I'd like to know if there is a way to adjust the length of time the GDO light stays on.

I have searched and found the following on this site:
"It can only be done with the premium, 3 function wall switch. The 4.5 minute light timer can be changed to, 1.5, 2.5, or 3.5 minute intervals. Press and hold the Lock Button for about 10 seconds and the green light on the wall switch will flash once. A single blink will indicate the timer is reset to 1.5 minutes. Repeat the procedure and the light will blink twice, indicating it's set for 2.5 minutes. Repeat again for 3.5 minutes etc. etc. etc. up to a maximum of 4 blinks for the factory setting of 4.5 minutes."

These instructions are found on August 5, 2005 at: http://ths.gardenweb.com/forums/load/repair/msg0415415521076.html

I tried theses directions with my control console and they do not work. Further searching I found a manual with these instructions but the instructions applied for the Craftsman Motion Detecting Controle Console as pictured here: http://www.craftsman.com/shc/s/p_10155_12602_00953939000P

Scroll down 1/2 and there is a pdf of the instruction manual and on page 31, the above instructions are similarily listed.

So my question is: is there a way to adjust the length of time with the model I have or is it too old? here is a picture of the control console I have: http://www.searspartsdirect.com/partsdirect/showPart.pd?partNumber=536 87&productGroupId=0009&supplierId=009&pathTaken=partSearch&blt=14
