Whenever you suspect that the instrument is not performing as it should, please consult
the following information.
No sound is heard from the speakers.
e Is the Local control set to OFF?
e Are headphones connected to the PHONES jack?
e Are all external devices (if any) turned on?
© If you are in the Multi-timbral Mode, do you have the Transmit channel of the
connected device set to something other than 1, 11, 12, 13, 14, or 15?
The damper effect is constantly applied to notes played or the damper
effect cannot be obtained at all.
e Is the cable from the stand connected properly to the main unit?
Refer to Assembly (pages 4 and 5) and connect the cable properly.
Notes played on the keyboard are too high (or low) in pitch.
e Is Key Transposition in effect? (If Key Transpose has been set, the indicator on
the FUNCTION button will be lit.)
Press the FUNCTION button to cancel Key Transposition (the indicator will
go out.)
© Do you have the Master Tuning set appropriately?
Data in the recorder has disappeared.
e Performance data in the recorder will disappear approx. 8 hours after the
power is turned off. Regrettably, there is no way to restore such data once it
has been lost. If you need a more permanent form of storage, you will need to
use a sequencer (Roland's MC-50 or MT-200) to record your songs on floppy
disks.
s Have you possibly pressed the REC button while you had the Track button
held down?
The pitch differs from that of Roland ISM products, or another manu-
facturer's sound generating unit.
e Be sure the Tuning knob on the rear of the piano hasn't been inadvertently
moved. Refer to Master Tuning (page 12), then adjust the Tuning knob until
the piano matches the pitch of the external unit(s).
Operations performed using the panel buttons (such as switching Cho-
rus/Reverb on or off, or Voice selections) cannot be recorded in a se-
quencer.
e Is the Transmission/Reception Mode set to mode HI? Note that each time the
power is turned on, the piano will be in mode I. In order to record operations
you perform using the panel buttons, the piano must be set to mode Hl.
