INTRODUCTION

PR-216 / TV 5-6

High Performance
Personal Receiver

he PR-216/TV 5-6 is a professional

T

quality , personal monitor receiver
designed to meet the high demands of
the TV , motion pictur e production, and
entertainment industries.

In the motion picture industry, this
receiver is used by directors and
dignitaries for remote program
monitoring, as well as for talent cueing
and monitoring for boom-operators
and crew members. It is used in TV
production studios and ENG trucks for
director IFB, talent cueing and camera
crews.

The PR-216/TV 5-6 is our most
advanced, high fidelity , personal
monitor receiver incorporating both
advanced digital and analog
technologies. This receiver offers
superior audio performance with
the convenience of synthesized
frequency agility to accommodate
adverse multi-channel operation.

PR-216 / TV 5-6 CONTROLS

AUDIO OUTPUT JACK: This stereo 3.5 mm audio output jack accommodates

n

any low impedance headphone — either stereo or mono; also, charging input for
rechargeable battery, and auxiliary power input.

VOLUME CONTROL: This control has 50 dB of range to adjust the audio

o

output for a comfortable listening level (clockwise for maximum level).

POWER / RECEIVER ST ATUS INDICATOR:

p

The LED test indicator displays three functions:

1. The indicator will illuminate continuously
when unit is “ON” and
received.

2. A steady slow flash indicates the receiver
is receiving a signal on the tuned channel.

3. A rapid flash of the LED indicator and a
subtle beeping signal indicates a low battery.

ON / OFF SWITCH: This switch turns the

q

receiver on and off.

TV 5 OR 6 SWITCH: This switch

r

determines the band of the receiver.
Set to the left for TV 5 band
(76 MHz-82 MHz). Set to the
right for TV 6 band
(82 MHz-88 MHz).

NO signal is being

CHANNEL SWITCHES:

s

These rotary switches select the
channel. Channel must be the
same as transmitter’s channel.
(See page 6 for frequency selection chart.)

BA TTERY COMPARTMENT: The battery

t

compartment features a hinged battery cover and
an alignment system that ensures proper battery
polarity. Battery installation and removal is facilitated by
simply manipulating the rear of the battery.

PR-216 / TV 5-6 OPERATING INSTRUCTIONS

Setup

a. Check to ensure that the PR-216 receiver’s radio frequency channel is the

same as the associated COMTEK transmitter’s channel.

(Channels are indicated by the rotary switches on the back of the receiver. See page 4.)

b. Open the battery cover on the receiver (see page 8) and insert a new nine
volt alkaline battery (Eveready E522 or equivalent). This type of battery will
offer up to 30 hours of operation. (Replace the battery before every use if the

demand for fail-safe operation outweighs battery cost. The use of carbon batteries is
not recommended.)

NOTE: If a rechargeable battery is to be used, ensure that the
battery has a full charge before use. (See page 9 for battery
charger instructions.)

c. Connect the headphone to the receiver by inserting the headphone plug

into the receptacle on the top of the receiver . The receiver is operating when
the receiver power switch is turned on and the battery status on indicator
illuminates.

NOTE: The headphone cord also functions as part of the
receiver’s antenna system. For optimum performance, this cord
should be fully extended. Coiling or bunching the headphone
cord may reduce the range of the receiver. Also, coil-cord
type headphone cords are not recommended. The receiver
should be carried by the snap-on belt clip (included) or in a
pocket or belt-clip pouch.

d. Set the audio output level control to a comfortable listening volume. This

control is turned clockwise for maximum output level.

PR-216 / TV 5-6 OPERATING INSTRUCTIONS

Frequency Selection (TV channels 5 and 6)

The PR-216 personal receiver has the ability to operate on one of 112 preset
channels between 76.200 MHz and 87.4 MHz (TV channel 5 and TV channel 6).
Channels are designated by both frequency and channel
number. Channels which operate in the TV 5
spectrum are prefixed with a 5 (5-50 is 81.100 MHz).
Channels operating in the TV 6 spectrum are prefixed
with a 6 (6-50 is 87.100 MHz). This channel rastering
makes it easy to determine which TV band you are
operating on. If you are using this system in an area
which does not have a TV station operating on channel 5,
you can use the channels in the TV 5 range. If the area does not
have a station on TV 6, you can operate on one of the TV 6 channels.

(NOTE: It is unlawful to operate a transmitter in a band that is already
occupied by a TV station.) After you have determined the channel on

which you are going to operate, position the TV band switch on the back of the
receiver to indicate the TV band you wish to use. Position the two rotary switches
to indicate the channel. The left rotary switch is for tens and the right rotary switch
is for ones. To select channel 6-17 (83.80 MHz), position the TV band switch to the
right, indicating use of the TV 6 band. Position the left rotary switch to point to 1,
and position the right rotary switch to point to 7. Refer to frequency charts on
pages 5 and 6 for preset selectable frequencies.

Multiple Channel Operation

Simultaneous operation of more than two channels
requires frequency coordination to avoid intermodulation
interference. This interference could result in poor or
unusable performance. When multiple transmitters are broadcasting, the RF
signals will “mix” together generating additional signals. If these
product frequencies are too close to a frequency which you are using,
you will experience this type of interference. This condition is common to
all radio receivers to some extent. This interference produces whistle
and whine type sounds and/or reductions of range. T o avoid this type

of interference, you should select frequencies from one of the standard
groups (see frequency group charts on page 5), or you can use COMTEK’s
frequency selection guide software to determine appropriate frequencies.
