Table of contents
Quick guide from the manual
The Aiphone MY-DC/A and MY-DG/A are PanTilt door stations designed for use with the MY Series Video Entry Security system. They feature 2-wire audio, video, and PanTilt control. Key operational requirements include using non-polarized parallel cable and ensuring the camera is protected from direct sunlight or strong light sources to maintain image quality.
Wiring
The system uses a 2-wire connection. Do not use coaxial cable or two separate wires. If replacing an existing doorbell, ensure the old transformer is removed. For extended distances up to 300m, the MYW-BA adaptor is required. Always terminate extra pairs in the cable at both the door station and the monitor ends to prevent image interference.
Mounting
Semi-flush mounting: Unlock the front cover using the tool provided. Attach the mounting bracket to a 3-gang box. Secure the unit to the bracket with two screws and replace the front cover.
Surface-mounting (MY-DC/A only): Mount the MYW-R box to the wall or a single-gang box. Attach the door station to the box using two screws.
Operations
The red LED indicates the call button location. Pressing the button activates the chime and video on the indoor monitor. The system supports hands-free communication. In low-light conditions (down to 1 Lux), the infrared illumination allows for visibility within 50cm of the camera.
Technical Precautions
The units are weather-resistant but should be protected from direct rain or overhead cover is recommended. Operating temperature range is -10°C to 60°C. If condensation occurs inside the lens due to temperature changes, it will evaporate naturally. Clean the unit only with a soft cloth and neutral household cleanser; avoid abrasive materials.

Practical help
Common problems
This is caused by condensation; it will clear naturally as the unit warms up and ventilation occurs.
Ensure the camera is not facing strong light sources like direct sunlight or street lights. Use the monitor's backlight button to compensate.
Ensure all extra wire pairs in the cable are terminated at both the door station and monitor ends.
Before use
- Verify the use of 2-conductor parallel cable (do not use coaxial).
- Remove any existing doorbell transformers if replacing an old system.
- Ensure a 120 ohm resistor is installed if using extra wires.
- Check that the mounting location is protected from direct rain.
- Confirm the monitor unit is compatible with the MY Series.
