7. Power Consumption
•
The default power consumption when not connected to Access-Point is 246mA at average
operational condition and 252mA at peak operational condition.
•
The default power consumption when connected to Access-Point is 256mA at average
operational condition and 264mA at peak operational condition.
•
Power consumption during Google Cast for Audio (GCast) play back is 272mA at average
operational condition and 358mA at peak operational condition.
8. Environmental
8.1. Storage Conditions
The calculated shelf life in a sealed bag is 12 months if stored between 0°C and 70˚C at less than 90%
relative humidity (RH).
After the bag is opened, devices that are subjected to solder reflow or other high temperature
processes must be handled in the following manner:
•
Mounted within 168 hours in factory conditions, i.e. <30°C at 60% RH.
•
Storage humidity needs to maintained at <10%RH.
•
Baking is necessary if the customer exposes the component to air for over 168 hrs.
- Baking conditions: 125℃ for 8hrs.

FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
This modular must be installed and operated with a minimum distance of 20 cm between the radiator
and user body. If the FCC identification number is not visible when the module is installed inside
