o Learn more in the “Clear Channel Scan” subsection.

• Always keep the receiver’s two antennas in the upright position.

• Never carry the receiver by audio cable or antennas. • Never carry transmitter by antenna.



7.0 Connection For the Wireless Kit to function, the receiver and transmitter must be properly connected. This is achieved by matching the channel group and channel number on both devices. These figures are displayed, for both the receiver and the transmitter, in the Group/Channel menu (GP/CH menu). This is the default menu that appears when the devices are turned on. The GP/CH menu is shown in Figures 9 and 10. NOTE: Receivers and transmitters can only operate on channels in their given frequency range. This range depends on the location of the user. For more information on frequency ranges consult the Sony Wireless Microphone Package Manual, which is included as part of the LRAD Wireless Kit.

7.1 Manual Channel Selection Manually selecting the channel allows the user to scroll through available channels and select the exact channel they would like to use to connect the receiver and transmitter. To execute a manual channel selection, perform the following steps: Manual Channel Selection on Receiver: 1. Power on the receiver and make sure the screen displays the GP/CH menu (the default

menu). • If this menu is not displayed, use the SELECT buttons (+ and -) to scroll through

menus.

2. Press and hold the SET button until the channel group starts flashing (Figure 9).

3. Use the SELECT buttons to scroll through channel groups. Then press the SET button to choose the desired channel group. The channel group is now set.

Figure 10: Channel Number



• Make sure that the channel group and channel number, and therefore the frequency (displayed at the bottom of the GP/CH menu), match exactly on both the transmitter and the receiver.

• If the channel group and channel number match, the transmitter and receiver should successfully connect.

• If the the transmitter and receiver are connected, black bars will appear on the right side of the screen (as seen in Figures 9, 10, and 11).

o These bars display the A and B tuner signal strength meters. The Wireless Kit will always transmit broadcasts using the strongest of the two signals.

o Also on this screen are the audio level (top-left) and the battery level (top-right).

• If the channel group and channel number match but the transmitter and receiver do not connect, cycle the transmitter’s power (turn the transmitter off and back on). This should connect the two devices.

7.2 Clear Channel Scan Along with manually choosing the desired channel, users also have the option of performing a clear channel scan. By initiating a clear channel scan, the user is tasking the receiver to scan for the best available channel in a given channel group. The scan seeks out the quietest channel in order to ensure audio is relayed clearly from the transmitter to the receiver. To initiate a clear channel scan, perform the steps listed on the following page. NOTE: The desired channel group must already be selected before performing the clear channel scan.



Clear Channel Scan on Receiver: 1. Use the SELECT buttons to scroll through menus until the CLR CH SCAN menu is displayed.

2. Press and hold the SET button until the GP ALL + section starts flashing (Figure 11).

2. After matching the channel group and channel number on both devices, cycle the transmitter’s power. This should connect the two devices.

Figure 11: GP ALL + Section



7.3 Daisy Chain: Connect One Transmitter to Multiple Receivers Several LRADs can be connected to maximize broadcasting effectiveness via daisy chain. In a daisy chain configuration, one transmitter is capable of broadcasting to multiple receivers, with each receiver attached to a corresponding LRAD. This configuration allows the user to remotely broadcast a single message through multiple LRADs, creating even greater operational flexibility and broadcasting range. To daisy chain, perform the following steps.

1. Make sure that all desired receivers are set to the same channel group and channel number.

2. Set transmitter to match this channel group and channel number. • You may need to cycle the transmitter’s power to connect the daisy chain.
