CONNECTION

• Leave your entire system (including this cassette deck) turned off until all connections between the deck and other components have been completed.

• Connecting the Deck to an Amplifier

• Before connecting the deck to your amplifier, it is a good practice to review your amplifier's instruction manual.

• Use the white plugs for the left channel and red plugs for the right channel.

• Tape Dubbing

• Many stereo amplifiers and receivers have tape dubbing circuitry so that

tape duplication can be performed between two or more tape decks. Review your amplifier's instruction manual for a full explanation of this mode of operation.

• Systems Remote Control

A wired remote control box can be connected to this unit. No remote control box is

included. For remote control, the user should build a remote control box referring to the included schematic diagram (remote control box schematic diagram). Connect the remote control terminal to the remote control jack on the rear panel.

• Connecting Headphones To listen through headphones, plug your headphones into the PHONES jack.

• Installation Precautions

If the deck is placed near an amplifier or tuner, noise (induced hum) or beat interference may result (especially during AM or FM reception). If this occurs, separate the deck from other components or reorient its position.

NOTE:

Use this unit in a horizontal orientation.

When the unit is used with the front panel facing upward (and the unit is in a vertical orientation) or when the front panel is on an incline, t he unit will not operate properly.
