# F-CODE DIALLING

When performing an F-code operation, the F-code (sub-address and passcode) is appended to the fax number that is dialled. Check the F-code (sub-address and passcode) stored in the memory box in the other machine before you perform an F-code transmission. It is convenient to store an F-code (sub-address and passcode) together with the fax number in a one-touch key or group key.
To use the following F-code communication functions, your machine must dial the other machine.

- F-CODE CONFIDENTIAL TRANSMISSION
- F-code polling reception
- F-code relay request transmission

To use the following F-code communication functions, the other machine must dial your machine.

- F-code confidential reception
- F-code polling memory
- F-code relay broadcast transmission

If the destination machine does not have a passcode configured in the F-code, do not enter a passcode when dialling that machine.
Communication using the F-code (sub-address and passcode) is not available when dialling using a speaker or manual transmission.
To store and edit one-touch keys and group keys:
