If this is nor your timer, see all woods timers and manuals:

I have not heard of Woods 16ULD.
Woods timers sometimes have more than 1 model number for same timer, depending on who packaged and sold timer.

You posted under Woods plug-in timer with segments around edge of dial.
If this is not your timer, add a comment.

To program Woods timers with segments:
Rotate dial until current time lines up with arrowhead located on inner dial
Segments around outer edge of dial lift up.
Use fingernail, or small screwdriver to lift up segments when you want timer to turn OFF.
Leave segments down for times you want timer ON.
Slide switch located on top of timer is manual override.
Move switch to ON position when you want lights ON full time.
Move switch other direction for timer program to operate.
Timer dial rotates with passing time.
Program repeats each 24 hours.
Table lamp must be turned ON for timer to function.
If timer doesn't work, check receptacle for power, check that lamp is turned ON, and check that bulb is good.

If plug-in timer does not display, then
1) Reset button has tripped > push reset with paper clip
2) power is off > plug something else in receptacle to check receptacle
3) timer is loose in receptacle > unplug timer, spread prongs a bit, and plug back in
4) timer has gone bad.

Except for a few Woods and Intermatic outdoor timers, plug-in timers have internal rechargeable battery. Battery is not replaceable so when battery goes bad, the timer is bad.

If you buy a timer, save the instructions like gold so you don't have to write fixya next year looking for instruction that nobody can find.

If the timer will not program, then it has gone bad.

Plug timer into wall receptacle
Back-up battery will charge in about 1-2 hours > if battery will not charge, then timer is no good
