Transmitter Setup 1. Open battery compartment, install 9 Volt battery. Make sure to observe proper battery polarity. 2. Adjust channel setting to match channel number shown on receiver channel display. Replace battery cover. 3. If using bodypack transmitter, plug the microphone into the transmitter connector. Operating the System 1. Turn transmitter ON via the ON/OFF switch. After a few seconds, the yellow “Tx On” light should illuminate on the receiver front panel. 2.
2. System Description The Telex FMR-10 Wireless is a series of 10 channel frequency agile UHF wireless systems that combine Telex’s legendary quality and reliability with high value. The transmitters and receivers operate in the UHF frequency range. The well-designed audio circuitry ensures excellent signal-to-noise ratio with accurate sound quality. System Features · 10 Channel Frequency Agile UHF system operation. · Featuring “ClearScan™” which makes for quick and easy system setup.
3. Detailed Setup Instructions 3.1 FMR-10 Receiver Setup & Operation 1. Place the receiver where there is a clear line of sight to the area where the transmitter will be used. 2. Attach either the supplied 1/4-wave antennas or two remotely mounted antennas to the antenna connectors on the rear panel of the FMR-10. Be sure and tighten the connectors securely. If the supplied 1/4-wave antennas are used, they must be oriented at a 90o angle as shown in Figure 2.
CAUTION: Please make sure that the AC adapter is the correct voltage for your local requirements. 4. ClearScan™: The FMR-10 Wireless system features ClearScan™. ClearScan™ automates the process of finding a clear channel to use in setup of your FMR-10 Wireless system. To use ClearScan™, depress and hold down the set button for 3 seconds. When the channel display begins flashing release the set button. The receiver is now searching for a clear frequency by measuring the RF energy present on each channel.
NOTE: If the system is in “lock-out”, ClearScan™ will not function. 7. Make sure the gain setting is muted or turned down on the mixer or amp channel you will connect the wireless system to. 8. Plug the audio cable (not supplied) into the output connector. NOTE: The 3-pin XLR-type connector output level is fixed, and cannot be adjusted. Now refer to details located in the FMR-10 User’s Guide on how to set up the transmitter. Once the Transmitter has been set-up, and turned on... 9.
3.1.1 Rack Mount Installation The FMR-10 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 and short “ear” are used. For dual side-by-side mounting, use the short “ears” and the mid sized brackets from two FMR-10 as shown. To assemble the rack mount adapters to the unit(s) and install into a rack, proceed as follows: 1. Remove the front Phillips head screws from each side of each unit. 2.
2. Install the previously removed screws. Insert an additional screw (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 (Item #5) and tighten them securely. 4. Attach the antenna connectors to the brackets. 5.
3.1.2 Antenna Placement For any wireless system to perform correctly, strong RF signals are mandatory. To maximize signal strength, good antenna placement must be utilized. Although some situations prohibit perfect antenna placement, here are some guidelines: 1. The antennas should be placed in a location with a clear signal path to the transmitter. Walls, ceilings, metal objects, equipment racks, etc. are all signal barriers that will reduce range and performance.
If antennas are remote-mounted, separating them 6 feet (1.8m) or more and keeping them at least 2 feet (.6m) from other barriers will improve performance (see Figure 8). If you are remote mounting the antennas and require strong signal over a large area, consider using highly directional antennas such as a log-periodic. The ALP-450 available from Telex is tuned for frequencies from 450-900 MHz and can provide an additional 5 dB of gain. 3.
3.2 Handheld Transmitter Setup 1. Insert battery. Slide open the hinged battery compartment cover by placing your thumb on the indents of the battery door (at the bottom of the transmitter) and gently pushing down (see Figure 9). Insert the battery, terminal end first, into the compartment, with the smaller positive terminal to the right.
4. Verify Reception. When the transmitter is turned on: (FMR-10) the RF meter will illuminate, indicating that the receiver is picking up the signal. If this does not happen, make sure that the transmitter and receiver are set to the same channels. 5. Unmute the audio by sliding the audio switch (immediately below the mic element) towards the windscreen. Speak or sing into the microphone and you should hear your voice through the PA / sound system. 6. Adjustment of the transmitter audio gain - if necessary.
3.3 Bodypack Transmitter Setup 1. Insert battery. Open the hinged battery compartment by placing your thumb or finger on the indent labeled OPEN on the battery door and pushing down, see Figure 11. When inserting the battery, pay attention to the polarity (+/-) and insert the terminals into the battery compartment first. Close the battery door by sliding the door shut. 2. Set the transmitter channel to match the channel setting on the receiver.
3. Turn on the transmitter by sliding the power switch to its on position. Check the condition of the battery by watching the light below the power switch. The red battery light should flash once and then go out. If the light stays on, the battery is weak and should be replaced.

8. Adjust the transmit gain if necessary. Gently insert the provided screwdriver or other 3/32-in. 2.4mm screwdriver into the gain adjustment located at the top edge of the battery compartment under the door (see Figure 11). The door has to be opened but not swung upward to make adjustments. Turn lightly until the screwdriver tip drops into the slot on the level control. Gently turn the control counterclockwise until the control stops (the audio output is attenuated but not “off”).
4. Guidelines/Recommendations for Best Performance Compatibility The receiver and transmitter must be set to the same channel to operate together. Using Multiple Wireless Systems If two or more FMR-10 Wireless and/or other VHF/UHF wireless systems are being used in the same location, proper frequency coordination is necessary to avoid interference.
Multiple System Setup & ClearScan™ ClearScan™ is most useful for finding operating frequencies for situations where no more than 2 systems will be used simultaneously. When setting up more than 2 systems, use ClearScan™ to choose the first channel of operation. Set up subsequent systems following the channel groupings listed above in the “Using Multiple Wireless Systems” section. Potential Sources of Interference There are many potential sources of interference for your wireless system.
Battery Recommendations Fresh 9-volt alkaline batteries from a quality manufacturer will yield the best performance from your FMR-10 transmitters. Rechargeable 8.4-volt Ni-cad batteries can be used, but will yield much shorter operational time. When the transmitter switch is turned on, the red battery light will flash once if the battery is good. If the light does not flash or stays lit continuously, the battery is weak or dead.
