6. When the battery is installed, you may plug in the

microphone to the bodypack or simply switch on

the handheld transmitter and begin operation.

7. When the system is first operated, the gain of the

transmitter should be adjusted to the vocalist or

speaker who will be using it.

Speak or sing as loudly as possible into the mi-

crophone.

Observe the audio level meter on the receiver.

Adjust the gain control on the transmitter (see

Figures 2 and 4) to prevent over or under-modula-

tion. The gain should be adjusted so that the signal

peaks are no more than +0 dB and that there is at

least 10 dB of audio level meter indication.

8. The squelch control on the front of the receiver

may be adjusted to increase range or reduce

interference. If the squelch control is being ad-

justed, it should be adjusted with the transmitter

off. CAUTIONDECREASING SQUELCH WILL

MAKE THE SYSTEM MORE SUSCEPTIBLE

TO OUTSIDE INTERFERENCE! Use the small

screwdriver supplied with the unit and turn the

squelch control clockwise to reduce interference

from noise and spurious radio signals. To best set

the squelch control, turn the control counter-clock-

wise until you hear noise and interference and then

turn it back clockwise until the noise is squelched

off. This setting will give you the best balance

between noise and reduced range.

9. Before using the system before an audience, it is

a good idea to walk the expected use area to

check for dropouts. To minimize the potential for

dropouts, please observe good antenna place-

ment. When the transmitter is turned on, the RF

meter on the receiver should be illuminated in the

green range to verify it is receiving a strong signal.

10. When the transmitter power switch is turned on,

the red battery light will flash one time if the bat-

tery is good and has adequate strength. If the

red light does not flash or stays on continuously,

the battery is weak and should be replaced.

RACK-MOUNT INSTALLATION
The MR3000 is supplied with rack mounts for single

and double mounting in a standard EIA 19 equip-

ment rack (see Figure 6). 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 MR3000s 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. 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 (pro-

vided 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.

For double mounting of two systems, proceed as

follows:
1. Align the mid-sized brackets (item #2) with the

holes on the adjacent sides of each unit.

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. Attach the supplied extension cables from the

rack connectors to the antenna connections on

the back of the receiver.

4. Place the assembly in to the 19-inch rack enclo-

sure and insert 4 #10-32 x 3/8 Phillips pan

head screws (supplied) in each corner of the

rack ears and secure to the enclosure.
