- When you insert the batteries, all the icons on the LCD display will briefly light up for 3 seconds, and you will hear a beep tone, and detect indoor temperature & humidity.
- The Weather Station will now start to make a connection to the remote sensor. This operation takes about 3 minutes and is displayed by a flashing reception RF antenna symbol in the “REMOTE SENSOR” display area on the receiver.
- This now, replace Wireless Remote Sensor battery compartment cover, Open Weather Station battery compartment cover, Insert 2 x AA batteries observing polarity [ “+” and “–“ marks]
- After the receiver has created a connection to the remote sensor, it will then enter the Radio control time receive mode.
Reception of the Radio signal:
- The clock automatically starts the WWVB signal search after 7 minutes of any restart or changing of new fresh batteries. The radio mast icon starts to flash.
- At 1:00 /2:00 / 3:00 am, the clock automatically carries out the synchronization procedure with the WWVB signal to correct any deviations from the exact time. If this synchronization attempt is unsuccessful (the radio mast icon disappears from the display), the system will automatically attempt another synchronization at the next full hour. This procedure is repeated automatically up to a total of 5 times.
- To start manual WWVB signal reception, press and hold down the “▲” button for two seconds. If no signals are received within 7 minutes, then the WWVB signal search stops (the radio mast icon disappears) and starts again at the next full one hour.
- During RC reception to stop searching radio signal, press the “▲stop” button once.
F.Y.I.:
- A flashing radio mast icon indicates that the WWVB signal reception has started
