12.4. Remote Programming
If, after the call is connected, the customer describes the situation and it is determined that the problem can be corrected by
making parameter changes, this function makes it possible to change parameters such as the user code and service code from
another fax (using DTMF tones). Therefore, travel to the customer's location is not required. However, it is not possible to
change all the parameters remotely (Program Mode Table (P.104)). The function used to accomplish this is remote program-
ming.
making parameter changes, this function makes it possible to change parameters such as the user code and service code from
another fax (using DTMF tones). Therefore, travel to the customer's location is not required. However, it is not possible to
change all the parameters remotely (Program Mode Table (P.104)). The function used to accomplish this is remote program-
ming.
First, in order to check the current status of the service code parameter, print out the setup list (code: 991) and the service list
(code: 999) from the customer's fax machine.
Based on this, the parameters for the desired codes can be changed.
The procedure for changing and listing parameters is described on Entering the Remote Programming Mode and Changing
Service Codes (P.103). Also, before exiting the remote programming mode, it is advisable to obtain a new list to confirm that
the changes were made correctly.

Hint:
Since the connected telephone is in use during the remote programming mode, it may be helpful to ask the customer to switch
to the speakerphone. This frees the customer from the need to remain right next to the fax while you are making parameter set-
tings. When finished, inform the customer. Also note that in very noisy locations where the DTMF tones are not audible, the
remote programming function will not work.
