Is there any way to adjust the volume of the AXP-340?

I find that even with my headset turned all the way up that the altitude alert coming from the AXP-340 is very quiet.

Go into the maintenance mode by pressing the Function key while turning on power. Then scroll through the settings until you get to Volume. Raise the volume here, it will output a test with each change.

Thanks, didn't think about the maintenance mode...

I'll need to look into this more. The volume was set to 6, I increased it to 10, but the test audio didn't increase much. It was noticeably louder if I turned the intercom off. I have a feeling that my shop set the volume without the intercom on.
