Manufacturer Listing Context
Hytera lists EHN33 among the optional accessories for PTC760 (EOL). This is a separate host-page listing: the EHN33 accessory title still says PTC70. Confirm the intended radio model and connector before ordering. The PTC760 page also marks the ACN-05 and EHS20 components as end of life; confirm complete-kit availability.
