Jensen JCR-255 - Manual (Page 9)

AUTO TIME SET
This unit features an Automatic Time Set system powered by 2 X “AA”
batteries (3V DC) (Included), so you do not need to set the clock time
when first plugged in. After the unit is plugged in, the LED display will
show the current time automatically after you set the time zone and
daylight saving time for desired area.
SETTING THE TIME ZONE
Change to your time zone area by sliding the TIME ZONE switch on
the back of the unit to the appropriate time zone you live in. The default
time zone is set to Eastern Standard Time (EST). Please refer to the
time zone map below when setting the switch position on the back.
1. Eastern Standard Time (EST)
2. Central Standard Time (CST)
3. Mountain Standard Time (MST)
4. Pacific Standard Time (PST)
DAYLIGHT SAVING TIME
Slide the DST (Daylight Saving Time) switch on back of the unit to turn
Daylight saving time on/off. The clock comes with DST in the ON position
as the default. This setting is correct unless you live in Arizona or parts of
Indiana where DST is not observed.
IMPOTANT: Do not change this setting unless you live in an area which
does not observe the Daylight Saving time change.
NOTE: The batteries will become weak after time, so replace the
batteries as needed. To avoid re-program the time and alarm settings,
we recommend leaving the unit plugged in when changing the batteries.
