The Medisana BS 444 connect is a body analysis scale designed for private household use, offering comprehensive body composition measurements and seamless data transfer to a smartphone app via Bluetooth.
Function Description
The primary function of the Medisana BS 444 connect is to provide detailed body analysis measurements. It operates on a "Step-On" function for simple weight measurements, where users simply stand barefoot on the scales, and their weight is displayed. Beyond basic weight, the device measures several key body composition parameters:
- Weight: The user's total body mass.
- Proportion body fat: The percentage of body mass that is fat.
- Proportion body water: The percentage of body mass that is water.
- Proportion muscle mass: The percentage of body mass that is muscle.
- Bone mass: The total mass of bones in the body.
- BMR (Basal Metabolic Rate): The number of calories required to keep the body functioning at rest.
- BMI (Body Mass Index): A measure that uses height and weight to determine if a person is underweight, normal weight, overweight, or obese.
The scale can store personal data for up to 8 people, with each user having up to 30 memory locations for their measurements. This allows for tracking progress over time. User recognition is automatic, based on the last measurement. If two users have similar weights, the scale will prompt the user to select the correct profile (P1 to P8).
A key feature is its connectivity with the VitaDock+ app via Bluetooth® 4.0 or Bluetooth Smart®. This enables users to transfer their measurement data to their smartphone or tablet, allowing for long-term tracking, analysis, and management of their health data. The app requires iOS (iPhone 4S and later, iPad 3 and later) or Android (Version 4.3 Jelly Bean) and a stable internet connection for registration and data synchronization.

Usage Features
- Simple "Step-On" Function: For basic weight measurement, users simply step onto the scale barefoot.
- Personal Data Settings: Users can set their gender, athletic condition, height, and age directly on the scale. This information is crucial for accurate body composition analysis.
- Automatic User Recognition: The scale attempts to automatically identify the user based on previous measurements. In cases of similar weights between users, it prompts for manual selection.
- Barefoot Measurement: For accurate body fat analysis, users must stand barefoot on the electrodes.
- Consistent Measurement Conditions: For reliable results, it is recommended to weigh oneself under the same conditions, at the same time of day (preferably in the morning, after showering or bathing), standing still and straight, and with dry feet.
- VitaDock+ App Integration: The app allows for a comprehensive overview of health data, including weight, body fat, body water, muscle mass, and calories. It facilitates long-term tracking and analysis of trends.
- Guest Mode (P0): Allows for measurements without saving data, useful for temporary users. However, data from guest mode cannot be transferred via Bluetooth.
- Error Messages: The scale provides error messages, such as "P1P2" or other memory location combinations, to indicate when multiple users have similar weights, requiring manual selection.
Maintenance Features
- Battery Replacement: When replacing batteries, observe the correct polarity (+/-) and use only the same or equivalent type (3x AAA, 1.5 V).
- Battery Protection: Protect batteries from excessive heat. Remove expired batteries or when the device is not in use for extended periods to prevent leakage and damage.
- Cleaning: Do not use strong chemicals, aggressive, or foaming cleaning materials. The surface should be kept dry, as it can be slippery when wet or damp.
- Moisture Protection: Protect the device from moisture and keep it away from water.
- Environmental Protection: Do not keep the scales in hot surroundings or expose them to strong sunlight.
- Physical Protection: Protect the scales from any impact or shaking. Do not make any changes to the scales or open them up. Repairs should only be carried out by a specialist workshop or service center.
- Placement: Place the scales on a non-slip, non-yielding base if the floor is coated with materials that might attack or soften the device's feet.
- App Updates: Medisana recommends periodically updating the VitaDock+ app for continuous product optimization and improved functionality.
- Private Household Use: The device is intended for private use only.
- Weight Limit: Not to be used by individuals weighing over 180 kg.
- Pregnancy: Not to be used during pregnancy.
- Medical Implants: Not to be used by individuals with heart pacemakers or other medical implants due to the electrical current used for body fat analysis.
- Children: Body fat analysis is not recommended for children for safety reasons, though children can be weighed. Keep batteries and the device out of reach of children to prevent accidental swallowing.
- Slipping Hazard: Never step onto the scales with wet feet or while wearing socks. Always stand still in the middle of the scales, ensuring each foot touches two electrodes. Place the scales on an even surface.
- Damaged Device: Do not use the device if it is not functioning perfectly, has fallen into or under water, or has been damaged.
