condition (3)>
Use it to set RTN signal transmission conditions. Raise these parameters for more lenient
conditions if errors occur frequently at time of reception because of transmission of the
RTN signal.
Memo:
Any of the following error codes may be indicated at time of reception because of RTN
signal transmission
##104, ##107, ##114, ##201
RTN signal transmission condition (1) affects the ratio of error lines to the total number of
lines per single page of received images.
RTN signal transmission condition (2) affects the standard value (*2) of burst errors (*1).
RTN signal condition (3) affects the number of errors not reaching the standard value of
burst errors.
*1: transmission error occurring cover several lines.
*2: for instance, if '15' is set, a single burst error will represent an error occurring
continuously cover 15 lines.
If any of these lines is detected while an image signal is being received, the RTN signal will
be transmitted after receiving the protocol signal of the transmitting party. Higher
parameters restrict the transmission of the RTN signal.
