SOLAR-POWERED TRANSMITTER OPERATION MODES
(1) NORMAL MODE:
NORMAL MODE occurs when the battery voltage is 2.5V or greater.
It measures and transmits temperature data to the indoor receiver every 8 seconds.
It checks the brightness level of the surrounding environment every 5 seconds.
It measures / transmits every 16 seconds if it detects a dark environment or if the battery
voltage drops below 2.5V.
(2) IDLE MODE:
If the battery voltage drops below 2.4V, it commences IDLE MODE; the LCD turns off and it
does not measure / transmit weather data.
It checks the brightness level of the surrounding environment every 5 seconds.
If battery voltage rises back to 2.5V or above, it returns to NORMAL MODE.
If the environment remains dark for 72 hours, it commences STOP MODE.
(3) STOP MODE (STANDBY):
Occurs when the environment remains dark for 72 hours OR if you manually commence
STOP MODE (standby) by covering the solar cell for 10 seconds and then press the RESET
key one time.
NOTE: The LCD will display "StP" then turn off and commence STOP MODE.
While in STOP MODE (standby), the LCD is off and the Sensor does not perform any normal
operations.
To resume normal operation, ensure the Sensor is in a bright environment (next to a 60W
light bulb or similar condition) and press the RESET key to return to NORMAL MODE (battery
voltage is higher than 2.5V).
SOLAR MODE ON THE WEATHER STATION
This weather station has green technology and a power-savings mode that reduces power consumption
by monitoring and reacting to available lighting conditions.
The surrounding environment brightness is checked every 5 seconds.
LCD will automatically turn OFF if the environment is too dark. (It will appear blank)
LCD will automatically turn ON if the environment is bright enough.
No information will display when the LCD is OFF, but all the settings and operations will
remain, except for the temperature measurements.
NOTE: This will occur no matter which type of battery you use. This is a Program Menu
feature.
Turn this feature off and the LCD will stay on all the time. Enter the Program Menu and click
through until you see SOL and ON flashing. Press the PLUS button to turn Solar Mode OFF.
The LCD will no longer go blank in low light situations.
STOP MODE ON THE WEATHER STATION
If the Weather Station is in a dark environment for 72 hours continually, the clock will go to the stop mode:
The most power saving condition.
The indoor solar display will not operate and the LCD will turn OFF.
Press any key to wake up the indoor solar display and re-activate the transmission with the
solar transmitter.
