Disinfectants are used in medical facilities such as hospitals, outpatient departments, care facilities, or also in food production and in canteens. Disinfectants contain ingredients that not only combat microorganisms, but can also attack surfaces.

High-quality materials are used for the UNIFY DECT Handsets to protect them in daily use. The UNIFY DECT Handsets are additionally protected by a surface coating against the effects of a number of commercially available disinfectants.

To test the effectiveness of the surface coating, a number of agents were tested during the product development with the surfaces of the UNIFY DECT Handsets. These tests range from several types of artificial hand perspiration (alkaline, basic) to olive oil or cream. Because to the special use of the OpenStage M3 models, they are also tested with drilling emulsion, for example.

These agents have been expanded to include skin disinfectants, hand care products and surface disinfectants in the latest OpenScape DECT Phone S5 / OpenScape DECT Phone SL5 handsets series.

With the OpenScape DECT Phone S5 and OpenScape DECT Phone SL5, only materials are used that have proven to be uncritical in these tests.

The following agents have been tested to obtain a representative selection:

Hand disinfectant

  • AHD 2000 - Dr. Hans Rosemann
  • Sterillium classic - Bode
  • Epicare disinfectant - Ecolab
  • Desdermann pure - Schülke
  • Spitacid - Ecolab


Skin care products

  • CIMO Sept - Dr. Fast
  • Samolind - Dr. Fast
  • Samtasan - Dr. Fast


Surface disinfection

  • Incidin Rapid - Ecolab


Care and cleaning instructions

  • Never dipp or spray liquids into/onto the DECT Handsets since any liquid penetrating can lead to malfunctions or destruction of the device.
  • If necesarry, clean the device (including the display) with a soft, slightly damp cloth.
  • Use either water or one of the above agents to moisten the cloth. These have been tested and proven to be harmless to the surfaces of the device. Other substances have not been tested and cannot be recommended. In particular, e.g. solvents, bleaches or abrasives can damage the surface.
  • These agents should be removed completely to avoid deposits.
