2. PUTTING INTO OPERATION
■ Installing the scale elements
The indicator's placement must allow for a simple
disconnection from the power supply.
Insert rechargeable batteries in all four weighing
devices. When the batteries are fitted, the weighing
devices start to send and attempt to set up a radio
link to the digital indicator.
Caution (Fig 1–4 right):
Before switching on the scale, place the weighing
devices under the four wheels of the hospital bed.
Push the weighing devices as far as the stop under
the wheels. Press the lever down and raise the bed
wheel. (The weighing devices are designed to receive wheel diameters of 130–160 mm. Small diameters are optional.)
The message "SOEHNLE PROFESSIONAL" appears in
the indicator display together with a search icon until
■ Power-on / Power-off
Switch on or off the digital indicator
by pressing the On/off switch.
the radio link is set up to the weighing devices. This
normally takes 20 to 60 seconds.
When the radio link to the weighing devices is set
up, the indicator display shows the current gross
weight value.

■ Radio link
The Bluetooth radio link operates over a max. radius
of 5m if there is no partition wall between the weighing devices and the digital indicator. After short interruptions (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.
OFF display
When the scale is switched off but remains connected
to the power supply, the indicator display shows
"OFF" (in accordance with the Medical Equipment
Directive).
■ Charging the batteries
Open the cover of
the battery charger.
The charger has
four compartments
to recharge the four
batteries simultane-
ously. The four LEDs
indicate the charge state for each battery. The fifth
LED on the charger is the mains power indicator for
the charger itself.
LED status indicator on charger (for each charge
compartment):
• LED lights up orange: battery still charging
• LED lights up green: battery charged – trickle
charge
LED status indicator on weighing device:
Digital indicator is switched on (radio link active)
• LED lights up green: battery charged
• LED flashes green, mainly on, off for short
periods: battery still has sufficient capacity
for normal operation
• LED flashes green, normally off, only on for
short period : battery almost empty, battery
must be recharged
Digital indicator is off or in standby mode
• LED lights up green for approx. 2 mins
and then starts to indicate standby mode
by flashing (mainly off)
The charging time for empty batteries is approx. 4
hours. Batteries should be charged and exchanged
in sets. The batteries may remain for any length of
time in the charger when it is on.

Display of link state:
Press Info key + 1. The following appears in the
indicator display:
Weighing device State Battery voltage
1: 0080025005BB7 OK 6.3 V
2: 0080025005C0D Error
3: 0080025005C70 OK 6.3 V
4: 0080025005ADC OK 6.3 V
Charge run time:
A battery charge is sufficient for approx. 12 hrs continuous duty. When the scale is switched off for most
of the time (90% OFF), the batteries may remain in
the weighing devices for up to 125 hours before they
require a recharge.
Caution: Even when the digital indicator is switched
off, the Bluetooth link is activated at regular intervals. For this reason, the batteries will discharge in
this state and must be recharged at the latest after
125 hours.
Recommendation:
Always remove the batteries from the weighing devices after you switch off the digital indicator and
place them in the battery box of in the charger.
This makes sure that the scale works reliably the
next time it is switched on.
If the bed scale remains without use, remove the
batteries from the weighing devices to prevent
deep discharge. The scope of supply comprises
eight batteries.
