Manual for DT620

This is a plug-in timer with internal rechargeable battery.
If battery will not charge, then display doesn't show, and timer is no good.
If this is not your timer, then add a comment with detailed description of timer for more free help.

Also take advantage of fixya phone service.
For a price, fixya expert speaks with you over phone while you work on timer.

Here are generic troubleshooting steps:
If plug-in timer doesn't work
a) Check receptacle for power
b) Check lamp is turned ON
c) Check bulb is good.
d) Mechanical timers: Check tabs or pins are set
e) Check override switch pushed fully in position
f) Try timer in different plug and with different lamp
g) Test circuit with inexpensive circuit analyzer from hardware
h) Don't exceed maximum wattage
i) Programmable: check for overlapping programs
j) Programmable: write out programming steps and double check. Reset timer.
k) Outdoor with photo cell > test with black tape over photo eye
l) Turn photo eye away from light source

Next step would be to identify exact timer, and check steps in manual.

DT121 Manual

All Intermatic manuals
http://www.intermatic.com/customer%20service/instruction%20manuals.aspx

Intermatic does not show DT11
Intermatic shows the DT121 is no longer available

If the display shows and you can set programs, then the battery is good.
Does the manual override work? This indicates whether the timer on-off switch operates.
If manual override does not work, then I discovered that timers are no longer any good

Programming:
Set present time
Then set ON time for program 1
Set OFF time for program 1
Then set ON time for program 2
Set OFF time for program 2
Most timers will not function if there is a conflict in programming > for example Program 1 says ON at 6 and OFF at 7 and Program 2 says opposite or has overlapping times
When events are set, press SET once > this will put timer in RUN mode

If manual override works, and you set programming correctly, but timer does not carry out instructions, I guess the timer is no good.
