information see CMN-91 Service and Support (on page 24).
Operator’s Safety Summary
WARNING
These instructions are for use by qualified personnel only. To reduce the risk of electric
shock, do not perform this installation or any servicing unless you are qualified to do so.
Refer all servicing to qualified service personnel.
Ensuring Safety
The unit should not be exposed to dripping or splashing, and no objects filled with liquids, such as
vases, shall be placed on the unit.
When the unit is to be permanently cabled, connect the protective ground conductor before making
any other connections.
Operate built in units only when they are properly fitted into the system.
For permanently cabled units without built in fuses, automatic switches, or similar protective
facilities, the AC supply line must be fitted with fuses rated to the units.
Before switching on the unit, ensure that the operating voltage set at the unit matches the line
voltage, if appropriate. If a different operating voltage is to be set, use a fuse with the appropriate
rating. Refer to the Installation Instructions.
Units of Protection Class I with an AC supply cable and plug that can be disconnected must be
operated only from a power socket with protective ground contact:
Do not use an extension cable–it can render the protective ground connection ineffective.
Do not intentionally interrupt the protective ground conductor.
Do not break the protective ground conductor inside or outside the unit or loosen the protective
ground connection; such actions can cause the unit to become electrically hazardous.
Before opening the unit, isolate it from the AC supply. Then, ensure that
Adjustments, part replacements, maintenance, and repairs are carried out by qualified
personnel only.
Safety regulations and rules are observed to prevent accidents.
Only original parts are used to replace parts relevant to safety (for example, the power on/off
switches, power transformers, and fuses).
Replaceable fuses can be hazardous when live. Before replacing a fuse, disconnect the AC power
source.
Use caution when cleaning the equipment; isopropyl alcohol or similar solvents can damage or
remove the labels.
Observe any additional safety instructions specified in this manual.

Explanation of Symbols
These symbols may appear on Imagine Communications equipment:
Figure 1: Safety Symbols that may Appear
This product manual uses the following safety terms and symbols to identify certain conditions or
practices.
WARNING
Identifies conditions or practices that can result in personal injury or loss of life —high voltage
is present. Uninsulated dangerous voltage within the product’s enclosure may be sufficient to
constitute a risk of electric shock to persons.
CAUTION
Identifies conditions or practices that can result in damage to the equipment or other property.
Important operating and maintenance (servicing) instructions are included in the literature
accompanying the product.
Certification Labels and Symbol Locations
On Imagine Communications equipment, certification labels and symbols are located on the back panel,
rear chassis sides, or bottom rear of the chassis. On smaller space-restricted units, most labels and
symbols can be found on the bottom rear of the chassis.
Directives and Compliances
This section provides information concerning Imagine Communications compliance with EU Directive
2002/95/EC and EU Directive 2002/96/EC.

CMN-91
Installation and Operation Manual About This Manual

Restriction on Hazardous Substances (RoHS) Directive
Directive 2002 / 95 / EC —commonly known as the European Union (EU) Restriction on Hazardous
Substances (RoHS) —sets limits on the use of certain substances found in electrical and electronic
equipment. The intent of this legislation is to reduce the amount of hazardous chemicals that may leach
out of landfill sites or otherwise contaminate the environment during end-of-life recycling. The
Directive, which took effect on July 1, 2006, refers to the following hazardous substances:
Lead (Pb)
Mercury (Hg)
Cadmium (Cd)
Hexavalent Chromium (Cr-V1)
Polybrominated Biphenyls (PBB)
Polybrominated Diphenyl Ethers (PBDE)
In accordance with this EU Directive, products sold in the European Union will be fully RoHS-compliant
and "lead-free." Spare parts supplied for the repair and upgrade of equipment sold before July 1, 2006
are exempt from the legislation. Equipment that complies with the EU directive will be marked with a
RoHS-compliant symbol, as shown below.
Figure 2: RoHS Compliance Symbol
Waste from Electrical and Electronic Equipment (WEEE)
Directive
The European Union (EU) Directive 2002 / 96 / EC on Waste from Electrical and Electronic Equipment
(WEEE) deals with the collection, treatment, recovery, and recycling of electrical and electronic waste
products. The objective of the WEEE Directive is to assign the responsibility for the disposal of
associated hazardous waste to either the producers or users of these products. As of August 13, 2005,
producers or users are required to recycle electrical and electronic equipment at end of its useful life,
and must not dispose of the equipment in landfills or by using other unapproved methods. (Some EU
member states may have different deadlines.)

In accordance with this EU Directive, companies selling electric or electronic devices in the EU will affix
labels indicating that such products must be properly recycled. Contact your local Sales representative
for information on returning these products for recycling. Equipment that complies with the EU directive
will be marked with a WEEE-compliant symbol, as shown below.

Introduction
The CMN-91 compact video and audio monitoring unit is the most advanced, versatile, and intuitive
monitoring instrument available today. The CMN-91 is available for HD-SDI/SD-SDI (which can be
upgraded to 3 Gb/s capability in two SDI inputs). With 100% digital signal processing technology;
integral, high-resolution, XGA TFT color LCD display; the CMN-91 provides an accurate and stable user
customizable display of waveform, vector, gamut, audio, picture, relative timing, and alarm status
functions in full-screen views. In addition, the CMN-91 provides overlay display capabilities for vector,
waveform, and picture-in-picture (PIP) functions. Quick setup and parameter changes are possible with
direct access to display functions and screen location, 99 presets, context-sensitive shortcut menus, and
an intuitive navigation system.
The CMN-91 features extensive audio and video alarm capabilities, including peak level reporting. All
real-time signal alarms have user adjustable limits, time stamps from LTC or DVITC and an internal clock.
Remote interfaces include 10/100Base-T Ethernet and plug and-play USB port (supporting storage and
recall of presets and frame-capture transfer). The CMN-91 instruments are digital instruments with all-
digital architecture; therefore, no periodic calibration is required. When a CMN-91 unit is equipped with
the optional battery mount, a user-supplied lithium ion battery can be used to maintain power in the
field.
The CMN-91 seamlessly integrates into any broadcast, post-production, camera maintenance, satellite
or cable facility, and is the ultimate choice for quality control, troubleshooting, or compliance checking
applications.
