2. Mount the transmitter and receive modules on rigid surfaces using appropriate fasteners.

Step 2. Attach video/audio source and receiver equipment, and setup transmission frequency.

1. Connect the video (yellow) /audio (white) leads of the receiver module drop cable to your video/audio receiving equipment (TV, DVR monitor, etc.). RCA - BNC adapters are provided, if needed.

2. Connect the power (red) lead of the receiver module drop cable to the power adapter provided, then plug the adapter into a standard 120 VAC outlet.

3. With your video/audio receiver equipment, check for video and audio signal interference. If this MVL10-WR system is the only one in the vicinity AND you cannot detect any significant video or audio signal interference with your receiver equipment, skip to step 4. Otherwise, continue with the following sub-steps to determine the best transmission channel configuration for your system.

a. Remove the front cover from the receiver module by removing the four screws.

Screws

Removing the cover from the receiver module allows access to the channel select switch. The channel select switch has four positions, channel 1 (CH1), channel 2, channel 3, channel 4, left to right. In the following picture, the switch is in the channel 1 position (factory setting).

MVL10-WR 2.4 GHz Wireless Video Link System Setup and Usage GuideThe MVL10-WR is a reliable and exceptionally easy to install wireless communications link. It includes these features:

•— 700’ range (line of sight)•— 2.4 GHz range broadcast quality FM-synthesized performance the with 4 channels (selectable)•— Transmits video with audio•— Water-resistant enclosures

MVL10-WR components

Each transmitter/receiver pair can be configured to use 1 of 4 channels in the 2.4 GHz range, and both the transmitter and receiver of a pair must be configured to use the same channel. Transmitters and receivers are factory set to use channel 1. If you have multiple MVL10-WR transmitter/receiver pairs in the same vicinity, configure each pair to operate on a different channel.

Step 1. Mounting the Transmitter and receiver modules

1. Select locations for mounting the transmitter and receiver modules with the following considerations:

—— The transmitter and receiver modules can be up to 700 feet apart.—— For best signal transmission, ensure that the Fresnel zone between the transmitter

and receiver is free of obstructions. Use the table below to approximate the minimum transmitter and receiver height from the radius (r) for the line of sight distance (d) and ground clearance. See the following diagram.

b. While monitoring the video and audio output of your receiver, select each channel to determine which channel is the most interference free. Set the switch to this position and record the channel number.

4. Connect your video and audio source equipment (camera, microphone, etc.) to the transmitter drop cable video (yellow) and audio (white) leads. RCA - BNC adapters are provided, if needed.

5. If the receiver module is setup to use channel 1 (factory setting), connect the power (red) lead of the transmitter module drop cable to the power adapter provided, then plug the adapter into a standard 120 VAC outlet. Otherwise, don’t power on the transmitter yet, and perform the following sub-steps to set the transmission frequency to the receiver module setting.

a. Remove the front cover from the transmitter module by removing the four screws. Removing the front cover allows access to the transmission channel select switches.

b. Pry off the channel switch cover using a small blade screwdriver.

CH4 CH3 CH2 CH1

Transmission channels 1 through 4 (CH1 .. CH4) are selected by sliding to ON the switch numbered for the channel (see the table below). Only one channel switch should be ON at any time. In the following picture, only switch 1 (for channel 1) is ON (factory default).

Channel 1 off off off ON

Channel 2 off off ON off

Channel 3 off ON off off

Channel 4 ON off off off

c. Set the channel select switch to ON for channel selected in the receiver module. Verify that all other channel select switches are not ON (off).

d. Reinstall the transmitter channel switch cover by pressing it into place.

e. Connect the power (red) lead of the transmitter module drop cable to the power adapter provided, then plug the adapter into a standard 120 VAC outlet. The MVL10-WR wireless link should now be functional.

6. At the receiver module, check the quality of the video and audio received through the wireless link from your video source. If the video and/or audio signals received are low quality, do the following until an acceptable signal is provided from the receiver module:

a. Verify that all video, audio, and power connections in your system are secure.

b. Use appropriate monitoring equipment to verify that your video/audio source equipment is functioning properly.

c. Recheck the orientation location of the transmitter and receiver modules to verify that the right side of the transmitter module is directly facing the right side of the receiver module, and no interfering structures exist in the Fresnel zone between them. Check for interfering signals from other sources, and take appropriate action to mitigate them.

d. Change the transmission channel you are operating on. Refer to steps 3 and 5 above.

7. If the front covers of the transmitter and/or receiver module(s) were removed, reattach them. Ensure that the cover seal is positioned properly (see picture below). Tighten the 4 cover screws evenly, being careful to not over-tighten them.

Troubleshooting

Problem Possible Solutions

No video or audio

•— Check power, video and audio cable connections. •— Verify that your video source and receiver equipment is functioning properly. •— Verify that the TX and RX module are powered on.

Interference in video or audio

•— Check the RF spectrum in the area for other devices that emit high radiation, such as microwave ovens, 2.4 GHz wireless devices, power equipment, etc.
