    I went to the site linked for manuals but T439 doesn't bring up anything. Some others do work. Any help?

To change the color there is a small silver button on the top left. Press it once to rotate the colors press it a second time to lock in the color you like. The large button in the middle (Snooze/Dimmer) with also make changes to the color. Looking at the face of the clock on the top left (radio) and top right (buzzer) are the alarm buttons. Touch once to turn on and once to turn off. Hope this helps. if you need more help.

I had the same problem of the steady red color, but i unplugged the clock, and also took the batteries out and it reset itself.

You can download a 10-page Adobe PDF manual for the Timex T439S Clock Radio here: Just choose the T439 model from the drop-down box and the manual will be available.

There should be a button on the top of the radio. If it's a steady red, then you've got the same problem I have.

My clock light is no shining, the rest of the panel is fine.

you have 2 choices
1; SEE FUSE LAbled, clock
2: if no such label buy and read the factory service manual?
3: or like we do , use a volt meter on all fuses, 1 by one keyon. 12v on both sides is good, (Brainless but 100% effective)! need a video?
have it. with ASE school.
my guess is the clock backlight is dead. right>? backlighting
aka. park/dim lights.l
this can be a bad lamp in the clock, the clock actual fuse is hot all the times.
the backlight lamp is from the dash park dimmer controller.
so if all others dim and 1 dont, that means the actual lamp is bad.
so now you ask one more question. how to change out a lamp.
that is covered in step 2 above, read the manual. or RTM,
I dont post full manuals, yet.
i cant past the whole cluster out , sections here, sorry

if in usa, (not one post ever tells country, and sux big time for helpers)
is USA cars. covers this. read the cluster service sections or where ever your clock resides, (not stated)
as you know, most cars have radio clock, and is a totally differ, answer. to that. (unstated by you) cars world wide have different options for clocks and radios and sometimes 5 or more radios. +++
posting a photo would solve that.?
here is the official toyota book, and again this is USA site!!!

my car has VFD display and if dead, $1000 for new one
so your cheap 10cent lamp is really a blessing, of old school tech.
