13 Great Tips for First Time Matrix Intercom Users 4/1/2012 Tags: Tips & Tricks , Matrix Category: Resources, Tech Blog, Matrix-based Systems Don’t repeatedly push the buttons really fast or run your fingers up and down the control panel keys. Always use a high-quality surge protector/suppressor. Remember that if you have a key latched, then someone on the system can hear what you are saying. Even if you don’t have a key latched to a particular destination, someone may still be able to hear you via a partyline. If you don’t have any keys latched, someone might have a listen key to you and hear your conversations. (In short, if the mic is plugged in and the mic on switch is lit, you can still be heard by others so be careful what you say!) If using a headset, remember to remove it before moving away from a panel. Kill your talk key before taking off and set down your headset otherwise, an unpleasant sound will be produced. Try not to point the microphone towards the loudspeaker. Make sure you know what you are doing before you adjust local panel settings. On the Eclipse-PiCo digital matrix intercom, make sure the Tel-14 is installed above port 17. Recognize what the LEDs on the matrix mean as well as their flashing rate in a normal state of operation so that you can recognize if something goes awry. Familiarize yourself with the reset buttons so you know when and how to use them. Most important of all, read the manual! That will help a great deal!
