*Battery Life and Power Supply

The product will arrive partly charged, but ideally you should charge it for 24 hours before use for optimum performance. The battery can be recharged (unit must be between 0°C to +40°C / +32°F to 104°F) via a PC, a USB +5V wall adapter RF320 (UK/US), or a portable USB battery pack using the USB lead provided. It can also be permanently powered by the RF320 USB wall adapter. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect.

Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature.

For more information on Battery and WiFi Considerations please read our Product Information Bulletin for RF300.
