NB
: The tester supplied with the Saphyr SP processor has a translucent yellow light while the
tester supplied with the Saphyr CX includes a green light.
Earphones
The Saphyr processor is fitted with an earphone socket so that a person without defective hearing
can hear the audio signals entering the processor. This is useful for diagnosing problems with the
microphone (microphone inlet obstructed, faulty microphone).
This test tool is used as follows:
• Turn off the processor
• Gently plug in the earphones to the auxiliary socket marked "AUX" on your processor, making
sure it is connected the right way round
• Switch on the processor to your usual program to check the sound quality perceived
• After use, turn off the processor again before disconnecting the earphones.
NB : There is a risk of the Larsen effect if the earphones are too close to the microphone. The sound
level perceived by a third hearing person using the earphones is not representative of that sensed
by the patient.
