[NSRCA-discussion] FW: [teamfutaba] Futaba 6EX, 7C and TM-7 Service Advisory- Updated 01/30/08

[Jay Marshall]

Thanks for the latest update John. Looks like mine is one that needs
checking. Wish Radio South (Brunswick) was one of the stations - I'd drive
down. 

I did note that on my 6EX that the battery voltage is displayed immediately
after being turned on. It's almost impossible to turn back off within the
one second "safe" period recommended by Futaba.

This service advisory affects only owners of the Futaba TM-7 module 
and 6EX and 7C FASST systems. Each FASST transmitter contains a 
unique eight digit identification code, programmed at the factory to 
identify the respective transmitter 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 6EX and 7C FASST systems 
were incorrectly coded with a common code number during the 
manufacturing process. These units were subsequently sold prior to 
our awareness of the situation. 

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

We're extremely confident that this is not a widespread problem. 
However, to catch any possible incorrectly coded units in the field 
and to give you peace of mind that your system is not affected, we 
have set up test stations at participating hobby shops throughout the 
country where you will be able to determine -- within a matter of 
minutes -- whether or not your transmitter is affected, at no charge 
to you. There are 100 such Test Stations in place now, and the number 
will be increased to 500 over the next two to three weeks. Please

list for a listing of these testing stations. Or, if you 
prefer, you may send it in to our service center and we will analyze 
it for you at no charge. If any problem is found, it will be 
replaced. We will gladly pay the postage for returning the unit and 
sending it back to you.

If you have questions or concerns, please do not hesitate to contact 
our Futaba Service Center at: 217-398-0007 or via email at: 
service at futaba- <mailto:service%40futaba-rc.com> rc.com. Our staff 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 to the Futaba FASST items with serial numbers as described 
below. To determine if your 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 of the 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 number as 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-flight your aircraft thoroughly prior to flying. When flying at 
a location with other FASST owners, prior to flying we suggest that 
all pilots briefly activate their systems simultaneously to check for 
any interaction between units. If any interactions should occur, do 
NOT fly. Return the unit to the Futaba Service Center for immediate 
replacement. 

2) Each time that your transmitter is turned on, it is imperative 
that you allow the FASST system an adequate amount of time to 
thoroughly boot-up completely before shutting down the transmitter. 
After the battery voltage appears 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 them to be re-linked, we recommend returning them to the 
Futaba Service Center for analysis. This is not expected behavior 
and should be investigated accordingly.
