Troubleshooting

■No sound, or very low volume

•Is the correct AC adapter connected, and the power switch set to ON?

Refer to "Getting Connected" on page 7 and turn the power on.

•Are [INPUT] jack and [OUTPUT/PHONES] jack connected correctly to the instrument and amplifier?

Refer to "Getting Connected" on page 7 and establish correct connections. Check volume settings at instrument and amplifier.

•Is the shielded cable defective?

Try replacing the cable.

•Is 707II set to mute condition?

Cancel the mute condition.

•Is [OUTPUT] knob turned down?

Set knob to suitable position.

•Is expression pedal raised?

For some patches, the expression pedal controls the volume. Set it to a suitable position.

■Cannot record from [AUX IN] jack

Is input source set to "GT"? Set it to "AUX".

■Sound is unnaturally distorted

•Adjust level and gain parameters of modules.

•Set BOOSTER or COMP/ISOLATOR to OFF.

•When a guitar with high output is used with the above effects, unwanted distortion may occur depending on DRIVE module effect type.

■High noise levels

•Adjust ZNR parameter. If problem persists, try reducing GAIN.

•If BOOSTER or COMP/ISOLATOR module is used, lower GAIN parameter of DRIVE module.

■Cannot play rhythm pattern or volume is very low

•Is rhythm volume set to low value?

Adjust parameter knob 3 to obtain suitable volume.

■Expression pedal on/off switching does not work properly.

•Try the procedure described in "Adjusting the Expression Pedal" on page 25.

■SmartMedia card cannot be used

•Is [SMART MEDIA] LED lit?

Turn unit off and check whether SmartMedia card is inserted properly.

•Is correct SmartMedia card used?

The 707II can use SmartMedia cards with a capacity from 16 to 128 MB (designed for 3.3V).

•Has SmartMedia card been formatted?

Be sure to format the SmartMedia card in the 707II before use, as described on page 31.
