ty“ (Medical Electrical Equipment).
• The device may only be connected to a prop-
erlyinstalledprotectivecontactsocket.
• For mains supply, only use the power cable
supplied (or an equivalent one).
• Pay attention to the ambient conditions spec-
iedinchapter8.0.
• Please pay attention to the period tests in

testingarecarriedoutprofessionally,originalsparepartsareused,andwarrantyclaimsremainuna󰀨ected.
At least every 24 months a repeat test of the electrical safety should be performed according to IEC 62353.
ATMOSrecommendsaninspectionaccordingtothemanufacturer’sspecications.
Scope of test:
• Visual inspection of device and accessories on function-related mechanical defects.
• Checkingthereadabilityofsafety-relatedlabellings.
• Controlling the melt insert of the miniature fuse on the nominal current and the melting characteristics.
• Function control in compliance with the operating instructions.
• Measuring the ground wire resistance
• Measuringtheearthleakagecurrent:NCandSFC
• Measuringthepatientleakagecurrent:TypeBF,NCandSFC
6.3 Sending in the device
• Remove all consumables and dispose of them properly.
• Clean and disinfect the product and accessories in accordance with the operating instructions.
• Place any used accessories with the product.
• Fill in form QD 434 “Delivery complaint / return shipment” and the corresponding Decontaminationcertificate.
This form is enclosed with each delivery and can be found at www.atmosmed.de.
• Thedevicemustbewellpaddedandpackedinsuitablepackaging.
• Place form QD 434 “Delivery complaint / return shipment” and the respective decontaminationcertificate in an enve-
lope.
• A󰀩xtheenvelopetotheoutsideofthepackage.
• Send the product to ATMOS or your dealer.
6.2 Period tests
MedicaldevicesliketheATMOSStrobo21LEDmustbefail-safeatalltimes.Donotusethedeviceifitisobviouslydamaged.
Prior to each use a function check has to be performed:
• Checkwhetherthedeviceoritscablesarevisiblydamaged.Damagedcableshavetobereplacedimmediately.
• Connect the microphone and sing a tone. The device has to show a constant frequency. As soon as you change the pitch
level, the frequency changes.
• Checkwhetherthefootcontrollerworksasdescribedinchapter4.2.3.

Indication is illegible Insu󰀩cientcontrast Adjust contrast by pressing the ‚up‘ and ‚down‘
button (see chapter 4.1.1).
Blurred image For technical reasons the vocal
fold oscillations / vocal fold po-
sition are blurred if there is an
increase in brightness during
stroboscopy with the LED light
source, (see chapter 4.2.2 Res-
olution / brightness control).
Reduce the brightness of the LED light source.
Foot controller is positioned at
„heel“, thereby the signal for
permanent light is generated.
Changetofreezeimagemoderespectivelyslow
