• Never jump on the scale, there may be a risk of injury and malfunction of the equipment.
• Do not hang on the handrail.
• The equipment must be used with the included AC adapter only.
• Do not insert or remove the AC plug by the cable.
• Do not place a finger into any gap or any hole of the equipment. You may be injured.
• Please use caution when adjusting the height rod to prevent injury.
• Please return the height rod to the storage position after completion of measurement.
• Please do not touch or lean on the height rod or the display during weighing as this will reduce accuracy.
