If you don't know the impedance rating of your speakers, it may be, A) printed on the back of the speaker, B) noted in the speaker's owner's manual, C) available by calling your dealer or the manufacturer. If you often or always play two sets of speakers at once, be sure to use the combined impedance of both (see APPENDIX I). Setting the switch. If your speakers are rated at 4 or 6 ohms, set the SPEAKER OPERATING MODE switches to the left hand (4-ohm) position. If you have one pair of 8-ohm speakers, set the switch to the right (8-ohm) position. Should you change speakers, or add extension speakers (which changes the overall impedance) you should reset the Speaker Operating Mode switch at that time. IMPORTANT NOTE: If you are in doubt, use the 4-ohm position, since the power amplifier section of your receiver runs cooler in this mode. Overheating, or the failure of an internal fuse may occur if the 8-ohm mode is used with 4-ohm speakers. Finally, plug in the HK550Vxi / HK440Vxi's own power cord after reading the warnings at the beginning of this manual. We recommend that your receiver be plugged directly into a polarized wall socket. If you must use an extension cord or power strip, check that it is terminated in a polarized plug and rated in excess of the power to be drawn as printed on the back panel of your HK550Vxi or HK440Vxi. After checking all connections one final time, you're ready to turn on your new receiver and begin enjoying its convenient features and great sonic performance. A good habit to get into is to FIRST power up any signal sources not connected to the receiver's switched convenience receptacle (CD player, turntable, tape deck etc). Then the HK550Vxi or HK440Vxi. This will protect your speakers and ears from turn-on thumps (transients). After turning the FUNCTION selector to the appropriate input, play a record or Compact Disc to check out the performance of your new receiver. If you don't get any sound, consult APPENDIX 111 -Troubleshooting. Being able to recall your favorite stations is an extremely convenient feature. The HK550Vxi / HK440Vxi will "remember" the last station preset that you were listening to and tune to that station when you turn the receiver back on. You can add or change presets any time you want. There is no "right" or "wrong" way to use presets. Some people only set a couple of them. Others assign a station to every one. There are, however, several common approaches which you might consider. You might 1) rank stations in order of how often you listen to them, assigning Preset 1 to your most listened-to station; or 2) give stations preset numbers that correspond to their position on the AM or FM dial, with a station "low on the dial" occupying a low preset number, etc. To set a preset: 1. Switch the FUNCTION selector to TUNER. 2. Press the FM 1 / FM 2 / AM selector to choose the broadcast and preset "bank". 3. Tune in a station you wish to preset using the TUNING UP & DOWN buttons and tuning SEEK/MANUAL selector. 4. When the station is tuned in as well as possible, press the MEMORY button. 5. You have eight seconds in which to press a preset button. Push one of them. The appropriate channel (preset) number will light on the tuning section display. If you had previously set that particular preset number with another station, the old preset will be erased. 6. Repeat steps 2-5 for any other FM or AM presets you wish to add at this time. When cleaning your receiver, avoid direct use of dusting sprays, abrasive cleaners or caustics (such as dilute ammonia window cleaning solutions). Use only a mild soap and water solution, applied to a soft cloth, rather than sprayed directly onto the component.
