1. Introduction
The eGPS 20TL GNSS Receiver Quick Start Guide describes
how to set up and use the eGPS 20TL GNSS receiver.
“The receiver” refers to the eGPS 20TL GNSS receiver
unless otherwise stated.
Even if you have used other Global Navigation Satellite
Systems (GNSS) products before, eGPS Solutions
recommends that you spend some time reading this manual
to learn about the special features of this product.
1.1. Safety Information
1.1.1. Warnings and Cautions
An absence of specific alerts does not mean that there are
no safety risks involved.
Warning or Caution information is intended to minimize the
risk of personal injury and/or damage to the equipment.
WARNING - A Warning alerts you to a potential
misuse or wrong setting of the equipment.
CAUTION - A Caution alerts you to a possible risk of
serious injury to your person and/or damage to the
equipment.
1.1.2. Regulations and Safety
The receivers contain a built-in wireless modem for signal
communication through Bluetooth®wireless technology or
through an external communication datalink. Regulations
regarding the use of the wireless modem vary greatly from
country to country. In some countries, the unit can be used
4

without obtaining an end-user license. However, in some
countries, administrative permissions are required. For
license information, consult your local dealer. Bluetooth®
operates in license-free bands.
Before operating an eGPS 20TL GNSS receiver,
determine if authorization or a license to operate the unit 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.
1.1.3. Use and Care
This receiver is ruggedized to withstand tough
environmental conditions that occur in the field. However,
the receiver is a high-precision electronic instrument and
should be treated with reasonable care.
CAUTION - Operating or storing the receiver
outside the specified temperature range will cause
irreversible damage.
1.2. Technical Support

2. Getting Started with the eGPS 20TL
2.1. About the Receiver
The eGPS 20TL GNSS receiver incorporates a GNSS engine,
GNSS antenna, internal radio, 4G cellular modem,
Bluetooth, WiFi and dual batteries in a ruggedized and min-
iature unit. Either unit may be a base, rover, or used without
other devices for static collection.
The LCD panel enables users to check satellite-tracking
status, internal battery status, WiFi status, working mode,
data logging status and basic receiver information.
The receiver can be used as part of a Network RTK GNSS
system with Carlson SurvCE, MicroSurvey Field Genius or
CHC LandStar7 Android software. Static positions can be
stored in Rinex 2.11 format for easy OPUS submittal using
only the receiver.
When using the eGPS 20TL without additional equipment,
configuration of the many features is accomplished through
a web browser. CHC LandStar7 may also be downloaded
from the Android app store. Static positions can be taken
by pressing the function button for 5 seconds.

2.3. Batteries and Power
2.3.1. Internal Batteries
The receiver comes with two rechargeable lithium-ion
batteries.
2.3.1.1. Charging the Batteries
The rechargeable lithium-ion batteries are supplied
partially charged. Charge the batteries completely before
using for the first time. To charge the batteries, place them
in the supplied charger and wait until the green light at
each battery stops flashing and remains solid green.
WARNING - Charge and use the rechargeable
lithium-ion batteries only in strict accordance with
the instructions. Charging or using the batteries in
unauthorized equipment can cause an explosion or
fire and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
• Do not charge or use the battery if it appears to be
damaged or leaking.
• Charge the lithium-ion battery only in an eGPS 20TL
charger that is specified to charge it. Be sure to
follow all instructions that are provided with the
battery charger.
• Discontinue charging a battery that gives off extreme
heat or a burning odor.
• Use the battery only in eGPS 20TL equipment.
• Use the battery only for its intended use and
according to the instructions in the product
documentation.

2.3.1.2. Battery Safety
WARNING - Do not damage the rechargeable
lithium-ion batteries. 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 leakage of
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.
WARNING - Avoid contact with the rechargeable
lithium-ion battery if it appears to be leaking.
Battery fluid is corrosive and contact with it can result
in personal injury and/or property damage.
To prevent injury or damage:
• If the battery leaks, avoid the battery fluid.
• If battery fluid gets into your eyes, immediately rinse
your eyes with clean water and seek medical
attention. Please do not rub your eyes!
• If battery fluid gets onto your skin or clothing,
immediately use clean water to wash off the battery
fluid.

2.3.2. External Power Supply
Two methods are available for providing external power to
the receiver. Use the included GPS to USB PC Data Cable
with Power Adapter and either the wall charging adapter or
the optional 12 volt battery cable.
In the office:
The Power Adapter is connected with AC power of
100 - 240 V and the output port of the Power Adapter
connects to the Power Port of the GPS to USB PC Data
Cable.
In the field:
The external power cable is connected with a vehicle
battery, and the output port of the external power cable
connects with the Power Port of the GPS to USB PC Data
Cable.
WARNING - Use caution when connecting external
power cable’s clip leads to a vehicle battery. Do not
allow any metal object to connect (short) the
battery’s positive(+) terminal to either the negative(-)
terminal or the metal part of the vehicle battery. This
could result in high current, arcing, and high
temperatures, exposing the user to possible injury.
