CONTROL PANEL

POWER

This pad turns the XLT-30 On or Off. When the instrument is turned Off, all settings, or modifications to settings default to the preset factory set- tings.

LIGHT

Depress pad to turn the back light On or Off. Prolonged use of the Back Light will have minimal effect on the battery life of the XLT-30.

VOLUME

Depress pad to modify the Volume of the XLT-30. The arrow keys (Up arrow/Down arrow) increase or decrease the Volume to the headphones.

NOTCH

This control allows the user to mask or reject a small range of frequency response. Its purpose is to eliminate a sound (i. e. motor, humming, fans, etc.) that may be interfering with the leak sound. The Notch setting can be moved with the Arrow Keys.

FILTER

The XLT-30 has four different filtering modes.

AL (All Frequencies) – This is the No Filter feature of the XLT-30. No modifications to the signal can be made with the Arrow Keys. Fre- quency range of the All Frequency setting is from 60 Hz to 6 kHz.
