Not applicable
2.5 Trace antenna designs
Not applicable
2.6 RF exposure considerations
To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with minimum distance of 20cm from your body.
2.7 Antennas
This radio transmitter FCC ID: 2AKQD-M-302 has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.
| No. | Antenna Type | Antenna Gain | Impedance | Frequency Range |
| 1 | external antenna | 2.0dBi | 50Ω | 902-928MHz |
2.8 Label and compliance information
The final end product must be labeled in a visible area with the following” Contains
FCC ID: 2AKQD-M-302”
2.9 Information on test modes and additional testing requirements
Host manufacturer is strongly recommended to confirm compliance with FCC requirements for the transmitter when the module is installed in the host.
2.10 Additional testing, Part 15 Subpart B disclaimer
Host manufacturer is responsible for compliance of the host system with module installed with all other applicable requirements for the system such as Part 15 B
