A:AnswerIf it is a red blinking light on the transmitter/charger, there is a battery fault detected. This means the one or more of the rechargeable batteries inside the transmitter/charger is having issues. Those batteries themselves may need charged up. You will want to take them out and recharge them. And they suggest only using rechargeable batteries in the unit. You may also go direct to sennheiser.com and download the full info on these including troubleshooting.
A:AnswerOn my brand new set the charge lite took about 30 hours to turn green. Took the batteries out and they read 1.4 volts instead of 1.2 volts which is the normal voltage for Nimh batteries. Took the batteries out to return the set and found that the battery in left earpiece had leaked. I think it was damaged due to overcharging.
A:AnswerYou can do it with the Sennheiser RS 175 RF Wireless Headpones. We connected the headset to the digital output with the provided cord. We then hooked up the soundbar we have with the analog cord provided. So I can hear with the headphones and my husband can hear through the TV speakers or switch over to the soundbar. It works great for us.
