Note:
• Selector 1 is applicable only to models equipped with flat-bed scanners.
• Selectors 3 and 4 are applicable only to models supporting pseudo-ringing of a
connected external telephone.
• Selectors 3 and 4: Delay of FAX line disconnection when switching to the pseudo-
ringing external telephone
When the machine receives a phone call, it can make the connected external telephone
ring (so called pseudo-ringing). During pseudo-ringing, if you pick up the handset of the
external telephone, the line might be disconnected due to cut-off of the line current. To hold
the line, the machine may supply line current by making use of the pulse generator circuit
that forms a parallel loop. This way the FAX line disconnection may be delayed. These
selectors determine the delay period.
