LR-600 Operation (cont.) Signal Strength Just as on your cellular telephone, the dots above the Listen logo show the RF signal strength coming from the transmitter. Low RF Signal Program Icon When lit the Program icon indicates the unit is in the program mode that allows you to lock out channels that are not used.
LR-600 Power/Battery Options Power Supply (included with unit) If you are using the LR-600 with the external power supply, connect the power supply to the LR-600 and plug the power supply into a 115VAC/60 Hz outlet. External +12VDC Source If you are using the LR-600 with an external +12VDC battery or power supply, obtain a power connector with following dimensions: 0.098 in.

LR-600 Power/Battery Options (cont.) Internal Batteries If you are using the LR-600 with internal batteries, do the following: Open the battery compartment by removing the thumbscrew and then removing the cover. Slide the battery holder out of the battery compartment.
LR-600 Battery Charging Battery Charging For NiMH battery operation, you must charge the batteries for 13 hours before use. To charge the batteries, plug the unit into the power supply or external +12VDC supply and move the power switch to either CHG or ON. The batteries will charge in either position.
Ext. Internal antenna As shipped, your LR-600 is set up for use with its internal antenna. The internal antenna will work well for a large number of uses, but it cannot be positioned for best coverage. When using the LR-600’s internal antenna, make sure the antenna switch is in the Int position.
LR-600 Setup and Programming Power the unit ON Turn the unit on by sliding the power switch on the rear of the unit to the On position. Channel Selection Using the channel select buttons (UP and DOWN buttons on the rear panel) or the SEEK button, select the desired receive channel.

If you want to use this function, you must program the unit for the channels you are using. For example, you are using 72 MHz channels A, E and I. You would only want the LR-600 to receive on channels A, E, and I. When the Channel Select button has been programmed, the unit will select A the first time the user presses the button;...
LR-600 Equalization Adjustment The purpose of the equalizer is to adjust the sound quality to your specific needs and taste. Use a small screwdriver to adjust the LOW, MID and HI positions. These correspond to the following center frequencies: 250 Hz, 1 kHz and 4 kHz.
It doesn’t matter if the user hears the noise if the transmitter is turned off. The transmitter is located a long distance from the LR-600. The adjustable squelch can be programmed from 0 (no squelch) to a maximum of 20 (highest sensitivity).
LR-600’s, this can be done by cross connecting the units as show below. The audio being input to an LR-600 will not be present on the audio output. Only the received audio from the transmitter will be output on the LR-600. This is done to allow cross connecting without creating an audio loop.
Rotate the bracket to the desired position. Re-tighten the two screws. Mounting Options You can mount the LR-600 to a microphone stand, or you can use the U bracket to directly mount it to any vertical or horizontal surface. Microphone Stand Mounting Locate the microphone stand nut in the included poly bag, or use the nut that comes with the microphone stand.
CAUTION: When installing antennas, ensure the antenna is clear of power lines. NOTES: If the RF signal to the LR-600 is too high, the audio will be distorted. This may happen if you are within 40 feet of the LT-800 transmitter. Consider reducing the...
Listen, have more inherent noise compared to most sound systems. To reduce noise of our systems, Listen uses a noise reduction technology called ListenSQ™. Both the transmitter and receiver must have the SQ feature enabled to achieve the desired results. SQ is available on new Listen systems, including the system you received in this shipment.
*NOTE: There are many varieties of 50 ohm, RG-58 and RG-8 cables. You may purchase a cable that is better or worse than this value. Please check with the cable vendor or manufacturer for exact specifications. LR-600 manual_2006_04_12.indd Sec1:22 LR-600 manual_2006_04_12.indd Sec1:22 4/16/2007 11:0...
Before turning on the transmitter, listen to the wide band channels on the receivers (lettered channels at 72 MHz and channels that start with a”2” for 216 MHz when using a Listen receiver). Listen to the audio through the headphone or via the speaker and choose a channel with the least amount of interference.

Yes, as long as the power switch is in the ON or CHG position. Can I use this product in a motor vehicle? Yes, the LR-600 is designed to work with +12VDC from any vehicle. See page 9 for more information.
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
