MRF24J40MA 1.0 DEVICE OVERVIEW The MRF24J40MA is a 2.4 GHz IEEE Std. 802.15.4™ compliant, surface mount module with integrated crystal, internal voltage regulator, matching circuitry and PCB antenna. The MRF24J40MA module operates in the non-licensed 2.4 GHz frequency band and is FCC, IC, and ETSI compliant. The integrated module design frees the end user from extensive RF, antenna design, and regulatory compliance testing and allows quicker time to market.

MRF24J40MA 4.0 REGULATORY APPROVAL The MRF24J40MA module has received regulatory approvals for modular devices in the United States, Canada and European countries. Modular approval allows the end user to place the MRF24J40MA module inside a finished product and not require testing for an intentional radiator (RF transmitter) provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user's authority to operate the equipment.

MRF24J40MA The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of FCC RF Exposure compliance: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended.
