What's the difference between scan and scanner of radio?

For hams, the scan is a very common and practical function. With the continuous development of amateur radio, the new word scanner has appeared. So what is the scanner, and what is the difference between scan and scanner?

When we use HD1 to listen to FM radio, many bands only have babble noise. In order to quickly find a channel with a better signal, we can turn on the scan function. In the same way, when there is no information on the channel that our walkie-talkie is listening to, we can also scan to monitor the nearby active channels. Ailunce HD1 supports time (TO), carrier (CO) and search (SO) scan modes.

At present, the scanner function of the walkie-talkie usually means that in the analog mode, the frequency and the CTCSS/DCS are all scanned at the same time and stored, so as to realize the intercommunication of the two walkie-talkies.

The scan function of the walkie-talkie can usually only realize monitor to the scanning frequency, but the scanner can realize the intercommunication of the two walkie-talkies.
