Hong Kong MRCC is also equipped with a system called Digital Selective Calling (DSC) system to receive distress signals generated from ship's DSC.

To communicate with ships, Hong Kong MRCC is equipped with high-powered radio transceiver, telex, marine VHF and Inmarsat telephone and facsimile. All these equipment are aimed to communicate effectively with ships in an urgent situation.

To augment its extensive communications capability, Hong Kong MRCC is also equipped with a large number of direct lines or "hotline" telephones to agencies that can support SAR operations. For example, hotlines go to control rooms of Marine Police, the Air Traffic Control at Chek Lap Kok, Government Flying Service and Fire Services Department.
