Ramp-up time, expressed in s, defines the time in a surge program during which the current is increased
from 0 to the adjusted level. See fig 4.1.4.13 for details. The ramp-up time can be adjusted in increments
of 0.1s.
Hold time, expressed in s, defines the time in a surge program during which the current is kept at the
adjusted level. See fig 4.1.4.13 for details. The hold time can be adjusted in increments of 1s.
Ramp-down time, expressed in s, defines the time in a surge program during which the current is
decreased from the adjusted level to 0. See fig 4.1.4.13 for details. The ramp down time can be adjusted
in increments of 0.1s.
Interval time, expressed in s, defines the time in a surge program during which the current is kept at 0.
See fig 4.1.4.13 for details. The interval time can be adjusted in increments of 1s.
Delay time, expressed in s, defines the time delay between the start of the surge program on channel 1
and channel 2. See fig 4.1.4.13 for details. The delay time can be adjusted in increments of 0.1 s.
Beep, if enabled, generates a short beep at the start of each surge.
9 Maintenance and Troubleshooting
9.1 Cleaning and Disinfection
9.1.1 Cleaning of apparatus
To clean the unit, turn it off and unplug the power supply. Clean the unit with a damp cloth. Do not use
abrasive cleaners. A small amount of mild household detergent may be used, if needed.
9.1.2 Cleaning display panel
Use a soft and dry cotton cloth or micro fiber tissue to clean the panel. To remove fingerprints or grease,
use a non-abrasive glass cleaning agent. Apply a small amount of the cleaning agent to a soft cotton
cloth and then carefully clean the panel.
CAUTION:
• Do not spray the cleaning agent directly on the glass panel.
• Do not use cleaning agents that contain strong alkalis, lye, acid, detergents with fluoride or
detergents with ammonia.
9.1.3 Electrodes and accessories
Between patient uses, the rubber electrodes should be cleaned with lukewarm water. To disinfect the
electrodes or to remove stubborn stains of dirt, use a 70% alcohol solution. The alcohol solution can
cause the black color to be stained, but this does not affect the operation of the electrodes.
Between patient uses, the sponge pads should be washed in warm water, using a household cleaning
agent. After washing they must be rinsed with clear water, thoroughly drained and then dried. Damaged
sponge pads should be replaced.
9.1.4 Patient cable
Clean the patient cable with a damp cloth. Use lukewarm water and a non-abrasive household cleaning
agent. Do not use an alcohol solution. Check the cable regularly for damages and/or bad electrical
contact. We advise, keeping a spare patient cable in stock.
9.1.5 Ultrasound applicator
To prevent corrosion, clean and dry the contact surface immediately after use. Make sure that no
ultrasound gel remains on the applicator. We further recommend cleaning the applicator and cable daily,
using lukewarm water. The applicator can be disinfected using a cloth moistened with a 70% alcohol
solution. Check the applicator and cable regularly for damage.
