Operating Instructions
Basic Functions
- START/STOP Button: Press to turn the air conditioner ON or OFF.
- MASTER CONTROL: Cycles through operating modes such as Auto, Cool, Dry, Fan, and Heat.
- FAN CONTROL: Adjusts the fan speed (e.g., Auto, Low, Medium, High).

Green Backlight Feature
The remote control features a green backlight for improved visibility in low-light conditions. This backlight activates automatically when buttons are pressed, making it easier to operate the air conditioner at night.
Advanced Heat Functions (If Applicable)
Some Fujitsu AC models support advanced heat functions such as "10°C HEAT", "50°F HEAT", "MINI.HEAT", or "ECONOMY". These functions are only available if your original remote control also had these specific buttons or capabilities. To activate these, you may need to press and hold a specific button for approximately 4 seconds. Consult your air conditioner's original manual for specific details on these functions.

Maintenance
Cleaning the Remote Control
To clean the remote control, use a soft, dry cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the remote's surface or internal components.
Battery Replacement
Replace the batteries when the remote control's range decreases, or if the display becomes dim or unresponsive. Always replace both batteries at the same time with new AAA batteries. Do not mix old and new batteries, or different types of batteries.
If the remote control will not be used for an extended period, remove the batteries to prevent leakage and potential damage.
Troubleshooting
Remote Control Not Responding
- Check Batteries: Ensure batteries are inserted correctly with the correct polarity (+/-). Replace with fresh AAA batteries if necessary.
- Line of Sight: Make sure there are no obstructions between the remote control and the air conditioner's receiver.
- Distance: Ensure you are within the effective operating range of the air conditioner's infrared receiver.
- Infrared Interference: Strong light sources (e.g., direct sunlight, fluorescent lights) can interfere with the infrared signal. Try operating the remote in a different lighting condition.
Display Issues
- Dim Display: This usually indicates low battery power. Replace the batteries.
- No Display: Check battery installation and ensure batteries are fresh. If the issue persists after replacing batteries, the remote may require service.
Functions Not Working
- Compatibility: While this remote is broadly compatible, some advanced functions might not be supported by all Fujitsu AC models, especially if your original remote did not have those specific features.
- AC Unit Status: Ensure your air conditioner unit is powered on and functioning correctly.
