Canon Fax-L260i User Manual page 105

If you press a one-touch speed dialling button or coded speed dialling code
that has no group (or fax number) registered under it, the LCD displays NO
TEL #. Make sure you pressed the correct one-touch speed dialling button or
entered the correct coded speed dialling code, and that the group you want
has been registered correctly under that button or code.
After entering the first one-touch speed dialling button or coded speed
dialling code, you have five seconds to enter another speed dialling button or
code before the FAX-L260i begins sending automatically. If you have
entered more than one speed dialling button or code, the FAX-L260i waits
for 10 seconds before it begins sending.
3. When you finish entering groups, press START/COPY.
The FAX-L260i then scans the document into memory, and begins dialling
the numbers in the groups.
