1. Place the 3770 in Bluetooth input mode with the BT button on the front panel or the remote. 2. Do a BT search on the phone, until you find HK3770. Then pair with it. 3. Now you can select the HK3770 as audio source on your phone, depending on the phone. On some phones, you can simply begin to play music after performing the pairing, and the HK3770 will play, if it is in Bluetooth input mode, shown on the front panel display. 4. You can control play/pause etc. from either your phone or from the HK3770 remote control. If you want to use the HK3770 remote, you must first press the STEREO Button on the remote control in order to activate the correct remote codes. Now a press on the PAUSE Button on the HK3770 remote will pause the music by placing your phone on pause, and you can restart play by pressing the PLAY Button. 5. To pair another source to HK3770, first deactivate BT on the source presently paired to release new pairing.
