When your audiometer will not calibrate with your Oscar, but sound is coming out of the earphone, there are several checks which might prove useful.  Turn your Oscar on and tap on the cover.  The response light should be visible every time you tap.  If it does not light, replace the battery or batteries with new alkaline batteries.  The Oscar IV and Oscar V use a 9v battery.  Earlier Oscar II and Oscar III models use 6 AA batteries. Check the power switch on the Oscar IV and Oscar V and be sure that it is in the ON position. For earlier Oscars, the headset must be placed on the Oscar to turn the power on (there is a small button on the earphone coupler with is actually the power switch).

When installing the new batteries, unscrew the knurled knob on the side of the Oscar and lift the cover. Remove the old 9v battery and replace it with a new battery.  Be sure the replacement battery is new. If you are using an Oscar II or Oscar III, remove two batteries at a time and note their position.  The first two batteries will be in one direction, the middle two batteries will be in the opposite direction, and the final two batteries will be in the same direction as the first set.

If, after replacing the battery (batteries) and turning on the power, the Oscar response still does not light when you tap on the cover, your Oscar will have to be returned for service.  Lipin/Dietz Associates can provide a free loaner Oscar should you need to send it to us for service.

If, after replacing the battery  (batteries)  the Oscar does respond, but your audiometer is still not responding, you will need to check the connections to the sound booth and audiometer. Click here for further help.
