Hi, I have the 7100K Operating Manual.
1. Simultaneously press both the HI/LO LIMITS key and the CAL key to display the date on the CRT screen.
Then the day comes flashing.
2. Press The up and down arrow key to select a new day, then press the ALARM ON/OFF key.
The day is set with the month flashing.
3. Set date and time one by one in the same manner.
When the minute setting is completed, the clock display will disappear.
Now the date and time are set.
At this time,the second is set to 00
