4. Setup
4.1 Powering the Main Unit
- Insert 3 AAA batteries (not included) into the battery compartment on the back of the main unit. Observe correct polarity (+/-).
- For continuous backlight and optimal performance, connect the included AC power adapter to the main unit and plug it into a standard electrical outlet.
Note: When powered by batteries only, the backlight will illuminate for 15 seconds after a button press to conserve power. The backlight remains continuously on when using the AC power adapter.

4.2 Remote Sensor Setup and Placement
- Open the battery compartment of the TX19 remote sensor and insert 2 AA batteries (not included), observing correct polarity.
- Place the remote sensor outdoors in a shaded, dry location, protected from direct sunlight and precipitation. Ensure it is within 200 feet (60 meters) of the main unit.
- The main unit will automatically attempt to connect with the remote sensor. If connection is not established, press and hold the "CH" button on the main unit to initiate a manual search for the sensor.

4.3 Atomic Clock (WWVB) Synchronization
The weather station is designed to receive the WWVB atomic clock signal for automatic time synchronization. This process typically occurs overnight.
- Ensure the main unit is placed in a location with good reception, away from electronic interference.
- Set the correct time zone using the "MODE" button and "UP/DOWN" buttons. The available time zones are AST(-4), EST(-5), CST(-6), MST(-7), PST(-8), AKST(-9), HST(-10).
- Enable or disable Daylight Saving Time (DST) as required for your region.
- Leave the clock plugged in overnight. It will automatically attempt to sync with the WWVB signal.
Note: The backlight may temporarily turn off during WWVB signal reception. If the atomic clock signal is not received, the time can be set manually.

6. Maintenance
6.1 Battery Replacement
- When the low battery indicator appears on the display, replace the batteries in the main unit (3x AAA) or the remote sensor (2x AA) as needed.
- Always replace all batteries in a set with new ones. Do not mix old and new batteries, or different types of batteries.
- Dispose of old batteries responsibly according to local regulations.
6.2 Cleaning
- Wipe the display and unit casing with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as these may damage the display or finish.
- Ensure the remote sensor remains free of dirt, dust, and debris for accurate readings.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | No power or dead batteries. | Ensure AC adapter is plugged in or replace AAA batteries. |
| Outdoor temperature/humidity not displayed. | Remote sensor not connected or out of range. | Replace remote sensor batteries. Move sensor closer to main unit. Press and hold "CH" button on main unit to re-establish connection. |
| Atomic clock not synchronizing. | Poor WWVB signal reception or incorrect time zone. | Ensure correct time zone is set. Move unit to a location with better signal reception (e.g., near a window, away from electronics). Allow overnight for synchronization. Manual time setting is an alternative. |
| Inaccurate temperature/humidity readings. | Sensor placement or interference. | Ensure remote sensor is in a shaded, dry area. Avoid placing sensors near heat sources, vents, or direct sunlight. Allow time for readings to stabilize after placement. |
| Backlight not staying on. | Unit is running on battery power only. | Connect the AC power adapter for continuous backlight. |
