Upon first power-up or after a prolonged power disconnection without battery backup, the clock display may flash. Refer to Section 4.1 for detailed instructions on setting the current time and date.
4. Operating Instructions

4.3 Sleep & Awake Time Settings (Grow Children's Clock Trainer)
Addo uses visual cues to teach children when it's time to sleep and wake up:
- Bedtime Preparation: Approximately 30 minutes before the set bedtime, Addo's light will glow yellow, signaling to your child to begin preparing for sleep. The owl's eyes may display a sleepy expression.
- Sleep Time: At the set bedtime, the owl's eyes will close, and the lights may dim or turn off, indicating it's time for sleep.
- Quiet Play Time: Approximately 30 minutes before the set wake-up time, Addo will glow blue, signaling your child can play quietly in their room. The owl's eyes may still be closed or partially open.
- Wake-Up Time: At the set wake-up time, the owl's eyes will open, and the light will change to a bright color (e.g., blue), indicating it's time to get up.
