The CSxxxTRT-1-1 RF part is a transceiver with multiple functions:
1. Transmitting or Receiving (simplex or halfduplex)
2. “Feedback Master” or “-Slave” for 3 LED-Feedback (halfduplex).
The functions are selectable by SIP-Switch for frequency allocations and solder jumper to select
Transmitter/Receiver, FB-Master or FB-Slave.
The TRT (CSxxxTRT-1-1) has four holes to be mounted on screw bosses or it is mounted in
module slots in transmitter housings.
The counterpart of the TRT is the TRR (CSxxxTRR) module which is formed to be used in
receivers.
The TRT has an ISP port (In System Programming) which makes it possible to download new
firmware.
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. Changes or
modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
(2) NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:
‐Reorient or relocate the receiving antenna.
‐Increase the separation between the equipment and the receiver.
‐Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
‐RF Radiation Hazard Warning (products with activated transmit option only): To ensure
compliance with FCC RF exposure requirements, this product should be positioned no less than 20
cm from your body or nearby persons during continuous use.

The CSxxxTRT can work with the following baud rates (depending on frequency band):
Notice:
It is recommended to use 3.4-5VDC power supply to reduce heat dissipation if available.
If module is used in automatic mode the decrement channel switch should be interlocked
with the STOP switch so that it is not possible to change channel during normal operation.
This way the channel change can only be done when the system is in STOP condition and
an accidental channel change in normal conditions is prevented.

05 Integration instructions for host produc t manufacturers
according to KDB 996369 D03 OEM Manual v01
2.2 List of applicable FCC rules
Part 90
2.3 Specific operational use conditions
This module is approved for use in portable and mobile applications. Integrators must supply
operating instructions for end users and installers to satisfy RF exposure compliance requirements
are met. Integrators and installers must also make sure that compliance with Part 15B are ensured.
2.4 Limited module procedures
N/A, this module is not compliant with Chapter (b) from §15.212.
2.5 Trace antenna designs
N/A, the module does not use a trace antenna, it uses an external dipole antenna.
2.6 RF exposure considerations
WARNING: The 456TR1 device radiates radio frequency energy at a level below the United
States FCC radio frequency exposure limits. Nevertheless, this device should be used in such a
manner that the potential for human contact during normal operation is minimized. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC
peripheral requirements, etc.).
2.7 Antennas
Antenna is named with IANT419458. It´s a168mm long wire antenna with a MMCX-Connector
and connected to the RF-part CS456 TRT-1

2.8 Label and compliance information
The 456TR1 module is labelled with its own FCC ID. If the FCC ID is not visible when the
module is installed inside another device, then the outside of the device into which the module is
installed must also display a physical label or eLabel referring to the enclosed module. In that case
the end product must be labelled in a visible area with the following: Contains
FCC ID: 2AC8P-456TR1.
