When you step on the scales, barefoot, an electric current of very low intensity is transmitted through the body via the electrodes. This current, which travels from one foot to the other, encounter difficulties when it has to pass through fat. This resistance of the body, called bioelectrical impedance, varies according to gender, age and height of the user, and makes it possible to determine body fat. This device is perfectly safe because it operates with a very low current (4 x 1.5 V batteries).
To be fully satisfied with this appliance, measuring and weighing must always be conducted under the same conditions: • Always weigh yourself in bare feet. Your feet must be dry and properly positioned on the electrodes. Beware that if your feet have too much hard skin the measurement may be affected. • preferably once a week first thing in the morning, • 1/4 of an hour after waking up, so that the water in your body is distributed in the lower limbs. It is also important to ensure that there is no contact between the legs (thighs, knees, calves) or between the feet. If necessary, slip a sheet of paper between your legs.
We recommend always using new alkaline batteries (LR03 batteries), and never using saline batteries (R03 batteries) or rechargeable batteries (HR03 batteries). When changing the batteries, always replace all batteries with new alkaline batteries. This does not apply to scales using CR2032 button batteries or lithium batteries.
During the bathroom scale manufacturing calibration some variations could appeared from one scale to another. Some differences coming from these variations could appear if you compare your weight on two different bathroom scales.
It is normal for the "8888" message to be displayed when batteries are inserted. The product is in the initialisation phase. Place it on a flat surface and wait for the message to clear. Moving or stepping on it while “8888” is displayed will restart initialisation. Initialisation can take from 5 to 30 seconds.
The virtual keyboard is only activated once weighing is complete. Here are the rules to follow: • Step off the product once weighing is complete, • The product must remain on the ground when tapping the keys, • Only tap the keys with one finger, • Only use a finger to tap the keys (no objects).
