The ZM-10 wireless anchor alarm repeater from Yuan Zhou Electronics extends anchor alarm signals on ships without wiring.
The ZM-10 wireless anchor alarm repeater is designed to forward anchor‑alarm signals from an electronic chartplotter to distant crew areas such as the captain’s or chief mate’s cabins. It uses a wireless link, eliminating the need for additional cabling, and supports up to ten receivers with identity‑code filtering for reliable, ship‑only operation.
The manual explains how to connect the chartplotter power and alarm interfaces, install the BNC antenna, and operate both the transmitter and receiver units. It also covers testing, registration, and resetting procedures, as well as troubleshooting tips for antenna adjustment and signal reliability. This manual is written in Chinese.

Press the red alarm button and the silver cancel button; these two keys are used for regular product testing as well as alarm activation.
The repeater powers off automatically because it draws power from the chartplotter’s supply.
Long‑press the “Initialize” button for 4 seconds; this clears the stored transmitter ID and requires re‑registration.
