Sailor Cu5000

DEVICE: VHF, REMOTE CONTROL UNIT

BRAND: SAILOR

TYPE: CU-5000 REMOTE CONTROL UNIT FOR RT-5022

CU-5000 Remote Control Unit for VHF DSC Radio

Overview

The CU-5000 Remote Control Unit is a semi-intelligent marine control system designed for secondary operating positions, such as bridge wings or auxiliary stations. It allows full VHF functionality and quick muting of incoming DSC alerts from a remote location. Tested for exposure, the unit is highly durable and water-resistant (IP66), making it suitable for demanding marine environments.

System Components

Transceiver
The transceiver includes a high-performance transmitter and a sensitive, selective receiver that reduces interference from nearby VHF or AIS equipment. Its integrated DSC system is easy to operate, while the built-in loudspeaker provides clear, high-quality audio. The unit can be flush-mounted or fitted with a bracket and includes a switch-mode power supply for simplified installation.

Handset
The handset features an ergonomic design for comfortable use, high-quality audio, and IP66 water resistance. The microphone minimizes wind noise, and the speaker covers the ear effectively for clear communication even in noisy environments.
