QUICK START
To start using your beltpack immediately:
1. Connect the appropriate 3-pin XLR line cables from an
active TW intercom line to the beltpack.
2. Turn down the beltpack’s incoming volume on each intercom
channel with the channel A and channel B volume-control
knobs.
3. Plug in a headset to the beltpack’s connector labeled
“headset.”
4. To talk on an intercom channel, press and hold the talk
button for the desired channel. Speak into the microphone in
your headset.
Note : If you tap the talk button twice in quick succession, the
talk button locks to the “on” setting (“latches”) for hands-free use.
Press the talk button again to unlatch it. RS-603R and
RS-623R models initially power up in RTS-mode, in which a
talk button latches with a single tap. You can change this setting
with onboard controls or with the V-Pack software. See the
chapter “Customizing Your Beltpack” later in this manual for
information on programming a beltpack.

OPERATING YOUR BELTPACK
COMPATIBILITY WITH TWO-WIRE (“TW”) INTERCOM SYSTEMS
Clear-Com designed the RS-603, RS-623, RS-603R, and RS-623R
series of beltpacks to operate with “TW” (two wire) systems. These
beltpacks have the appropriate audio levels and frequency response
curves for operating on a TW intercom line, as well as having such
TW features as AC call signaling and remote microphone shutoff.
The RS-603 and RS-623 models are shipped ready to operate on
Clear-Com TW intercom lines, while the RS-603R and RS-623R
models are shipped ready to operate on RTS-TW intercom lines.
However, using a beltpack’s onboard controls, you can easily
reprogram any of these models to work on the opposite system. For
example, you can program a Clear-Com TW-compatible beltpack to
operate on an RTS intercom line, and program an RTS-compatible
beltpack to operate on a Clear-Com TW intercom line.
For more information about programming a beltpack, see the chapter
“Customizing Your Beltpack.”

RS-603 AND RS-623 MODELS
All previous versions of Clear-Com TW beltpacks and stations work
compatibly with the RS-603 and RS-623 beltpacks. The RS-603
beltpack operates with a monaural headset, while the RS-623 beltpack
operates with a binaural headset.
RS-601 beltpack models are compatible with Clear-Com TW
products and can be mixed on an intercom channel with RS-603
series units that are operating in Clear-Com mode.
RS-603R AND RS-623R MODELS
The RS-603R and RS-623R beltpacks feature female rather than male
headset jacks. The RS-603 beltpack operates with a monaural headset,
while the RS-623R beltpack operates with a binaural headset.
The RS-623R beltpack features a 5-pin female headset jack. Although
this model’s headset jack is programmed for monaural operation, it is
capable of split-ear operation with a compatible headset. You can
program the beltpack to operate with a monaural headset using the
beltpack’s onboard controls or the V-Pack software.See the chapter
“Customizing Your Beltpack” for more information.

Call Buttons, Channels A and B
When you press a channel’s call button, a call signal is sent to all other
stations on that channel. Pressing the Call A button sends a call signal
on channel A. Pressing the Call B button sends a call signal on
channel B.
A channel’s call light glows red to indicate both outgoing and
incoming call signals on the channel.
Note: Depending on the type and length of cables attached to the beltpack,
crosstalk between cables may cause both channels to indicate a 20 kHz AC
call signal that is sent on only one channel.
5
Volume-Control Knob, Channel A
The volume-control knob for channel A adjusts the incoming volume
level (“listen level”) for that channel.
There is a limiter built into the beltpack circuitry to prevent incoming
volume from exceeding a safe level. You can suspend this limit with
the V-Pack software.
The volume A control knob also adjusts mic gain (either main or
auxiliary). Refer to “Customizing Your Beltpack” for more
information on adjusting outgoing volume.

Computer Connector
10
You can program your beltpack from a computer using the V-Pack™
programming software. To use this software you must first physically
connect the beltpack to a computer with Clear-Com’s VPC-1 cable or
its equivalent.
The VPC-1 cable has a tip-ring-sleeve 3.5 mm plug at one end for
connecting to the beltpack, and a DB-9F plug at the other end for
connecting to a computer’s serial port.
To connect the VPC-1 cable from your beltpack to a computer:
1. Plug the 3.5 mm plug at one end of the cable into the beltpack’s
3.5 mm jack located just under the setup button.
2. Plug the DB-9F plug on the other end of the cable into the DB-
9M serial port socket on a computer.
If your computer has only USB ports rather than a serial port, you
must purchase a USB-to-serial port adaptor.
Contact your dealer or the Clear-Com factory for information about
obtaining the beltpack programming kit, which contains the V-Pack
software, VPC-1 cable, and V-Pack manual. You can also find a PDF
of the V-Pack manual at www.clearcom.com.

To adjust the beltpack’s “sidetone,” or the level of one’s own voice in
the headset, insert a small flat-headed screwdriver into one of the two
holes labeled “sidetone” on the back of the beltpack, as shown in
Figure 4.
The upper control adjusts the sidetone for channel A. The lower
control adjusts the sidetone for channel B.
Turn the screwdriver until you can no longer hear any sidetone in the
headset. This is called the “null” setting.
When you turn the screwdriver again, either clockwise or
counterclockwise, the sidetone increases. Adjust the sidetone so that it
is somewhere in the mid-range of possible settings, at a level that feels
comfortable to you.
The need for an extreme sidetone setting to either limit could indicate
a problem with the overall intercom system, such as lack of
terminations or multiple terminations. A malfunctioning headset
could also be the cause. Do not force the sidetone adjustment control
past its stop points as this will damage it.
Note: The small raised dots next to the sidetone controls help you to
identify the correct control in darkened environments. The channel A
control has one raised dot adjacent to it. The channel B control has two
raised dots adjacent to it.

CONNECTING THE BELTPACK
A beltpack connects to the intercom line by connecting to a main
station, power supply, or another beltpack. You must also connect a
headset to the beltpack and, optionally, a computer for programming
beltpack options with the V-Pack software.
The following table lists the connectors for the RS-603 series of
beltpacks. Figure 5 illustrates the connectors for an RS-603 beltpack

Intercom Connector / Loop-Through Connector
Figure 1 illustrates the “intercom” and “loop-through” connectors on
an RS-603 beltpack. The beltpack connects to a main station, power
supply, or to other beltpacks with the connector labeled “intercom.”
The “loop-through” connector connects the beltpack to the intercom
line or to another beltpack (“looping through”).

The loop-though connector becomes a program-audio input
connector when you select that option with the slide switch located
directly next to the connector. See the section “Program-Input Select
Switch” below for more information.
Note: On the RS-603R and RS-623R models, the intercom and
loop-through connectors swap places, in the RTS style.

Program-Audio Volume Control
3
You can adjust the volume level of the program audio by rotating the
program audio volume control. If necessary, you can mute the
program audio by turning the knob all the way down.
The program audio is transformer isolated and accepts line level
signals in the –20 to +10 dBv range.
4
Auxiliary (“AUX”) Headphone
Clear-Com designed the auxiliary headset connector, labeled “AUX,”
for use with the CC-25 Ultra-Light headset. The beltpack’s circuitry is
designed to work with the CC-25 headset to produce excellent quality
sound.
While certain types of mobile-phone style headsets will fit the 2.5 mm
AUX jack, using these headsets degrades system performance due to
reduced audio bandwidth and reduced noise rejection at the
microphone. You can use such mobile-phone style headsets more
reliably with listen-only applications.
The AUX connector provides bias voltage for electret microphones.
With V-Pack, you can also program this connector for use with
dynamic microphones.
Note: Using multiple mobile-phone style headsets in a system could
adversely affect nulling, crosstalk, and overall system performance.
RS-603/623/R BELTPACKS
21
5
Headset Connector
You connect a headset to the beltpack at the connector labeled
“headset.” The RS-603 series beltpacks have varying types of headset
connectors. See Table 1 for a list by model number.
The headset connector is always active and has priority if a second
headset is connected to the auxiliary (“AUX”) connector. Generally
you should connect only one headset at a time to a beltpack.
All RS-603 series models provide power to an electret microphone.
The microphone’s gain automatically adjusts to an electret
microphone. See “Specifications” for impedance requirements.
Program-Audio Input Select Switch
6
To transform the “loop-through” connector to a program-audio input
connector, move the slide switch toward the headset connector, in the
direction labeled on the beltpack as “PGM.”
Note: Placing the switch in the “program” (PGM) position while the jack
is still connected to the intercom channel causes the beltpack to lose power
and the channel to short out.
When you do so, the loop-through connector becomes a program
audio input connector, disabling the loop-through function of the
connector.
The program input is transformer isolated and accepts line level
signals in the –20 to +10 dBV range.
2 2
R S - 6 0 3 / 6 2 3 / R B E L T P A C K S
To adjust the program audio volume, rotate the knob located on the
bottom panel of the beltpack.
To restore the connector to its “loop-through” function, slide the
switch back towards the “loop-through” connector, in the direction
labeled on the beltpack as “intercom.”
Note: In some instances, connecting a source of program audio may cause
a hum in the system. To remedy this, remove the internal jumper from
pins 1 and 2 of P2 and connect the jumper to pin 2 only. This removes
the ground and leaves only a balanced, transformer-isolated connection.
To gain access to the jumper, remove the beltpack’s back cover by removing
the four screws.

CUSTOMIZING YOUR BELTPACK
You can customize an RS-600 series beltpack for quick adaptation to
the needs of any working environment. There are two methods for
customizing your beltpack’s settings:
• Using a beltpack’s onboard controls
• Using the V-Pack programming software
This manual describes programming a beltpack with the onboard
controls, and only briefly describes V-Pack. The V-Pack programming
software has its own manual, which you can view and download at
www.clearcom.com.
Note: You may also refer to the printed guide on the back of the beltpack for
quick instructions on setting up the beltpack with the onboard controls.
V-PACK SOFTWARE
The V-Pack programmming software gives you access to the full range
of options for customizing your beltpack. For example, you can
program a call signal to appear as a steady or flashing light, a bright or
dim light, or a tone. You can activate and adjust a noise gate. You can
set a minimum headset level.
A unique V-Pack feature is to create one custom setup and quickly
transfer it to several beltpacks with the “beltpack cloning” feature. This
RS-603/623/R BELTPACKS
27
feature is useful for programming many beltpacks with the same
settings. And V-Pack includes many more features you can program
for your beltpack.
To operate the V-Pack software, you must first install it on a computer,
then connect the VPC-1 cable to both a beltpack and to your
computer.
For more detailed instructions on using the software, see the V-Pack
manual or on-line help files. You can access the manual from the
Clear-Com Web site. A VPC-1 installation kit, which includes a
factory CD containing the V-Pack software, a computer cable, and a
printed V-Pack manual is available for purchase through your dealer
or directly from Clear-Com.
ONBOARD PROGRAMMING
With onboard programming, you customize the operation of your
beltpack using the controls on the beltpack itself.
When you receive your beltpack, it already contains the default
settings that will meet the needs of most users. You do not need to
program it unless you want to.
However, if you wish to change the settings to better meet your needs,
you can do so with onboard programming. The beltpack remembers
your new settings until you change them again.
28
RS-603/623/R BELTPACKS
SETTINGS YOU CAN CUSTOMIZE
Table 1 shows the beltpack functions you can customize with onboard
controls. Note than each function is assigned a number, which you will
refer to for programming.

Function 8 Channel exclusive on or off A or B
Function 9 Mono (binaural models only) on or off Both A and B
Function A Adjust Microphone Gain variable Both A and B
Function L Locks out onboard access on or off Both A and B
Table 1: Functions You Can Edit With Onboard Controls
Before you program the beltpack with the onboard controls, the
beltpack must be connected to an intercom line and receiving power,
and must not be connected to a computer.
You can program most functions to operate on channel A, channel B,
or both. However, some functions affect both channels. Table 1 shows
if a function affects one or both channels.

Mode Select, Function 1
A “mode” is one complete “package” of settings for a beltpack. Each
beltpack’s memory holds four modes. You can easily select and activate

MAINTENANCE
GENERAL USAGE NOTES
Cabling choices can greatly impact the performance of an intercom
system. Length, gauge, and shield quality, as well as routing, must all
be considered. For two-pair cable, crosstalk performance is affected
both by length and DC resistance of the shield (the lower the better).
The quality of the headset cable can affect crosstalk, particularly in
large systems.
Note: For more information on installing a party-line system, see the
Party-Line Installation Manual.
A beltpack’s headphone amplifier accommodates impedances from 50
to 2000 ohms. The mic preamplifier accommodates impedances
from 50 to 1000 ohms. Output level is more critical to optimal
performance than the impedance. Higher impedances may require
more microphone gain, thereby raising the noise floor.
Note: If you install an RS-603 series betlpack with standard (non-TW)
Clear-Com equipment on a non-TW line, channel B functions, but
channel A does not.
To avoid oscillation from the unterminated A channel, you can use the
beltpack’s onboard controls to select one-channel operation (“channel
exclusive,” function 7).
