Checking the Dial Tone before Sending

The following redirection problem may happen with certain kinds of fax machines
on the market made by companies other than Canon. The Check Dial Tone Before
Sending mode prevents this rare occurrence from happening.
If you are sending a fax document from your machine at the same time another fax
machine (made by a company other than Canon) is trying to send you a fax, your
fax document may end up being redirected to that fax machine, instead of the
original destination you had intended.
Setting Check Dial Tone Before Sending to 'On' enables you to avoid such sending
problems.
IMPORTANT
If the phone line your machine is using is connected to a PBX or network adapter, you
may not be able to send faxes if Check Dial Tone Before Sending mode is set to 'On'.
NOTE
This mode is available only if the optional Super G3 FAX Board or Super G3 Multi-Line
Fax Board is installed.
