I just bought a house with the Night Sentry EJ351 timer. There was no instruction manual with it so I do not know how to set the timer. It is hard wired in the garage and set to operate outside lighting. I am looking for help to set the timer for the lights to come on at dusk and go off at dawn.

Here are the instructions: http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/ej351c%20-%20english.ashx
You will have to pick the times you want the lights to go on and off.

Here is a reply in plain english, from the manufacturer's manual on their website of discontinued, (obsolete) equipment. The link can be found here as long as they keep it alive.

rapid Programming.
1. Move control lever to OFFCLEAR for at least 5 seconds
• red indicator light goes off
• all time settings are
erased.
2. Move control lever to ON.
• red indicator light will start
flashing.
3. Check a clock; then turn pushbutton time dial clockwise at least one click.
• stop at the half hour nearest to present time (note
AM or PM).
Note: When turning pushbutton time dial, do NOT
accidentally PRESS at the same time.
4. Press pushbutton time dial once to enter present time.

8. Press pushbutton time dial to enter OFF time.
• controlled light(s) turn off.
9. Repeat 5-8 for other on/off times.
10.Turn pushbutton time dial for at least 2 more turns
from the first ON time to complete this program
• red indicator light will turn on and stay on (steady
light means timer is in automatic).
Note: Pushbutton time dial does not turn
automatically after setting to indicate time of day

Turn it to off (clear) for 20 seconds, then turn it on. make sure the light is blinking. turn it to the right time (turn atleast 1 time) and push it, the light is going to go off, that sets your time at that time, the light will stop blinking. then turn till what time you want it to go on, and push again the light will go on. then push till the time you want it off and push, the light will go off. for about 6-8 times. and then turn it till the light go's on that means your timer is on and working
