Too Loud The dialtone and every sound the fax makes is WAY too loud. Is there a way to turn the volume down or off?

Press user tools/counter then select facsimile then general setting should look for sound and adjusted there will be about 4 different sound settings adjust as needed

check if there is some kind of magnetic interference near speakers.

There is a setting to adjust the fax volume. Press the User Tools button on the operation panel, and then on the touch screen press either Fax Features or Fax Settings, and then under the first tab (I think it's General Settings) there should be an option for volume adjustment. You can either turn the volume down or you can turn it all the way off.

Main Menu 1. General Setup
1. Mode Timer
2. Paper Type
3. Paper Size
4. Volume
1. Ring
2. Beeper

Turn the volume down.
Check your gain.
That should solve it.

1- incoming volume press the down arrow till you want the desired level

2-outgoing volume. press monitor you will hear a dial tone. press down arrow till desired level and press monitor again your done

for faxing out. press monitor-left silver arrow a couple time to turn the volume down. then press monitor again.

then for incoming, press the left silver arrow by it self and it will turn the ringer down

There are 4 volume controls to access them press MENU.

You should see “MACHINE SETTING?” if not use the SET arrows to scroll through the different menus, stop when you see “MACHINE SETTING?” Now press the SET button.

Now use the up & down arrows to get to
Buzzer Volume = that the machine beeps
SET
Key volume = the tone that sounds when you press keys on the control pad
SET
Alarm volume = the alarm if something happens.
SET
Line volume = sets the level you hear at the fax is actively transferring a fax.

If you want to change any of the settings, press the up or down arrows to the level you like best and press SET if you don’t what to change that item just press SET. When you have adjusted all levels the way you want them press STOP and the levels will be remembered.

The most annoying sound to most people in the Line Volume. I have known people that like it as quiet as posable in thier work, but the problem is if you turn down the ALARM you won’t know when there is a problem. Many people like a little line volume so that they hear when they dial into a busy phone line, or if someone picks up the shared voice line.
