3 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.)
■ Power-on / Power-off Switch on or off the digital indicator by pressing the On/off switch.
4
The message "SOEHNLE PROFESSIONAL" appears in the indicator display together with a search icon until 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.
7
ENGLISH Bed scale 7711
■ 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.
■ Power-off If the sensors are overloaded or you have started a menu, the scale switches off after you press the On/Off button for 5 seconds. It is not possible to switch off the scale 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 simultaneously. 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 1: 0080025005BB7 2: 0080025005C0D 3: 0080025005C70 4: 0080025005ADC
State OK Error OK OK
Battery voltage 6.3 V 6.3 V 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 for long period of time without use, remove the batteries from the weighing devices to prevent deep discharge. The scope of supply comprises eight batteries.

5. FUNCTIONS ■ Power-on zeroing
■ Weighing and taring
During the power-on procedure, the weight values sent by the weighing devices are zeroed until they are less than 50% of the max. weighing range. This tares the empty bed and the weight display goes to zero.
Display view
■ Manual zeroing Manual zeroing corrects minor deviations from zero, e.g. caused by soiling on the scale. The following character appears in the icon bar when the display indicates zero: >0<. Zero range approvable and non-approved: 1% to +3% of the weighing range. If zeroing is not possible, the error message "Value above zero range limit" or "Value below zero range limit" appears for two seconds in the display.
■ x10 (times 10) display Shows the weight value with an additional decimal place at ten times the resolution. Switch to the x10 display by pressing + ENTER and then the ZEROING key simultaneously. According to the calibration law, the x10 function may only be activated on approvable scales for a short period of time. For this reason, it s programmed so that the function is switched off automatically after 5 seconds. The message x10 appears in the icon bar as long as the 10-time higher display is selected. When the appliance is switched off, the function is deactivated.
■ Weighing with measured tare Determine and tare a bed weight without patient. Position the empty bed, including bedding, on the scale. Press the TARE key.
