1. Power On/Off
To turn the unit on or off, gently touch the designated power sensor. The projector will begin its operation or shut down accordingly.
2. Adjusting Volume
The volume of the lullabies can be adjusted to three different levels. Use the 'VOL' touch sensor to cycle through the volume settings until the desired level is reached.
3. Setting Playback Time
The projector offers adjustable playback times of 5, 10, or 15 minutes. Touch the corresponding timer button (5min, 10min, 15min) to select the desired duration for the projection and music.

4. Sound Activation (VOX Function)
The BC-125 features a sound activation function. When a sound is registered, the projector will automatically turn on for 5 minutes. To prevent false activations (e.g., from a door closing), the sound activation is triggered only by sustained tones at a specific volume level for a few seconds.
5. Projection and Music
The projector displays colorful images on the wall or ceiling, accompanied by soothing sleep songs. The most sleep songs will change automatically. The projected colors are typically white, blue, colorful, orange, and green, providing a calming visual experience.

Maintenance
To ensure the longevity and proper functioning of your Alecto BC-125 projector, follow these simple maintenance guidelines:
- Cleaning: The unit is made of Polyvinyl Chloride (PVC). Wipe the exterior surfaces with a soft, dry, or slightly damp cloth. Do not use abrasive cleaners or solvents, as these may damage the finish.
- Battery Replacement: When the projection or sound quality diminishes, it is an indication that the batteries need to be replaced. Always replace all three AA batteries at the same time with new ones.
- Storage: If the projector will not be used for an extended period, remove the batteries to prevent leakage and store the unit in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Projector does not turn on. | Batteries are dead or incorrectly installed. | Check battery polarity. Replace with new 3 x 1.5V AA batteries. |
| No sound or distorted sound. | Volume is too low or batteries are weak. | Increase volume using the 'VOL' button. Replace batteries if necessary. |
| Projection is dim or unclear. | Batteries are low. Room is too bright. | Replace batteries. Ensure the room is sufficiently dark for optimal projection. |
| Sound activation (VOX) triggers too easily or not at all. | Ambient noise level. | The VOX function is designed to activate with sustained sounds. Ensure the environment is not excessively noisy for false triggers, or that the sound is loud enough to activate it. |
