer receivers:

Follow the instructions of above. The range test will be limited to approximately 25 feet instead of 50 feet for full range receivers.

--------------------------------------------------------------------

v3.0 and later Range Test Procedure

Note: due to the fact that the output power (
while pressing the PROG button) is now 1/25th the amount of the previous firmware, new range testing procedures must be followed.

Range test for full range receivers:

1. Install the receiver in the R/C device as it will be used.
2. Turn on the radio system so servo movement can be observed. Note: antenna should be ON the module.
3. Using flat ground (pavement, low cut grass, or dirt) place the R/C device so that the receiver antenna is no less than 6" from the ground. This might require you elevating the R/C device during the testing.
4. Hold your transmitter waist high, away from your body.
5. Press and hold the PROG button on the transmitter module.
6. Walk to a distance of at least 125 feet. If at any time you experience a pause in controls, try to reproduce it again and release the button to see if the pause no longer occurs. If the problem does not occur now, check to make sure that your receiver is at least 6" from the ground while testing.
7. With the PROG button still pressed down, walk away from the R/C device while moving the sticks until there is intermittent control. Releasing the PROG button should restore 100% control. If it does not, do not use the system and contact Xtreme Power Systems for assistance!
8. Test complete.


Range test for surface or park flyer receivers:

Follow the instructions of above. The range test will be limited to approximately 75 feet instead of at least 125 feet for full range receivers.

Flying with the XtremeLink system should be done with the removable antenna positioned straight up OR bent downwards one "notch" from fully straight up.

Do not position the antenna against any transmitter handle. There should be at least 1" separation from any metal handle.

It is absolutely necessary for you to periodically check the antenna connection to make sure that it is tight. If your connection is loose, you can NOT tighten it without opening the unit up and putting a wrench on the backside of the connector. If you spin the connector 360 degrees, it can easily snap the coax, rendering the system useless. We have a lifetime warranty on our products. If you find your connector is loose, you are welcome to send it in and we can tighten it here.

Over tightening the antenna can cause the connector to spin. There is no need for more than basic hand tightening of the antenna. You want it to seat firmly, and cranking it down is not going to improve performance.

The range check must be performed when there is any doubt about the antenna connection.

Periodically check the center pin on the transmitter module's antenna connector. The pin should be nearly flush with the top of the connector. If the pin is pushed down, improper contact will be made. If the pin is severely pushed down, it is posible that the antenna connection will be shorted. A range test would easily reveal this condition.
