Yamaha YT-1100 Owner's Manual

It is recommended to tune your Yamaha YT-1100 piano at least twice a year to maintain optimal sound quality. However, new pianos may require more frequent tuning as they settle.
To clean the keys, use a soft, damp cloth with a mild soap solution. Avoid excessive moisture and never use chemical cleaners. Dry the keys immediately with a clean, soft cloth.
Maintain a stable environment with a humidity level between 40-50%. Use a dehumidifier or a piano-specific humidifier if necessary. Avoid placing the piano near windows or heating vents.
Check for debris or foreign objects between the keys. If the issue persists, it may require professional servicing to adjust or repair the action mechanism.
Moving a piano is complex and requires special equipment and expertise to avoid damage. It is recommended to hire professional piano movers for this task.
Use a soft, dry cloth to dust the piano regularly. For polished finishes, use a piano polish recommended by the manufacturer. Avoid using household cleaners or polishes.
Regular maintenance includes tuning, action regulation, voicing, and cleaning. These should be performed by a qualified technician at recommended intervals.
Improving room acoustics can be achieved by adding curtains, carpets, and furniture to reduce echo. Position the piano away from walls to allow sound to project evenly.
Check for loose objects on or inside the piano that may vibrate. If the issue persists, consult a technician to inspect the strings, soundboard, and other internal components.
Adjust the bench so your elbows are at a slightly downward angle when your fingers rest on the keys. This promotes good posture and comfort while playing.
