■ Radio link
The Bluetooth radio link operates over a max. radius
of 5m if there is no partition wall between the weig-
hing devices and the digital indicator. After short inter-
ruptions (e.g. to replace a battery or caused by the
loss of battery contact due to shocks), the link is
restored automatically within a few seconds. During
connection process appears the following symbol .
■ Power-off
If the sensors are overloaded or you
have started a menu, the scale swit-
ches off after you press the On/Off
button for 5 seconds.
It is not possible to switch off the sca-
le as long as it is waiting for an input in the editing
section of Setting mode. First exit the editing section
before switching the scale off.
The weighing devices have no on/off switch. They are
only switched off when the batteries are removed.
