I think it is labeled "Chan. Ind." as in Channel Indicator. Google AI spit out this in response to my guess:
 

In the context of the Turkish Air Force F-4E 2020 Terminator cockpit, "CHAN. IND." is an abbreviation for Channel Indicator.

• Function: It is part of the upgraded avionics suite, often linked to the radio or electronic warfare systems (such as the EL/L-8222 ECM pod) operated by the backseater (Weapon Systems Officer) to show the current active frequency channel or Electronic Counter Measures (ECM) channel.
• Upgrade Context: Following the Israeli-led modernization (Terminator 2020 project), the cockpit was overhauled with new digital displays and modern mission systems, retaining some analog switch labeling.
• Usage: It is commonly used in Turkish Air Force F-4E 2020 jets flying in modernized, 111 Filo (Eskişehir) 111th squadron training operations

Google changed it mind and spit out this:

"Chan. Ind." on Turkish F-4 Phantom (specifically F-4E 2020 Terminator) instrument panels refers to the Channel Indicator for the UHF radio or navigation system, likely associated with the 18-channel preset system of the ARC-150 UHF radio or the updated MFX-484 UHF/VHF system installed during modernization.

• Context: It is part of the UHF/COMM or AUX radio control panels, enabling the pilot or Weapon Systems Officer (WSO) to see which pre-programmed frequency channel (1-18 or 1-20) is currently selected.
• Function: In the Turkish F-4E/2020 Terminator (modernized by IAI and Aselsan), this indicator works with the updated CDU-900 (Control Display Unit) to show selected comms channels.

It could all be AI slop, but I can't find any better references.
