BEFORE YOU INSTALL AND OPERATE THE EQUIPMENT
— Prohibitions and precautions —
INSTALLATION
1. DO NOT CONNECT ANY TERMINAL TO AC POWER LINES.
When you mount MY-DA in place of existing bell or chime, be sure to disconnect
wires from the present transformer.
2. DO NOT OPEN THE MY-DA UNIT, WITHOUT FIRST REMOVING PLUG OF
POWER SUPPLY FROM AC OUTLET.
3. Do not drop or hit the MY-DA which may damage the CCD camera unit.
4. Avoid running the connecting wires through doors, windows or between furniture,
which may pinch and disconnect the wires.
5. Install with straight 2-conductor wire. Coaxial cable cannot be used.
WIRING
When surplus wire(s) exists in the cable between video door station and video monitor,
it is possible that the picture quality would be interfered with. In that case, we suggest
connecting a 120 ohm resistor at each end of surplus wire(s).
