The TTL Auto Connector Type 3 is designed exclusively for use with the OM-2 (it does not fit the OM-1, OM-1n or OM-2n) to accept a TTL Auto Cord T for off-camera flash operation. The TTL Auto Connector Type 4 is designed exclusively for use with the OM-1n or OM-2n (it does not fit the OM-1 or OM-2) to accept a TTL Auto Cord T for off-camera flash operation.	These units are screwed into the camera hot shoe socket when necessary, in place of the Accessory Shoe, providing full support for TTL "OTF" Flash in combination with a TTL Auto Cord T on the OM-2 or OM-2n. With the OM-1n and OM-2n, the signal for the flash ready / flash OK viewfinder LED is transmitted by TTL Auto Connector Type 4.
