VP3 RECEIVER SETUP AND CONNECTIONS
Battery Installation
1. Press down on the OPEN side of the battery compartment cover and slide it in the
direction indicated until it flips open, as shown below in Figure 1.
2. Insert a fresh 9–volt alkaline battery into the receiver. Make sure the battery polar-
ity (“+/–”) is correct.
IMPORTANT: When replacing the battery, use only a 9-volt alkaline battery or
heavy-duty, rechargeable 8.4 volt nicad battery. Carbon–zinc and zinc–chloride
batteries are not recommended.
Mounting the VP3 Receiver
1. If hook–and–loop (VELCRO type) fastener strips are used, attach them to the the
VP3 receiver and the mounting surface.
NOTE: The VP3 receiver can be mounted horizontally or vertically. In either case,
the VP3 antenna must be positioned vertically. Also, the antenna can pivot 180°.
DO NOT attempt to pivot the antenna toward the sides of the case.
2. If you are using a video or movie camera with a “shoe” attachment, remove the belt
clip from the VP3 receiver and install the “shoe” adapter in its place. Then slide the
shoe adapter on the VP3 into the shoe on the video camera.
3. Make sure the receiver antenna is in the line–of–sight of the transmitter.
IMPORTANT: Avoid operating the system near metal surfaces and obstructions,
since they will degrade system performance.
Cable Connections (Figure 2)
1. Connect the receiver audio output to the camera microphone input or to the micro-
phone input on a mixer using the supplied WA460 audio cable. Make sure the
cable hangs freely between the receiver and the audio input.
NOTE: Due to stereo–mono compatibility problems, some cameras equipped
with a stereo audio input may short the receiver audio output. This will not harm the
camera or receiver, but will require use of a

in. stereo–to–mono adapter (Radio
Shack 274–363 or equivalent) between the VP3 output and the camera input. If
the microphone input requires an XLR-type connector, use the Shure WA450
cable (available as an accessory).
2. If headphones are used, plug the headphones cable into the receiver PHONES
connector.
NOTE: Inexpensive headphones may sound distorted when loud audio levels are
used. The distortion may increase as battery power decreases. This distortion,
while audible in the headphones, is not being recorded.
WARNING
The VP3 can produce ear–damaging headphones levels. Turn the
headphones VOLUME control up slowly when making adjustments.
3. If a 12 Vdc (at 100 mA) power source is to be used, plug a dc adapter cable (not
supplied) into the DC power input on the side of the receiver. The 9V battery need
not be removed during 12 Vdc operation.
NOTE: The VP3’s flexible

wave antenna works in tandem with Shure’s unique
reflective counterpoise audio output cables* to achieve superior RF performance.
These specially designed cables function in an audio capacity and form an inte-
gral part of the antenna system as well. The result is extended operating range and
greater immunity to signal “dropouts.”
