•
consequences due to inaccurate timing, such as sun lamps, sauna, heaters,
crock pots, etc.
NOTICE
Follow local electrical codes during use.
•
Dispose of used batteries promptly per local regulations.
•
1 – Activate the Batteries
The timer comes with two LR44 batteries installed.
Remove the pull tab to connect
1.
the installed batteries.
The display will initialize itself,
2.
then flash “12:00 AM” in the
CLOCK mode (Fig. 1).
NOTE: If display doesn’t light,
the batteries are dead. Replace the
batteries before using the digital
timer.

volatile memory, so it won’t be lost when batteries are removed
NOTE: Replace the batteries as soon as possible after the low
battery indicator appears.

Day Of Week (DOW) Display — events can be programmed for
8.
just one day of the week, all the days of the week, just weekdays
or just weekends
Event Display — the timer can be programmed for up to 28 total
9.
ON/OFF events per week
Mode Display — the timer can display several modes during
10.
setup and programming and three modes during operation:
MANual, AUTO and RANDom. MANual allows for manual operation
of the plugged-in devices, AUTO uses the timer’s exact settings
and RANDom uses the timer’s settings varied by random 5-minute
increments of ±30 minutes.
Output Status Indicator — this is the ON/OFF indicator. When the
11.
green light is on it means that the lamp or appliance should be
on. If it is not on, the bulb may be burned out or the device may
be turned off at the lamp or appliance.
NOTE: You may set up and program the timer before you plug it
in. Be aware that while it is unplugged, the display will turn off to
conserve battery power if there is no pushbutton activity for a few
minutes. If this happens, simply push any button to turn the display
back on.
3 – Clear Any Existing Programming
It’s unlikely that your new digital timer has any existing
programming, but to make sure, use this procedure before setting
the time.
Locate the Reset button. It is the small, round hole adjacent to the
Fig.

Press the Reset button for 3 seconds and release. The display will
3.
light up and then go blank.
Release the ON/OFF button.
4.
NOTE: Pressing the Reset button without holding down the ON/
OFF button will clear the time, but will not clear the non-volatile
(programming) memory.
4 – Set the Time, Date and Location

NOTE: The following procedure must be completed entirely,
including adjustments, in order for the Astronomic and automatic
Daylight Saving Time features to function properly.

7 – Plug In Timer
To conserve battery power, as soon as setup and programming are
complete, plug the desired devices into the timer and plug the timer
into a properly grounded outlet.
About the Batteries
The battery voltage is continuously
•
monitored. If a low voltage is detected,
the low battery indicator will be displayed
(Fig. 15).
The timer requires two LR44 batteries to
•
keep time up to three months without
power.
Replace the batteries as soon as possible after the low battery
•
indicator appears.
Change the batteries within one minute of unplugging in order to
•
keep the time and date settings. Afterwards, if the display is wrong
or flashes “12:00 AM”, reset the time and date. All other settings
(your ON and OFF programming) remain in memory indefinitely
without battery or AC power.
While the batteries are removed, the timer will turn off the display
•
to conserve power.
Dispose of the used batteries promptly according to local
•
regulations. Keep batteries away from children.
