| This device has integrated DSS, DTS, DSC and DXX transmitters certified under the same FCC ID. SAR compliance for body-carry configurations is limited to provision at least 0 cm separation between the device and the user's body. The highest reported SAR values for body-worn accessory and simultaneous transmission use conditions are <0.10 W/kg and 0.67 W/kg at 1g tissues, respectively. Class II Permissive Change for: 1. Some optocoupler devices are reduced. And added 0 ohm resistance. Their modifications are only related to OBD-related functionality, it has nothing to do with wireless functions. 2. Modified the logic device U704 is added in the 125 kHz acquisition and receiving part, and some logic devices are not welded, and the corresponding principle is modified. 3. Update the software version to: V1.5.1, 4. Update the hardware version to: V3.0. 5. There is no other change, The appearance, all RF parameters and circuits remain the same as before. SAR compliance for body-carry configurations is limited to provision at least 0 cm separation between the device and the user's body. The highest reported SAR values for the body-worn and simultaneous transmission use condition are < 0.1 W/kg and 0.25 W/kg at 1g tissues, respectively. |
