Setting Clock in '93 Caravan?

Hi-

Without an owners' manual or a stereo system
manual, I'm having trouble finding an online
source that will tell me how to add an hour
to the clock in my '93 Caravan.

???

Thank you.

What kind of radio is it ? Some radios are set by holding down the power button while others have little holes with the letters H and M nearby...

Thank you for the reply.
It occurs to me, there may be no re-setting
the clock; the on/off knob clicks but
doesn't connect to turn the radio on or
off... there are no little holes with H and M
for a paperclip.

Leads me to think that it's one of the
radios where you push in the on/off knob,
which currently isn't happening.

I was hoping for some magic combination
of holding down "set" and another button
or turning the radio knobs-- wouldn't work
if they're not connecting anyway.

Would like to hear if you think of anything
else/if the power has to be on or off
for the clock to be adjusted.

Thank you.

You have two buttons on your radio. "Set" for setting your radio stations and "Sel" or select for switching between the tuner and the clock. To set a radio station, dial up your station of choice, push "set", then push the button you what to program the station to. To set your clock, push "set", then push "sel". You will see the hours displayed. Adjust the tuner knob until you see the correct hour. Hit "sel" again and set the minutes. Then hit "sel" again.

Try that and see what happens. Let me know if you have any problems.
