Overview
This manual covers basic configuration and installation of the Media Vision Assistive
Listen System which consists of the MV-ALS-STFM-D (Dante Enabled Stationary Base
Transmitter), MV-ALS-PRFM (Portable Receiver), MV-ALS-AT01 (Helical Antenna), and
MV-ALS-AT02 (Remote Dipole Antenna). Together these devices are classified by the
FCC as a professional install device. To be in compliance with FCC guidelines, the
radios must be installed with one of the approved antennas listed in this document. The
MV-ALS-STFM-D is currently FCC certified for use with three external antennas.
Antenna Part # Description Power Handling

7. Installing single MV-ALS-STFM-D - Rack Kit
Rack Kit (Pictured below)
Includes (In Order):
1. (2) – Rack ears
2. (1) – Linking bars
3. (2) – Rack ear screws
4. (8) – Linking bar screws
5. (8) – Long rack ear
Note: For installation of (2) MV-ALS-STFM-D into Rack System please skip to section 8.
Step 1.
The feet on the MV-ALS-STFM-D are secured and locked in by a pressure fit plug.
Utilizing a flathead screwdriver or comparable tool, remove the (4) feet from the MV-
ALS-STFM-D by inserting it into the foot and gently lift the screw until you are able to
remove it.
Once you have removed the screw, grab the foot and gently pull it out of the MV-ALS-
STFM-D.

Step 2: Rack Ears
A. Attach the short rack ear to the left or right side of the MV-ALS-STFM-D with the four
rack ear screws.
B. Attach the long rack ear to the right or left side of the MV-ALS-STFM-D with four rack
ear screws.

8. Installation of two MV-ALS-STFM-D - Rack Kit
Step 1. The feet on the MV-ALS-STFM-D are secured and locked in by a pressure fit
plug. Utilizing a flathead screwdriver or comparable tool, remove the (8) feet from the
(2) MV-ALS-STFM-D by inserting it into the foot and gently lift the pressure fit plug until
you are able to remove it.
Once you have removed the pressure fit plug, grab the foot and gently pull it out of the

STFM-D should meet to form a complete linking bar indent.
B. Line the linking bar up with the indent between the two MV-ALS-STFM-D. Then
screw in the linking bar screws.
C. Flip the two MV-ALS-STFM-D upside down and align the linking bar with the 4 screw
holes in the middle.
D. Screw 4 linking bar screws into the linking bar.
E. Flip the two MV-ALS-STFM-D over gently and attach the short rack ear to the left
side of the MV-ALS-STFM-D with four linking bar screws.
F. Attach the short rack ear to the right side of the MV-ALS-STFM-D with four rack ear
screws.

F. Place the two MV-ALS-STFM-D into the Rack System and utilize rack ear screws to
secure both ends
9. Helical Antenna Installation
Included:
(1) Helical Antenna
Step 1. Align the Helical Antenna with the BNC Antenna connector.
Step 2. Connect the Antenna and the BNC antenna connector. Secure and lock it into
place.
9. Remote Dipole Antenna Installation
Includes:
(1) Bracket with Mounted Antenna
(1) 25” Coaxial Cable
(6) Stoppers
(6) Screws.
Step 1. Choose the location where you’d like to install the Antenna Bracket.
When selecting the location of your Antenna avoid any metal obstructions or steel
beams between the Antenna and the receiver.
Once you have chosen the position where you’d like to mount the antenna. Utilizing #2
pencil, mark the position.
Step 2: Utilizing a screw driver, screw in the two bracket screws into the spots that were
marked. Do not screw them in all the way.
Step 3. Position the two openings on each end of the bracket onto the screws and slide
the bracket down until it can move no further.
Step 4. Using the cable clips, secure the coaxial cable onto a flat surface. Make sure
that cable clips are at least 4 inches apart.
Step 5. Attach the coaxial cable to the BNC antenna connector on the back of the
transmitter. Secure and lock it into place.
