20 Most Recent Motorola Mobility H681 Bluetooth Headset Questions & Answers

The solid blue light is pairing mode, so you are doing it right. Try shutting both the phone and the H681 off, and turning them back on. We had a similar problem with my girlfriend's new motorolla headset while pairing it to a samsung vibraint. It worked for us after we did that.

I was having the same problem - I ended up just playing with it until it worked again. I found instructions on muting the H700, which is to tap both volume buttons at once. I did that a few times while on a call (I was actually listening to my voicemail), and then I hit the volume up button, and now it works. Not sure if something is loose inside and all I had to to was play around to get it back into place?

Your headset's passkey is '0000' (four zeros). I couldn't find its user guide, but the one for the H680, which happens to be very close to yours, can be found here.
Hope you are able to sort your problems out soon.

Wiring a fridge thermostat typically involves connecting the thermostat to the power source and the compressor. Here's a general guide for wiring a 3-pin thermostat:

1. Identify the Pins: The thermostat will typically have three pins labeled 4, 6, and 3.
2. Connect the Power Source: Pin 4 is usually the common (C) terminal, which connects to the power source. This could be the live wire from your electrical supply.
3. Connect the Compressor: Pin 6 is often the normally open (NO) terminal, which connects to the compressor. This allows power to flow to the compressor when the temperature rises above the set threshold.
4. Ground Connection: Pin 3 is commonly the ground (GND) terminal. This should be connected to the ground wire for safety purposes.

I recommend RadioReference.com, they have detailed lists from all over the United States. In addition to frequency lists, they also include live audio, HAM radio lists, licensing information and a lot more.

I have the same problem. When o remove the interface the led is not flashing as per the instruction manual
