Summary Main Characteristics Notes - Related Units
The Recordata Back 4 replaces the standard back to imprint the date, the time, a counter or a code directly on the film. Mounted on the OM body, this unit is capable of imprinting a wide choice of dates and codes for imprinting on the film according to your requirements.
The data available are:
1) Year, month, day (the Japanese order);
2) Month, day, year (the American order);
3) Day, month, year (the European order);
4) Hours and minutes;
5) Counter;
6) Identification code up to six digits.
If no imprinting is required, switch off the back and the unit will function as an ordinary back.
It can be left on the camera as a standard back permanently, and also be used as a highly accurate calender watch.
Simple pushbutton operation allows correction or change in the coded data  as desired.
Data can be imprinted on any film (color film between ASA 25~1000 and B&W film of ASA 80 or above).
Only single-digit OM bodies have exchangeable backs.
To remove, open the back by pulling the Rewind Knob/Camera Back Release, and press down the Hinge Release Pin at the left hand side.
Two 1.5V silver oxide batteries or alkaline-manganese batteries or equivalent should be used. Silver oxide batteries will last for about two years, alkaline-manganese batteries for about six months.
A special semi-hard case is optionally available to contain an OM body with attached Recordata Back 4.
The OM-1 and OM-2 (without the 'n' designation) cannot be used with the Recordata Back 4; for these bodies Recordata Back 3 is recommended.
The OM-1n, OM-2n, OM-2Sp, OM-3(Ti) and OM-4(Ti) use the built-in Direct Contact Pin to synchronize data imprinting which eliminates the need for a Recordata cord.
The maximum year that can be imprinted by Recordata Back 4 is 2009.
