Cleaning The Electrodes, Leadwires, And Patient Data Cable; Safety Tests - HP PageWriter XL M1705B Service Manual

Cleaning the Electrodes, Leadwires, and Patient Data Cable
Clean the electrodes, leadwires, and patient data cable with a soft
cloth moistened with soapy water. You also can use a disinfectant or
cleaning agent such as CetylcideQ, Cidex@, Lysol@, Wescodyne@,
or Ves-phene@. Wring any excess moisture from the cloth before
cleaning.
