• At the end of the stimulation time, a trigger signal for a nystagmograph is available at the rear 3-pole DIN socket. This
outlet is an electrically isolated photo transistor. The emitter connection which has to be connected to the ground
line of the trigger inlet at the nystagmograph is attached to pin 3. The open-collector connection is located on pin 1
and is to be connected to the positive supply voltage (+5 V or +12 V) by means of a pull-up resistance. The maximum
collector voltage of the transistor may not exceed 80 MA.
3.3.3 Equipotentiality connection
• Connection for potential compensation ( Fig. 2 ► 11 , item D ).
– Connecting cable available from GN Otometrics (see
Accessories and spare parts ► 26
).
3.3.4 Water connection
• Local requirements:
– Waterfaucet with G3/4" external thread.
– Drinking-water!
– Input water pressure: +2000...+6000 hPa.
– Feed temperature: +7...+19.5° C (recommended), but at least 0.5° C below the required lowest cold stimulation
value.
– Drainage fittings (Art.No. 502.0880.0) as to DIN 1988.
• Connection to water supply and waste water:
– Prior to connecting the unit to the water supply, the feed line must be flushed clean by opening the water faucet
for a minute and allowing free flow of the water.
– Connect the filter unit to the water faucet by means of adapter and gasket.
• Insert the gaskets in the cap nuts of the water supply hose.
• Join the nuts with the filter connection and the unit connection ( Fig. 3 ► 12 , item D ).
• Insert the gaskets in the cap nuts of the waste water hose
• Join the nuts with the unit connection ( Fig. 3 ► 12 , item C ) and the drainage fittings.
3.3.5 Connecting the irrigation handle
• Insert a "three-hole gasket" (

).
Important
•
Use only "three-hole gaskets" or the unit will not function correctly!
• Insert a "three-hole gasket" in the irrigation handle and screw it on the free end of the double-barreled hose.
• Open the water faucet.
Check that all connections are tight.
3.4 Start-up
• Insert the handle in its holder; the jet must point to the rear of the unit.
• Switch on the unit (
