 7-8   Solving System Problems

Speaker Problems

 Check the following problems to see the possible cause and
solution.

■  

No sound from the speakers

 Check that the speaker power is on.

■  

Speaker volume is too low

 Adjust the volume control on the speaker. If the volume
is still too low, adjust the volume through the system
software. See “Mixer Module” in Chapter 3.

■  

Sound is only coming from one speaker

 Balance the speaker output by adjusting the balance in
the sound software. See “Mixer Module” in Chapter 3.

Microphone Problems

 Check the following problem to see the possible cause and
solution.

■  

You get no response from the microphone

 Check that the microphone is connected to the
microphone in connector on the back of your system.

 Adjust the microphone (MIC) level through sound
software.

DIAGNOSTIC DISKETTE

 If you are unable to resolve your system's problem using the
Problem/Solutions topics in this chapter, NEC suggests that
you run the diagnostic diskette.

 The diagnostic diskette permits quick testing of all major
system components, individual testing of different system
components, and access to various testing options.
