and you do the tests shown in the following steps.
The image does not appear in the Monitor
1. Check that the Monitor is switched on (on/off switch).
2. Check that the power supply is correctly connected, and the voltage is 18
Vdc between terminals "+" and "-".
3. Verify that there is no short between "V-" and "V+" in the coaxial cable.
4. Make sure that the Monitor has already been PROGRAMMED (see
page 26).

and the audio panel is set as secondary one (JP1 unplugged).
