and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communication. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and the receiver.

- Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.
Changes and modifications not expressly approved by the
manufacturer or registrant of this equipment can void your authority to

operate this equipment under F ederal Communications Commission
rules.

Canada

This digital apparatus does not exceed the Class B limits for radio
noise emissions from digital apparatus as set out in the radio
interference regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de Classe B
prescrites dans le règlement sur le brouillage radioélectrique édicté par
le Ministère des Communications du Canada.

Safety Information

Most accidents that involve product operation, maintenance and repair are caused
by failure to observe basic safety rules or precautions. An accident can often be
avoided by recognizing potentially hazardous situations before an accident occurs.
A person must be alert to potential hazards. This person should also have the
necessary training, skills and tools to perform these functions properly.

Improper operation, lubrication, maintenance or repair of this product can be
dangerous and could result in injury or death.

Do not operate or perform any lubrication, maintenance or repair on this product,
until you have read and understood the operation, lubrication, maintenance and
repair information.

Safety precautions and warnings are provided in this manual and on the product. If
these hazard warnings are not heeded, bodily injury or death could occur to you or
to other persons.

The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal
Word” such as “DANGER”, “WARNING” or “CAUTION”. The Safety Alert
“WARNING” label is shown below.

WARNING — This alert warns of a potential hazard which, if not avoided, can cause severe

injury.

The meaning of this safety alert symbol is as follows:

Attention! Become Alert! Your Safety is Involved.

The message that appears under the warning explains the hazard and can be either
written or pictorially presented.

Operations that may cause product damage are identified by “NOTICE” labels on
the product and in this publication.

Trimble® cannot anticipate every possible circumstance that might involve a
potential hazard. The warnings in this publication and on the product are, therefore,
not all inclusive. If a tool, procedure, work method or operating technique that is
notspecifically recommended by Trimble is used, you must satisfy yourself that it is
safe for you and for others. You should also ensure that the product will not be
damaged or be made unsafe by the operation, lubrication, maintenance or repair
procedures that you choose.

The information, specifications, and illustrations in this publication are on the basis
of information that was available at the time that the publication was written. The
specifications, torques, pressures, measurements, adjustments, illustrations, and
other items can change at any time. These changes can affect the service that is

given to the product. Obtain the complete and most current information before you
start any job. SITECH dealers have the most current information available.

WARNING — When replacement parts are required for this product Trimble recommends

using Trimble replacement parts or parts with equivalent specifications including, but not
limited to, physical dimensions, type, strength and material. Failure to heed this warning can
lead to premature failures, product damage, personal injury or death.

CAUTION – Exposure to radio frequency (RF) energy is an important safety
consideration. The FCC has adopted a safety standard for human exposure to RF
electromagnetic energy emitted by FCC-regulated equipment as a result of its
actions in General Docket 79-144 on March 13, 1986. Proper use of this radio
results in exposure below government limits. Trimble recommends the following
precautions:

l Do not operate the transmitter when someone is within 20 cm (7.8 inches) of

the antenna.

l Do not operate the transmitter unless all RF connectors are secure and any

open connectors are properly terminated.

l Do not operate the transmitter near electrical blasting caps or in an explosive

atmosphere.

l Do not co-locate the antenna with any other transmitting device.
