3. Factory Settings
1. Remove the battery cover of weather station.
2. Insert the batteries, observing the correct polarity (" + " or" - ") (seeing marking)
3. Once the batteries are in places, all the icons in the LCD display will briefly light up for 3
seconds and a short signal tone will sound. Then the unit will take the measurement of
indoor temperature and humidity.
4. At this time, the station tends to receive the data signals from transmitters. It will take about
3 minutes until the blinking of RF antenna symbol located on the display area of transmitters
5. Now, it is turn to install batteries for outdoor wireless transmitters. Remove the cover of
battery compartment for outdoor transmitter, and insert the 2×AA batteries, observing the
correct polarity (" + " or" - ") (seeing marking) .
6. When the receiver gets data from transmitter, it will enter radio controlled time reception
mode.
1. Power the main unit first, and then outdoor transmitter. It is due to the fact that the main unit
tends to receive the data signal given off by the outdoor transmitter. The successful signal
reception should be done indoors prior to the mounting outdoor, preventing from the failure of
signal reception..
4. Reception of radio signal
2. For every restart of the Weather Station, it will search for radio signal automatically, lasting for
about 7 minutes, and radio icon will start to blink.
3. At 1 , 2, and 3 every night respectively, , the station will attempt to receive the WWVB time
signal to make time very accurate. If reception attempts have been unsuccessful, (no radio icon
shown in the LCD), the system will still attempt reception every an hour. But the total attempts

GBlife PT3378 Instruction Manual
will be up to 5 times. Whether successful or not, searching for WWVB time signal will be done at
1, 2, and 3 every night respectively. If successful at 3 am, no searching will continue at 4 am / 5
am. Otherwise, it will continue at 4 am, and so on. But anyhow the fifth is the final try.
4. Hold ▲key for two seconds to start manual reception of WWVB time signal. If no reception of
signal within 7 minutes, searching for WWVB time signal will be terminated, (no radio icon shown
in the LCD).
5. Press “▲” key once to terminate searching for signal.
Attentions
a. The blinking of radio icon indicates the start of WWVB time signal reception
b. Radio icon, always "on" in the LCD, indicates the successful reception of WWVB time signal.
c. The distance of the Weather Station or transmitters, it is suggested, should be at least 2.5
meters away from any interfering sources such as computer or TV sets. (Too much inference
will fail signal reception)
d. Radio signal is relatively weak in the room (such as basement or offices with concrete walls).
Under extremely unfavorable conditions, place the main unit at proximity of window to
better signal reception.
e. Display screen will be black out in radio signal reception mode (regardless of power supply
by adapter or other source). Press “▲” key for practical function. HOLD “▲” key to exit the
reception mode.

Q&A
Q：Why is LCD black out even if the Weather Station is powered through adapter ?
A: RCC function is active to synchronize time. During the process of signal reception, the product
enter sleep mode to avoid interference from other sources. LCD will light up when signal
reception is successful.
Q: No outdoor temperature and humidity shown in the unit ?
A1: Please check if the main unit and outdoor transmitter are in the same channel. No data will
be displayed in event of discrepancy;.
A2: Considering the failure of signal transmission by outdoor transmitter, update the signal
reception as following:
1）Hold “▼”key in the main unit for 3s to initial manual reception of signal from transmitter
2）Press “TX” key on transmitter to initial signal transmission to the main unit.
Q：Why are data of temperature and humidity inaccurate?
A：Temperature Error: ±1℃Humidity Error: ±5%.
