Product Usage Instructions

Hardware Design Recommendations

• All unused pins should be left floating; do not ground them.
• All GND pins must be well-grounded.
• Traces should not be routed underneath the module.

Power Supply

The transceiver module must be powered by a regulated voltage. It is recommended to keep the power supply line for VCC as short and low impedance as possible. Near the power pins, it is recommended to insert a ceramic decoupling capacitor (100nF).

Ground Plane

It is recommended to have a copper ground plane under the module. The ground plane should be unbroken.

Module Placement (PCB Antenna version)

• The antenna on the PCB has an omnidirectional radiation pattern.
• To maximize antenna efficiency, an adequate grounding plane must be provided under the module. Instead, the areas underneath and surrounding the antenna area must be free of copper.

FCC Statement

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,
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.
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 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 important announcement

Important Note:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada.
This device is intended only for OEM integrators under the following conditions:

1. The antenna must be installed such that 20 cm is maintained between the antenna and users,and
2. The transmitter module may not be co-located with any other transmitter or antenna,
3. For all products market in US, OEM has to limit the operation channels in CH00 to CH41 for 902-928MHz band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel 00-41).
