9 Maintenance and Troubleshooting

9.1

User Maintenance

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.
To disinfect the unit we advise to use Dismozon® pur. in a solution between 0,25 and 1,5%
9.1.2

Cleaning display panel

The display panel contains an anti-reflective coating, which needs special care when cleaned. Use a soft
and dry cotton cloth or micro fibre 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.
•
Use no liquid detergents, these can damage the apparatus.
9.1.3

Ultrasound applicator

To prevent corrosion, clean and dry the contact surface immediately after use. Make sure that no
ultrasound gel remains on the applicator.
To disinfect the treatment applicator we advice to use Dismozon® pur. in a solution between 0,25 and
1,5%. This product can be ordered at Enraf-Nonius under the number 3442438.
We further recommend cleaning the applicator and cable daily, using lukewarm water. Check the
applicator and cable regularly for damage.
9.2

Troubleshooting

9.2.1

Error code

When the apparatus is turned on, it will first execute a self test. When an error is detected, both during the
self test and during normal operation, a pop-up screen will appear on the display. When the error is
displayed, all outputs will be disabled. When this situation occurs, remove all cables and switch the
apparatus off and on again. When the error re-appears, stop using the device and contact your supplier.
If none of the above scenarios appear to be the problem, stop using the device and contact your supplier.
9.3

Technical Maintenance

On request a service manual can be made available containing: spare part list, descriptions, calibration
instructions and other information which will assist the user's appropriately qualified technical personnel
to repair those parts of the equipment which are designated by the manufacturer as repairable.
CAUTION:
•
Electrical safety of the device relies on a proper earthed electrical connection via the power cord.
It is therefore necessary to have this connection checked annually.
•
To ensure continued compliance with the 21 CFR 1050.10 standard, this unit should be adjusted
and safety tested once each year. Procedures laid down in the service manual should be
followed. This may be carried out by your supplier, or by another agency, authorized by the
manufacturer. It is also recommended that a service history record is maintained. In some
countries this is even obligatory.
•
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous exposure to ultrasonic energy.
