What does "dial" mean here?

Here, "dial" is part of the phrasal verb "dial in," which means to set or regulate with a dial or keyboard of some kind. The phrasal verb can also mean to call a phone number using a keypad or dial or to access a computer through a phone line. Ex: We dialed in your age, height, and weight to determine your BMI. => BMI means "body mass index." Ex: You can dial into the radio station and request a song.
