One of our coaches normally speaks much loader than the rest of the staff.  Is there a way we can turn down just his headset mic?

Yes, with the coaches beltpac or all-in-one headset communicators turned on, hold down the “X” button then briefly press the down volume arrow.  The mic gain will be lowered each time the down arrow is pressed.  Try one press at a time as the coach speaks in his game voice until he’s at a good level.

We’ve noticed that at some away stadiums with enclosed press boxes, the system doesn’t seem to communicate as well. We were told that the system should operate normally through a glass window. Was that incorrect?

No, not all glass windows are the same.  In some instances, a metalized sun screen will have been applied to the window panes which will cut down on the signal that gets through.  If the windows can’t be opened,  line-of-sight operation may be limited. In these situations, one of our standard antenna extension kits should be used to move the antennas out from behind the window so they will be in  direct line-of-sight with the communicators on the sidelines

Just how long can the extension cables be for a remote antenna?

Although HME uses a low loss cable it should be kept as short as possible. Our standard lengths are six feet and 30 feet.  HME cables can be connected end-to-end without using adapters.  Two 30-foot cables (60 feet) would be the maximum recommended length but always test the range prior to the game.

We’ve noticed that more and more of the teams we play are using an HME system.  a) Will they be able to hear our play calls?  b) Will their system interfere with ours?

a)  No, the other team will not be able to hear what is said on your system.  Only registered communicators on your system will have access to your communications.

b)  It’s highly unlikely that the systems would interfere with each other because they’re both changing frequencies around 100 times a second for any one user.  Only in those instances where both systems would happen to land on the same frequency at the same instant would it be noticed.  At those times, a brief clicking may be heard but at no time would communication ever be lost.

Our head coach doesn’t want to hear anything but his coaches coaching. Is there anything that can be done to prevent even the slightest chance of hearing any type of clicks?

Yes, HME systems can be placed into different parts of the spectrum by using HME’s Spectrum Friendly feature.  The two teams would simply coordinate their system operation prior to the game. Following the step-by-step procedure in the Operating Instructions, one team would select the upper part of the spectrum while the other team would select the lower

How easy would it be to expand our current five-coach system to enable more coaches to listen in and even talk if need be?

One DX300 base station will actually allow 19 coaches to take part in the action.  Four coaches can be in the press box using headset splitter cables with up to 15 coaches on the sidelines using wireless communicators.

What type of annual factory maintenance is required and how much is the typical charge to send it in for the maintenance?

We know that some companies have an annual maintenance program but HME does not require our systems to be sent in unless there is a problem. As long as your system is taken care of as recommended in the Operating Instructions, you should have many years of trouble free use

If we ever get into a situation where the system is not operating in the usual manner and we need help, what should we do?

HME mantains a 24/7 Call Center which is there to assist coaches with any unforseen problems just by calling 800-909-6604 toll free

We just received our new system and I noticed some kind of “echo.” During a system check I heard myself everytime I talked.

This is most likely acoustical feedback.  It can happen several ways but it’s easy to correct if you know what to look for. Acoustical feedback can happen in the DX300 in two different ways.  The most common would be when someone takes off their headset with their microphone still on and either sets in down or just holds it at their side. The other would occur when you are talking and it is picked on another coaches headset who is close by. To identify the cause, have everyone else turn off their microphones  while you are talking. The echo should go away. You can have them turn their microphnones back on one at a time until you hear the echo.
