U-Sensor Gateway Backup power
The USG includes an internal rechargeable battery.
The internal battery is used as backup power in case of short power outages.
The USG unit can operate for up to 9 hours without external power.
A built-in power save mechanism enables the USG to operate between 20-60
hours in a power saving mode, by delaying communication to the server until
the batteries have been recharged to an appropriate level.
If SIM status is changed while the Gateway is under operation, indication will
be observed only after the gateway is restarted.
It is required to recharge the USG batteries when the YELLOW LED (5) blinks
once per second.
