Hi all,

I've recently changed from Flysky to Futaba T6K for my IOM and DF65.  All has been fine for two weeks, but yesterday I got a continuous "beep-beep-beep" (as opposed to "beeeeeeeeeeepppp" 😄) but with no error messages, and it was obviously VERY annoying.  I tried disconnecting the receiver, and powering the transmitter off, but it wouldn't stop.  I finished up just turning the volume of the beep, but that's not a real solution as it stops me easily using the trim.  I changed batteries (AA's on the transmitter) and when I got home used one of my LiFe batteries, but still the beep continues!  I'd even be prepared to do a "factory reset" but can only find  a model reset, which doesn't clear everything.

Any ideas gratefully received!

 

Thanks!

Hi Larry, page 35 of the Futaba manual states that a continuous beep signifies a low Tx battery. If you are sure that your batteries are fully charged then check that the battery alarm is set to the correct voltage.

This is found in the PRMTR 2 menu in your Tx. mine is set to 4.2v

I hope this helps. Cheers Chris H

Thanks for that, but it's not the TX battery (I tried new batteries and changing to a LiFe) as that's a beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep  this is beep, beep, beep which is said to be  something to do with mixing... but there's no message with it, which the book says  press + & - together, but all that does is lock the screen... 

Does it do it on all model memories?  If it does it on a 'blank' model entry then it's nothing to do with mix settings.  Some transmitters think certain mix / switch combinations aren't safe at start-up but they usually tell you what they don't like e.g. throttle not zero for a helicopter.  Try switching it on with the throttle fully closed,

I think it does, but I will check, good call!  Thanks

 

Edit: Yep, it does! throttle fully shut always otherwise it shows an error on the screen.  I've sent an email to the retailer in the hope he has an idea...

Ring Ripmax directly and  select Futaba servicing. They are excellent and turn problems round quickly. It is quite likely that you have got water in one of the trim switches. Although not the same transmitters I have had similar problems through water dripping on the tranny when you lift the boat out.

Thanks Darin, will try that Tuesday (I'm out for their business hours tomorrow)...

Darin, I've just checked and the L/R trim on the winch stick is full right and won't shift back...  Thanks for the pointer!

👍

This is why I don't like electronic trims - you can't see where they are without looking at a setup screen.  For radio sailing it's quite useful to move the throttle (winch) trim for 'high mode' or 'low mode' to windward.  With a mechanical trim you can instantly see where you left it and hence put it back when you want to.  I don't think any body makes a transmitter with mechanical trims anymore so my 1980s JR PCM10 isn't going in the skip yet.

I've spoken to Futaba Service, and was impressed... He told me to try dribbling alcohol in and allow to dry... Awaiting on the timer now.  If that doesn't work, fortunately Ripmax are close to the in-laws so I can drop off...

Hello Guzzilazz.

At least 8 local members have asked me about this exact problem with their Futaba Transmitters this year alone. I must state I am no electronic expert but I am "handy" and have fixed every one.

The problem is the trim switch buttons jam. These are single action momentary switches that are normally "open" (not working). When they jam they go into a normally closed position and allow a live circuit and keep trying to adjust the trim, hence the beep.

Isopropyl alcohol (IPA) will, most of the time, release the button , but you need to get to the switch from inside the transmitter. This means dismantling the whole radio. Quite easy, if you take your time, take photos as you go and just be careful not to damage the ribbon cable to the screen. The screen is held to the chassis with its own screws which you get to through the 2 holes in the mother board. You will see what I mean when you open it up. Don't worry about levers and bits falling out, its obvious where they go when it comes to reassembly.

When you can expose the switch which looks like a tiny button on the front of the mother board, drop the alcohol into it using a cotton bud and keep pressing the button. It may take a while and you may wonder where all the alcohol is going, but don't worry, its evaporating.

Connect the battery, turn the machine on and see if it works, if not repeat flooding and pressing the switch until it does.

Carefully put it back together.

Good luck
