DO NOT operate the keys with pointed objects (pencils, pens, etc.). Damage to
keys resulting from this practice is NOT covered under warranty.
Th
is is the Power key. With the scale off, pressing this key will apply power to
the scale and turn on the display. If the scale is already on, pressing the key will
turn it off.
This is the Lock/Release key. Press and release this key to cause the weight,
height, and BMI to lock on the current values until the key is pressed again.
While the scale display is locked, the annunciator resembling a padlock will
turn on in order to denote that the weight is being held.
This is the Zero key. Press and release this key to reset the display to zero.
Note that when this key is pressed with weight on the scale platform, the
display will zero the weight up to 100% of the scale capacity. When the weight
is removed, the display will show a negative weight value. Press the Ö0Õ key
again to reset the display to zero.
This is the Enter key. It serves two purposes. First, during setup, pressing the
key will accept the current displayed setting of the parameter. Second, the
key is used to signal completion of the entry of data (in both setup and
operation) and causes the scale to process the data entered.
This is the BMI key. It is used to input the patient’s height and then to perform
the Body Mass Index (BMI) calculation. Note that the scale will not respond to
pressing the key unless the weight is stable.
On the apex scale, pressing this key once allows the operator to enter the
height of the patient (from the inline height rod) using the

keys to
increase or decrease to the correct height. After entering the patient’s height,
