User Manual Tefal PP7049A9 Tendancy glass Scale

It is important to always weigh yourself at the same time of day. The best frequency is once per week.

This function allows an immediate weight display. It is not necessary to wait for the "0" to display - the weight calculation begins immediately.

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.

Most of the recent bathroom scales have a switch on the battery location if not, look at the instruction manual.
