Keep at least one set of original packaging, in the event that you need to return a product
for servicing. If the original packaging is not available, you can purchase replacement
packaging at a modest cost or supply your own packaging as long as it meets the following
criteria:
Withstands the weight of the product
Holds the product rigid within the packaging
Leaves at least two inches of space between the product and the container
Protects the corners of the product
Ship products back to us for servicing prepaid and, if possible, in the original packaging
material. If the product is still within the warranty period, we will return the product prepaid
after servicing. For more information see LLM-1770 Service and Support on page 12.
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
If this equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
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.

LLM-1770
Installation and Operation Manual 5
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 Harris Broadcast equipment:
Figure P-1 Safety Symbols Appearing on Harris Broadcast Equipment
This product manual uses the following safety terms and symbols to identify certain
conditions or practices.
Table P-4 Safety Terms and Symbols Appearing in the Product Manual
Symbol Description
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 Harris Broadcast 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 Harris Broadcast compliance with EU Directive
2002/95/EC and EU Directive 2002/96/EC.
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 in
Figure P-2.
Figure P-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 in Figure P-3.

1Introduction
The Videotek® LLM-1770 loudness logger and monitor is a compact audio monitoring tool
that makes it easy to confirm compliance with the latest loudness requirements. Loudness
and true peak measurements are made to the ITU-R BS.1770 standard with five times
oversampling.
Included settings match EBU R 128, ARIB TR-B32, and ATSC A/85 recommendations.
Internal memory stores five days of loudness and alarm data. Logs can be exported via
Ethernet or USB. Remote control and monitoring can be performed from any web browser.
The LLM-1770 comes with four AES inputs and has options for Dolby decode and SDI
embedded from SD, HD or 3 Gb/s sources. There is a headphone jack for local confidence
monitoring. A standard LLM-1770 with the Dolby decode option installed is considered an
LLM-1770-D.
The LLM-1770 features audio alarm capabilities, including peak audio reporting. Real-time
signal alarms have user adjustable limits. Remote interfaces include 10/100Base-T Ethernet
and plug and play USB port (supporting export of log and alarm files as well as flash
updates). The LLM-1770 has all-digital architecture; therefore, no periodic calibration is
required.
The LLM-1770 seamlessly integrates into any broadcast, post-production, satellite or cable
facility, and is the ultimate choice for quality control, troubleshooting, or compliance
checking applications.
Product Features
The LLM-1770 includes the following standard and optional features.
Standard Features
Four dedicated AES inputs
One high density 15 pin sub-D connector for 1 LTC input, 1 GPO contact closure
output, and 4 GPI inputs
Ethernet port for reporting data or performing unit updates
PC control using a web browser
One universal 110/220 AC adapter that provides DC voltage power input
OLED 256×64 pixel monochrome display for unit monitoring and setup
Illuminated controls and indicators
