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 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.
3. Press and release the MANUAL SET button to move to the next
pair of digits, from seconds to minutes and minutes to hours.
4. After setting the hours value, press and release the MANUAL SET
button to complete the programming procedure. The offset will
become effective immediately.
The local offset may be used in addition to any AUX. OFFSET as
programmed by a MTG-3901, CSD-3901/3902, or CSD-5300 Master
Clock System Driver. All offsets are additive.
Note
The offset value programmed is always ADDED to the current time. To
achieve a -3 hour offset, program an offset value of 21 hours.
