7. INSTRUCTION FOR USE
7.1 Instruction for charging and connecting
If
prompt displays on the LCD, please charge the scale with exclusive adaptor.
Locate adaptor plug on the rear side of indicator.
The battery should be recharged at least every 3 months regardless if it is used or not. After a long period
in storage, e.g. over 3 months, the battery should run a full cycle (charge/discharge) to allow it to restore to
full capacity.

The Hold function is used to accurately determine the average weight, also with unstable value (small
movements)
•switch-on the scale using the [ON/OFF] key. The display shows “0.0 kg” and the stable weight and zero
indications, after the self-test.
•Ask the patient to climb onto the weighing platform.
•Press HOLD. The display shows "HOLD" with a flashing triangle and then, after a few seconds, the average
weight value that remains permanently on.
•Press HOLD again to release the weight memorized on the display. The instrument goes back to normal
weighing mode.
•The HOLD function may be activated before or after the patient has climbed onto the platform.
7.1a RECHARGEABLE BATTERIES
ATTENTION!
For proper charging of the battery pack, connect the instrument to a power outlet for at least 8 hour

7.4 BMI FUNCTION
Press BMI in weighing mode. The secondary display shows the last set height, with
the left digit flashing.
Use the number keypad to enter the height (e.g.: 170 cm)
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.
8. PRINTER FUNCTIONS
Weight can be printed for records using RS232 interface cable. After weighing simply press PRINT key to
print out the results
