Troubleshooting

Power won’t come on / CHECK

indicator doesn’t light:

Is the specified adaptor (PSA-series;
optional) properly connected?

Check the connection once more (p. 9).

* Never use any AC adaptor other than one
specified for use with the DD-7.

Is the guitar connected properly to the
INPUT-A (MONO) or INPUT-B jack?

Check the connection once more (p. 9).

* The power will not turn on without a plug
connected to the INPUT-A (MONO) or
INPUT-B jack.
* The CHECK indicator shows whether the effect
is being applied or not, and is used to indicate
other effects. It does not indicate whether the
power to the device is on or not.

Is the battery low or dead?

Replace with a new battery (p. 22).

* The battery that was supplied with the unit is
for temporary use, intended primarily for testing
the unit’s operation. For extended use, we
suggest replacing this with an alkaline battery.

Is the MODE knob set to HOLD?

In HOLD mode, the CHECK indicator is
normally off (the effect is off). This flashes
while the pedal is held down (HOLD).
The CHECK indicator lights for several
seconds immediately after the power is
turned on, then goes out.

* For details, refer to “Using the HOLD
(Overdubbing) Function”(p. 15).

Are you in TEMPO mode?

In TEMPO mode, the CHECK indicator
flashes alternately in red and green.

* For details, refer to “Using the Tempo Delay”(p.
12).
