How do i set time on DCX3400

Hi Mary
To set the timezone:

• In the Normal Time Display, press the [MODE] button to enter the Alarm Time Mode.
• Press the [SET] button to set the desired time zone. Refer to the Time Zone map on the display, P=Pacific, M=Mountain, C=Central and E=Eastern.
• Press the [MODE] to return to the time mode position.

Full instructions for all of the clock features can be found at the following link:

Hi, Please follow the link from Motorola site DCX3400 Manual
Please don't rate until follow-up questions have been answered.

Select The Time Zone - For Sentry Self-setting Atomic Clock (ATC - 10)
The default time zone is Pacific zone.
1. In the normal time mode, press the MODE key to enter the alarm time mode.
2. Press the SET key to change the time zone.
each press of the SET key will move the time zone back one hour
P= Pacific M=Mountain C=Central E=Eastern
3. Press MODE key when correct Time Zone is highlighted.

I think the Instructions may tell you to use the ADJUST key instead of the SET key.
ADJUST key does not work for TIME ZONE change, SET key works.
This will set your clock to your chosen Time Zone for normal time.
Instructions for the ATC20 are located at the following url

I couldn't find a manual for your Timex, but here are the setting instructions:

Clear the timer by pushing hour and minute at same time. To set current time, hold time button down and push hour. Then hold time button down and push minute.
To set the time for light to turn on, hold the ON button down and push hour until it gets to the hour you want it on (same for Minute). To set time for light to go off, hold the OFF button down while you set the hour and minute.

Press and hold the set button. The digits will start flashing. Use the H.Adj and L.adj keys to set the digits. Use the Set button to advance until all entries are as you want and then press Set to finalize the time. Hope this helps.

If you are still wondering about this, pull the knob out to the first click. turn one way to set day, turn the other way to set date. Pull out further to set time.

Moderately difficult, but not impossible. ;) I picked up this clock @ second hand store with no instructions and was able to figure it out how to set it in about 15 minutes. I liked the calendar feature on the face and the LCD (as opposed to LED because I prefer my bedroom dark when I sleep).
When setting this clock, one of the keys is to pay attention to the the icons displayed on the face toward the lower left. Default "MODE" is time set. To set the time: Press "SET" followed by either "HOUR" or "MIN" while the display is flashing to increment the hours and the minutes to the correct time. As previously state, the default "MODE" is time set.
Pressing "MODE" one time accesses a secondary clock that you might use if you regularly travel to another time zone (new icon w/ 2 clocks appears). Setting the secondary clock uses the same method above.
Pressing "MODE" a second time accesses the first alarm setting (alarm clock icon starts flashing). Same method to set.
Pressing "MODE" a third time accesses the secondary alarm setting (second alarm clock icon appears and begins flashing). Same method to set.
Pressing "MODE" a fourth time accesses a timer (hourglass icon appears). Same method to set.
Pressing "MODE" a fifth time allows you to set the calendar (calendar year appears where the digital clock display was). Press "SET" to change the date: "HOUR" increments the month; "MIN" increments the day; "MODE" increments the year. Press "SET" again to exit.
Pressing "MODE" a sixth time returns to the default time set mode.
I hope this helps someone! God's blessings in Jesus Christ! ~Thomas
