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.
