Notes:
*1 Most fax machines have a button that when depressed, returns dial-tone from the telephone system. This
button is often labeled Hook, Manual Dial, Monitor, On Hook Dial or something to that effect. Find and use this
Hook button on your fax or use the handset. If your fax does not have a handset or a hook button you will need to
temporarily connect a plain old telephone to the TEL jack on the back of the fax machine to change Default Set-
tings.
39 Using a One-Time Transmit Protocol Code
A one-time protocol code allows you use a different protocol (than the default setting) for the current transmis-
sion only. The default protocol setting is not effected or changed. To use a One-Time protocol; get into secure data
mode with the unit you want to send to, take the fax off-hook, dial the desired One-Time Code and press the Start
or Send button. Once your crypto cycles back out of Secure Data mode, the 90si will return to the default settings.
