The standard setup configures the spectral correlator, select the observing frequency, and leaves the system ready for receiver tuning.

@ PR:check_cali A001 4 5 !* !prepare observing procedure to measure the
! flux of the 5 closest calibrators from the
! IRAM catalogue and the 4 closest ones the JVAS
! Procedure will be executed only if the line
! LET CALIBRATOR_1 "......." is left with dots.
All information appearing on lines marked !**! must have been supplied in the observing proposal, lines marked !* ! will use default values if not specified. The remaining part of the procedure will be defined by IRAM personal (your local contact, usually). The project number (A001 in this example) is assigned by IRAM when observing proposals are received.
After final checking by IRAM staff, this file will be given to the operators, together with a copy of the proposal and any accompanying information the observer may find useful. This small ``dossier'' will be updated by the operator and on-duty astronomer during observations, and a copy of it will be sent to the observer as soon as possible after a configuration has been used for a project (not only at project completion). The original will be kept at IRAM to prepare observations in the following configurations.
