Volume Control

Rotating the Volume knob on the front panel increases and decreases the audio volume in up to 100 steps. When this knob is turned, the LCD window displays a bar graph representation of the volume level for 0.3 seconds before returning to the previous menu. In addition, the volume percentage is displayed in the upper-right corner of the LCD screen.

Volume adjustment can be made from the front panel at any time during tuner operation.

Resetting from the Rear Panel

The rear panel contains a recessed Reset button that initiates four levels of resets. To select a reset level, use a pointed object such as a small Phillips screwdriver to press and hold the button while the tuner is running (modes 2 through 4) or while you are applying power to it (mode 1). The adjacent Reset LED provides feedback on the current reset mode.

The table on the next page provides a summary of the four reset modes.

CAUTION: Review the reset modes carefully. Using the wrong reset mode could result in unintended loss of flash memory programming, port reassignment, or a tuner reboot.

NOTES: • The reset modes are separate functions, not a continuation from mode 1 to mode 5.

• There is no reset mode 2 for the AVT 200HD.
