How do I change the scale units from kilograms (kg) to pounds (lb) on the Compella™ Bariatric Bed?
 

The default units shown on the scale display is kilograms (kg). To change the units to pounds (lb), do as follows:

1. Make sure the Enable key indicator is off

2. Press and hold the Zero control. 

After approximately five seconds, as you continue to press the Zero control, press and hold the Weigh control. When you hear a beep, release both controls. The display will be in configuration mode with the current unit setting highlighted: lb or kg.

3. Press and release the Scale Weigh control to move through the settings.

When you reach the applicable setting,  release the control and wait until you hear a beep (approximately ten seconds). The display will store the new configuration and exit the configuration mode.
