Every time you disconnect a battery cable you have to reprogram the radio stations ( if that's what you are asking )
Hold clock button and volume increase or decrease to index hours of minutes.
You could try recharging the battery, or having the connections checked by a mechanic.
The room fuse powers the internal lights and radio and also the terrible beeping sound when the door is ajar.
There is a code to type in to re-activate your radio. The code is sometimes on the lid of the fusebox located in the engine compartment. You may also find it inside your manual.
There is nothing to reprogram except the radio presets and the clock.

Anytime a battery cable is disconnected you have to reprogram the set radio stations
Assuming you are talking about the car's computer, you shouldn't have to reprogram anything besides your radio station presets and your clock.
