CHAPTER 3: Operation
A correctly installed GT1524 virtually runs by itself. Typical operations involve changing volume of an output, muting an input or output, or handling calls on the connected telephone handset. For most installations, a custom remote control (optional) is also used.

Controlling volume
When participating in a conference, you might find it necessary to increase or decrease the volume of a particular output. For instance, when the audio at a distant location is too soft, adjust the output to the speakers so that the level is comfortable.
To adjust the volume
1.Determine which output needs to be adjusted.
2.Scroll to the Outputs menu, select the appropriate output, and scroll to Gain Adjust. Press Enter.
3.Adjust the gain level using the ▲/▼ buttons. You should be able to hear the volume level adjust while increasing or decreasing the gain.
4.Press Enter when you reach the desired volume level.
The volume adjust procedure is the same for all channels.
Muting
To mute and unmute
1.Select the input or output you want to mute and press Enter.
3.Scroll through the parameters until you see Mute. Press Enter.
4.Use the ▲/▼ buttons to select On, then press Enter. The input or output is now muted. To unmute, follow the same procedure, but select Off to deactivate the mute function.
✍
For optimum performance, adjust all inputs to 0dBu before calibrating outputs.
