10 UDC-5212 and DTD-5225 Digital Time/Date Display Clocks Installation and Operation Manual
Chapter 1: UDC-5212 Universal Digital Clock
Clock Setting Controls
The UDC-5212 Clock may be set using the three push button switches
located on the rear panel. The push buttons, labeled
MANUAL SET ,
CW, and CCW , may be used to program a local time zone offset, or to
manually set the time.
Manual Time Setting
To manually set the clock time, follow these steps:
1. Verify that DIP Switch 2 (the second one up from the bottom) is in
the NORMAL position.
2. Enter Manual Set Mode by pressing the MANUAL SET button
until the seconds LEDs become illuminated and the seconds digits
flash.
3. Use the CW and CCW buttons to set the time. The CW button
increments the displayed value by one, while the CCW button
resets the value to zero.
4. Press and release the MANUAL SET button to move to the next
pair of digits from seconds to minutes and minutes to hours.
5. After setting the desired hours value, press and release the
MANUAL SET button to start the new time.
Manually setting the time in this fashion erases any local offset
previously programmed (See
“Local Offset Programming” ).
Local Offset Programming
A local time offset may be electronically programmed in order to
provide an offset from the input timecode. This is particularly useful for
displaying multiple time zones from the same timecode source.
DIP Switch 3 (the third one up from the bottom) MUST be in the USE
AUX OFFSET position in order to program the local offset. This switch
may be returned to its previous position after programming the offset.
To set a local offset, follow these steps:
1. Enter Manual Set Mode by pressing the
MANUAL SET button
until the seconds LEDs turn off and the seconds digits flash.
2. Use the CW and CCW buttons to set the offset time value. The
CW button increments the displayed value by one, while the CCW
button resets the value to zero.
