Front Panel Features
If the AVT 100 is in Preset mode (available only by SIS
command, the Windows-based control software, or the
IR Remote), you can change only to a preset channel. To change
the preset, press the Channel buttons to display the numbers of
the programmed presets in incremental or decremental order.
The NTSC and the PAL versions of the AVT 100 have the same
front panel with identical components and appearance. The
following features and functions are available on the AVT 100
front panel.
Initiating Auto-Scan
AVT 100
When Auto-Scan is enabled, the AVT 100 scans all channels and
saves to memory those with an active signal.
TV/CABLE TUNER
To initiate automatic scanning, press and hold both Channel
buttons. After about 2 seconds, the AVT 100 scans through the
channels and saves them to memory.

and Control, for further information.)

Digital display — This 3-digit, 7-segment alphanumeric LED
display indicates the antenna TV or CATV channel being
received (in Tune mode) or the selected channel preset (in Preset
mode).

IR receiver (not visible from the exterior of the unit) — This
sensor receives commands via infrared signals from the optional
AVT 100 IR Remote Control.

Up and Down control buttons — These push-buttons are used
to increment or decrement the channel or preset number. You
can also activate Auto-Scan by pressing and holding both of
these buttons simultaneously for 2 seconds (see Initiating AutoScan, later in this section).
Special Functions
The AVT 100 offers some special functions that are accessible
only by using SIS commands, the IR Remote, and the Windowsbased control software. Refer to chapter 4, Software
Configuration and Control, or the AVT 100 Help for the
commands to enable these functions.
Locking front panel controls (executive mode)
Executive mode disables all front panel controls, locking out the
user from those functions. Putting the AVT 100 in this mode
enhances security by protecting against inappropriate or
accidental changes to settings.
When the AVT 100 is in executive mode, all serial port
commands remain enabled.
Using the Control buttons
Changing the channel
When executive mode is enabled, the AVT 100 displays the
following message on the digital display for 2 seconds:
If the AVT 100 is in Tune mode (factory default):
•
Press the up or down Channel button to tune to the desired
channel. The current channel number is displayed in the
3-digit LED display.
•
Press and hold down one of the Channel buttons to change
the channels rapidly until the button is released. When the
highest channel number available is reached, the display
rolls over and restarts numbering.
Any attempt to use the front panel buttons while the AVT 100 is
in Executive mode causes the LOC (Locked) message to flash.
