5.3.1 Local Time Operation / Setting
When power is applied to the MD93, the system defaults to local time mode (there is no indication
or annunciation showing “LOCAL” time). To set time and preferences (e.g. 12/24 hour, display or
hide seconds) refer to Figure 7. Note: As minutes and seconds can also be set in universal time
mode, it is not necessary to set minutes or seconds when setting local time (refer to universal
time operation/setting). However, if minutes and/or seconds are set for local time, the system will
update the minutes and seconds in universal time as well.
