Indicates the amount by which the input note differs from the string name displayed
(by the String Name indicator). When the needle reaches the center position (“0”), the
pitch is correct.

vice versa.)
* The internal microphone will not function when an instrument has been connected
to the Input Jack.

This switch serves two purposes; it turns the power
ON/OFF, and provides selection of the operating
mode: AUTO or MANUAL.
Ordinarily you'll use the AUTO mode. When replac-

more convenient.

When“) ” and“ =” light — : Pitch is correct
* When both indicators light simultaneously, the battery is near exhaustion. For
further information, see “Battery Check.”
Whenever the TU-8 is turned on, it will automati-
cally check the charge condition of the battery. For
further information, refer to “Battery Check.”
