Setting Up

This section contains information about setting up your PSR-290 for playing. Make sure to read this section carefully before using the instrument.

Power Requirements

Although the PSR-290 will run either from an optional AC adaptor or batteries,

Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is more environmentally friendly than batteries and does not deplete resources.

• Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-290 record operation! Doing so can result in a loss of data.

• Never attempt to turn the power off when a “WRITING!” message is shown in the display. Doing so can damage the internal flash memory and result in loss of data.

■ Using an AC Power Adaptor • • • • • • • • • • • • • • • • • • • • • • • • • q Make sure that the [STANDBY/ON] switch of the PSR-290 is set to

STANDBY.

w Connect the AC adaptor (PA-3C, PA-3B, or other adaptor specifically recommended by Yamaha) to the power supply jack.

e Plug the AC adaptor into an AC outlet.

w e

• Use ONLY a Yamaha PA-3C or

PA-3B AC Power Adaptor (or other adaptor specifically recommended by Yamaha) to power your instrument from the AC mains. The use of other adaptors may result in irreparable damage to both the adaptor and the PSR-290.

• Unplug the AC Power Adaptor when not using the PSR-290, or during electrical storms.

■ Using Batteries • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •

For battery operation the PSR-290 requires six 1.5V “D” size, R20P (LR20) or equivalent batteries. (Alkaline batteries are recommended.) When the batteries need to be replaced, the volume may be reduced, the sound may be distorted, and other problems may occur. When this happens, turn the power off and replace the batteries, as described below q Open the battery compartment cover located on the instrument’s bottom panel.

w Insert the six new batteries, being careful to follow the polarity markings on the inside of the compartment.

e Replace the compartment cover, making sure that it locks firmly in place.

• When the batteries run down, replace them with a complete set of six new batteries.

NEVER mix old and new batteries.

• Do not use different kinds of batteries (e.g. alkaline and manganese) at the same time.

• If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery.

Setting Up

Turning On the Power

With the AC power adaptor connected or with batteries installed, simply press the power switch until it locks in the ON position. When the instrument is not in use, be sure to turn the power off. (Press the switch again so that it pops up.)

• Even when the switch is in the “STANDBY” position, electricity is still flowing to the instrument at the minimum level. When you are not using the PSR-290 for a long time, make sure you unplug the AC power adaptor from the wall AC outlet, and/or remove the batteries from the instrument.

• Never attempt to turn the power off when a “WRITING!” message is shown in the display. Doing so can damage the internal flash memory and result in loss of data.

Accessory Jacks

■ Using Headphones• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •

For private practicing and playing without disturbing others, connect a set of stereo headphones to the rear panel PHONES/OUTPUT jack.

Sound from the built-in speaker system is automatically cut off when you insert a headphone plug into this jack.

■ Connecting a Keyboard Amplifier or Stereo System • • • • • • •

Though the PSR-290 is equipped with a built-in speaker system, you can also play it through an external amplifier/speaker system. First, make sure the PSR-290 and any external devices are turned off, then connect one end of a stereo audio cable to the LINE IN or AUX IN jack(s) of the other device and the other end to the rear panel

PHONES/OUTPUT jack on the PSR-290.

Stereo System

■ Using a Footswitch • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •

This feature lets you use an optional footswitch

(Yamaha FC4 or FC5) to sustain the sound of the voices. The footswitch functions the same way as a damper pedal on an acoustic piano — press and hold down the footswitch as you play the keyboard to sustain the sound.

■ Using the MIDI Terminals • • • • • • • • • • • • • • • • • • • • • • • • • • •

The PSR-290 also features MIDI terminals, allowing you to interface the PSR-290 with other

MIDI instruments and devices. (For more infor-

mation, see page 67.)

• To prevent damage to the speakers, set the volume of the external devices at the minimum setting before connecting them. Failure to observe these cautions may result in electric shock or equipment damage. Also, be sure to set the volumes of all devices at their minimum levels and gradually raise the volume controls while playing the instrument to set the desired listening level.

• Make sure that the footswitch plug is properly connected to the

SUSTAIN jack before turning on the power.

• Do not press the footswitch while turning the power on. Doing this changes the recognized polarity of the footswitch, resulting in reversed footswitch operation.
