Plan and Prepare for Installation
a. Evaluate the room for optimal placement of the T216 ALS Transmitter.
b. Decide where you want to install your
T216 ALS Transmitter. Use a pencil to
mark the center of the Transmitter’s
location.
c. Using the mounting template provided;
cut a hole in the ceiling with a hole saw.
Items to Remember
* The distance between the T216 ALS Transmitter and the Room Module
should only be a maximum of 50 ft. (15 m).
The T216 ALS Transmitter broadcasts an FM signal. FM signal will travel
* through walls and other visual obstructions. Appropriate attention
needs to be paid to placement of the transmitter for optimal privacy
and performance within the room.
* Do not cut into ceiling without safely checking above the hole location for the presence
of any wires, ducting, or any other obstruction that may exist.
Transmitter Installation
Pull Cable
a. Run the Cat-5e cable from your ListenPoint® Room Module (RM) to
the hole at the desired location for your T216 ALS Transmitter. This
may require additional tools to pull the cable through any
obstructions.
b. Cable should be pulled through the open slot of the mounting platform.
c. Mount the ALS Mounting Platform included with the T216 ALS Transmitter
on the ceiling using the supplied mounting hardware.
* May be attached to an electrical box, or directly to the ceiling or ceiling tile.

Channel Settings
a. The T216 ALS Transmitter has 57 channel settings—19 wide band and 38
narrow band. Adjust the FM receivers to the desired channel.
b. Tune the receivers to the transmission channel.
* We recommend the use of genuine Listen® wireless
receivers and accessories for solid performance and
the highest standards of quality.
Channel Selection
It is important to choose channels that are free from interference to
achieve proper operation of your Listen equipment. This process is trial and
error. Before turning on the transmitter, listen to the wide band channels
(Channels that start with a “2” for 216MHz when using a Listen receiver).
Listen to the audio through the headphone or on a Listen receiver. Choose
a channel with the least amount of interface. Unless you are interfacing
with an existing narrowband transmission system, always use a wide band
channel. If you are using multiple channels follow this process:
a. Same Space. If you are using multiple transmitters in the same space,
the most number of channels that will work simultaneously is three at
216MHz. With all of the transmitters off, listen for interference on all the
wide band channels via the headphone jack on a Listen receiver. Us-
ing the frequency compatibility tables on page 9, eliminate any chan-
nels that have noticeable interference. Now choose the channels with
the widest channel spacing. It is recommended that adjacent chan-
nels be spaced at least 300 kHz. If there is no interference the following
channels are recommended: Channels 2A, 2K and 2V at 216MHz.
b. Distributed Spacing. If you are using transmitters that are spread out
over space, you can achieve more simultaneous broadcast channels.
However, it is critical that your receiver(s) be located as close to its
transmitter as possible. You can use adjacent channels (see frequency
compatibility tables on page 10) in this case as long as the adjacent
channel transmitter is at least 50% further away from the receiver as its
transmitter. Example: The transmitter or the receiver on channel E is 100
feet from the receiver. The adjacent channel transmitter on channel D
should be at least 150 feet away.

Listen SQTM
People are accustomed to listening to low noise, high fidelity audio (deliv-
ered via CD, DVD, etc.). FM radio systems, such as those made by Listen
Technologies, have more inherent noise compared to most sound systems.
To minimize noise, Listen uses a noise reduction technology called Listen-
SQ™. Both the transmitter and receiver must have the SQ feature enabled
to achieve the desired results. SQ is available on your T216 Transmitter and
Listen receivers.
If you are planning to use this product with older Listen systems that do not
have Listen SQ or equipment not manufactured by Listen, you should dis-
able Listen SQ.
Your Listen equipment has been shipped to you with the SQ feature en-
abled. You may need to disable the SQ function for one or more of the
following reasons:
a. You are using your new Listen system with older version Listen
equipment that does not have the SQ function.
b. You are using your new Listen system with equipment supplied by other
manufacturers.
c. You expect that end users may bring and use their own receivers that
don’t have the SQ function..
Phonak® and 3rd Party Hearing Devices
a. Your ListenPoint® T216 Transmitter is able to interface with Phonak
®
hearing devices. Select the Phonak option in the CU control menu
and press enable.
* We recommend the use of genuine Listen® wireless receivers and
accessories for solid performance and the highest standards of quality.
Test Your System
Power Up and Test the System
a. Push the power button on the CU (turning on CU will also power the RM).
b. Test the system with a fully charged microphone – push any button on
the microphone or simply remove from the Charging/Storage Station
to turn on. Wait 10 Seconds, and then adjust the volume on the micro-
phone until you have a comfortable listening level.
c. Set the FM receivers to the appropriate channel.
d. Listen for noise or interference.
RF Maximization Strategies
For proper and dependable operation, Listen receivers should receive a
strong and consistent signal from the originating transmitter. The following
strategies should be used maximize this signal:
a. When using your system, keep in mind that the location of both the
transmitter and receiver is critical to maximizing signal strength.
b. Eliminate or minimize obstructions between the transmitter and the
receivers.
c. Minimize the distance between the transmitter and the receivers.
d. Stay clear of metal objects.
e. Keep the headphone cables connected to the receivers fully
extended. Do not shorten or coil headphone cables. These cables
are the antennas for your portable products.
* If the RF signal to the 216MHz model receivers is too high, the audio will be distorted. This
may happen if you are within 5 feet of the 216MHz transmitter.
Compliance Notice and FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
1. These devices may not cause harmful interference, and
2. These devices must accept any interference received, including
interference that may cause undesirable
Listen’s LPT-T216 Assistive Listening Transmitter (216MHz)
This transmitter is authorized by rule under the Low Power Radio Service (47
C.F.R. Part 95) and must not cause harmful interference to TV reception or
United States Navy SPASUR installations. You do not need an FCC license
to operate this transmitter. This transmitter may only be used to provide:
auditory assistance to persons with disabilities, persons who require lan-
guage translation, or persons in educational settings; health care services
to the ill; law enforcement tracking services under agreement with a law
enforcement agency; or automated maritime telecommunications system
(AMTS) network control communications. Two-way voice communications
and all other types of uses not mentioned above are expressly prohibited.
CAUTION: Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate Listen’s equipment.
FCC Statement
This equipment has been tested and found to comply with the limits for
a class A digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a commercial environment. This
equipment generates, uses and can radiate radio frequency energy and
if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
RF Safety Instructions
For RF Safety and per FCC and Industry Canada regulations, the product
should never be installed within 8-inches (20cm) of typical people loca-
tions.
