EMS COMBINATION 850 Manual page 21

The Display is used with the cursor keys to show and modify all the settings
and treatment parameters of the Combination 850. See the Operating
Instructions section for more information.
The Interferential Output Control sets the interferential output current or
voltage dependent on whether constant current or constant voltage mode is
selected. When the treatment time is not zero advancing the output control from
its off position will cause the treatment indicator to light and the interferential
treatment time to count down.
The Ultrasound Intensity Up and Down keys set the ultrasound output
intensity. When ultrasound is selected, the treatment time is not zero and a
suitable transducer is connected to the ultrasound output socket, pressing the up
2
key will increase the intensity by 0.1 W/cm . The ultrasound treatment
indicator will light whenever ultrasound is being generated by the transducer.
The Combination 850 will start to charge the internal battery whenever the
mains supply is connected and the mains switch on the front panel is in the on
position (mains indicator on). The battery charging indicator on the Control
Panel shows that the battery is being charged. When the battery is fully charged
the charging circuit is disabled and the battery charging indicator will turn off.
The Combination 850 uses rapid battery charging to minimise the charge time.
