Always make sure you turn the keyboard off whenever you are not using it. Important Battery Information I The following shows the approximate battery life. · Manganese batteries ......... Approximately 4 hours The above value is standard battery life at normal temperature, with the keyboard volume at a medium setting. Temperature extremes or playing at very loud volume settings can shorten battery life. I Any of the following symptoms indicate low battery power. Replace batteries as soon as possible whenever any of the following occurs. · Dim power indicator · Instrument does not turn on · Display that is flickering, dim, or difficult to read · Abnormally low speaker/headphone volume · Distortion of sound output · Occasional interruption of sound when playing at high volumes · Sudden power failure when playing at high volumes · Flickering or dimming of the display when playing at high volume · Continued sound output even after you release a key · A tone that is totally different from the one that is selected. · Abnormal rhythm pattern and demo tune play · Loss of power, sound distortion, or low volume when playing from a connected computer or MIDI device Using batteries Always make sure you turn off the keyboard before loading or replacing batteries. To load batteries 1. Remove the battery compartment cover. 2. Load six D-size batteries into the battery compartment. · Make sure that the positive (+) and negative (­) ends are facing correctly. IMPORTANT! Improper handling of batteries can cause them to burst and leak, which creates the danger of personal injury or damage due to contact with battery acid. Be sure to note the following important precautions. · Always make sure that the positive (+) and negative (­) poles are facing correctly as indicated near the battery compartment. · To avoid damage caused by leaking batteries, be sure to remove batteries from the keyboard whenever you leave it unattended for long periods (such as when leaving on a trip). · Never mix batteries of different types. · Never mix old batteries with new ones. · Never discard batteries by incinerating them, do not allow their poles to be shorted (connected to each other), never take batteries apart, and do not expose batteries to direct heat. · Replace batteries as soon as possible after any sign they are getting weak. · Never attempt to recharge batteries. 3. Insert the tabs on the battery compartment cover into the holes provided and close the cover. The keyboard may not function correctly if you load or replace batteries with power turned on. If this happens, turning the keyboard off and then back on again should return functions back to normal. E-16 703A-E-018A Using the AC Adaptor Make sure that you use only the AC adaptor specified for this keyboard. Specified AC Adaptor: AD-5 DC 9V jack Auto Power Off When you are using battery power, keyboard power turns off automatically whenever you leave it on without performing any operation for about 6 minutes. When this happens, press the POWER button to turn power back on. NOTE AC adaptor AD-5 · Auto Power Off is disabled (it does not function) when you are using the AC adaptor to power the keyboard. OUT MIDI IN PHONES/ SUSTAIN/ ASSIGNABLE JACK OUTPUT DC 9V To disable Auto Power Off AC outlet Hold down the TONE button while turning on the keyboard to disable Auto Power Off. · When Auto Power Off is disabled, the keyboard does not turn off automatically no matter how long it is left with no operation being performed. · Auto Power Off is automatically enabled whenever you turn on keyboard power. Also note the following important warnings and precautions when using the AC adaptor. WARNING! · Take care to avoid any damage to or breakage of the power cord. Never place any heavy objects on the power cord or expose it to direct heat. Doing so creates the danger of power cord damage, fire, and electrical shock. · Use only the specified AC adaptor. Use of another type of adaptor creates the danger of fire and electrical shock. Settings Tone, rhythm, and other "main keyboard settings" in effect when you turn off the keyboard manually by pressing POWER or when Auto Power Off turns off power are still in effect the next time you turn power back on. CAUTION! · For safety sake, be sure to unplug the AC adaptor from the wall outlet whenever leaving the keyboard unattended for a long time (such as when leaving on a trip). · Always turn off the keyboard and unplug the AC adaptor from the wall outlet when you are not using the keyboard. Main Keyboard Settings Tone number, layer, split, split point, touch response, reverb, chorus, DSP, equalizer, rhythm number, tempo, Mixer Mode settings (channel on/off, tone number, volume, pan pot), keyboard channel, MIDI In Chord Judge on/off, accomp MIDI out on/off, assignable jack setting, accompaniment volume, user area tones (Synthesizer Mode), user area accompaniments, user area DSP IMPORTANT! · Make sure that the keyboard is turned off before connecting or disconnecting the AC adaptor. · Using the AC adaptor for a long time can cause it to become warm to the touch. This is normal and does not indicate malfunction. 703A-E-019A E-17 Memory Contents In addition to the above settings, data stored in the Registration Mode and Song Memory Mode is also retained when keyboard power is turned off. Electrical Power The settings and memory data described above are retained as long as the keyboard is being supplied with electrical power. Unplugging the AC adaptor when batteries are not loaded or when loaded batteries are dead cuts off the keyboard's electrical power supply. This causes all settings to be initialized to their 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. Initializing the Keyboard Use the procedure on page E-65 to initialize the keyboard, which clears all memory data and returns settings to their initial factory defaults. E-18 703A-E-020A
