Select the AM or FM wave band.
Tune the radio to a station then press and hold down the 1 or 2 or 3 pre tune station button until it beeps. Then this radio station is then set to which pre tune button you have selected.
Repeat to set the buttons for other radio stations.

1.Select the radio band and tune in a desired radio station you wish to store in the preset memory.

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

In my experience with aftermarket installs, the unit has to be powered from a source that is always active. Example: the wipers, or blinkers or power windows won't work when the key is off. Your Alpine might be connected to a power source that doesn't send power until the car is on and running. Hence it won't store your radio stations or keep correct time. Check to see how the power for the Alpine is tied into your car.
