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. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Product Labeling This radio module is labeled with an FCC ID number and a Canadian Certification Number. If this label is not visible when installed in an end-device, the outside of the device MUST also display a label referring to the enclosed OS2401. Use wording on the label similar to the following: "Transmitter Module FCC ID: OQ7OS2401, Canada 3656AOS2401". OR "This device contains Transmitter Module FCC ID: OQ7OS2401, Canada 3656AOS2401" CAUTION: Changes or modifications to this radio module not expressly approved by its manufacturer, Locus, Inc., may void the user’s authority to operate the equipment. NOTES: • Only approved antennas and power amplifier listed in this manual may be used with the OS2401. • The OS2400 Radio Module does not need to be re-authorized for compliance with Part 15,C intentional radiation (15.247 spread spectrum rules) or Part 15, B unintentional radiation. However, if the device into which the module is inserted contains any frequency sources (oscillator, clocks, etc.) it will have to be verified according to Part 15, B unintentional radiation to make sure that it does not unintentionally radiate. Page 3 of 11 6/17/2003 Antenna spacing requirements for user safety It is important to keep the radio’s antenna a safe distance from the user. To meet the requirements of FCC part 2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20 cm between the antenna and users. Greater distances are required for high-gain antennas; for more details, see the Choosing the Antennas section. The FCC requires a minimum distance of 1 mW *cm 2 power density from the user (or 20 cm, whichever is greater). The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF fields in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.

RF Exposure Calculations From FCC 1.1310 table 1A, the maximum permissible RF exposure for an uncontrolled environment is 1mW/(cm 2 ). The electric field required to generate power density exposure (S) of 1mW/(cm 2 ) is calculated as follows: S E 2 Z := where S is Power Density (W/m 2 ), E is electric field (V/m) and Z is the impedance of free space (377Ω). Thus the Electric Field allowable (E a ) to limit Power Density to 1mW/(cm 2 ), given that 1mW/(cm 2 ) is equivalent to 10W/m 2 , is given by: E a SZ ⋅ := E a 10 W m 2       ⋅ 377 ⋅Ω⋅:= E a 61.4 V m = Maximum conducted peak output power (P out ) from the OQ7OS2401 radio module without the amplifier is 16.1dBm. Given an antenna gain (G ant ) of 24dB, the maximum effective isotropic radiated power (EIRP) is 10.2W as shown below. P rad 10 P out G ant + 10       mW ⋅:= P rad 10.2W = Since power density S (W/m 2 ) is related to effective radiated power P (watts) by the following equation, S P 4 π⋅ D 2 ⋅ := and using the relationship between S and E above, the following equation can be derived for the minimum safe separation distance to ensure exposure limits below 1mW/cm 2 . D min P rad 377 Ω⋅ 4 π⋅       ⋅ E a := D min 28.5cm = Repeating the calculations with the amplifier, the maximum output power of 19.5dBm and maximum antenna gain of 13dB result in a minimum safe separation distance of 11.9cm.
