Rechargeable Lithium-ion Batteries
This receiver uses one rechargeable Lithium-ion
battery.
WARNING - Do not damage the rechargeable Lithi-
um-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 dam-
age:
• Do not use or charge the batteries if they ap-
pear to be damaged. Signs of damage include,
but are not limited to, discoloration, warping,
and leaking battery fluid.
• Do not expose the batteries to fire, high tem-
perature, or direct sunlight.
• Do not immerse the batteries in water.
• Do not use or store the batteries inside a vehi-
cle during hot weather.
• Do not drop or puncture the batteries.
• Do not open the batteries or short-circuit their
contacts.
WARNING - Avoid contact with a rechargeable Lith-
ium-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 a battery leaks, avoid contact with the bat-
tery fluid.
• If battery fluid gets into your eyes, immediate-
ly rinse your eyes with clean water and seek
medical attention. Do not rub your eyes!
• If battery fluid gets onto your skin or clothing,
immediately use clean water to wash off the
battery fluid.
WARNING - Charge and use the rechargeable Lith-
ium-ion batteries only in strict accordance with the
instructions. Charging or using the batteries in un-
authorized equipment can cause an explosion or
fire, and can result in personal injury or/and equip-
ment damage. To prevent injury or damage:
• Do not charge a battery if it appears to be dam-
aged or leaking.
• USE EXCLUSIVELY the dual-battery charger
(P/N 53018010-SPN) or the AC/DC power
supply (P/N 107000) to charge the SP90m
Lithium-ion battery. See instructions in this
guide. These two devices are part of the
SP90m standard accessories list.
CHARGE THE BATTERIES ONLY IN THE
TEMPERATURE RANGE 0° to +40°C (32° to
104°F), at a maximum altitude of 2,000 me-
ters (6,562 feet).
• Discontinue charging a battery that gives off
extreme heat or a burning odor.
• Use the batteries only in Spectra Precision
equipment that is specified to use them.
• Use the batteries only for their intended use
and according to the instructions in the prod-
uct documentation.
Disposing of the Rechargeable Lithium-ion Battery
Discharge the Lithium-ion battery before disposing
of it. When disposing of the battery, be sure to do
so in an environmentally sensitive manner. Adhere
to any local and national regulations concerning
battery disposal or recycling.
CAUTION - RISK OF EXPLOSION IF BATTERY IS
REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO
THE INSTRUCTIONS”
ATTENTION - RISQUE D'EXPLOSION SI LA BAT-
TERIE EST REMPLACÉE PAR UNE BATTERIE DE
TYPE INCORRECT.
METTRE AU REBUT LES BATTERIES USAGÉES
CONFORMÉMENT AUX INSTRUCTIONS.
Receiver Use and Care
The receiver can withstand the rough treatment
that typically occurs in the field. However, the re-
ceiver is a high-precision electronic instrument and
should be treated with reasonable care.
CAUTION - Operating or storing the receiver out-
side the specified temperature range can damage
it. For more information, see Physical Specifica-
tions in this guide.
High-power signals from a nearby radio or radar
transmitter can overwhelm the receiver circuits.
This does not harm the instrument, but it can pre-
vent 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 inter-
fere with receiver operations.

For more information, contact your Spectra Precision
distributor.
Bluetooth & Wifi Radios
The radiated output power of the wireless radios is far
below the FCC radio-frequency exposure limits. Nev-
ertheless, the wireless radios shall be used in such a
manner that the Spectra Precision receiver is 30 cm
(11.8”) or further from the human body.
The internal wireless radios operate within guidelines
found in radio-frequency safety standards and rec-
ommendations, which reflect the consensus of the
scientific community. Spectra precision therefore be-
lieves the internal wireless radios are safe for use by
consumers.
The level of energy emitted is far less than the elec-
tromagnetic energy emitted by wireless devices such
as mobile phones. However, the use of wireless radi-
os may be restricted in some situations or environ-
ments, such as on aircraft. If you are unsure of
restrictions, you are encouraged to ask for authoriza-
tion before turning on the wireless radios.
COCOM Limits
The US Department of Commerce requires that all
exportable GNSS products contain performance lim-
itations 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 re-
ceiver: 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 17,000 me-
ters (59,055 feet). The receiver continuously resets
until the COCOM situation is cleared.
Technical Assistance
If you have a problem and cannot find the informa-
tion you need in the product documentation, contact
your local distributor. Alternatively, request technical
support using the Spectra Precision website at

UHF Radios
Regulations and Safety. The receiver may be fitted
with an internal radio as an option. It can also be
connected to an external UHF radio.
Regulations regarding the use of Ultra High Frequen-
cy (UHF) radio-modems vary greatly from country to
country. In some countries, the UHF kit may be used
without obtaining an end-user license. Other coun-
tries require end-user licensing. For licensing infor-
mation, consult your local Spectra Precision dealer.
Before operating the receiver with the UHF kit, deter-
mine if authorization or a license to operate the UHF
kit is required in your country. It is the end-user’s re-
sponsibility to obtain an operator’s permit or license
for the location or country of use.
Exposure to RF energy is an important safety consid-
eration. 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 within 30 cm (11.8 inches) of the antenna.
• DO NOT collocate (place within 30 cm) the ra-
dio 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 electric
blasting caps or in an explosive atmosphere.
• All equipment must be properly grounded ac-
cording to Spectra Precision installation in-
structions for safe operation.
• All equipment should be serviced only by a qual-
ified technician.

Introduction to SP90m
The Spectra Precision SP90m is a powerful, highly versatile,
ultra-rugged, and reliable GNSS positioning solution for a
wide variety of real-time and post-processing applications. It
also comes with a variety of integrated communications
options, such as Bluetooth, WiFi, UHF radio, cellular modem,
and two MSS L-band channels to receive Trimble RTX
correction services.
The modular design of the SP90m allows for maximum
flexibility on how the receiver can be used, such as base
station, continuously operating reference station (CORS),
RTK/RTX rover, for on-board machine integration, vessels,
etc. The ultra-rugged design of the aluminum receiver
housing protects the investment, especially in tough field
environments.
The state-of-the-art and patented Z-Blade GNSS-centric
technology uses all available GNSS signals to deliver fast and
reliable real-time positions. Besides supporting all currently
available and future planned GNSS satellite signals, the
SP90m GNSS receiver allows the connection of two GNSS
antennas for precise heading determination without the need
for a secondary GNSS receiver.

2
First Steps
Unpacking In its basic version, the SP90m is delivered with a transport
bag, a Li-Ion battery, a dual-battery charger with battery
inserts, an AC/DC power supply, a Bluetooth/WiFi antenna
and accessories (see details in System Components Overview
on page 4).
Additionally, a choice of GNSS antenna and coaxial cable
should have been made, as well as that of a country-specific
power cord.
When the chosen model of SP90m includes an internal radio,
the power cable is different and a UHF antenna is added to
the supply (see details on page 4).
Basic Setup You may have the Li-Ion battery charged separately on the
dual-battery charger (see page 24) or it can be placed in the
receiver (see page 13) to be charged by the external DC
source (AC/DC power supply) when connected as indicated
below.
Default
Configuration
The SP90m is shipped from the factory in the following
configuration:
• Antenna configuration: Single antenna (GNSS input #1)
• Selected GNSS constellations and signals: All
• Elevation mask (for position and raw data): 5 degrees
• Anti-theft and startup protection: Both OFF
• Base Mode: OFF (the receiver will operate as a rover)
• Receiver with internal radio: Radio is ON
• GSM, WiFi: Both devices OFF

steps needed before operating the receiver in the
requested mode may be taken directly from within Survey
Pro. Typically in this case, a Bluetooth connection will be
used between the data controller running Survey Pro and
the SP90m.
