univox CTC-120 Cross The Counter Loop System

Introduction

CTC Cross-The-Counter systems are complete systems for equipping reception desks and counters with an induction loop. The system consists of a loop driver, a loop pad, a microphone and a wall holder. Installed in a reception desk or counter, the system gives hearing hearing aids users the possibility to communicate with the staff behind the desk with greatly enhanced speech perception.

The system is always activated and no special preparations have to be undertaken, neither by the hearing impaired nor by the staff. The only requirement for the hearing aids user is to put their hearing aids in T-position and for the staff to speak normally into the microphone.

All Univox® drivers have a very high output current capability resulting in powerful and secure products fulfilling existing standards, IEC 60118-4.

Thank you for having chosen a Univox® product.

Installation guide for CTC-120

with microphone for glass or wall

Installation and commissioning

Choose a suitable place for the loop driver. Consider that the loop pad, the microphone and the loop driver’s power supply will be connected to the driver. If needed, attach the wall holder facing upwards on the selected spot.
Choose a suitable location for the microphone. It can be placed on a wall or on glass. When choosing a place for the microphone, consider that the staff shall be able to stand or sit and talk in a normal, relaxed way with the listener. An example of how the system can be laid out, see fig. 1. Place the microphone cable under the desk in such a way that it will reach to where the loop driver/wall holder is mounted. The microphone cable is 1.8 meters.
Mount the loop pad under the reception desk. The loop pad should be attached in the angle between the front and the upper part of the reception desk as shown in fig.1 and 2. This will ensure a constant field distribution with the right direction and also allow hearing aid users to tilt their head forwards, for example when writing. When mounting the pad (be careful not to damage the loop cables inside the pad), place the loop pad cable in such a way that it will reach the loop driver/wall holder. The loop pad cable is 10 meters.

Placing the loop pad in the highest position possible ensures a stronger magnetic field and thus gives better speech perception for hearing aid users

Connect the cables power supply, loop pad and microphone, see page 5. If the wall holder is being used, run the cables from the loop driver’s power supply, loop pad and microphone through the wall holder from underneath. Place the driver in such a way that the connector side is facing down and you can read the text on the front of the driver in the right direction. Connect all three cables, see page 5. Finally, lower the driver into the wall holder and connect the power supply to mains.
When all connections are completed correctly the LED-indicator for mains power on the right hand side of the front of the driver shall light up. The system is now ready to be used.
The loop current is adjusted by turning the volume control at the front of the driver. Verify the loop level/volume with a Univox® Listener. Bass and treble controls shall only be adjusted in exceptional cases

with gooseneck microphone

The system is always activated and no special preparations have to be undertaken, neither by the hearing impaired nor by the staff. The only requirement for hard of hearing people is to put their hearing aids in T-position and for the staff to speak normally into the microphone.

Installation and commissioning

Choose a suitable place for the loop driver. Consider that the loop pad, the microphone and the loop driver’s power supply shall be connected to the driver. If needed, attach the wall holder facing upwards on the selected spot.
Choose a suitable place for the microphone. It can be placed on a desk or a table.

An example of how the system can be laid out, see Pic. 3. Place the microphone cable under the desk in such a way that it will reach the place where the loop driver/wall holder is mounted. The microphone cable is 1.5 meters.
Mount the loop pad under the reception desk. The loop pad should be attached in the angle between the front and the upper part of the reception desk as shown in fig. 3 and 4. This will ensure a constant field distribution with the right direction and also allow

hearing aid users to tilt their head forwards, for example when writing. When mounting the pad (be careful not to damage the loop cables inside the pad), place the loop pad cable in such a way that it will reach the loop driver/wall holder. The loop pad cable is 10 meters.

Connect the cables power supply, loop pad and microphone, see page 5.

The loop current is adjusted by turning the volume control at the front of the driver. Verify the loop level/volume with a Univox® Listener. Bass and treble controls shall only be adjusted in exceptional cases.

Troubleshooting

Verify the control LEDs following the instructions in this installation guide. Use Univox® Listener to check the sound quality and basic level of the loop. If the loop driver does not perform satisfactory, check the following:

Does the mains power indicator light? If not, make sure that the transformer is correctly connected to the power outlet and to the driver.
Is the loop current indicator lit? This is a guarantee that the system works. If not, check that the loop pad is not broken and correctly connected, and make sure to check all other connections.
Attention! If headphones are connected the loop current indicator is disabled.
The loop current indicator lights but there is no sound in the hearing aid/headphones: check that the M-T-O switch of the hearing aid is in T or MT mode. Also check the status of your hearing aid batteries.
Bad sound quality? Adjust the loop current, bass and treble controls. Bass and treble adjustment should normally not be needed.

Make sure that Listener is turned on (red LED flashes). If not, change the batteries. Please make sure that the batteries are inserted correctly. If the loop receiver sound is weak, make sure that Listener is hanging/hold in vertical position. Adjust volume if necessary. Weak signal might indicate that the loop system doesn’t comply with the international standard IEC 60118-4.

Should the system not work after having made the product test as described above, please contact your local distributor for further instructions.
