91-18296 Module Installation Federal Communication Commission Interference Statement 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 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. 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. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. Industry Canada Statement This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Avis de conformité pour l’Industrie Canada Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. 91-18296 Soldered onto MX1102 in location shown 91-18296 Installation Orientation UP © 2015 Onset Computer Corporation.

OEM Responsibilities to comply with FCC and Industry Canada Regulations The 91-18296 Module has been certified for integration into products only by Onset Computer Corporation under the following conditions: 1. The antenna(s) must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times. 2. The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter. As long as the two conditions above are met, further transmitter testing will not be required. However, Onset Computer Corporation 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.). IMPORTANT NOTE: In the event that these conditions can not be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and IC Certification Number can not be used on the final product. In these circumstances, Onset Computer Corporation will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and Industry Canada authorization. End Product Labeling The 91-18296 Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC Certification Number are 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 module. In that case, the final end product must be labeled in a visible area with the following: "Contains Transmitter Module FCC ID: WXF-ONST1" "Contains Transmitter Module IC: 7936A-ONST1" or "Contains FCC ID: WXF-ONST1" "Contains IC: 7936A-ONST1" Onset Computer Corporation must only use the approved antenna(s) listed above, which have been certified with this module. Onset Computer Corporation has to be aware not to provide information to the end user regarding how to install or remove this RF module or change RF related parameters in the user manual of the end product. © 2015 Onset Computer Corporation.

Testing was performed with the module located inside of the intended host device. (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. 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 module. A sample of the host label is provided as an exhibit, showing the FCC identifier of the module. (vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. The module complies fully with all of the relevant FCC requirements and the adequate instructions to keep the compliance have been provided in the Module Manual. (viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. The module will be installed in a host product where the transmitting antenna can provide 20 cm separation distance to the body of user. Installation of this module is intended for professional installation only.

Radiated Emissions were maximized by rotating the device around its axes as well as varying the test antenna’s height and polarity. The antenna was maximized separately. Conducted emissions at the antenna port were performed, as required by rule section. The EUT operating voltage is 6Vdc (4xAA battery). No AC Line conducted testing required. Low operating channel frequency = 2402MHz Mid operating channel frequency = 2440MHz High operating channel frequency = 2480MHz The following bandwidths were used during radiated spurious and line conducted emissions.
