FRONT PANEL CONTROLS
Front panel controls should be adjusted only with plastic alignment tools. Damage may result if metal tools
are used. Refer to the following figure for location of the front panel controls.
FIGURE 1
The LOW RF LED turns on with low or missing RF input. It also flashes on invalid tuning or mode settings. All
outputs are squelched with low RF or invalid tuning.
The VIDEO ON dipswitch turns all outputs on and off.
The CATV-BCST dipswitch changes the tuning mode. In the CATV position the tuning mode is set by the
tuning mode switch on the top of the demod. The BCST mode tunes NTSC broadcast VHF/UHF channels.
This mode is invalid for all PAL units.
The channel select switches tune the RF input frequency. The set point of these switches is indicated by a
small triangular notch that is perpendicular to the adjustment slot. When tuning by frequency, these switches
are the frequency in MHz, with the .25MHz steps set by the tuning mode switch.
