1 Introduction
The Flex radio remote control systems are designed for control of industrial equipment and machinery
such as overhead traveling cranes, jib cranes, gantry cranes, tower cranes, electric hoists, winches,
monorails, conveyor belts, mining equipment and other material handling equipment where wireless
control is preferred.
Each Flex HazLoc system consists of a Flex HazLoc transmitter handset and Flex receiver unit. Other
standard-equipped accessories include transmitter waist belt, spare transmitter power key, clear vinyl
pouch, “AA” alkaline batteries, compass direction decal sheet and user’s manual.
List of notable features includes:
•62 user-programmable channels – Advanced synthesized RF controls with 62 built-in channels;
there are no more fixed channels and fragile quartz crystals to break.
•Automatic channel scanning receiver – No more hassle of climbing up the crane to change
receiver channels.
•Over 1 million unique ID codes (20-bit) – Every Flex system has its own unique ID codes and
serial number; no repeats.
•Advanced controls – The Flex system utilizes advanced microprocessor controls with 32-bit
CRC and Hamming Code, which provide ultra-fast, safe, precise, and error-free encoding and
decoding.
•Unique I-CHIP design – The I-CHIP functions in a way that is very similar to SIM cards used on
mobile phones, with the ability to transfer system information and settings from one transmitter to
another without the hassle of resetting the spares.
•Reliable pushbuttons – The in-house-designed pushbuttons with gold-plated contacts are rated
for more than 1 million press cycles.
•Low power consumption – Requires only two “AA” alkaline batteries for more than 100 hours of
operating time between replacements.
•Ultra-durable nylon and fiberglass composite enclosures – Highly resistant to breakage and
deformation, even in the most abusive environments.
•Full compliance – All systems fully comply with the FCC Part-15 Rules, European Directives
(Safety, EMC, RED, and Machinery), and Industry Canada Specifications (IC).

2 Critical Installation Considerations
2.1 General
Radio-controlled equipment operates in several directions. The equipment is often operated in areas
where people are working in close proximity to the equipment. The operator must exercise extreme
caution at all times. Workers must constantly be alert to avoid accidents. The following recommendations
have been included to indicate how careful and thoughtful actions may prevent injuries, prevent damage to
equipment, or even save a life.
2.2 Persons Authorized to Operate Radio-Controlled
Cranes
Only properly trained persons designated by management should be permitted to operate radio-controlled
equipment.
Radio-controlled equipment should not be operated by any person who cannot read or understand signs,
notices and operating instructions that pertain to the equipment.
Radio-controlled equipment should not be operated by any person with insufficient eyesight or hearing or
by any person who may be suffering from a disorder or illness that may cause them to lose control of the
equipment, is taking any medication that may cause loss of equipment control, or is under the influence of
alcohol or drugs.
WARNING
Prior to installation and operation of this equipment, read and develop an understanding of the contents
of this manual and the operation manual of the equipment or device to which this equipment will be
interfaced. Failure to follow this warning could result in serious injury or death and damage to
equipment.
Follow your local lockout/tagout procedure before maintaining any remote-controlled equipment.
Always remove all electrical power from the equipment before attempting any installation procedures.
De-energize and tagout all sources of electrical power before touch-testing any equipment. Failure to
follow this warning could result in serious injury or death and damage to equipment.
After installation, be sure to verify that the transmitter is not interfering with other equipment in the area.

2.4 Transmitter Unit
Transmitter switches should never be mechanically blocked on or off. When not in use, the operator should
turn the transmitter off. A secure storage space should be provided for the transmitter unit, and the
transmitter unit should always be placed there when not in use. This precaution will help prevent
unauthorized people from operating the material handling equipment.
Spare transmitters should be stored in a secure storage space and only removed from the storage space
after the current transmitter in use has been turned off, taken out of the service area and secured.
2.5 Pre-Operation Test
At the start of each work shift, or when a new operator takes control of the equipment, operators
should do, as a minimum, the following steps before making lifts with any equipment:
Test all warning devices.
Test all functions.
Test the transmitter machine stop.
WARNING
The operator should not attempt to repair any radio controller. If any product performance or safety
concerns are observed, the equipment should immediately be taken out of service and be reported to
the supervisor. Damaged and inoperable radio controller equipment should be returned to Magnetek
for evaluation and repair. Failure to follow this warning could result in serious injury or death and
damage to equipment.
