[. . . ] In the absence of such purchase receipt, the warranty period shall be one (1) year from the date of manufacture. This warranty shall be invalid if the product is damaged as a result of defacement, misuse, abuse, neglect, accident, destruction or alteration of the serial number, improper electrical voltages or currents, repair, alteration or maintenance by any person or party other than our own service facility or an authorized Service Center, or any use violative of instructions furnished by us. This one-year warranty is in lieu of all expressed warranties, obligations or liabilities. [. . . ] Opening the chassis for any reason will void the manufacturer warranty and presents a dangerous shock hazard. Never get it wet, if anything spills on the unit shut it off immediately and take it to the dealer for service. Use of a surge protector is recommended to decrease chances of equipment damage by voltage surges. OPERATION The MP45 has three modes of operation LEARN, PLAY and RECALL shown by an LED next to the label. * The LEARN mode is for storing preset information in memory. Set the knobs and buttons for the desired sound then press the store button, the display will blink and the knob settings are stored in the preset number on the display. Note: the output level knob is not programmed and is for final volume adjusting, for best results this should be set at about 7 during programming. There are a total of 42 memory locations. * In the PLAY mode the MP45 knobs work manually, the MIDI is disabled and a footpedal can be used to turn on or off the STAGES, BRITE, FX LOOP or GATE switches. * The RECALL mode is for calling up stored presets, these may be accessed with the front panel UP or DOWN buttons, using a MIDI controller such as the ROLLS MP80, or a special footswitch can be used to go up or down. The presets are numbered as MIDI program changes 1 through 42 with change number 43 showing as a 0 in the display. The 0 means the knobs are active and the MP45 is in a play through mode on that preset. On all the other presets the knobs and sliders are inactive since they were programmed earlier. However the buttons are still active, even though they come up as they were programmed. Remote control The MP45 accepts MIDI program change information. The it may be setup to listen on any MIDI channel or "on" for all channels or "OF" to disregard all MIDI data. The MP45 will phantom power the MP80 footpedal and uses pin 1 for ground and pin 3 as power. In order to use phantom power the MIDI cable must have all wires connected on the connectors. [. . . ] An "FP" will show for a moment in the display then the number "1". The MP45 may now be reprogrammed or switched to another mode for use.
