Troubleshooting
The power won’t come on/
the CHECK indicator doesn’t light
Is the specified adaptor (PSA-series,
sold separately) properly connected?
Check the AC adaptor connection (p. 7, p. 8).
* Never use any AC adapter other than one specified
for use with the FDR-1.
Is the battery low or dead?
Replace it with a new battery (p. 14).
* The battery that is supplied with the unit is for
temporary use, intended primarily for testing the
pedal’s operation.
* The use of an AC adaptor is recommended as the
unit’s power consumption is relatively high. Should
you prefer to use a battery, please use the alkaline
type.
* To prevent unnecessary battery consumption, be
sure to disconnect the plug from the INPUT jack
when not using the effects unit (p. 5).
Is your guitar properly connected to the
INPUT jack?
Check the connection once more (p. 7, p. 8).
* The power is switched on only when a cable is
plugged in to the INPUT jack.
* The CHECK indicator shows whether the effect is
being applied or not. It does not indicate whether
the power to the device is on or not.
No sound / low volume
Is your instrument properly connected
to the FDR-1?
Check the connection once more (p. 7, p. 8).
Is the LEVEL knob set too low?
The further counterclockwise you turn the
LEVEL knob, the more the volume is re-
duced when the effect is on. Turn the LEVEL
knob clockwise to increase the volume.
Is the volume turned down on any guitar
amp or effects device you have connect-
ed?
Check the settings of the connected device.
Is the battery low or dead?
Replace it with a new battery (p. 14).
Effect won’t turn off
Could you be in the vibrato rate setting
mode (p. 12, p. 13)?
