Confirm with
Press HOLD to lock the value. Climb onto the weighing platform when the display
shows "HOLD" and weigh yourself. The scale shows the weight, height and BMI
index.
Press BMI again to release the memorized weight and go back to normal operation
mode.
7.5 TARE FUNCTION
This function allows displaying two weights. Switch-on the instrument using the key .
When the display indicates and a beep is emitted, position the objects (clothing) constituting
the tare, onto the weighing platform.
With the weight stable and the appearance of the stable symbol (circle), press and the display shows
. Ask the patient to climb onto the platform. The indicated weight represents the tare's net
value. Delete the memorized tare value by climbing down from the instrument and press again.

Waste disposal EU 2002/96/EC
This product complies with the EU Directive 2002/96/EC. The symbol of the crossed-out waste bin on the
appliance indicates that the product, needing to be treated separately from household waste, at the end of
its useful life must be completed in a separate collection facility for electric and electronic appliances or
returned to the dealer upon purchase of a new equivalent appliance. The user is responsible for bringing the
appliance to an appropriate collection structure at the end of its life. Appropriate separate collection and
sending the appliance for recycling, treatment and environmentally compatible waste disposal contributes to
avoid possible negative effects on the environment and health and favours the recycling of the materials the
product is made of.
For more detailed information regarding available collection systems, contact your local waste disposal
service or the shop where the product was purchased.
As consumers, you are obliged by law to return used or dead batteries. You may deposit old batteries at
public collection spots in your town or else with any battery dealer who has placed specific collectors for this
