No sound, only static

The on/ off green light is not lit.  We have checked the connections and the batteries.  We had good sound, but now all we get is static.

    Same problem. sound works for awhile, although mostly through right earphone. Each time a hint of sound comes from the left side, the green light goes off and all I get is static. I removed batteries, unplugged AC power for a minute to re-set, but the same thing happened again in about 10 minutes.

    The green on/off light is lit sometimes and sometimes not. Have tried to tune to all of the three channels and only get static. I followed all the trouble shooting suggestions.

Hi I had the same problem and just emailed Sennheiser.Go to the menu on your TV and change the variable audio output to fixed. I use the headphones through the home theatre so the volume must be max on the home theatre and then you can adjust your headphone volume. It absolutely worked and I don't get anywhere near the static noise when I go to another room with the headphones on that I got previously. Also be sure your audio cable is plugged into the fixed audio output socket. I did not have to do anything with that.

My mother's headphones have worked great until recently. after a visit from some of her grandchildren, they no longer work on the television in her family room where she always used them. i took them to the living room and was able to get them working on that tv, but still no luck on the other tv. any suggestions?

I had the same problem. I guess someone had bumped the channel switch. As soon as I changed the channel on the base of the transmitter, the on/off light worked and the headphones worked fine.

I had no green light, just static etc.

If you have any other wireless equipment nearby it could be worth moving the headphone base station. In my case wireless router and dect phone were close. I moved the base and immediately the headphones started working again.

Bosch W135 water heater Not igniting, no clicking sound. Replaced batteries and still not lighting

i think you need to check the battery holder is good

and your getting the right supply to the internal ignitor board
if it uses 2 batteries then check there connections are metal
and not gone green or other issue with oxides
and the contact and supply isnt so good to the ignitor
and its not working i assume the ignitors board isnt being supplied
or the switching to energise the spark isnt working
or the ignitor board has failed

you can also attach images from a camera
use macro mode and natrual light
or non macro mode

pics are good

more info and some checks

Battery not charging

Sounds like it could be two things with that, first look at the battery symbol, is it flashing orange or is it green. If its flashing orange means you have a bad battery, if its solid green all ok, if its switching between green and yellow its charging. if the symbol isn't lit at all it doesn't detect your battery and try to remove and reinsert battery. Next look at the plug light, is it green?

Hi. I am charging up my battery for my Harley and am using an oxford oximiser 600, but have lost the instructions. I would like to know what the two lights are to either side of the four lights. They...

You have the four coloured lights to show battery state Red - irrecoverable; Orange - 3 to 6 Volts in the battery, Oximiser will attempt recovery; Yellow - 6 to 12 Volts in the battery, Oximiser will charge and and optimise and Green - Full charge, about 14 V, the Oximiser will maintain the charge.

On the left of this you have a Green light to show that the Oximiser is connected to the mains and on the right you have a Red light to show that you have connected the charging leads thewrong way around, i.e. the positive charging lead is on the negative terminal and the negative charging lead is on the positive terminal. This light should be off.

I am able to use this router in wireless mode but cannot get it to work when hard wired to the router. What setting do I need to check?

When you connect the computer to the router with the cable, make sure that it is connected properly and there is no loose connection. Also if you are connecting the computer to the port number 2 on the router then make sure the port light will lit up.
Proper light should lit up.
Check the IP address on the computer.
Check if there is no static IP address on the computer. If there is a static Ip address then set to obtain IP address automatically.

Not charging

It sounds like Amazon might have sold you a defective charger radio shack has a universal charger for your battery. Around 49.00 I got one and it works great I would first have you battery tested by a place like batteries plus to make sure yours is good.
