(3) 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 (‡A Program mode table: refer to page 57). The function used to accomplish this is
remote programming.
First, in order to check the current status of the service code parameter, out put the setup list (code: 991) and 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 the next page. Also, before exiting the remote programming
mode, it is advisable to obtain a new list to confirm that only the desired parameters were changed.
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 (except for a digital speakerphone). This frees the customer from the need to remain right next
to the fax while you are making parameter settings. 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.
