2.2 Selecting Melodies
The Seiko NR435P features 31 different melodies for its alarm function. These can be selected in three patterns:
- Daily Rotation: The clock can play a different melody each day of the month.
- Mood-Based Selection: Choose a pattern that suits your mood.
- 好きな曲: Set the alarm to play a specific, preferred melody.
Refer to the controls on the front of the clock (Figure 4) to cycle through melody options and select your desired pattern. The specific labels for these controls may be in Japanese, but typically involve a button or switch to advance through songs or modes.
