CONNECTING SPEAKERS

Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. How to Connect: Red: positive (+) Black: negative ()
One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the SPEAKERS A or B terminals. Use speakers with the specified impedance shown on the rear of this unit. Banana Plug connections are also possible (except for Scandinavian models). Simply insert the Banana Plug connector into the corresponding terminal. *When connecting Banana Plugs to this units SPEAKERS terminals, be sure to tighten the terminal knobs to make contact securely before connections.
Unscrew the knob. Insert the bare wire. Tighten the knob and

secure the wire.

Caution When inserting the stripped ends of the speaker wires as shown above, make sure at least 1/16 inch (1.6 mm) of insulation is inside the wire holders (i.e. no exposed wire is visible) and no loose conductor wire strands are protruding after connection. If wires touch each other or they touch the metal parts of this unit, this unit and/or speakers could be damaged. To prevent speaker wires from coming loose, make sure wire holders are firmly screwed in.
REMOTE CONTROL (PRE AMP) connector
If you have the YAMAHA pre-amplifier CX-1 or CX-2, connect this connector to the REMOTE CONTROL (POWER AMP) connector of the pre-amplifier by using the cable provided with the pre-amplifier. By this connection, the power of this unit is controlled by the pre-amplifiers POWER switch or the POWER key of the remote control transmitter provided with the preamplifier. After the connection is completed, keep the POWER switch of this unit pressed inward (to the ON position). Note If you will not connect the REMOTE CONTROL connectors of this unit and the pre-amplifier, do not connect the cable to either connector. Otherwise, this unit will not function normally.

(U.S.A., Canada and General models)
Notes q There should be no large obstacles between the remote control transmitter and the main unit. q If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter not to work correctly. In this case, reposition the main unit to avoid direct lighting.

Battery replacement

If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes q Use only AA, R6, UM-3 batteries for replacement. q Be sure the polarities are correct. (See the illustration inside the battery compartment.) q Remove the batteries if the remote control transmitter will not be used for an extended period of time. q If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries.

REMOTE CONTROL LEARNING FUNCTION
(U.S.A., Canada and General models of CX-2 only)
The keys on this remote control transmitter can be programmed to learn key-functions from other remote control transmitters without losing the preset key functions. By using this feature, this unit can then be used in place of one or more other remote control transmitters, thus making operation of your various audio and video components more convenient. Use the included user program sheets to indicate a new function learned for each key. Note There may occasionally be instances in which, due to the signal-coding and modulation employed by the other remote control transmitter, this unit will not be able to learn its signals.
TRANSMIT/LEARN indicator YPC-USER-LEARN
YPC: switch Set to this position when using preset key functions (for controlling this unit and/or YAMAHA components). * YPC is the abbreviation of YAMAHA Preset Code. USER: Set to this position when using learned key functions. LEARN: Set to this position when learning new key functions from other remote control transmitters.

Blank keys

These keys have no preset functions and are used only for learning other remote control transmitters functions.

Press this button to reset the internal microcomputer which controls remote control operations. Microcomputer reset is necessary when the remote control freezes. * Pressing the RESET button will not erase learned functions.

CLEAR button

This button is used to clear one or all learned key functions. (Refer to page 16.)

To Learn a New Function

Set to the LEARN position.
2 Press a key on this unit where a new function will be

learned.

Notes When you operate the desired component with this remote control transmitter, TRANSMIT/LEARN indicator will flash steadily. q The originally preset function of a key is still available in the USER position if a new function has not been learned to the key. q Successful learning to a key results in the erasure of previously learned functions and their replacement by the newly learned ones. q If there is no more room in the memory area for a function to be learned, the TRANSMIT/LEARN indicator will flash two times. In this case, even if some keys are not occupied with functions from other remote control transmitters, no further learning is possible.

This unit Other remote control transmitter About 510 cm (24 in.)
Memory back-up All of the learned functions will be retained while you replace the batteries. However, if no batteries are installed for a few hours, the learned functions will be erased and will have to be learned again. Trouble shooting guide q If learning cannot be made successfully, or if this remote control transmitter does not function even though the learning was successful, check the following points: * Check whether the batteries of the other remote control transmitter are weak. Note that even though its batteries may be strong enough to operate the component it was made for, they may be too weak to transfer signals to this unit. If so, replace the batteries of the other remote control transmitter. * Check whether the distance between the two remote control transmitters is too long or too short. q The remote control transmitters batteries are too weak if the TRANSMIT/LEARN indicator does not illuminate or flash, or if the distance or range within which the remote control transmitter can be used decreases. If either occurs, replace the batteries with new ones.
3 Press and hold the key (on the other remote control
transmitter) where the desired new function is. Illuminates
* When the TRANSMIT/LEARN indicator stops illuminating, the learning is finished.
4 Repeat step 2 and 3 until all desired functions are

successfully learned.
