Polling Polling Security Polling Security allows you to prevent unauthorized polling of your machine. When this function is activated, polling will only take place when one of the following conditions is met: ♦ The fax number of the polling fax machine has been stored in your machine's list of permitted fax numbers (called "passcode numbers"). The polling fax machine must also have its fax number programmed in itself, as explained in Entering Your Name and Fax Number in Chapter 1. ♦ A System number has been programmed in the polling fax machine which matches your machine's System number or one of your machine's ID numbers. ♦ An ID number has been programmed in the polling fax machine which matches your machine's System number. System and ID numbers are 4-digit numbers which provide you with an alternate means of giving and receiving polling permission when you don't want to use fax numbers. The steps for programming these numbers are described in the following pages. Note: System and ID numbers can only be used if the other fax machine is also a Sharp machine. Turning Polling Security on and off Polling Security is turned on or off with Option Setting 8 as explained on page 203. 166
