INTRODUCTION
PR-216
High Performance
Personal Receiver
he PR-216 is a professional
T
quality , personal monitor
receiver designed to operate with
transmitters in the 216-217 MHz
band under Part 95 of the FCC
regulations. This versatile receiver
can tune both standard and
high- fidelity channels for a variety
of speciality applications:
assistive listening, personal cueing,
language interpretation, tour guide
monitoring, and other personal
remote monitoring applications.
The PR-216 receiver incorporates both
advanced digital and analog microcircuit technologies to produce
superior audio performance
with the convenience of
channel-selectability to
accommodate adverse
multi-channel operation.

PR-216 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.
OPTIONAL EnviroMic ON / OFF:
r
Note: If receiver does not have
EnviroMic option, this switch is
non-operational.
NO signal is being
Optional EnviroMic
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 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 OPERATING INSTRUCTIONS
Frequency Selection (216-217 MHz)
The PR-216 personal receiver can operate on one of 76 available channels
between 216 MHz and 217 MHz. COMTEK’s channel designations
indicate both standard non-companded channels and
high-fidelity, companded channels. Channels 1-40
are non-companded channels offering compatibility
with other manufacturers. Channels 41-60 are
high-fidelity , companded channels for use with
COMTEK transmitters. Channels 61-79 are
standard non-companded channels for compatibility
with other manufacturers transmitters. COMTEK
transmitters automatically transmit the proper mode when set
to channels 1-40 for non-companded or 41-60 for companded
channels.
After you have determined the channel on which you are going to operate,
position the two rotary switches to indicate the channel. The left rotary
switch is for tens and the right rotary switch is for ones. T o select channel 41
(216.0250 MHz), position the left rotary switch to point to 4 (X10), and
position the right rotary switch to point to 1 (X1). Refer to frequency charts
on pages 5 and 6 for 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 r eductions of range. To 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. Contact COMTEK to
obtain a free copy of the frequency selection software or download it off
the web at www .comtek.com/support.html

PR-216 OPERATING INSTRUCTIONS
Monitoring Capabilities
Because each monitoring application requires a
different headphone or transducer to best
satisfy each listening need, the PR-216 can
source a strong audio signal (+16 dBu) to
either stereo or mono headphones with
an impedance as low as 16 ohm.
A hearing-aid type button receiver may
be used with impedances as high as
2 k ohm and still produce a strong
audio signal.
The PR-216 is ideal for use with the
COMTEK NTC-102 neckloop
transductor and wireless IR-230
miniature universal-fit ear canal
inductor receiver or hearing aids
having a “T” switch.
Can be used with consumer or
professional headphones.
Can be used with
hearing aid button
receiver for assistive
listening or acoustic
ear tube for IFB
application.
Can be used to
drive neckloop for
use with IR-230
inductor receiver or
hearing aids.

PR-216 OPERATING INSTRUCTIONS
Low Battery Indicator
The LED on the receiver is a multi-function indicator which includes low
battery detection. When the receiver is first turned on, the indicator will
illuminate continuously indicating that the unit is “ON” and NO signal is
being received. When the receiver is receiving a signal on the tuned
channel, the LED will show a steady slow
flash indicating reception. A rapid flash
on the LED indicator and a subtle beeping
signal through the headphone indicates
a low battery . Replace battery as soon as
possible with a new alkaline battery or
charge the rechargeable battery, as
performance of the receiver will be
unpredictable and may vary from audio
distortion to complete failure to operate.
Battery indicator LED
Battery Removal / Replacement
Pull back battery door latch and allow
battery cover door to spring open. T o
remove battery, simply manipulate the
bottom of battery out of the
compartment and remove.
T o insert battery , face
battery with negative
terminal in line with large hole in
battery compartment, press battery
into compartment and close battery door until
it snaps shut. Note: It is not possible to put
battery in backwards.

PR-216 OPERATING INSTRUCTIONS
Battery Charging
1. Make sure that a seven cell 9 volt Ni-MH rechargeable
battery is used with a minimum of 200 mAh capacity .
(Alkaline batteries must not be charged.)
2. Make sure the PR-216 is turned OFF.
3. Note that the red charging indicator on the charger is ON when the PR-216
is plugged into the charger through the audio output jack.
4. When using the NBC 9-2C charger allow the battery to charge for 14 hours
for a full charge. Unit must then be unplugged. When using the
NBC 9-3-1 digital fast charger the charger will automatically end the
char ge cycle and the red LED will change to gr een. W ith this char ger
the unit may be left in the charger until the unit is used.
5. Periodically open the battery compartment on stored COMTEK units to
check for battery leakage. If a battery is leaking, it must be discarded,
and the battery compartment must be cleaned or returned to COMTEK’s
service department for repairs.
