* The included battery is for operation verification purposes only. Therefore, battery life may be short.

* The battery is also used as a power source to maintain settings, maintaining calibration and display mode settings.

When the battery is removed from the unit or when the battery reaches the end of its life, calibration will be reset to 440 Hz and the display mode will be reset to Regular.

When the battery is nearing the end of its life, the TUNER ON/OFF LED will flash. Replace with a new battery as soon as possible.

* The calibration setting is maintained even when the power is off. However, if you remove the batteries or unplug the AC adapter, the frequency will return to the factory setting (440Hz). Also, even if the battery is connected, if you plug in an AC adapter that is not supplying power, the frequency will return to the factory setting.
