This diagnostic command is used for calibration and setup. When the projector is in READY mode and has been given the
command to cue cine forward, this command checks the gain value for VR1 on the CPU/Main Logic card and displays it
in the rightmost two digits of the corresponding numeric displays on the operator control consoles. The projector must be
in READY mode; if the projector is in NOT READY mode, this command will release the upper torque motor brake (see
