Warning In case of getting seriously injured or killed because of electric shock, short circuit, damage, fire or other dangers, please obey the following warnings. These warnings include but not limited to the following situations: Power/Electric Cable * The rated voltage of this device is fixed. The required voltage is printed on the nameplate of this device. * Check the plug regularly, clean the dirt and ash piled up on the plug. * This digital piano only matches with the provided power cable and plug. 2 * Please don't put electric cable beside heaters or radiators. Don't bend too much or cause damage to electric cable. Don't put any heavy stuff on the wire. Don't put it where it may be run over or trampled to make people stumble. Do Not Open * Please do not open this device and try to dismantle inner components or transform it in any ways. This device does not include any components for users to fix. If you find any problems, please stop using and ask qualified Pearl River service staffs to examine and repair the device. Warning about humidity * I n case of any liquid splashing into the device, please do not get this device rained or use it nearby water, in a wet surrounding or put a container of liquid on it. If any liquid, like water, splashes into the instrument, please cut off power and pull out the electric cable from the AC socket immediately. Then ask qualified Pearl River service staffs to examine and repair the device. * Do not plug with wet hands. 3 Fire * Do not place any burning stuff, like candle, on the instrument. It may cause fire. * When sensing any unusual situations, such as worn away and damage of power cable, sound suddenly stops during playing and the smell and smoke it causes, please turn off the power immediately and pull out plug from the socket. Ask qualified Pearl River service staffs to examine and repair the device. Attention In case that people around you and you get injured or get loss of device and property, please obey the following basic instructions. These instructions include but not limited to following situations. Power/Electric Cable * When pulling out plug from socket, please grab the plug instead of power cable. Drawing directly will cause damage to the power cable. * If not using the instruments for a long time or during a lighting storm, please 4 * Do not connect the instrument to the socket by multiple connector, or it will lower the sound quality, or it will make socket overheat. Assemble Use * Please carefully read the attachment that explains the assemble process. If assembling the instrument in a wrong order, it will damage the instrument and hurt the user. * Please connect the external equipment while the digital piano is off. * Before using, please install the supporting screw and adjust it close to the ground, in case of trampling pedal. Installation place * In case of deformation of control panel and damage to inner components, please do not place this device in an environment with a lot of dirt, vibration, extreme cold and hot (such as, direct sunshine, closing to heater and inside a car under the burning sun) * Please do not use this device near the television, radio, stereo, cell phone or other electronic devices. This may make noise on the device itself and 5 television or radio nearby. * Please do not put this device on unstable place, or it may cause a sudden fall down. * Before moving the device, please pull out all electric cables from the socket. * When you set this device, please confirm the AC socket going to be used is reachable. The device should be connected to the socket with protecting grounding connection. If you find any problems and questions, please immediately turn off the power and pull out the plug from the socket. Even though the power is turned off, there is still a small amount of electricity current flowing though it. If you decide not using this device for a long time, please pull out the plug from AC socket. * This product uses all extreme power switch as a device to cut off from network power. The power switch button is on the right side of the keyboard. When the power button is pressed, it is switched on. When the power button up rises, it is switched off. The graphic and screen in this hand book is only for introduction purpose. It may be different from the instrument you buy. 6 Catalogue Installation Guideline ............................................................................................... 8 Control Panel ............................................................................................................ 9 Power\Adjust Volume\Connect the Headset ................................ .......................... 10 Demo song\Sound .................................................................................................. 11 Function\1) Chord .................................................................................................... 12 2) Octave ............................................................................................................... 13 3)Transpose .......................................................................................................... 14 4)Soundboard resonance\5 ） Effect ...................................................................... 15 6) Reverb ................................................................................................................ 16 7)Chorus\8) Beat ................................................................................................... 17 9)Touch .................................................................................................................. 18 10)Split\Touch switch.............................................................................................. 19 Sound choosing.....................…
