2 Basic Information (General) These body fat balance are designed for the determination of body fat, water content, muscle ratio and bone weight according to the so-called impedance method. This method is applied to determine the resistance value of the human body with the help of electrical impulses. A high fat ratio in the body will for instance increase the resistance value. For individual calculations, it is possible to store basic data (such as body height, age and gender) for up to 10 persons.
2.3 Warranty Warranty claims shall be voided in case Our conditions in the operation manual are ignored The appliance is used outside the described uses The appliance is modified or opened Mechanical damage and damage caused by media, liquids Natural wear and tear The appliance is improperly set up or incorrectly electrically connected The measuring system is overloaded Dropping the balance 3 Basic Safety Precautions 3.
- Place the balance on a firm, level surface; - Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or in the direct sunlight; - Protect the balance against direct draughts due to open windows and doors; - Avoid jarring during weighing; - Protect the balance against high humidity, vapours and dust; - Do not expose the device to extreme dampness for longer periods of time.

TBW Display: Body water ratio in % MUS Display: Muscle ratio in % BONE Display: Bone weight in kg You can change the scale’s weighing unit from “kg“ to “lb“ at the rear of the balance. When changing the weighing unit to lb you must enter the body height in ft. 7 Using the balance To switch on balance, press one of the 3 keys. Display unit “PX“ (X may be selected from 0 to 9) starts to flash. To select a different digit, press the arrow key up or arrow down.
d. When age starts to flash, this too, can be changed by pressing the arrow keys. Complete your data entries by pressing SET. After these entries have been made, the display will show “_ _ _ _“ for a short while. Afterwards 0.0 kg will be displayed and the balance are ready for weighing. When the balance are not in use they automatically switch off after a short time. 7.2 Usage as body fat balance After having carried out the previous settings the balance will be ready for operation.
On top of this, the bottom line on the display will show an evaluation of the body fat ratio in words. Displayed words indicate the following: Underfat = body fat ratio too low Healthy = body fat ratio optimal Overfat = body fat ratio too high Obese = person tending towards obesity d. The display will after a short while switch over to the percentage value for body water ratio ( TBW ) e. Afterwards the display will switch over again in order to show the percentage value for body muscle ratio ( MUS ) 6.

8 Error message Messages can be displayed when the balance are switched on or in operation. ERR 1: Weighing range exceeded ERR 2: Measuring started without a barefoot person present on weighing plate. Lo : Batteries are run down ----- : Load was present on weighing plate when started After the load was taken off the weighing plate, the display will again show "- ----„. 9 Service, maintenance, disposal 9.
10 Instant help In case of a fault in the program sequence, the balance should be shortly switched off. The weighing process must then be restarted from the beginning. Help: Fault Possible cause The displayed weight does not glow. • The balance is not switched on. • • Batteries are inserted incorrectly or empty No batteries inserted. • Draught/air movement • • Table/floor vibrations The weighing plate is in contact with foreign bodies or is not correctly positioned.
