Note
• These specifications are subject to change without notice.
• This monitor is clinically investigated according to the requirements of ISO 81060-2:2013 (excluding pregnant and pre-eclampsia patients). In the
clinical validation study, K5 was used on 85 subjects for determination of diastolic blood pressure.
• IP classification is degrees of protection provided by enclosures in accordance with IEC 60529. This monitor and optional AC adapter are
protected against solid foreign objects of 12.5 mm diameter and greater such as a finger. The optional AC adapter HHP-CM01 is protected
against vertically falling water drops which may cause issues during a normal operation. The optional AC adapter HHP-BFH01 is protected
against oblique falling water drops which may cause issues during a normal operation.
• Operating mode is classification in accordance with IEC 60601-1.
