Operational Mode
The light has three modes of operation:
Always on, Standby Mode and Dusk-to-Dawn
mode. These
modes can be selected either via the IR remote control or via the GSM module (if fitted).
In Always On mode, the daylight sensor is disabled and the lantern will remain ON.
In Standby mode, the lantern is turned off and the daylight sensor is disabled. This mode does not affect
the operation of the GSM module.
In Dusk-to-Dawn, the daylight sensor is enabled.
