exhibiting observable damage or defect. Use of non-conforming parts, assemblies and accessories
may lead to injury or death.
!
WARNING
The remote control system you have purchased is designed to stop in a safe mode under a variety of
conditions. Some examples of these conditions are: excessive radio signal interference, loss of battery
or electrical power, failure of certain components and operation beyond signal range and others.
Although Laird and its subsidiaries does not specify the position of the operator when controlling the
equipment we are aware that some users are instructed and trained by their employer to ride the
equipment in a safe manner. It is imperative that you are prepared for an unplanned stop of the
equipment at any time and do not place yourself or others in a position where this situation may
cause you to fall from the equipment. Failure to use caution may lead to injury or death.

authority to operate the equipment
IC RSS-GEN, Sec 8.4 Warning Statement- (Required for license-exempt devices)
(ENGLISH) This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to
the following two conditions: (1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.
(FRENCH) Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas
produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi,
même si le brouillage est susceptible d'en compromettre le fonctionnement.

3SAFETY RULES
!
WARNING
Read all instructions. Failure to follow these rules can result in serious personal injury.
GROUND THE RECEIVER CASE. In order to ensure safety of the system, firmly connect the receiver
case to earth ground.
PROVIDE A SAFETY CUTOFF SWITCH. If maintenance is required, disconnect the radio from power to
prevent accidental activation.
USE PROPER WIRING. Loose or frayed wires can cause accidental machinery activation.
DO NOT INSTALL IN HOT AREAS. This apparatus can be damaged by heat in excess of 160° F.
DO NOT INSTALL IN HIGH VIBRATION AREAS. The life of this apparatus might be shortened through
long exposure to intense shaking or vibration.
3.1 Personal Safety
MAKE SURE MACHINERY IS CLEAR BEFORE OPERATING. Do not activate the remote system unless it is
safe to do so.
SWITCH OFF THE RECEIVER POWER BEFORE WORKING ON MACHINERY. Always disconnect the
remote system power before performing any maintenance to prevent accidental machine operation.
3.2 Care
KEEP DRY. If water or other liquids get inside the device, immediately dry the unit.
KEEP ANTENNAS CLEAN. Keep antenna connections clean and free of corrosion.
Note: Throughout this manual, other safety rules appear under the following heading:

4INTRODUCTION
4.1 Purpose
This manual provides information on the safe installation and operation of the Laird Command Pro® wireless
control systems. Information is also included on the maintenance and repair of the Command Pro systems.
4.2 Scope
Information is included on all types of Laird transmitters and receivers used in industrial applications. Refer to
the detailed information contained in each section for your particular equipment.
The transmitters covered in this manual contain enhanced features that expand the types of applications for
the systems.
Many new features have been added, but most changes are transparent to the user. If you are already
familiar with Laird transmitters, you are encouraged to read the section on operating the transmitters, where
there is information about the latest changes in operation.
To help you identify your system, Figure 1and Figure 2 provide a reference for the transmitters and receivers
covered in this manual. Review the Configuration Sheet that came with your equipment for details on the
types of switches and the labels used on your equipment.
4.3 Important Safety Rules
Using wireless control systems with heavy industrial equipment can improve the safety of the equipment.
It is important to adhere to the safety rules presented throughout this manual, especially during installation,
in order to achieve the safest operating system possible.
4.4 Carrying Strap for ‘Belly Box’ Controllers
A Shoulder Carrying Strap (Part #600057) is supplied with the 21T34A, T44A, T54A, and T74A ‘Belly Box’-style
controllers which greatly enhances operator comfort. Operators of these ‘Belly Box’-style controllers are
required to use this approved carrying strap with the controller attached at all times.

5OPERATIONS
Laird Command Pro Wireless Control Systems are designed to control industrial machinery. These rugged
controls are built to survive the wear and tear of life in factories, mills, and foundries.
These systems comply with operation requirements under Part 15 of the FCC Rules and Regulations. This
means that neither the operator nor the company need apply or register for a license to operate this
equipment.
The basic system consists of a transmitter and a receiver. The transmitter sends commands to the receiver
through radio waves in the 900 MHz band. Receivers operate at 120 VAC 50/60 Hz power. Operation from
other power sources is also available.
5.1 How the System Works
5.1.1 Frequency
Laird Command Pro equipment operates in the 902 to 928 Megahertz (MHz) frequency band. A wavelength
at our frequency is 12.9 inches.
Like light, 900 MHz radio signals pass through glass and plastics, and reflect off of walls, buildings, and metal
structures. Unlike light, 900 MHz radio signals penetrate all plastics including those opaque in color, as well
as thin-gauge steel, dry wood, dry concrete, plasterboard, fog, and rain. However, the signal will not readily
pass through trees, earth, water, people, aluminium, copper, and some window tints.
5.1.2 Range and Antenna Coverage
Antennas convert radio signals into radio waves, and convert radio waves back into radio signals. They can
send and receive in all directions or in a single direction, depending on their design.
An omnidirectional antenna is like a light bulb, and a directional antenna is like a flashlight. Metal objects
reflect radio waves, just as a mirror next to a light bulb will reflect light. Metal objects near an antenna alter
the intended pattern of an antenna by either shading or reflecting signals.
Our standard antennas are omnidirectional; they ‘see’ equally well in all directions. We have other antennas
that will ‘see’ further in one direction for special applications.
5.1.3 License-Free Channels
The 902 to 928 MHz spectrum accommodates many license-free users and is set aside by the FCC as an ISM
Band (Industrial, Scientific, and Medical). We have the ability to change frequencies in this band and have 81
different channels that we can assign to the transmitter and receiver. The actual frequency is coded into the
receiver and transmitter at the factory but may be changed to one of the other 80 channels in the field if
desired.
Other devices in this band include wireless phones, computer data links, and inventory equipment. As a
condition of using this band, products must accept and handle interference from other users.
The 900 MHz band works well for most users, and not being burdened with licensing regulations is desirable.
The FCC has allowed 50,000 microvolts per meter field strength on this band, which is 250 times higher than
other unlicensed frequencies below the band. This allows our systems to operate very reliably in the presence
of other signals.
