BATTERY REPLACEMENT

Be sure to replace the battery as soon as possible when the battery check

indicator lights in order to avoid reduced sound quality.

* Be sure to remove the battery if the instrument will not be used for

an extended period of time in order to prevent possible damage

due to battery leakage.

THE CONTROLS

The output jack is an EIAJ-standard 1/4" phone jack. Be sure to use

an appropriate connection cable.

The built-in preamplifier is automatically turned on when a plug is

inserted into the output jack. When not using the instrument, or

when playing it without amplification, be sure to remove the plug

from the output jack so that the preamplifier power is turned off.

Always set the VOLUME control to “0” when plugging in or

unplugging the connection cable.

The battery check indicator (BATT.) will light briefly when a plug is

inserted or removed from the output jack. This is normal and does

not indicate a malfunction.

Be sure to remove the battery if the instrument will not be used for

an extended period of time in order to prevent possible damage due

to battery leakage.
