i recently bought a 4pk, and also bought 2 603ff recievers and a 604fs used, i cant get any of the 3 recievers to bind, i made sure i was on c1 for the 603's and c2 for the 604's. i have tried different reciever battery packs,even tried binding on a different model number, i already have 2 other recievers binded to this radio. i just purchased 4 new 603ff recievers and they wont bind either. has anyone had this problem??? am i doin something wrong???? any help would be great,thx

ya the only time that that has happened to me was
when I was in the wrong mode c1/c2 remember that
when you switch modes you must turn off and then
turn it back on to reset the radio hope this may help

that was one of the first things i checked, on the main menu it shows what your transmitting. the recievers flash green which say's " transmitter transmitting but not able to bind " been tryin for 3 days now to try to figure it out....thx

Nope, probably not doing anything wrong. You've got it set to the correct mode for each RX so that's not it. Send it in to get checked out. If you bought it used like you said, who knows what happened to it before you got it.

When the rx is flashing green hold the bind button down till it flashes red and then it should bind I have had some rxs bind with out doing that and some I have had to hold the bind button down till it flashes red

well i held the button down for several minutes, out of 11 different recievers i got 2 to bind, i have a flash code red and green while holding the bind button and when i let go of the botton it flashes green. i have tried disconnecting all batteries for several minutes. nothing. do the flash fault codes only tell there is a problem while button is pressed or only when bottun is not pressed??????
i just got off the phone with futaba and they r tellin me i got a bad system,dayum!!!!!!!!!!!!!!!!!!

As soon as it starts flashing red let it go don't keep it held down after it starts flashing red

it will only flash red once then green twice, then red once then green twice................

This is from page 29 of the 4PK manual
(Also, on page 28 of the .pdf version, which I cannot post a link to, due to forum rules):

LED status vs receiver's condition:
No signal reception .............................. Red :On
Receiving signals ................................. Green:On
Receiving signals,but ID is unmatched ..... Green:Blink
Unrecoverable failure (EEPROM,etc.) ....... Red and Green turn on alternately

I hope that helps.
