If you press the NO softkey, the Control Display reverts to the format EEPROM menu. If
you press the YES softkey, nonvolatile memory is restored to defaults as previously
described.
4-34. Setting the Internal Clock
An internal clock provides the date (corrected for leap years) and time to the 5790A CPU
(Central Processing Unit). Check the clock setting and set it if necessary.
Note
A long-life lithium battery keeps the clock running during power-off
periods. If the battery in your 5790A should ever need replacement, refer to
the Service Manual. The battery is a button type that is soldered to the CPU
Assembly (A20). Any procedure that involves removing the cover is to be
performed only by qualified service personnel.
To set or change the time and date of the internal clock, proceed as follows:
1.
If you want to set the date or both date and time, set the rear panel CALIBRATION
STORE switch to ENABLE. (See Figure 3-2 for the switch location.) The position of
the CALIBRATION switch does not matter for setting time only.
2. Press [UTIL MENUS] followed by the "Setup" and "Set Internal Clock" softkeys.
The display changes to:

3. You have three choices for the date display format. The active format is identified
under "Date Format" at the right side of the Control Display. Press the "Date Format"
softkey to change the date display format to one of the following choices:
•
M/D/Y, for example, 3/5/91 for March 5, 1991 (leading zeros are not shown but
they are required when you enter a new date).
•
D.M.Y., for example, 5.3.91 for March 5, 1991 (leading zeros are not shown but
they are required when you enter a new date).
•
YMD, for example, 910305 for March 5, 1991 (leading zeros are kept as place
holders). This format is typical for computer program use.
