2.1 උපාංගය බල ගැන්වීම
The SMARTRO SC91 can be powered by a DC adapter (included) for continuous operation and display brightness, or by 2 AA batteries (not included) for backup power and portability. Batteries are primarily for memory backup during power outages.
- Insert 2 AA batteries into the battery compartment on the back of the main unit, observing polarity.
- Connect the DC power adapter to the main unit and plug it into a wall outlet. The display will light up.
2.2 Setting Up the Wireless Outdoor Sensor
The outdoor sensor transmits temperature and humidity data to the main unit.
- Open the battery compartment of the wireless sensor and insert 2 AA batteries, observing polarity.
- Select a channel (1, 2, or 3) on the sensor. The main unit will automatically search for the sensor.
- Place the outdoor sensor in a shaded area, protected from direct sunlight and rain, to ensure accurate readings and prolong its lifespan. The transmission range is up to 200ft/60m in an open area.

5. දෝශ නිරාකරණය
If you encounter issues with your SMARTRO SC91, refer to the following common problems and solutions:
| ගැටලුව | විය හැකි හේතුව | විසඳුම |
|---|---|---|
| සංදර්ශකයක් නැත හෝ අඳුරු සංදර්ශකයක් නැත | බලය නැත හෝ බැටරි අඩුයි. | Ensure DC adapter is properly connected. Replace AA batteries if running on battery power or for backup. |
| එළිමහන් උෂ්ණත්වය/ආර්ද්රතාවය ප්රදර්ශනය කර නැත හෝ නිවැරදි නොවේ. | Sensor out of range, low sensor battery, or interference. | Move sensor closer to the main unit. Replace sensor batteries. Avoid placing near large metal objects or electronic devices. Re-sync sensor by removing and reinserting batteries in both units. |
| Projection is blurry or unclear | Incorrect projection distance or focus. | Adjust the distance between the clock and the projection surface (optimal 5-13ft). Ensure the projection lens is clean. |
| Alarm not sounding or too quiet | අනතුරු ඇඟවීම සක්රිය කර නැත හෝ ශබ්දය ඉතා අඩුය. | Check if the alarm is enabled via the switch on the back. Ensure the alarm volume is set appropriately (if adjustable). |
| කාලගුණ අනාවැකිය වැරදියි | Initial setup or local atmospheric pressure changes. | The weather forecast is based on barometric pressure changes over time. Allow 7-14 days for the station to learn local atmospheric pressure. It predicts trends, not real-time weather. |
