Power On Alert

Keyboard keys light to alert you if you leave power on and do not perform any operation for about 6 minutes. Note that keys light only, and no sound is produced. When this happens, press any button or keyboard key to clear the power on alert.

NOTE

•Power on alert operates only when you are powering the keyboard using the AC adaptor. It does not operate when you are using batteries.

To turn off power on alert

1Press the FUNCTION (LK-215: TOUCH RESPONSE/ FUNCTION) button a number of times until “DEMO 2” appears on the display.

2Use the [+] and [–] buttons to change the setting to “oFF”.

3Press the FUNCTION (LK-215: TOUCH RESPONSE/ FUNCTION) button to clear the setting screen from the display.

Memory Contents

Even when the keyboard is turned off, user song data saved as Song Bank tunes are retained as long as power is being supplied to the keyboard.

Unplugging the AC adaptor when batteries are not loaded or when batteries are dead cuts off the power supply. This causes all keyboard settings to be initialized to the initial factory defaults, and clears all data stored in memory.

Power Requirements

Note the following precautions whenever you want to ensure that current keyboard settings and memory contents are not lost.

•Make sure the keyboard is being supplied power through the AC adaptor before replacing its batteries.

•Before unplugging the AC adaptor, make sure that fresh batteries are loaded in the keyboard.

Make sure that keyboard power is turned off before replacing batteries or unplugging the AC adaptor.

Connecting Headphones (Figure 1)

Connecting headphones cuts off output from the keyboard’s built-in speakers, so you can play even late at night without disturbing anyone.

Audio Equipment (Figure 2)

Connect the keyboard to an audio equipment using a commercially available connecting cord with a standard plug on one end and two PIN plugs on the other end. Note that the standard plug you connect to the keyboard must be a stereo plug, otherwise you will be able to output only one of stereo channels. In this configuration, you normally set the input selector of the audio equipment to the terminal (usually marked AUX IN or something similar) where the cord from the keyboard is connected. See the user documentation that comes with your audio equipment for full details.

Musical Instrument Amplifier (Figure 3)

Use a commercially available connecting cord to connect the keyboard to a musical instrument amplifier.

NOTE

•Be sure to use a connecting cord that has a stereo standard plug on the end you connect to the keyboard, and a connector that provides dual channel (left and right) input to the amplifier to which you are connecting. The wrong type of connector at either end can cause one of the stereo channels to be lost.

When connected to a musical instrument amplifier, set the volume of the keyboard to a relatively low level and make output volume adjustments using the amplifier’s controls.
