Use and Function of Switches
4.2.1 Frequency Selection Switches:
Frequency selectability is an option on all VT50 Series Transmitters providing RF
frequency control with slide switches accessible through the chassis lid. S-Band units
utilize 8 slide switches; UHF, L-Band, and C-Band units utilize 12 slide switches. Each
switch is uniquely identified (FS1 through FS8, or FS1 through FS12) on the unit label.
To program the desired RF frequency, position the individual switches as shown in the
applicable Frequency Selection Chart, included with product shipment and available as a
download on the applicable Video Product Page of our website
(www.advmw.com/video).
4.2.2 Power Level Switch:
UHF VT50 Series Transmitters may be ordered with nominal RF output power of 2
Watts, 5 Watts, or 10 Watts and may be optionally configured for power selection (2 W /
5 W / 10 W) via a slide switch accessible on the connector side of the transmitter. L, S,
and C-band VT50 Series Transmitters may be ordered with nominal RF output power of
2 Watts or 5 Watts and may be optionally configured for dual power selection (2 Watts /
5 Watts) via a slide switch accessible through the chassis lid. Power selection switches
are inactive if this option is not purchased.
To select the appropriate RF output power level, position the slide switch to HIGH PWR
or LOW PWR (for L/S/C-band units) or 2W, 5W, or 10W (for UHF units) as indicated on
the unit label.
