DWG: 315109 18 rev. 24-07-00 QuestionsAnswers 1 How can I update the Operating System? Or How can I reload the Operating System? The instrument is equipped with Flash Rom so that you c

14、an update it with the last operating system containing fixes, updates and new features. These updates can be downloaded directly from our web site at Afterwards copy the OS file downloaded in the diskette, using a pre- formatted disk from your instrument prevent possible errors, and follow the instr

15、uctions below: 1- With the instrument turned off, insert the last Operating System disk then turn the instrument on. 2- The display shows Loading OS-DISK clears ALL MEMORY! . 3- Press ENTER then wait about 3 minutes for the OS loading. 4- The display shows Loading successful! , then press ENTER. 5-

16、Turn off the instrument and remove the Operating System disk. 6- As you turn the instrument on, keep rotating the DIAL until the display shows !WARNING! Dial on power-up requests Memory Clear! 7- Press ENTER, you have now completed the update process. 2How can I do a complete SYSTEM RESET? As you tu

17、rn the instrument on, keep rotating the DIAL until the display shows !WARNING! Dial on power-up requests Memory Clear! Then press ENTER. 3What do the pedals make? On this instrument the pedals are fully programmable by the customer, but if you play with a GRAND PIANO style the three pedals change wi

18、th the following functions: Vocal On/Off (left pedal): This pedal switch on or off the vocal processor. Sostenuto (centre pedal): This pedal is a switch control pedal (on/off) which sustains the notes of the key currently depressed, all new notes played after having depressed the pedal are not affec

19、ted, this pedal operates like a grand piano centre pedal. Damper (right pedal): This pedal applies the sustain effect to all notes released. If you release a note after depressing the damper, the note will proceed towards its natural decay according to the type of sound played. The Damper pedal is p

20、articularly effective with Piano type sounds, it is controlled by a Damper Physical Model patented by Generalmusic. 4 Why do the uppermost keys play always sustained? For some piano sounds the notes from E6 to C8 are automatically sustained such as in an acoustic piano. 5Why do all pedals work in re

21、verse mode? The instrument reads the status of the pedals at the power on and assume this status (normally open or normally closed depends by the type of pedal) as the default status in the rest position. The pedals must be inserted before you switch on the instrument. 6 Why does some pedal work in

22、reverse mode? For the same reason explained first you have not to press a pedal while the instrument is switched on and until it is ready to use. 7 I have replaced the DAMPER pedal potentiometer, how do I let position it correctly? Set the potentiometer to have about 700 ohm between pin 5 and 1 of D

23、IN plug with the pedal at the rest position. Note: the Damper potentiometer have a special resistive stroke, when you replace it use the manufacturers part only (code 070556). 8 Why does not the instrument respond correctly? Or Why the initial screen shows a different model at the start-up? (after C

24、PU Board replacing only) The CPU board spare part supplied by Generalmusic have the wrong OS stored on its memory. Before re-loading the right operating system you must erase the old, to do this follow the instructions below: 1- Prepare an OS disk with the same OS contained on the CPU Board (the ver

25、sion is insignificant, if you have already one use it). 2- Begin the procedure of re-loading OS and after about half minute and before the end of loading: press the EJECT button and extract the OS disk, now the OS stored in memory is insubstantial and the CPU board is capable to load a new one. 3- T

26、urn off the instrument and proceed to load the right OS as described above. PS2600-GPS2600-GPS3600 FAQ 9 Why does the instrument not respond to any controls while the display shows the regular initial screen? The communication inside the instrument between the CPU, Controls and Keyboard boards are i

27、n ring mode: if the ring is interrupted the instrument doesnt work, check each board and the connections between them. 10 Why do I hear some noise after I have connected the instrument to a MAC computer using the serial port? The older Controls & Midi I/O board have the pin 8 of S11 socket shorted t

28、o GND, this cause a problem with some MAC computers, to solve the problem disconnect this pin (you can also operate this cut on the cable). 11 Why is the battery level (Edit / General / Battery & Rel.) always low? or Why does the display shows this warning message: Warning! Battery almost discharged

29、, recharge the battery? After a long period of inactivity may be occur that the internal battery backup have not a sufficient time for re-charging during the normal activity, try to leave the instrument switched on for about 12-14 hours. 12 Why does the display shows this warning message: Battery co

30、mpletely discharged instrument re-initialized? After a long period of inactivity may be occur that the internal battery is completely dis-charged, try to leave the instrument switched on for about 12-14 hours. Afterwards if the instrument will lost the data again, replace the battery. 13 Why does th

31、e instrument have an excessive noise on its outputs? (Vocal processor installed) Check the MIC1 and 2 GAIN inputs setting, reduce the gain or mute these inputs in the appropriate screen. Many times the poor quality or the low signal of a microphone affect the S/N ratio. 14 Why does the instrument pl

32、ays regurarly but the display is obscured with the backlight on? Most probably the fault is in the contrast circuit of the LCD, in this instrument the contrast circuit is complex and pass through many boards, check it path entirely following the schematics. 15 In some live stages the instrument is n

33、oisy, Why? The instrument is manufactured to satisfy all International Safety, EMC and RFI standards. To ensure these the instrument must be connected always to the Earth-Ground (via Mains Socket). An eventual bad connection to the ground, as could be happen in some situation, can get worse S/N rati

34、o and RFI influence: check always to have a good connection to the ground on all stages the instrument plays. 19 Spare Part List Legend EU=Specify European Version (230Vac) US=Specify United States Version (115Vac) B=Gloss Black finish M=Mahogany finish W=Gloss White finish Baldwin=Baldwin version G
