Auto-Set Time and Date Settings
This model is equipped with the Auto-Set feature, meaning that the time and date have been programmed at the factory
and will already be set when you first plug the model in. Auto-Set will automatically adjust the time and date settings for
daylight-saving time and leap years. Auto-Set is programmed for Eastern Standard Time; if you do not live in this time zone,
you can easily switch the setting to one of six other time zones.
1. To change your time zone setting, press and hold the 8 Time Zone Button. The current Auto-Set Time Zone in the
lower-right-hand corner of the display will flash for approximately ten seconds, after which the display will revert to the
standard clock display.
2. While the Auto-Set Time Zone is flashing, press the 1 Reverse and 6 Forward Buttons to select your time zone.
The display will show each zone's current time setting. There are seven zones to choose from:
Auto-Set Time Zones
Z-01 Atlantic Standard Time
Z-02 Eastern Standard Time
Z-03 Central Standard Time
Z-04 Mountain Standard Time
Z-05 Pacific Standard Time
Z-06 Alaskan Standard Time
Z-07 Hawaiian Standard Time
3. Find your time zone, then press the 4 Enter Button or wait about ten seconds for the clock to beep twice and the
setting to lock into place.
