4.5.1 Thermal process for reducing bacterial
count
Purpose:
Reductionofbacteriacountinthewarmwatercircuitto
prevent or clear a contaminated system.
Activation:
Occurseachtimetheunitisswitchedon.
• Condition for starting the correct thermal process for
reducing bacterial count:
- The irrigation handle must be inserted in the holder
ontheside(jetpointingtoreversesideoftheunit).
ª Ifnot,awarningsignalisgiven(warningalsosounds
whenthehandleisremovedduringthethermal
cleaningprocedure).
ª Additionally,theerrorcode"F0"isshown(disappears
whenhandleisreturned).
) In the thermal process for reducing bacterial count hot
waterisbeingductedthroughtheirrigationhandle.
Please do not take the handle from its holder or spray
water!
) Metalpartsoftheirrigationhandleandofthedouble-
barrelledhosewillbehot!Pleasedonottouchmetal
parts during the thermal cleaning procedure!
• Duringthethermalprocessforreducingbacterialcount,
thetemperaturedisplayshowsa'd'ontherstsegment
andtheremainingtime(inminutes)onthesecond
segment.
• Aftercoolingdownto37°Ctheunitwillautomatically
switchintoirrigationmode.
4.5.2 Irrigation mode
Purpose:
Rinsing of the auditory canal.
Properties:
• Temperature:37°C,permanentlyset.
• Positionoftheadjustinglever:High(seeg.6,page13).
Activation:
• Automatically after completion of thermal cleaning
procedure and taking out the handle or by key (,g.1).
• When the irrigation mode is not used (handle remains
inholder)theVariothermpluschangesintotheenergy
saving mode after 5 min.
• Reactivation of the irrigation mode by taking the handle
out of the holder or activating a key on the temperature
control unit.
• Ifthe37°Cpushbuttonisrepeatedlypressed,theheating
isswitchedoff.
ª Waterwithfeedtemperatureisavailable.
4.5.3 Stimulation mode
Purpose:
Stimulation of the vestibular organ.
Properties:
• Temperature: corresponds to the preselected cold or
warmstimulationlevel
• Positionoftheadjustinglever:Low(seeg.6,page13).
• Duration: as pre-set by the timer.
Activation:
• Initially select the type of stimulation by actuating either
warm-stimulationorcold-stimulationkey(,,g.1)
(seesection4.1forpre-settingoftemperature)
ª Waterwithpre-settemperaturevalueowstohandle.
• Wait for 20 seconds.
• Operatethe"timer-start-key".
• Preparation for stimulation:
- Operateunit15secondsinholdingposition,sothat
the jet can be positioned correctly in the auditory
canal.
) Duringthisperiod,thewaterisdirected,viathehandle,
into the drain in order to guarantee an optimum
temperaturestability;withanopticalindicationbythe
ashinggureintemperaturedisplay.
Do not start stimulation by operating the release lever at
the handle until you hear the audible signal!
• Carrying out the thermo-stimulation by actuating release
lever at handle (,g.4).
• At the end of the stimulation period a control signal for a
recording unit is issued at the nystagmograph output.
• After completion of the stimulation the unit remains in a
holding position for 15 seconds so that the handle may
be removed from the auditory canal.
ª Duringthistime,waterowsintothedrain;againan
opticalindicationismadebyashingtemperature
value.
• Repeatedactuationofthe"timer-start-key"leadsto
stopping timer operation.
• Second actuation of the currently active key effects
deactivation of the pertaining stage.
ª Heatingisswitchedoffcompletely.
ª Stimulationwithcoldwater(feedtemperature).
4.5.4 Energy saving mode
Purpose:
Reduction of energy consumption.
Activation:
• Actuationofkey"heatingon/off”(,g.1).
ª Heatingisswitchedoff.
• Afterveminutesofnon-useoftheunit.
