Its shows time, but in different modes it shows various times. In this picture i believe is Aircraft Time Over Waypoint (HH.MM.SS), because its in a-g master mode.
When XMIT is in Position 1 we have Radar Priority. When in Radar Priority and the jammer is transmitting and ownship radar and HARM/HTS performance is reduced by 40%. - > this called SPJ or self protect jamming.
To activate SPJ, set CMDS to semi (or auto, not recommended) and press cms aft short. CMS aft will set the system from standby to active and will automatically transmit when you are locked by a radar. Pressing cms forward will launch the selected cmds profile. The system will go back to standby mode, each time a radar had been jammed, and you have to give consent to the jammer to standby mode.
When XMIT is in Position 2 we have ECM Priority. When in ECM Priority, the FCR and HARM/HTS are silenced unless an AIM-120 is the active weapon. In this case, it behaves the same as Position 1. - > same as Position 1.
Position 3 is an active jamming. Set CMDS to man mode and press cms aft to turn on or cms right turn off. When activated it will turn off the radar "NO RAD" on the hud.
amber S - standby mode CMS right
green A - active mode CMS aft
blue T - transmitting
A-G > HUD soi > ICP 7 > TMS up long > designate area of interest > press 0, this make it the active SPI
From here you can switch to ccrp and use the tgp look for targets.
