Setting 5: TEL/FAX REMOTE NUMBER
If you hear a fax tone when you answer a call on a touch-tone extension
phone connected to the same line as the fax, you can make the fax begin
reception by pressing 5, *, and * on the phone. Use this setting if you
want to use a number other than 5 to begin fax reception. You can enter
any number from 0 to 9.
Initial setting: 5

Setting 6: REMOTE RECEPTION SELECT
If you don't intend to use the above TEL/FAX REMOTE NUMBER,
you can turn detection of the number off. This will ensure that the fax
never mistakenly attempts to begin reception if it detects a signal similar
to the TEL/FAX REMOTE NUMBER while you are talking on an
extension phone. Press 1 to turn detection on, or 2 to turn detection off.
