I would advise contacting Yamaha. There may be an issue with the unit. It’s also possible that software updates to your iPod made the sync not work properly. Just to make sure, double check the connection for debris that might be blocking the dock’s metal contacts.

Here is a link for contacting Yamaha: http://www.yamaha.com/yec/customer/reachus.html?CTID=5010110

There are FAQ links, tech support email and tech support phone numbers.

In the last few days however, the unit is apparently now thinking my 2nd Gen iPod touch is unsupported.

When I place my iPod touch in the dock, I hear a beep and receive the green LED light and the iPod battery indicator shows that it is charging, then I immediately receive 4 quick flashes of the red LED light and the battery indicator of the iPod shows that it is no longer charging. The LED light then changes back to green but no sound is produced by the speaker and the iPod battery reverts to running on its own charge.

Again, the unit worked fine the first two weeks with the same iPod touch.

Please advise. Thank You.

Go to page 1 of your owner’s manual there is a section called “Controls and Functions.” There is a table that explains what the flashing lights mean.

If the LED light lights up green first, then flashes red for just 2 seconds you are using an unsupported iPod.

If the LED light lights up green first, then flashes red continuously the connection has failed (try connecting again.)

If the LED light is flashing red (without having first gone green) then the protection circuitry has been activated. Disconnect the AC adapter and retry in a few minutes.

I hope that helps. As always, feel free to call and talk to one of our salesmen at 1-866-224-6171.

As noted in the updated article, the PDX-30 we sell is the US model, which is set for 120V AC 60Hz power. We do not sell non-US models, but our sister site 4Luggage.com has power adapters and power converters that will allow the PDX-30 to be used in foreign countries.

This unit is powered by regular AC wall power; there is no battery.
