battery as power source. Very low power consumption. For example, our
model 521 operates for about 500 days on four D-size (LR20) batteries.
we advise battery change once every year. This means very easy maintenance
for users. Model 531 needs a battery change every 2 years.
sound guide system includes a small radio transmitter and receiver. The
transmitter can activate the receiver (called the beacon) when the
partially sighted person needs direction. Receivers are temporary or
permanently fixed close to the object to which the user wants guidance. In
some models the receiver, which is activated by the transmitter, transmits
an adjustable signal or playback of recorded speech. Talking models can be
more functional for children and elderly persons or persons who wants
confirmation of the answering receiver.
Gain is adjustable to
suitable sound level. Some of our models have very high volume and can be
heard from a longer distance.
is adjustable between 300 – 1,200 Hertz. This control is mainly for
visually disabled people who have a hearing defect owing to earlier
harmful noise. The tone is not harmonious so the echoes are not identical
to receiver’s tone.
adjustable .We need given time to take the bearings to a sound source. For
example, one riffle shot does not sound long enough to enable a decision
on the direction to the riffle. The time we need is individual and it is
also dependent on receiver's location. A constant fire alarm signal inside
the room is very hard to locate because the echoes from the signal source
fill the room with sound. Outside it is important that the sounds from
receiver can be heard above background noise. To locate the signal is not
essential in the case of a loud sound, more important are the tone
frequency and characteristics of the tone. In the same way, a bird has
developed its very own tone characteristic at its most audible range.
Pause length or silence between
tones is adjustable, and should be adjusted to the difficulty of the route
is. The general rule is, complicated route - short pause length.
is adjustable and gives preset time how long time receiver is activated.
The receiver has a memory and if it activates again immediately after off
state the next period will be shorter. The receiver assumes that the user
is already almost at the endpoint.
makes enables setting the receiver to the off state by once more pushing
the activate key on the transmitter.
Channel selector is
easily placed on underside, top or inside the receiver, exactly as other
controls. This is of benefit to the user and who loans the aids. The user
can personally select the channel and the loaner doesn’t need to check
the receiver channels, if they are mixed, which easily happens if the
receiver has fixed channels.
is a special receiver which is directly controlled from the transmitter.
This means that the receiver sounds with on-off tune as long as the
activate key is pressed down on the transmitter. This receiver is
primarily constructed to using with other receivers. A mixture of two
sound sources makes determining the actual position uncomplicated.
from Yreca is designed mainly for when one needs both guidance and
information about the target. Inside buildings with many rooms or
especially in unexpected sight difficulties and perhaps if one likes to
receive notification that the correct receiver is activated. Talking
receivers are also excellent aids for activating children, because the
receiver can replay different sounds; talking, singing, bird or animal
sounds. New sounds are very easy to record.
Combination Beacon has both the tone and the speech function. When
the user pushes the activating key the tone signal is turned on and if
user pushes the same key again, the tone signal ends and recorded message
starts. This is an excellent device if one needs both the guidance tone
and spoken information.
is also radio controlled and has rechargeable batteries. This is also our
smallest model of receiver. It is easy to carry and always ready to use if
you want to mark the location of your belongings or want to be sure of
your way back to the starting point when walking outdoors. This one is a
must if one wants to take longer tours in the environment, visit
neighbours or do some other activities where one wants to find something
special. Although this receiver is lightweight, it has about 200 hours
operating time in standby mode before the battery needs re-charging. The
pocket receiver has a built-in automatic battery charger, which means that
the charger automatically goes to the trickle charge state when the
battery is fully charge.
Guide System – Horse riding Beacon is
a fully automatic orientation system with several units. The user starts
the first beacon with a small radio transmitter, and then the system works
automatically. The beacons guide the user with the signals from place to
place. The beacon senses when a horse is passing the beacon. This unit
then starts the next unit and shuts itself down and so forth, so the horse
rider can follow the sound around the whole track. This system is very
practical when partially-sighted persons want to join in different kind of
sport activities, such as horse riding, slalom, a canoeing trip, bicycling,
running, swimming and so on.
