General Information
The starting and ending dates for Daylight Saving Time must be set each year. Both the starting and ending dates must be set for automatic Daylight Saving Time adjustments to be operational.
To place the clock in the program mode, slide the program switch located on back of clock from Run to Prgm. This now activates the six manual card-positioning switches (IN1, OUT1, etc.) on top of the clock to function as program switches:
| Switch | Function |
| IN1 | + (Increase set value by 1) |
| OUT1 | – (Decrease set value by 1) |
| IN2 | ENTER (Register / save the set value) |
| OUT2 | BACK (Return to previous setting) |
| IN3 | CLEAR (Cancel the set value) |
| OUT3 | MODE (Select mode / function group) |
