Introduction
Introduction
The Venue Wideband receiver is a modular rack mount
design for use with a wide variety of transmitters from
Lectrosonics and other manufacturers. Designed for
maximum versatility and performance, the wideband
design offers the flexibility needed in today’s changing
and increasingly congested RF environments.
A Venue receiver is a “system” that consists of a master
unit and up to six receiver modules. Two different types
of receiver modules are available. The standard module
(VRS) is an excellent choice for fixed installations where
fairly clear RF spectrum is available. The tracking module (VRT) is a more costly alternative, but its tracking
front-end makes it the better choice for use in congested RF environments. VRpanel software is included to
simplify setup and monitoring.

Controls and Functions
Front Panel
POWER Switch
The Venue receiver master unit (VRM) serves as a
“host assembly” for up to six receiver modules. The
standard module (VRS) and tracking module (VRT) can
be mixed and matched in the assembly in any combination to suit the needs of various applications.
The VRM front panel provides an LCD for system setup,
monitoring and troubleshooting. During normal operation, the LCD shows RF and audio levels, diversity
status, pilot tone status (where applicable) and transmitter battery status (in certain modes) for all six receivers
at the same time. Individual screens for each receiver
provide additional information and adjustments.
A built-in analyzer scans the tunable spectrum of the
receiver to assist in finding clear operating frequencies.
The spectrum scan data is presented in a graphical
format on the LCD.

The LEVEL control is used to adjust the output level
of the front panel PHONES jack for individual channel monitoring. It does not affect the output levels at
the rear panel XLR jacks. Only the audio from a single
receiver (or a diversity pair) selected via the Receiver
Select Buttons will be present at this jack.
The PHONES jack can also used as an audio output for
recording when using the Walk Test Recorder.

The rear panel provides six balanced XLR audio outputs, antenna inputs, “loop thru” antenna outputs from
an internal multicoupler, a power jack with a locking
connector, plus USB and RS-232 serial ports for setup
and control.
Receiver Modules
Up to six receiver modules can be installed in each
Venue receiver rack mount chassis. Spring tensioned
clips retain the receiver modules to maintain secure
connections with the host assembly.
XLR Audio Output Jacks
Six balanced XLR audio output jacks connect the Venue
receiver to external equipment. By default, pin 2 is audio pos (+). The polarity of each output can be reversed
in the LCD setup menus or with the software.
Power Input Jack
The receiver is powered from +10 VDC to +18 VDC,
with the center pin of the connector positive (+). The
input is diode protected to prevent damage if the power
is accidentally applied with reversed polarity.
RS-232 Port
A serial RS-232 interface is provided for setup and
control of the Venue System from computers or other
devices using industry standard RS-232 communication
links.
Antenna Input Jacks
The two outermost BNC connectors are provided for
use with right-angle whip antennas, cables from remote
antennas, or cables from another Venue receiver. DC
voltage can be supplied on these connectors from an
internal source to power remote RF amplifiers. The
power is enabled with jumpers on the circuit board. See
the section on Antenna Use and Placement for details.
Multicoupler Output Jacks
The built-in antenna multicoupler provides RF distribution for the six receiver modules and a “loop thru” output
at the same level to deliver the RF signal to another
Venue receiver. The second receiver can then feed a
third receiver and so on, to create a “stack” that operates with a single pair of antennas. The result is very
efficient use of rack space and a cost savings by not
having to purchase a separate antenna multicoupler.
Note: Venue receivers with a 50 MHz bandwidth
must be on the same frequency block to use the
antenna loop through.
USB Port
Standard USB Version 1.1 port for setup and control of
the receiver from computer systems using Windows®
2000, XP or VistaTM operating systems.

VR Field Wideband Receiver
Initial Startup
When the Venue receiver is first powered up the LCD
will show the firmware revision and the tuning range of
the host assembly. The wideband version of the VRM
covers the entire 230 MHz bandwidth of frequency
blocks 21 through 29.
As the boot sequence continues, the display will switch
to an overview of all six receiver channels. In this example, six receiver modules are installed but no transmitters are turned on. In this case the “P” will be blinking
since no pilot tone is detected.
The wideband Venue receiver is different than the 50
MHz version in that the receiver modules are detected
through a manual process rather than automatically at
boot up. Press the MENU/SELECT control and rotate it
to select “Detect” on the menu.
The display then switches to the overview of all six
channels.
Any slot that is not occupied by a module will leave a
blank space in the overview display.
If a module in any position has been removed, changed
or added since the last use, the LCD will flash a message advising that the Detect process needs to be run
again.
In normal operation with all six channels running, the
overview display will include:
• Audiolevel
• RFlevel
• Diversityantennaphaseactivity
• Pilottonestatus
• Transmitterbatterystatus
Audio level
Pilot tone status
Press the MENU/SELECT control to launch the detection process.
It takes about 45 seconds to detect all the modules and
update the memory in the host assembly. Once completed, the LCD will briefly display the results showing
the frequencies of the installed modules.
If a slot is not occupied by a module, the display will
place an “X” in that position.

Description
Selecting the Noise Reduction Mode
When the Compat Mode is set to Digital Hybrid, three
settings are available that affect the high frequency
audio content and noise:
• NORMAL(factory default) applies a moderate
amount of noise reduction, dramatically reducing
hiss with virtually no discernible side effects.
• FULL applies more aggressive noise reduction with
transparency superior to the noise reduction system
used for many years in the earlier Lectrosonics
wide deviation analog systems.
• OFF applies no noise reduction for complete transparency.

Navigate to the SmartNR setup screen.
LECTROSONICS, INC.
Digital Hybrid Wireless™ Modular Receiver System
In this mode the signals from both antennas are combined into a single receiver module, with the phase of
one of them inverted back and forth so that they always
add to one another. The process reduces dropouts and
provides a stronger signal than a single antenna.
Select the receiver module with Receiver Select Button
and rotate the MENU/SELECT control to the desired
mode. Listen to the audio signal as you rotate the knob
and select the mode that best fits the situation.
Note: If the selected Receiver Module is part of
a ratio or frequency diversity pair, the mode will
automatically be set for both receiver modules in
the pair.
When any Compat Mode other than Dig. Hybrid is selected, FIXED will automatically be selected.
In this example, receiver modules 4, 5 and 6 are set to
the FIXED mode with no adjustment available.
Selecting Diversity Modes
Navigate to the DivMode setup screen.
Ratio Diversity (OptiBlend
TM
)
Ratio diversity uses two adjacent receiver modules to
pick up a single transmitter. The audio outputs of the
modules are blended (mixed) together, using more or
less audio from each module based upon which module
has the stronger RF signal.
Ratio diversity anticipates dropouts before they occur,
rather than waiting until the RF signal level is very weak
and on the verge of noise or dropout. The comparison
of the RF signal levels in the modules begins when the
RF level is still high, so the circuit can blend in more
audio from the module with the stronger signal before
the signal decays enough to cause noise.
The blending action is smooth and seamless to avoid
any audible artifacts that can occur with abrupt switching. Most of the time both receiver modules have good
signals, so the audio is blended equally, which improves
the signal to noise ratio by 3 dB.
The blended audio appears at the rear panel XLR outputs of both modules.
Three diversity reception modes are available:
• Switched Diversity uses one receiver module per
audio channel.
• Ratio Diversity (OptiBlendTM) uses two receiver
modules per audio channel.
• Frequency Diversity uses two receiver modules
and two transmitters per audio channel.
Press the Receiver Select Buttons to enter the setup
screens for the receiver modules.
Switched Diversity
Frequency Diversity
Frequency Diversity differs from the other two diversity
modes in that it uses two receiver modules and two
transmitters operating on different frequencies. The purpose of this mode is to have redundancy in the system
for critical productions, such as live television, to guard
against failures caused by dead batteries and multipath
dropouts. The blending process to combine the audio
from the receiver modules is the same as that used for
OptiBlend ratio diversity.
Frequency Diversity requires that the levels of the two
audio channels to be closely matched to avoid audible level changes as the blending action takes place.
In order for this blending to work properly, a special
test mode helps to get the transmitter levels exactly
matched. The test mode is automatically activated when
the DivMode Setup Screen is active and Frequency
Diversity is selected, as shown in the LCD photo above.
Rio Rancho, NM, USA
13
VR Field Wideband Receiver
Note: In Frequency Diversity mode, both
transmitters must be the same type (usually the
same model). The microphones must also be
placed very close together to minimize comb
filtering.
To prepare for operation in the Frequency Diversity
mode, make the following adjustments:
1. Set up the transmitters according to their instructions. Plug a set of headphones into the front panel
PHONES jack to monitor the blended output. You
can also monitor the output from the rear panel
XLR jack for either module in the pair.
2. While listening to the blended output, adjust the
gain control on one of the transmitters so that the
audio loudness drops way down (nulls) as the two
channels cancel each other. If the output does not
null, then reset the transmitter input gain control
back to where it was and press the Function button
on the front panel next to the word INVT on the
LCD. This will invert the phase of the audio on the
second module so it will null properly.
NORMAL MODE is the standard Lectrosonics mode
with 256 frequencies in 100 kHz steps. A unique pilot
tone is present for each frequency.
FINE MODE allows tuning to 1024 frequencies in
25 kHz steps for compatibility with older and nonLectrosonics transmitters. Pilot tone frequency is set to
the next lower even 100kHz frequency. For example,
650.000, 650.025, 650.050 and 650.075 all use the
same pilot tone frequency.
INVT shown in Off Position
Depending on how microphones are wired and
other vagaries, either position of the INVT toggle
switch might achieve the null. Keep toggling the
switch until the null is found, adjust the level for the
deepest null. Be sure to press INVT one more
time to put the audio from the two channels
back in phase for normal operation.
Selecting the Tuning Mode
Pre-coordinated tuning groups are stored in memory to
simplify frequency coordination. The groups are labeled
GROUP a, b, c and d on the LCD, with eight frequencies stored in each one. Refer to the section near the
back of this manual entitled Pre-coordinated Frequencies for details on compatibility and using these groups.
CUSTOM MODE is a special mode used to store up to
50 frequencies per block in 25 kHz steps. Frequencies
are stored in memory in a “table” with positions numbered 0 through 49. The pilot tone frequency is defined
by the position of each frequency in the table.
The Receiver Detail window will indicate the selected
mode and frequency information. In the FINE mode
transmitter switch settings will be shown when the
frequency is on an even 100 kHz step. In the CUSTOM
mode the position of the frequency in the table of 50
stored in memory will be shown.

Finding Clear Frequencies with SmartTune
SmartTune simplifies setup by scanning the tuning
range of the receiver and automatically setting a receiver module to a clear frequency. A receiver module
is selected, a scan is completed and the frequency is
set for that module. A prompt appears, reminding you to
turn on a transmitter on the newly selected frequency,
and the procedure continues until all modules have
been tuned to clear frequencies.
NOTE: SmartTune is only available using the LCD
and front panel controls. It is not implemented in
the software.
1. Navigate to the SmrtTun setup screen and press
the MENU/SELECT control.
In most cases the system will be ready to use after
SmartTune has been run on all modules, however, it’s
a good idea to perform a system checkout to verify
the compatibility of the frequencies selected. Refer to
the section entitled Diagnostics near the back of this
manual for details.
Finding Clear Channels with Tuning
Groups a through d
Groups “a” though “d” contain 8 frequencies each that
can be used together in certain combinations. In brief,
“a” and “b” are compatible with each and “c” and “d”
are compatible with each. Other combinations require
testing. Refer to the section entitled Pre-coordinated
Frequencies for details on using these groups.
To use groups a through d, complete the following
steps:
1. Navigate to the Tuning setup screen.
2. Press the Receiver Select Button for the module
you wish to tune and scanning will begin.
When the full spectrum has been scanned, the cur-
sor will stop moving and blink briefly on the newly
selected frequency briefly.
3. The display will then switch back to the receiver selection screen and ask if you want to tune another
module.
4. If you select Yes the display will remind you to turn
on the transmitter for the receiver you just tuned.
2. Select each module in turn with the Receiver Select
Buttons and select the desired tuning group. Then
return to the overview screen.
3. Turn transmitters off. From the overview screen,
open the receiver detail screen for each module
and rotate the MENU/SELECT control to select a
frequency where no RF signal is indicated.
Finding Clear Channels
Using Full Spectrum Scan
In crowded RF environments, it may not be possible to
find enough clear channels using a Tuning Group. The
internal spectrum scanner can then be used to find
clear channels manually across the entire tuning range
of the receiver in 100 kHz steps.
1. Turn off all transmitters and set all receiver modules
to the NORMAL tuning mode (not a tuning group).
2. Select Scan from the TopMenu and press the
MENU/SELECT control.
When the transmitter is turned on and detected, the
display will return to receiver selection (Step 2) and
prompt you to select the next receiver.
5, Repeat steps 2 through 4 for all receiver modules
that will be used.

Adjusting Audio Output Levels
The audio output levels at the rear panel XLR jacks are
software controlled. (The front panel LEVEL knob affects the PHONES output only.)
The optimum output level will provide the highest level
signal possible without overloading the input to external
equipment or driving a subsequent stage in the signal
chain into limiting or compression. Ideally, the gain
needed to drive the rest of the signal chain should be
present at the receiver outputs, with each successive
stage in other equipment set to unity (no gain or loss).
Tone On/Off Indicator
(Shown in Off position.)
3. Use the Tone Generator to adjust other equipment
to match the output level from the receiver with full
modulation of the transmitter. Press the Function
Button to start the tone.
The indicator will reverse to a dark background
with light letters when the tone is delivered to the
selected output. Rotate the MENU/SELECT control
to set the desired level.
WARNING: The 1 kHz reference tone is
equivalent to full modulation at the transmitter.
It is LOUD.
The test tone level is always at the 0dB reference level
(full modulation of the wireless system), which is the
level at which the first red “limit” light comes on at the
transmitter.
The highest level that the equipment downstream will
ever see before the receiver clips is 4.5 dB higher than
the test tone. Note that this is output headroom. Over
the entire 30+ dB range of the limiter in a Lectrosonics
transmitter, the output at the receiver goes up only 4.5
dB or less.
NOTE: The tone is a sine wave with about 1%
distortion

Selecting Audio Phase
Microphone wiring and other vagaries can alter the
phase of an audio signal. To compensate for this, the
phase of the audio output of each receiver module can
be inverted.
1. Navigate to the Phase setup screen.
2. Select each receiver module with the Receiver
Select Button and adjust the phase with the MENU/SELECT control.
Selecting Transmitter Battery Status
Monitoring Mode
The receiver will monitor the status of the batteries in
the transmitters and display it when used with certain
transmitters, such as Lectrosonics 200 Series and Digital Hybrid models. The type of battery being used in the
transmitter must be defined in the TxBatt setup screen.
NOTE: The Compat Mode (compatibility mode)
set for each receiver module will determine which
battery monitoring methods are available
The TxBatt setup screen allows you to select the exact
battery being used in the transmitter to provide more
accurate battery level monitoring. Alkaline, lithium and
rechargeable AA and 9V types are commonly used.
The voltage declines gradually over the life of alkaline
and lithium types, so the voltage can be estimated and
displayed by the receiver. Rechargeable types, on the
other hand, maintain almost constant voltage as they
discharge, so a timer is provided in the receiver to
track operating time and anticipate the need for battery
changes.
1. Navigate to the TxBatt setup screen.
2. Select each receiver module with the Receiver
Select Button and set the battery type being used in
the corresponding transmitter.
9V ALK Transmitter uses a 9V alkaline battery.
Monitor voltage with battery icon in main
window.
9V LTH Transmitter uses a 9V lithium battery. Moni-
tor voltage with battery icon in main window.
9V TIM Transmitter uses a 9V battery. Display its
voltage normally in the battery level window
but monitor its status with the battery timer
in the main window.
AA ALK Transmitter uses a AA alkaline battery.
Monitor voltage with battery icon in main
window.
AA LTH Transmitter uses a AA lithium battery. Moni-
tor voltage with battery icon in main window.
AA TIM Transmitter uses an AA battery. Display its
voltage normally in the battery level window
but monitor its status with the battery timer
in the main window.
The 9V TIM and AA TIM settings are most useful for rechargeable batteries, all or most of which do not exhibit
reliably identifiable voltage drops as they discharge.
In compatibility modes other than 400 Series and 200
Series, no battery telemetry information is available so
the TXBAT setup screen offers only two choices:
NOTIMER Display no transmitter battery status in the
main window.
TIMER Monitor the transmitter battery status with
the battery timer in the main window.
If the selected receiver module is part of a ratio
diversity pair, the battery type will be automatically
set for both units in the pair. If the selected receiver
module is part of a frequency diversity pair, the
battery type is set independently for each receiver
in the pair since there are two transmitters in use.
3. When either the AA TIM or 9V TIM (timer) mode
is selected, press the Function Button to reset
(“ZERO”) the timer.

Antenna Use and Placement
An tenn a An tenn a
The Venue System is designed for rack mounting.
Although it can be operated with two whip antennas, it
is best to use remote antennas such as the SNA600 or
ALP Series for optimum reception. Position the remote
antennas at least three or four feet apart and not within
three or four feet of large metal surfaces. If this is not
possible, try to position the antennas so that they are as
far away from the metal surface as is practical. It is also
good to position them so that there is a direct “line of
sight” between the transmitter and the receiver antennas.
In situations where the operating range is less than
about 100 feet, the antenna positioning is much less
critical. The length and type of cabling between antennas and the system, however, is critical. Long cable
runs can experience serious signal loss. Lectrosonics
offers in-line RF amplifiers suitable for compensating for
this signal loss. Contact your dealer or the factory for
more information.
A wireless transmitter sends a radio signal out in all
directions. This signal will often bounce off nearby walls,
ceilings, etc. and a strong reflection can arrive at the
Digital Hybrid Wireless™ Modular Receiver System
receiver’s antennas along with the direct signal. If the
direct and reflected signals are out of phase with each
other and similar in strength, a cancellation or “dropout” may occur. A dropout can sound like audible noise
(hiss, swishing or a “shhht” sound), or in severe cases,
may result in a complete loss of both the carrier and the
sound. Moving the transmitter even a few inches can
change the sound of the dropout, or may even eliminate
it. A dropout situation also may be either better or worse
as a crowd fills or leaves the room.
The Venue System offers several different diversity
reception methods which can overcome most dropout
problems. In the event, however, that you do encounter
a dropout problem, first try moving one of the remote
antennas at least three or four feet from its current
location. If dropouts are still a problem, try moving the
antennas to entirely different locations.
Lectrosonics transmitters radiate power very efficiently,
and the receivers are very sensitive, which reduces
dropouts to an insignificant level. If, however, you do encounter dropouts frequently, call the factory or consult
your dealer. There is probably a simple solution.
Powering Remote RF Amplifiers
UFM230 UFM230
DC Power to UFM230 DC Power to UFM230
Remote antennas can be placed
at a distance from the VRM to
optimize reception. To overcome
loss in long coaxial cable runs, a
Lectrosonics UFM Series inline
RF filter/amp should be positioned
at the far end of the coaxial cable,
close to the antenna.
With the amplifier in this position, gain is applied ahead
of the loss to maximize the signal to noise ratio of the
antenna system.
Power for the UFM amplifier can be supplied by the
Venue receiver through the coaxial cable by setting
jumpers on the main PC board toward the center of the
board as shown. Disconnect power and then remove
the top cover for access to the jumpers.

NOTE: It is best practice to enable this DC power ONLY
when a UFM remote amplifier is used. Some antennas may present a short to the power supply. While the
power supply is fused and it is unlikely that damage
would occur, it is always best to disable the DC when it
is not in use.

Pre-coordinated Frequencies
Interference from IM (intermodulation) is a potential
problem in all multi-channel wireless systems, so proper
frequency coordination is always required to avoid
noise, range and dropout problems. Your options to accomplish this include:
• Usingthepre-coordinatedfrequencygroups
• Performingasystemcheckout
(See Multi-channel System Checkout)
• CallingLectrosonicsforassistance
Compatible Frequency Table
Groupings of compatible frequencies have been created to minimize intermodulation problems in multiple
channel wireless systems. The frequencies can be used
with Digital Hybrid and analog Lectrosonics wireless
equipment. Compatibility with other brands is likely, but
not guaranteed by Lectrosonics.
The table provides two different sets of pre-coordinated
frequencies for frequency blocks 470 through 29. The
table is constructed to create a visual pattern of compatible frequencies to make it easier to use. The frequencies are stored in memory in various products and
included in the VRpanel software.
Pre-coordinated frequencies are arranged
in four groups as shown
at right.
The uppermost eight
frequencies comprise
Grp a, the eight just
below them comprise
Grp b, and so on.

Diagnostics
Multi-channel System Checkout
Interference can result from a wide variety of sources
including TV station signals, other wireless equipment
in use nearby, or from intermodulation within a multichannel wireless system itself. Regardless of how the
frequencies were coordinated, a final checkout procedure is always a good idea.
Scanning with the RF spectrum analyzer built into the
Venue system will identify external RF signals, but
it does not address the compatibility of the selected
frequencies.
The pre-coordinated frequencies on the chart on the
previous pages address in-system intermodulation,
but obviously cannot take into account RF signals from
external sources that may be present in the location
where the system will be operating.
In some cases, you can run the scanner to find clear TV
channels, then find enough pre-coordinated frequencies
in the tuning groups (Grp a through Grp d) to operate
on the clear TV channels. Even so, it is still a good idea
to go through the check out procedure because you
can encounter interference from other wireless, IFB and
intercom systems when you get to the production or
installation site.
1. Set up the system for testing.
Place antennas in the position in which they will be
used and connect to the receivers. Place transmitters about 3 to 5 feet apart, about 25 to 30 feet from
the receiver antennas. If possible, have all other
equipment on the set, stage or location turned on
as well, especially any mixing or recording equipment that will be used with the wireless system.
2. Set all receivers on clear channels.
Turn on all receivers, but leave the transmitters off.
Observe at the RF signal strength indicator for each
receiver module. If a signal is present, change the
frequency to a clear channel where no signal is
indicated. If a completely clear channel cannot be
found, select the frequency with the lowest RF level
indication. Once all receiver modules are on clear
channels, go to step 3.
4. Turn each transmitter off one at a time.
With all transmitters and receivers turned on, turn
each transmitter off one at a time, in turn, and look
at the RF level indicator on the matching receiver
module. The RF level should disappear or drop to a
very low level. If it does not, change frequency on
that receiver and transmitter and try it again. When
a clear frequency is found, turn the transmitter on
and move on to the next channel.
IMPORTANT: Any time a frequency is changed on
any of the systems in use, you must start at the
beginning and go through this procedure again for
all systems. With a little practice, you will be able
to do this quickly and save yourself some “multichannel grief.”
Pilot Tone Bypass
Some wireless equipment uses a supersonic “pilot tone”
to control the squelch (audio mute) of a receiver module
to keep it silent until a valid signal is received. When a
signal with the correct pilot tone is received, the squelch
opens and audio is delivered to the output. Pilot tone
squelch control also eliminates transients (clicks and
pops) when transmitters are turned on and off. Pilot
tone is supported in the Digital Hybrid compatibility
modes for those systems that use it.
Pilot tone control can be bypassed as a diagnostic tool.
Bypass opens the audio output of the receiver unconditionally, allowing you to listen to any signals entering the
receiver to help identify their source. Pilot tone bypass
will also allow you to use a transmitter that has a defective pilot tone circuit.
CAUTION: When pilot tone is bypassed and
the transmitter is turned off, excessive noise
will be present. Turn the audio level down
before bypassing pilot tone.
Navigate to the PilotBP setup screen.
3. Turn each transmitter on one at a time.
Start with all transmitters turned off. As you turn on
each one, look at the matching receiver to verify a
strong RF signal is received. Then, look at the other
receivers and see if one of them is also picking up
the signal. Only the matching receiver should indicate a signal. Change frequencies on either system
slightly until all channels pass this test, then check
again to see that all channels are still clear as done
in step 2.

Select the receiver module with the Receiver Select
Button and rotate the MENU/SELECT control to select
BYPASS. In this example, the pilot tone for receiver
module 1 is set to BYPASS (BYP) and the others are
set to NORMAL (NOR).

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting
cables and then go through the TROUBLESHOOTING section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection,
send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the
factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are
no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
