Safety Information

Before you use a Spectra Precision

®

 EPOCH

®

 50 GNSS system, make sure that you 

have read and understood this guide, as well as the safety requirements listed in this 
chapter. 

2.1

Warnings and Cautions

An absence of specific alerts does not mean that there are no safety risks involved.

Always follow the instructions that accompany a Warning or Caution. The information 
they provide is intended to minimize the risk of personal injury and/or damage to the 
equipment. In particular, observe safety instructions that are presented in the 
following formats:

C

WARNING – 

A Warning alerts you to a likely risk of serious injury to your person and/or 

damage to the equipment. A warning identifies the nature of the risk and the extent of 
possible injury and/or damage. It also describes how to protect yourself and/or the 
equipment from this risk. Warnings that appear in the text are repeated at the front of 
the manual.

C

CAUTION – 

A Caution alerts you to a possible risk of damage to the equipment and/or 

loss of data. A Caution describes how to protect the equipment and/or data from this risk.

2.2

Regulations and safety

The receivers contain an internal radio-modem and can send signals through 
Bluetooth

®

 wireless technology or through an external data communications radio. 

Regulations regarding the use of the Ultra High Frequency (UHF) radio-modems vary 
greatly from country to country. In some countries, the unit can be used without 
obtaining an end-user license. Other countries require end-user licensing. For licensing 
information, consult your local Spectra Precision dealer. Bluetooth operates in license-
free bands.

Before operating this receiver, determine if authorization or a license to operate the 
receiver is required in your country. It is the responsibility of the end user to obtain an 
operator’s permit or license for the receiver for the location or country of use. For FCC 
regulations, see 

Legal notices, page 2

.

2.3

Type approval

Type approval, or acceptance, covers technical parameters of the equipment related to 
emissions that can cause interference. Type approval is granted to the manufacturer of 
the transmission equipment, independent from the operation or licensing of the units. 
Some countries have unique technical requirements for operation in particular
