8.Turn the receiver off and connect the mixer or other audio system to the receiver XLR Connector or the ¼ inch Line Level Jack.
9.Set the audio mixer or other system input level to minimum.
10.Press the Power switch button in again.
Receiver “Quick Set-up” is complete.
Quick set-up: Transmitter
1.With the Power Switch on the transmitter OFF, install a fresh alkaline battery into the transmitter.
2.Place the transmitter Power Switch to the ON position.
3.The Red Battery Low Light near the display will flash on and then off. The display will also come on and display a group and channel.
4.Press the SET button once and the Group number will flash.
Section 2 - System Description
5.Use the up and down arrows to change the Group number to match the Group number displayed on the receiver. Press SET and the Channel Number will flash.
6.Use the up and down arrow buttons to change the Channel to match the receiver. Press Set and nothing will be flashing. The channel is now set.
7.If you are using a bodypack transmitter, plug the microphone into the transmitter connector. If using a guitar, turn the transmitter off and wait until display is blank. Hold SET down and turn the transmitter on. A guitar symbol should appear on the display. Plug the cord into the transmitter and guitar.
Transmitter “Quick Set-up” is complete.
Quick set-up: System Operation
1.With the transmitter and receiver on, monitor the display screen. Note that the RF (1-100) Bar graph should indicate near the 100 mark. The AF Bar should show very little, if any, indication until you talk or sing into the microphone. While talking or singing in the loudest voice used in performance, adjust the transmitter gain control if necessary to cause the AF Bar Graph to peak near -6 to -3 but not over +3 for best performance.
2.Set the mixer/amp gain.
3.Talk or sing into the microphone or play the guitar at a normal volume. You should hear audio coming out of the system.
4.If using the unbalanced 1/4" output, you may have to adjust the gain (via the control next to the connector on the back panel) to match the level found when singing or playing with a wired connection.
"Quick Set-up" is now complete.

NOTE: Groups 9 and above are set up to work with the other US frequency band (A and B). If you are using a mix of Band A and Band B, scroll down to these groups and use the clearest group.
6.Change Lock-Out: By pressing and holding the UP and DOWN arrow keys together for 3 seconds, the SET key is disabled.To reactivate the SET key, simply press and hold the UP and DOWN keys again for 3 seconds. This feature can be useful when the receiver is in a location where unauthorized personnel have access to the receiver.
7.For set up, make sure the mixer or amplifier input used for the FMR-500 is muted or turned down to a minimum level.
8.Plug an audio cable (not supplied) into the 3 pin XLR or 1/4 inch output of the FMR-500.
a.NOTE: The XLR connector is the preferred connection since the output is balanced and will be more immune to noise for longer runs of cable although either can be used with good results. If the 1/4 inch connector is used, adjust the output level on the back panel to 12 o'clock (midway in the range) to start and adjust later if necessary.
Now refer ahead to transmitter setup and return to step 9 when that is completed.
9.With the transmitter on, speak into the microphone or play the guitar. Turn up the level on the mixer or amplifier until you are able to hear the desired signal. If no audio is present, repeat setup and refer to the troubleshooting section.
NOTE: If the 1/4 inch output is used, it may be necessary to adjust the receiver output until the volume level from the wireless system approximates the level of an equivalent wired microphone/instrument.
10.Squelch Adjustment - The squelch setting can be used to maximize range or immunity to noise. Press and hold Up for 3 seconds. The current squelch setting will be displayed. Adjust the squelch using the UP/DOWN keys. Maximum squelch (9) maximizes noise immunity but limits the range. Minimum squelch (1) will maximize the range but allow more noise to break through the squelch. Press SET to save the new squelch setting.

Rack Mount Installation
The FMR-500 is supplied with rack mounts for single and double mounting in a standard EIA 19"/ 483mm equipment rack (see Figure 3). For rack mounting a single unit, a long (#3) and short (#1) "ear" are used. For dual side-by-side mounting, use the short (#1) "ears" and the mid brackets (#2) from two FMR-500's as shown.
To assemble the rack mount adapters to the FMR-500 proceed as follows:
1.Remove the front Phillips head screws from each side of each unit.
2.Align the correct rack ear or bracket with the holes on the side of the unit. Install the previously removed screws. Insert an additional screw (#2, provided in the parts pack) into the remaining hole. Repeat this step for the opposite side of the unit. Be sure to tighten all screws securely.
Four double mounting of two FMR-500's proceed as follows:
1.Align the mid brackets (#2) with the holes on the adjacent sides of each unit.
2.Install the previously removed screws. Insert an additional screw (#4, provided in the parts pack) into the remaining holes. Tighten all screws securely.
3.Place the two assemblies side-by-side with the mid brackets together. (The left bracket should fit above the right so that the countersinks are visible). Install 4 flat head screws (#5, provided in the parts pack) and tighten them securely.
