Q. What can be done about wind noise at the customer lane?
A. An External Universal Microphone Assembly (E0957) is available and has worked well in several
locations that were experiencing wind noise problems. It incorporates a combination of foam,
scotchbrite and a large screened opening to break up the wind. It has been found to work the best
when the wind is blowing across the face of the unit rather than directly into the front. A vehicle at
the lane should block most of the direct wind. The assembly mounts to the top of a pneumatic unit.
Q. I have received complaints that customers using the handset on a Hamilton IRT unit can hear other
tellers speaking to other customers. What could cause this?
A. There are multiple things to consider for this issue as follows.
(1) Contact tech support (877-236-0245) with the model and serial number of the matrix to
determine if that matrix needs a modification. Also look for any stickers on the matrix indicating
an upgrade was performed at the repair center.
(2) If the handset board is a model 4012, remove the yellow wire coming from the handset and add a
6.8k resistor in series with the wire.
(3) If the handset board is a model 5012, look for resistor R11 near the terminal strip. If a jumper
wire is installed instead of a resistor either replace the jumper with a 6.8k resistor or add the
resistor in series with the yellow handset wire as in step 2.
(4) Adjust the speaker & mic gain pots on the matrix using the local speaker and microphone in the
IRT, not the handset. Keep the gains as low as possible without the audio being too weak. Since
the IRTs are installed indoors it is not necessary, nor desirable, for the speaker volume to be very
loud.
(5) Lift the handset off the cradle and adjust the gain pots on the 5012 / 4012 board for adequate
volume with the handset. As before, don't set the volumes louder than necessary.
(6) If the tellers sometimes use headsets don't overlook the possibility that the headsets are not
adjusted properly resulting in excessive volume at the IRT.
Q. I am installing a Plantronics CS50 / CS55 wireless headset to an audio console and I can't get it to
work. What could be wrong?
A. One possibility is the phone cable is plugged into the wrong jack on the base unit of the CS50 /
CS55. Be sure to use the jack with the picture of a complete telephone, not the handset jack. It's also
possible that the 5014 wireless interface adapter is being used where it is not needed. Many newer
5001 consoles and all 5501 consoles have a phone jack next to the RJ45 matrix cable jack. With
these consoles the base unit of the wireless headset should plug directly into the console and the
5014 should not be used. Consoles without the phone jack will require the 5014. In this case the pins
from the 5014 may not be making proper contact in the phono jacks of the console. Open up the
console and loosen the 3 screws that hold the console board to the bottom of the chassis. Slide the
board to the rear and tighten the screws. Plug the 5014 in and out of the console several times to help
clean the contacts which may have gotten dirty or corroded over the years. It is also highly
recommended to use the sheet metal screw that is supplied with each 5014 to secure it to the console.
This is especially important with 5001-1 consoles. A slot in the 5014 allows the console ground wire
to attach using the same screw.
