1. Place the receiver where there is a clear line of sight to the area where the transmitter will be used. Extend the receiver’s antennas to full length and separate them 90 degrees.

2. Make sure the sound system’s volume is low or off on the input you intend to use for the wireless.

3. Plug in the receiver’s power adapter into an AC outlet and the other end into the receiver. CAUTION: Please make sure that the AC adapter is the correct voltage for your local requirements.

4. Plug one end of your audio cable (not supplied) into the output connector on the front panel of the receiver.

5. Turn the output level control on the front panel to the 12:00 o’clock position (midway in the control’s range).

6. Setup and adjust the transmitter level as described in the manual.

7. Turn up the level on the mixer or preamp to the desired setting.

8. Speak into the microphone or strum the instrument and, if necessary, adjust the receiver’s output until the volume level from the wireless system approximates the level of an equivalent wired microphone or instrument.

9. “Walk” the expected area of use to check for dropouts or interference. If problems occur, see the troubleshooting section.

1. Insert battery. Slide open the battery compartment cover by pressing lightly with your thumb on the horizontal grooves (at the back end of the transmitter) while gently pulling back.

2. Turn on the transmitter by sliding the power switch (nearest the battery compartment) forward, toward the mic element. Both red and green LEDs above the power switch should be illuminated, indicating power on and good battery condition.

3. Check reception. Observe that the audio carrier light on the front panel of the receiver is illuminated, an indication that the receiver is picking up the signal. Then, “walk” the intended area of use and make sure that there are no barriers to reception or sources of interference.

4. Unmute the audio by sliding the audio switch (immediately below the mic element) towards the windscreen.

5. Adjust the gain if necessary. First, speak or sing into the microphone and listen closely for distortion or hiss. If the gain is too low (hiss) or high (distortion), adjustments are necessary. Gently insert the provided screwdriver (or other 3/32-in. flat head screwdriver) into the hole near the head of the transmitter. Turn lightly until the screwdriver tip drops into the slot in the level control. Gently turn counterclockwise until the control stops (the mic output is attenuated but not “off”). Slowly turn the mic-level control while listening to the audio. If the audio becomes distorted, turn the mic level control counter-clockwise about 1/8 turn.

6. Adjust the squelch control if necessary. The squelch control on the back of the receiver may be adjusted to increase range or reduce interference. Turn the control counter-clockwise to increase range. Caution! Increasing the range will make the system more susceptible to outside interference! If the squelch is being adjusted, turn the transmitter off. Turn the squelch control counter-clockwise until you hear noise or interference. Then, turn the squelch clockwise until the noise is gone.

1. Insert battery. Open the hinged battery compartment by placing your thumb or finger on the indent on the battery door and pull down. When inserting the battery, pay attention to the polarity (+/-) and insert the terminals first into the battery compartment. Close the battery door by sliding the door shut.

2. Turn on the transmitter by sliding the power switch to its on position. Check the condition of the battery by looking at the LED below the power switch. The battery light should flash once and then go out. If the LED stays on, the battery is weak and should be replaced.

3. Prepare the audio source by attaching the lavalier microphone to the user, placing the headset on the user’s head or plugging the cable into the instrument (depending on what type of system you have). Keep the audio muted while plugging in and adjusting the microphone or source.

4. Check reception by observing that the RF carrier light is illuminated on the receiver’s front panel.

5. Turn on the audio transmission by sliding the large mute switch to the “on” position.

6. Listen carefully to the audio and be sensitive of overload distortion and low gain or hiss.

7. Adjust the gain if necessary. Gently insert the provided screwdriver or other 3/32-in. (2.5 mm) screwdriver into the gain adjustment located at the top edge of the battery compartment under the door. 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”). Slowly turn the audio level control clockwise while listening to audio; if the audio becomes distorted, turn the mic level control counter-clockwise about 1/8 turn.

8. Clip the bodypack to the user’s belt or to a pocket. The bodypack can be positioned horizontally or vertically by moving the belt clip attachment. Removing the belt clip attachment screw and moving it 90 degrees will change the orientation.

The receiver and transmitter must be tuned to the same VHF frequency to operate together. Because of the specialized equipment required to adjust these units properly, users cannot change frequencies.

If two or more R100 and/or other VHF/UHF wireless systems are being used in the same location, proper frequency coordination is required to avoid interference. Frequency mixing and spacing must be factored along with local TV stations to determine if conflicts will result from a specific group.

There are many potential sources of interference for your wireless system. Any electronic component that contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards, digital lighting controllers, CD players and computers all emit RF energy that can affect the performance of your wireless system. It is always best to place your receiver as far away from these devices as possible to minimize the potential for of problems.

Fresh 9-volt alkaline batteries from a quality manufacturer will yield the best performance from R100 transmitters. 8.4-volt ni-cad batteries can be used but will yield much shorter operational time. When the transmitter switch is turned on, the battery light will flash one time if the battery is good. If the light does not flash or stays lit continuously, the battery is weak or nearly dead. If the light comes on during use, the battery is weakening and should be replaced as soon as possible.

Attach Bracket to Receiver

1. Fold antennas down and insert the R-Series receiver through the rectangular cut-out as shown.

2. Align the two holes in the bottom of each receiver with the two holes in the bracket. Secure the receiver to the bracket with the 2 #6 Plastite screws provided.

Mounting the Bracket/Receiver on a Rack

1. Secure the bracket to the rack with the 4, 10-32 x 3/8″ screws provided.

2. Fold the antennas up and extend fully. The antennas should be folded 45 from vertical and should not touch the antenna on the adjacent receiver, or any other metal object.

3. Follow the Equipment Set-up procedures as outlined in the R-Series receiver instruction manual for proper set-up and operation of your wireless microphone system.
