Audio

Diagnostic Screen	Description
Speaker Test	Tests the audio cable connections. A 473 Hz audio tone
	indicates that the local audio connections are correct.
	If you run the test from the system during a call, the far site
	will also hear the tone.
	If you run the test from the web interface during a call, the
	people at the site you are testing will hear the tone, but you
	will not.
Audio Meter	Measures the strength of audio signals from
	microphone(s), far-site audio, VCR audio, and any device
	connected to the audio line in.
	•	To check the microphone(s), speak into the
		microphone.
	•	To check far-site audio, ask a participant at the far site
		to speak or call a phone in the far-site room to hear it
		ring.
	•	To check a VCR or DVD, connect it to the VCR inputs
		and play the VCR or DVD to test the audio.
	The Audio Meters indicate peak signal levels. Set signal
	levels so that you see peaks between +3dB and +7dB with
	normal speech and program material. Occasional peaks of
	+12dB to +16dB with loud transient noises are considered
	acceptable. A meter reading of +20dB corresponds to
	0dBFS in the Polycom HDX system audio. A signal at this
	level is likely clipping the audio system.
	Meters function only when the associated input is enabled.

Reset System

Diagnostic Tool	Description
Reset System	Cycles power to the system.
	Note: If Security Mode is enabled, you must enter the
	room password to reset the system.
	When you reset the system using the remote control, the
	system’s user interface allows you to:
	• Keep your system settings (such as system name and
	network configuration) or restore factory settings.
	• Keep or delete the directory stored on the system.
	System reset does not affect the global directory.
	You may wish to download the CDR and CDR archive
	before you reset the system. See Call Detail Report (CDR)
	on page 11-7.
