Troubleshooting
Power does not turn on
Make sure that the AC adaptor is correctly connected.
If you’re using batteries, make sure that each battery is securely in place and in the correct orientation. It’s
also possible that the batteries have run down, so you should obtain a new set of batteries.
Refer to: “Connecting the AC adaptor and turning the power on”
(p. 24)
“Installing batteries and turning the power on”
(p. 25)
Make sure that the HOLD switch is turned off. If it is on, the panel buttons and the scrub and shuttle dials
will be inoperable.
Refer to: “Hold switch [HOLD]” (p. 10)
Finder operation is sluggish
If a folder contains a large number of files, operation will be sluggish when you open the Finder, and the
screen will not scroll easily.
If there is a large number of files, operations in the Finder will take more time. Try moving projects in the
folder to a different folder so that the folder contains fewer projects.
Device connected to the L connector does not work correctly
The R-4’s L connector is only for reception. You cannot connect it to a controller that requires transmission
functionality or power supply, and use it to operate the R-4.
Backlight turns off
The Backlight setting in LCD Setup may be set to turn off the backlight when the unit has not been operated
for a while.
Refer to: “4 LCD Setup” (p. 62)
Settings you made have disappeared
If effect settings or system settings you made have reverted to their original state, it’s possible that you
inadvertently reset the R-4 to its factory-set condition.
Refer to: “Executing Factory Reset (Restoring the factory settings)” (p. 69)
Effect parameters you set have been initialized
Effect parameter values will be remembered as long as you don’t change the effect type; they will return to
the default values if you change the effect type. If you’ve made precise settings, it’s a good idea to make a
note of those settings if you want to use them again.
Refer to: “Effects setting” (p. 55)
Can’t operate the panel
Make sure that the HOLD switch is turned off.
If this is on, the panel buttons and the scrub and shuttle dials will be inoperable.
Refer to: “Hold switch [HOLD]” (p. 10)
Project names and folder names in the main switch or Finder are garbled
WAVE file or folder names that contain double-byte characters (e.g., Japanese) are not displayed correctly.
In some cases, it will not be possible to Rename them successfully.
Refer to: “Available characters” (p. 63)
