53.1 Wiring the SystemConnect the Rain Sensor and Wind sensor cables to theirrespectively marked jacks in the Thermo-Hygro sensor BEFOREpowering up the Base Station or the Thermo-Hygro Sensor.The Thermo-Hygro Sensor and Base Station can bedirectly connected via cable if the wireless 433 MHzradio transmission is not desired, and/or datatransmission free of localized radio interference is animportant factor.3.2 Power SupplyPower can be supplied to the Weather Center using batteries orthe AC adapter. In the case that the AC adapter is used, it willprovide all required power to the system if the Base Station andThermo-Hygro Sensor are wired directly together.3.2.1 Use Batteries for Power:- First insert two Type C alkaline 1.5 V batteries into thebattery compartment of the Thermo-Hygro-Sensor.- Immediately after, insert three Type AA alkaline 1.5 Vbatteries into the battery compartment of the Touch ScreenBase Station.3.2.2 Use AC Adapter for Power:- First insert two Type C alkaline 1.5 V batteries into thebattery compartment of the Thermo-Hygro-Sensor.- Immediately after, connect the AC adapter to the BaseStation, and then plug it into an AC outlet.- When the AC adapter is used, batteries may also be placedin the Base Station to serve as a backup power supply ifthere is a power outage.Note: In either case, it is important to observe this order ofsuccession because the Sensor will send an identificationcode that must be received and stored by the Base Stationwithin the first few minutes of operation.
