Solution: Check the Pop Server IP Address. Contact the network Administrator

Regarding the beeping noises. The DX-800 has multiple settings for beeps, rings and the dialing monitor. If it is the latter, press MONITOR button once, then press the DOWN arrow, until silenced. Some ringer/beep settings are under Fax Parameters, some are in a special SERVICE MODE.

let us know if you can isolate which one and we can help turn it off. At least now you know what the 720 code means.

Good Luck!

press the monitor button and check for a dial tone thats the first step. have you had any changes to phone system or internet recently. you could also prees the memory button and try to send a fax directly without memory use, you should hear it dial then connect and send.

there might be an incomlete file waiting to be sent again in which case the last document will go into a que and be delayed. (maybe) you can retry the docoment again by pressing the memory button and sending directly, press the monitor buttonfirst and listen for dial tone, the send

I looked in the manual, you can hit the monitor button and then hit the left arrow, this will reduce the volume. When you get to the desired level, hit the monitor button again.
