HK 3770

Please refer to the owner's manual for AVR 151 or 151S. The procedure is explained there. The remote control contains a number of pre-programmed command sets that can be activated to control TV sets, disc players and other devices of various brands.

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.

There are five possible reasons for the receiver shutting down. 1. There is a problem internally with the receiver. 2. There is a problem with one or more of your speakers. 3. There is a problem with one or more of your speaker wires. 4. There is a problem with the speaker wiring done on your system. 5. The unit is overheating. No ventilation. First, check the wiring at every speaker terminal at the back of your receiver and at the back of your speakers. A single strand of speaker wire crossing from one terminal to another would be enough to cause the amp to shut down or go into PROTECT. If you do not find any problems with any of the wiring, you should disconnect all speakers from your receiver. If the receiver continues to go into PROTECT, the problem is in the receiver. Please submit a case on the Contact Us page. They will be able to assist you. However, if it turns on, the problem is elsewhere. Begin reconnecting one speaker at a time. Eventually you will connect a speaker that will cause the receiver to shut down. At this point you have found your culprit. On the other hand, it may just be overheating. You must have at least 2 - 3 inches of space between the top of the unit and any shelf or component above the unit. The unit should not be inside a sealed compartment when being used. The unit must be able to breath. There are very powerful amps in these receivers. If they run too hot, they will shut down. An external fan can help this.
