changing the default value. The default T1 timer depends on each country regu-
lation.
• Bit 3: Some old machines can not accept DIS command over 4 bytes, and every time will
become fail. In this case you can set this bit to 1. If this bit is set to 1, JBIG and V8
capability will be disabled automatically.
• Bit 6-7: A fax to be received is canceled and the machine becomes unable to receive it if
the setting of "No. of RINGS" is made longer than the setting of "CNG duration
after dialing." Be sure to make the "No. of RINGS" setting to a value shorter than
the "CNG duration after dialing" setting.
