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
C
2.2 Regulations and safety
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.
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.
The receivers contain an internal radio-modem and can send signals through
®
Bluetooth
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 licensefree 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 Notices, page -2.
wireless technology or through an external data communications radio.
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
EPOCH 35 GNSS System User Guide 3
Safety Information
radio-modem frequency bands. To comply with those requirements, Spectra Precision
may have modified your equipment to be granted Type approval. Unauthorized
modification of the units voids the Type approval, the warranty, and the operational
license of the equipment.
2.4 Exposure to radio frequency radiation
24.1 For UHF radio
For example, a 450 MHz radio.
Safety. Exposure to RF energy is an important safety consideration. The FCC has
adopted a safety standard for human exposure to radio frequency electromagnetic
energy.
Proper use of this radio modem results in exposure below government limits. The
following precautions are recommended:
• DO NOT operate the transmitter when someone is 20 cm (7.8 inches) of the
antenna.
• DO NOT collocate (place within 20 cm) the radio antenna with any other
transmitting device.
• DO NOT operate the transmitter unless all RF connectors are secure and any
open connectors are properly terminated.
• DO NOT operate the equipment near electrical blasting caps or in an explosive
atmosphere.
• All equipment must be properly grounded according to Spectra Precision
installation instructions for safe operation.
• All equipment should be serviced only by a qualified technician.
24.2 For Bluetooth radio
The radiated output power of the internal Bluetooth wireless radio is far below the
FCC radio frequency exposure limits. Nevertheless, the wireless radio shall be used in
such a manner that the Spectra Precision receiver is 20 cm or further from the human
body. The internal wireless radio operates within guidelines found in radio frequency
safety standards and recommendations, which reflect the consensus of the scientific
community. Spectra Precision therefore believes the internal wireless radio is safe for
use by consumers. The level of energy emitted is far less than the electromagnetic
energy emitted by wireless devices such as mobile phones. However, the use of wireless
radios may be restricted in some situations or environments, such as on aircraft. If you
are unsure of restrictions, you are encouraged to ask for authorization before turning
on the wireless radio.

2.5 Installing antennas
Safety Information
C
CAUTION – For your own safety, and in terms of the RF Exposure requirements of the FCC,
always observe these precautions:
– Always maintain a minimum separation distance of 20 cm (7.8 inches) between yourself
and the radiating antenna.
– Do not collocate (place within 20cm) the radio antenna with any other transmitting
device.
This device has been designed to operate with the antennas listed below.
UHF Antennas not included in this list, or having a gain greater than 5 dBi, are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
The antennas that can be used (country dependent) with the UHF radio are 0 dBi and
5 dBi whip antennas.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that permitted for successful communication.
2.6 Rechargeable Lithium-ion batteries
These receivers use a rechargeable Lithium-ion battery.
C
WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.

1 Introduction
1.1 About the EPOCH 35 L1/L2 GNSS system
The EPOCH 35 GNSS receiver uses an internal GNSS antenna and is designed for
GNSS surveying applications.
The base consists of a receiver, designed to operate with an external PacificCrest PDL
radio (“PacCrest”), and an external battery. For information on the PacCrest radio and
the external battery please refer to the documentation included with the radio kit.
The rover consists of a receiver, internal radio with receive option, and a removable
battery in a rugged lightweight unit.
1.2 Features
An LED screen on the receiver allow you to monitor the satellite tracking, radio
reception, file status, and power. Bluetooth
®
technology inside the receiver provides
cable-free communications between receiver and controller.
The receiver provides 54 channels (14 L1,14 L2 GPS, 12 L1, 12 L2 GLONASS, 2 SBAS)
full-cycle carrier satellite tracking and supports logging of raw GNSS observables to the
SD memory card.
The receiver provides the following features:
• Centimeter-accuracy, real-time positioning with RTK
• 54 channels L1 C/A code, L1/L2 full-cycle carrier
• WAAS/EGNOS capability (Wide Area Augmentation System/European
Geo-Stationary Navigation System)

1.3 Use and care
The receiver can withstand the rough treatment that typically occurs in the field.
However, the receiver is a high-precision electronic instrument and should be treated
with reasonable care.
Introduction 1
C
CAUTION – Operating or storing the receiver outside the specified temperature range can
damage it. For more information, see Chapter 4, Specifications.
High-power signals from a nearby radio or radar transmitter can overwhelm the
receiver circuits. This does not harm the instrument, but it can prevent the receiver
from functioning correctly. Do not use the receiver within 400 meters (1312 feet) of
powerful radar, television, or other transmitters. Low-power transmitters such as those
used in cell phones and two-way radios do not normally interfere with receiver
operations.
For more information, contact your Spectra Precision distributor.
1.4 COCOM limits
The U.S. Department of Commerce requires that all exportable GNSS products contain
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States.
The following limitation is implemented on the receiver: Immediate access to satellite
measurements and navigation results is disabled when the receiver’s velocity is
computed to be greater than 1000 knots, or its altitude is computed to be above
18,000 meters (59,055 feet). The receiver continuously resets until the COCOM
situation is cleared.

31.1 Rover receiver
WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
The rover receiver can be powered by its internal, removable battery or by an external
power source connected to Port 1 or Port 2. Typically, one internal 2.4 Ah battery
provides approximately 5.5 hours of operation during an RTK survey when the internal
radio is used in Rover mode. The basic kit contains two batteries for up to 11 hours of
total operation. The base receiver can also run on an internal 2.4 Ah battery as a
network RTK rover.
If an external power source is connected to Port 1 or Port 2, it is used in preference to
the internal battery. When there is no external power source connected, or if the
external power supply fails, the internal battery is used.
31.2 Base receiver
The base receiver is powered by an external 12 V battery, which lasts 12 hours in
continuous use.
22 EPOCH 35 GNSS System User Guide
31.3 Charging and storing batteries
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long
periods of time, make sure it is fully charged before storing and re-charged at least once
every three months.
