There should be a reset button on either the face of the player or under the faceplate if its removable (tiny black button). Otherwise to remove the cd disconnect the unit and then plug it in or remove the memory fuse or battery lead for 5 seconds.

Press and hold the SOURCE button until the unit turns off. Press and hold the FUNCTION button, until display pops up, then release. (If you do not have a FUNCTION button, then push the AUDIO button) Press the FUNCTION button again until the clock shows on the display. Press the UP and DOWN buttons to adjust the hours. Press the LEFT or RIGHT arrows to move to the minutes. Press the UP and DOWN to adjust minutes. When complete, press the SOURCE button to exit.

Good Luck

I had a similar problem with one of the cursor type keys - I ended up taking the face apart (4 small screws on the back then gently prise apart) & discovered the small pin attached to the back of the button which presses the internal switch had slipped off the pad, it took a couple off attempts to put it back together again but once it was re-assembled it was fine, just be careful not to lose anything! ;)

There are 2 battery supplies to the radio,.

The main one via the ignition key circuit for the radio itself.

The other one is a permanent battery feed to the radio memory.

It is this second (permanent) feed that is missing.

Check the fuse, connectors + wiring to see if there is anything obvious.

If you have a multimeter or test lamp then that can be used to prove the problem

try pressing the reset switch. should be a pencil tip sized hole on either the face or the subpanel. barring that you can try disconnecting power to the radio for a few minutes.

Lookes like you have an older unit but never the less you can usually find wiring diagrams online. ? Do you have an aftermarket harness fitted to your vehicle if not you need to get one for connecting your radio makes it easier. But if you should have a standard wiring for it Your red, yellow, orange, and black the orange would be for a dimmer if you had one and your would also have a blue with which strip which would be your remote wire for an external source which in your case it want be used unlsess your hooking an amp up But Red is you Acc or ignition which will connect to the red on on the harness if you have already purchased one. The yellow is your constant 12v which is for memory and your black of coarse is ground. These wires will all tie into the right harness providing like i said you bought one. If not go get your harness for your vehicle you can pick one up virtually anywhere.
