Prepare following items before manual cleaning and disinfection:
a) Detergent: Cidezyme (Johnson & Johnson, #2258) or another cleaning agent with
approved material compatibility for this medical device
b) Disinfectant: Cidex OPA (Johnson & Johnson, # 20391) or another disinfectant with
approved material compatibility for this medical device
c) Two tanks, one for cleaning and one for disinfection ‐ optional:
1 additional tank for rinsing with deionized/tap water (sufficient size for immersion of
the immersible part of the probe at full length)
d) Soft, fluff free cloth or single use towel
e) Personal protective equipment (gloves, water repellent protective skirt, face protection

Manual Cleaning:
Prepare the detergent solution in a tank with cold water (please follow the instructions of
the detergent manufacturer regarding application, dilution and contact time).
1) The temperature of the detergent solution should be between 15‐30°C, concentration is
1.6%. Please note the minimum contact time of the detergent in the manufacturer's
instruction. If a differing detergent is used, please also note the approved material
compatibility for the medical device.
2) Immerse the immersible part of the probe without connector
into the diluted detergent solution (see Fig. 3). Wipe the
immersible part of the probe under the surface of the detergent
solution with a soft cloth to remove all visible soil. Be sure that
all grooves of the probe are implemented during the cleaning
process.
3) The immersible part of the probe should be left in the
detergent solution according to the specified contact time of
the detergent manufacturer.
4) Wipe the un‐immersible parts of the probe with a soft cloth
dipped with the detergent solution.
5) Rinse the probe with running tap water for 1 minute.
(alternatively: immerse the immersible part of the probe in a
tray filled with deionized water/tap water (see Fig. 3) for 5
min.)
6) Visually check the outer surface of the probe for cleanness. If
necessary, use magnifying glass for visually check. If there is
still soil visible, repeat all above steps.
