SATEL-TR489 radio transceiver module has been designed to operate on 403-473 MHz, 856-876
MHz and 902-928 MHz, the exact use of which differs from one region and/or country to another.
The user of a radio transceiver module must take care that the said device is not operated
without the permission of the local authorities on frequencies other than those specifically
reserved and intended for use without a specific permit.
SATEL-TR489 is allowed to be used in the following countries. More detailed information is
available at the local frequency management authority.
Countries: AT, AU, BE, BG, CA, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HU, HR, IE, IS, IT, LT, LU,

RESTRICTIONS ON USE –SATEL-TR489
WARNING –RF Exposure! To comply with RF exposure compliance requirements in
Europe maximum antenna gain is 14dBi and a separation distance of at least 1 meter
must be maintained between the antenna of this device and all persons.
WARNING! Users of SATEL-TR489 radio transceiver module in North America should
be aware, that due to the allocation of the frequency band 406.0 –406.1 MHz for
government use only, the use of radio transceiver module on this frequency band
without a proper permit is strictly forbidden.
WARNING - RF Exposure
To comply with FCC and IC RF exposure compliance requirements, maximum antenna
gain is 14 dBi and separation distance of at least 1 meter must be maintained
between the antenna of this device and all persons. This device must not be co-
located or operating in conjunction with any other antenna or transmitter.

Under the sole responsibility of manufacturer SATEL Oy declares that SATEL-TR489 radio
transceiver module is in compliance with the essential requirements (radio performance,
electromagnetic compatibility and electrical safety) and other relevant provisions of Directives
2014/53/EU and 2011/65/EU and Council recommendation 1999/519/EC. Therefore, the
equipment is labeled with the following CE-marking. The operating frequency range of the device
is not harmonized throughout the market area, and the local spectrum authority should be
contacted before the usage of the radio module.

Read these safety instructions carefully before using the product:
-Warranty will be void, if the product is used in any way that is in contradiction with the
instructions given in this manual
-The radio transceiver module is only to be operated at frequencies allocated by local
authorities, and without exceeding the given maximum allowed output power ratings. SATEL
and its distributors are not responsible, if any products manufactured by it areused in unlawful
ways.
-The devices mentioned in this manual are to be used only according to the instructions
described in this manual. Faultless and safe operation of the devices can be guaranteed only if

To ensure compliance with all non-transmitter functions the host manufacturer is responsible
for ensuring compliance with the module(s) installed and fully operational. For example, if a
host was previously authorized as an unintentional radiator under the Declaration of
Conformity procedure without a transmitter certified module and a module is added, the host
manufacturer is responsible for ensuring that after the module is installed and operational the
host continues to be compliant with the Part 15B unintentional radiator requirements. This
module is certified for Fixed and Mobile Applications only, for portable applications you will
require a new certification.
This device has been modularly approved. Model name, FCC and Industry Canada identifiers of
this product must appear on the outside label of the end-user equipment.
Host labelling example:
HOST INTEGRATION
Model Name: SATEL-TR489
Contains FCC ID: Coming soon
IC: Coming soon
This device complies with part 15 of the FCC
rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any
interference received, including interference that
may cause undesired operation.

1.2 Description of the product
The SATEL-TR489 is UHF radio transceiver module, which transmits and receives data from the
UHF frequency band. The module is designed to be as compact and power efficient as possible.
Theyhavebeendeveloped tobeespeciallysuitable forintegrationintobattery poweredand
space constrained host applications benefiting from UHF communications.
The module transmits and receives data via the Air interface, modulates and demodulates,
encodes and decodes the data and sends the received data payload to the DTE port. The DTE
interface is used to provide power and communicate with the module.

4 Measured under normal ambient conditions, TA = 25 °C. When the device is used in different
environment, the results may change significantly. It is recommended to use external ESD
protection in demanding conditions.
