3 Introduction
The LPT-24 is a frequency hopping spread spectrum (FHSS) transmitter module designed to be
compatible with FCC Part 15.247 (US) and RSS-210 (Canada) regulations for license free
operation in the 2.4000 to 2.4835 GHz frequency band.
This transmitter module is intended to be mounted on a carrier circuit board, which will be used
in a variety of housings. General applications will be for hand-held remote control of industrial
equipment.
This transmitter has an integrated on-board chip antenna, eliminating the need for an external
antenna.

6 User Information
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. Howeve r, 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 to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Caution - changes or modifications to this module not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
7 Labelling requirements
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.
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 label referring to the enclosed
FCC ID: “Contains FCC ID: IA9LPT24RC.”
