ICAO Doc 9432
11.1 SELECTIVE CALLING (SELCAL)

11.1.1 SELCAL is a system by which voice calling is replaced by the transmission of coded tones on the frequency in use. Receipt of the assigned SELCAL code activates a calling system in the cockpit, and the need for a continuous listening watch by the pilot is obviated. Detailed SELCAL procedures may be found in Annex 10, Volume II.

11.1.3 Any necessary SELCAL check shall be initiated by using the phrase “REQUEST SELCAL CHECK”. Subsequent receipt of the SELCAL code tone should be acknowledged by the phrase “SELCAL OK”.

11.1.4 In case the coded signal is weak or unable to activate the cockpit call system, the pilot should advise the controller by using the phrase “NEGATIVE SELCAL, TRY AGAIN”.
