General Description
The 6-Digital Timer is a camera data optical printer. Dis-
playing and printing of data (Year Month Day/Day Hour:
Minute/OFF/Month Day Year/Day Month Year) can be
selected by mode selection. Date updating is a fully au-
tomatic calendar from the year 1998.1.1 to 2049.12.31.

When digit is set, the MODE key can interrupt the set-
ting mode and change to the next mode.
At calendar mode, no matter what style calendar is
displayed. The sequence of selected digit is always
²Year®Month®Day®Normal² state. The selected
digit will blink at a 2Hz rate.
Real time clock must count at any time even in change
mode or adjusting mode.
IN 3-key application, connect SWK to VSS and SEL.
Press the switch MODE to change the mode as
shown on the chart below, press SEL to select reset-
ting data, press SET key to adjust the selected data.
At time mode, Day is not selected. The sequence of
the selected digit is ²Hour®Minute®Normal² state.
To select digit, press selection key (²SEL² key), ² ²
