INSTALLATION AND CONNECTIONS System Installation After unpacking the unit and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio equipment. These steps need to be done only when the receiver is first installed or when a change is made to the input source equipment.
INSTALLATION AND CONNECTIONS System and Power Connections The HK 3475 is designed for flexible use with external control components and power amplifiers. These connections are easy to make during an initial installation, or at a later date should you choose to upgrade your system. Remote Control Extension If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, an optional remote sensor may be used.
OPERATION Basic Operation The HK 3475 is simple to operate, and very similar to stereo receivers you may have used in the past. This section will explain the use of several features that may be new to you. • Install the two supplied AAA batteries in the remote as shown. Be certain to observe the (+) and (–) polarity indicators shown in the bottom of the battery compartment.
OPERATION 4. Stations may also be tuned directly by pressing the Direct Button ∆, and then pressing the Numeric Keys ˚ that correspond to the station’s frequency. The desired station will automatically be tuned. NOTE: When the FM reception of a station is weak, audio quality will be increased by switching to Mono mode by pressing the FM Mode Button * ß until the Stereo Indicator F goes out.
OPERATION Source Selectors ç, which also changes the input source selection on the HK 3475. Using the Remote Control It is convenient to think of the functions of the remote control buttons in terms of “pages”, where each source device (e.g., CD player) represents its own page of remote functions. The result is that some of the keys will perform different functions depending upon which device page has been selected prior to pressing the key.
OPERATION Programming the Remote Control Although the remote control is preprogrammed at the factory to operate compatible Harman Kardon CD recorders, players and changers, and cassette decks, you may program the remote with control codes that operate other devices. Not all of the buttons on the HK 3475 remote control may be programmed.
OPERATION Step 4: The LED Indicator Ω will remain on for one second, and then blink three times to indicate that it has reset the group of keys for the selected device page. That device page will now operate the factory default set of codes. Programming the Remote Buttons Resetting One Key to Default Setting Step 1: Place the HK 3475 remote control and the remote control for the other device (e.g.
OPERATION Memory Backup This product is equipped with a memory backup system that preserves tuner presets and system configuration information if the unit is accidentally unplugged or subjected to a power outage. The unit’s memory is stored in an EEPROM, and thus the HK 3475 will retain information such as programmed presets without being connected to a main power source virtually indefinitely.
