Safety
Caution
Grounding the Terminal
In urban areas, ground the terminal with a grounding conductor in
accordance to national and local electrical codes.
Danger
FCC Radio Frequency Exposure Information for Mobile Transmitting
Devices
When the power is on, maintain an off-axis safety distance of 0.7 meters
(2.3 feet), where “off axis” means 0.9 meters (3 feet) from the center of the
beam, and maintain an on-axis safety distance of 7 meters (23 feet).
Danger
Electrical Hazards in Wet and Windy Conditions
While the terminal is designed for outdoor use (e.g. optional waterproof
power supply), observe the following safety precautions during windy and
wet weather conditions. Some steps may not apply depending on the BUC
configuration.
Check cable connectors and power cords for damage or tears. Replace
cables and cords as needed.
Disconnect the terminal from its power source before you move it.
Disconnect the terminal from its power source if you suspect a power
malfunction
Warning
Hot Surfaces
When transmitting, do not touch the BUC as it may result in burns or injury.
Danger
Hazards of Microwave Radiation in Electromagnetic Fields
When the power is on, the area directly in front of the antenna is an Area of
Restricted Occupancy. Observe the following safety precautions:
1. Limit human exposure time to the area directly in front of the main antenna
assembly.
2. Never place any part of your body between the antenna and the Feed Horn
assembly.
3. Never place any part of your body in line with the direction of the antenna
transmission path.
4. Locate the terminal as far as possible from ungrounded metal.

Dielectric Heating
Dielectric heating is the heating of an insulating material caused by placing it
in a high frequency electric field. When a human enters a Radio Frequency
(RF) field, the body acts as dielectric. If the power in the RF field exceeds 10
milliwatts per centimeter, the individual will have a noticeable rise in body
temperature.
The severity of burns may vary from minor to major. Burns or other damage
may result in long term injury or even death.
The vital organs of the body are highly susceptible to dielectric heating.
The eyes are also highly susceptible to dielectric heating. Do not look directly
into devices radiating RF energy.
You must not stand directly in the path of RF radiating devices
Warning
Unintentional Radio Interference
This equipment generates, uses, and radiates radio frequency energy. If you
install and use the device according to the instruction manual, the device
will not cause harmful interference to radio communications.
If you operate the device in a residential area, it is likely to cause harmful
interference to radio communications; you will correct the interference at
your own expense.
Warning
Changes or Modifications to Equipment
Changes or modifications to this equipment, not expressly approved by the
manufacturer
could void the user’s authority to operate the equipment.
Accessories and Devices
Use of non-approved accessories or devices may lead to a degradation in
performance, damage to equipment, or potential hazards
Servicing the Equipment
Do not service the equipment alone unless another person is present to
administer first-aid

Preface
Purpose and Scope of the User Guide
The user guide explains the system specifics of the Norsat GLOBETrekker™ satellite terminal.
This user guide is specifically written for the 1.0m GLOBETrekker™
Audience
The guide will be of interest to the following personnel:
•Field users
•Systems administrators (or IT; Lifecycle/Sustainment Managers)
READ THE MANUAL BEFORE YOU INSTALL OR OPERATE THE
GLOBETREKKER™

1. Positioning the System
1.1 Site Selection
1. Find a clear level area. The GLOBETrekker™ can handle 10 degrees of angle on the system, but
time to acquisition may suffer.
2. Ensure that there is a clear view of the sky towards the equator and target satellite
a. You can use a product like Norsat’s Satellite Finder to assist in checking for view angles.
3. Ensure that you have access to sufficient power
4. Ensure that you can provide a safe clearance area or prevent people from walking in the way of
transmission.
1.2 Clearance Distance

1.3 High Wind Set-up
If the system is to be used in a high wind situation ensure that you have sufficient ballast or tie downs to
secure the legs of the GLOBETrekker™

* Note: the specified ballasts are assumed to be applied directly on top of the footpad. If the ballast is
applied further up the leg then the mass must be increased. Contact Norsat for details.
2. Assembling the System
This chapter details the steps necessary to assemble a GLOBETrekker ™
Disassembly is done by reversing the following instructions
2.1 Preparing the cases
1. Ensure that all the transit cases are at hand.
2. Unlatch the cases
2.2 Deploying the Legs for the Base band unit
1. Remove the BBU from the BBU case. The BBU provides the mounting points for the four (4) legs.

2. Place the system so that the leg mount brackets are visible.
Figure 2: Backside of the Baseband Unit
3. Hook the legs into the slots of the brackets. Ensure the locating pins on the brackets are aligned with
the slots in the legs. Assemble so that the legs are flat on the bracket. Secure the legs using
thumbscrews.

Figure 3: Supporting Legs and the Bracket
4. Place the system on its legs in the general direction of the satellite.
Figure 4: Place the System to Face the Right Position
Example: If your position is north of the equator, place the unit with the front facing the South.
5. Level the BBU using the threaded feet on the quad pod legs. The spirit level in the top of the unit will
assist in the leveling process.
