Futaba FASST 6EX stopped communicating to receivers
 

We have been away for a few months and now after recharging the receiver batteries only, the Futaba 2.4 6EX does not link up and activate the receiver. This is not a new installation, it had worked fine previously. The green light on the receiver blinks green instead of being on steady. I can't get either of three receivers to respond when I turn the transmitter on.

Any thoughts?

You may want to check the serial number of your transmitter to make sure it does not fall in the 07 or A7 range per the Advisory that occured quite a few years ago:

Futaba 6EX, 7C and TM-7 Service Advisory- Updated 01/30/08

This service advisory affects only owners of the Futaba TM-7 module and 6EX and7C FASST systems. Each FASST transmitter contains a unique eight digitidentification code, programmed at the factory to identify the respectivetransmitter and to allow a receiver to be paired only to that radio’s signal.Recently we have learned that a very small number of the TM-7 modules, and 6EXand 7C FASST systems were incorrectly coded with a common code number duringthe manufacturing process. These units were subsequently sold prior to ourawareness of the situation.

If two or more units, utilizing this common identification code, were to be inuse simultaneously, they may cause interference with one another. Please note:Units which utilize the correct identification code will not be affected bythese units.

If you have questions or concerns, please do not hesitate to contact our FutabaService Center at: 217-398-0007 or via email at: [email protected]. Ourstaff is available to you Monday-Friday, 8am-5pm U.S. Central Standard Time.

Precautionary Measures and Information-

It is important to note that the precautionary measures are relevant only tothe Futaba FASST items with serial numbers as described below. To determine ifyour transmitter might be affected, look on the bottom of the transmitter case.If using the TM-7 module, the serial number is located on the inside portion ofthe module:

6EX: A7xxxxxxx without the “I” (Inspected) sticker
7C 07xxxxxxx without the “I” (Inspected) sticker
TM-7 07xxxxxx without the “I” (Inspected) sticker

The precautionary measures do not apply to systems that utilize a serial numberas noted below:
6EX ALL A8xxxxxxx or systems with the A7xxxxxxx serial number which include the“I” (Inspected) sticker
7C ALL 08xxxxxxx or systems with the 07xxxxxxx which include the “I”(Inspected) sticker
TM-7 ALL 08xxxxxx or modules with the 07xxxxxx which include the “I”(Inspected) sticker

1) As with all radio control equipment, we strongly suggest that you pre-flightyour aircraft thoroughly prior to flying. When flying at a location with otherFASST owners, prior to flying we suggest that all pilots briefly activate theirsystems simultaneously to check for any interaction between units. If anyinteractions should occur, do NOT fly. Return the unit to the Futaba ServiceCenter for immediate replacement.

2) Each time that your transmitter is turned on, it is imperative that youallow the FASST system an adequate amount of time to thoroughly boot-upcompletely before shutting down the transmitter. After the battery voltageappears on the LCD, we recommend allowing the system to remain on at least one(1) additional second prior to turning off the power to the transmitter.

3) If the transmitter and receiver have lost their binding which required themto be re-linked, we recommend returning them to the Futaba Service Center foranalysis. This is not expected behavior and should be investigated accordingly.

Sledge, this would on the bottom of the transmitter next to the Serial number.

But either way, if there is one on not, it still sounds like it needs to come into the service center to be checked.
