A:AnswerIt can be used as either a freezer or refrigerator. I use it only as a freezer since that’s what I needed. The capacity is great also; just the right size.
A:AnswerIf the unit is having trouble maintaining a cold temperature, you will get an alert.
The LED on control panel turns on and a beep sounds. If the temperature returns
to a normal range, the alert turns off. You can also press any button to turn it off.
A:AnswerPress and hold Lock for three seconds, then + or - on the control panel to set the temperature. I found the user guide here:

We bought ours as an emergency replacement while waiting on warranty repairs on our fancy Four Door Fridge/Freezer and this little guy has been working well so far. I wish, however we has purchased the larger model, but we just needed to get what was immediately available. We love that it can be changed from a Refrigerator to a Freezer and back at will.
Hope this helps!
