I am trying to remove the CR-915. The FAQs say the later 940 radios (CR-915) have two narrow slots on either side of the faceplate. Look inside these with a flashlight and you will see a flat metal spring. Insert a screwdriver into each slot and lever the spring inwards toward the center of the radio, then pull the chassis out.

I look in and can kind of see the springs. Is there a trick to doing this with one person? I need one hand to lever each spring in and then can't pull out the radio. The springs don't seem to stay in when you lever them in.
