SerVision Embedded Video Gateway System Guide

Configuring System Settings 25

You can choose from 11 levels of amplification. Level 5 means the volume is not modified at all. Levels 0 through

4 cause the volume to be reduced (the smaller the number, the greater the reduction); levels 6 through 10 cause it to

be amplified (the greater the number, the greater the amplification). Level 6 is generally optimal for the internal

speaker, level 9 for passive microphones, and level 5 for active microphones.

You can test the volume settings as you configure them by connecting to the Video Gateway using a client

application. Volume levels can be adjusted for testing purposes without resetting the Video Gateway unit.

To configure the volume of the internal speaker:

1. Make sure someone is near the Video Gateway to listen to sound being transmitted from the speaker.

2. Using a client application that can transmit audio to a Video Gateway (the MultiClient and the Symbian S60

cell-phone client applications), connect to the Video Gateway.

3. Speak into the microphone of the client device and check with the listener to find out if the volume is

appropriate. If it is not, adjust the settings as described below until they are satisfactory.

4. In the General System Settings screen, under Internal Speaker Volume, select a volume setting.

5. Click Update Now. The volume settings are updated on the Video Gateway immediately

Note: All of the settings on the page are saved when you click Update Now. The volume settings are

implemented immediately, and the changes to the other settings are implemented after the unit is restarted (see

Saving Configuration Changes, page 125). If you modify the volume settings and click the Update button in

the lower-right corner of the screen, the volume settings are not implemented until the unit is restarted.

6. Repeat steps 3–5 as necessary until the optimal volume setting is selected.



To configure the volume of a microphone:

1. Open the client application for which you want to optimize the settings (e.g., the MultiClient), connect to a

live video stream that is linked to the microphone, and listen to the sound. If the volume needs adjustment,

adjust it as explained in the following steps.
