1: Introduction
Ray is a small, yet robust, ultrasonic mobility aid designed and produced by
CareTec. Its ultrasonic emissions will recognize objects or obstacles in the way
and inform the user by emitting either acoustic or tactile signals.
How does Ray work? When switched on, Ray constantly emits ultrasonic
waves. Measuring the delay of the reflected waves, Ray is able to determine
the distance of a given object and announce this via acoustic or tactile signals.
The maximum range of coverage depends on the reflective character of the
measured object.
2: Description of the Device
Ray is a slim, handy and light weight device. The case is about 12 cm (5
inches) long with a flat end on one side, and a slightly round end on the
opposite end. On the round end of the device, you can feel 2 small holes, for
inserting the lanyard.
Take the device in one hand, so that the round end faces towards you and the
flat end, with the two sensors faces away from you. On the top surface, you
can feel 2 buttons. In the following instructions, the button further away will be
referred to as “Key 1” and the nearer button as “Key 2”.
On the slim left side you will find an earphone socket. The battery compartment
is located on the base of the device.
Consult instructions before use! Do not operate Ray
without reading the instruction manual. Get acquainted with
the device and all the accessories. Keep the instruction for
reference reading and pass it on with the device.

3: How to Use
Turn the device so that the two keys now face downwards and the round end
faces away from you. Pull the lid of the battery compartment towards you to
open it. The lid is completely removable. Put two 1.5 V AAA batteries in the
compartment with the flat (negative) end of each battery contacting the coil.
Close the lid until it locks in place.
4: Switch the device on and off
Once the batteries have been inserted, Ray is ready for use and automatically
is switched on. To switch it on manually press and hold both keys until you
hear a beep and feel a vibration.
Once Ray is switched on, the following settings are active:
−Recognition Mode : Normal
−Signals : Vibrations
−Trainer Mode : inactive
If Ray does not recognize any objects or obstacles for 1 minute, it will
automatically switch off. To switch it off manually press and hold both keys until
you hear a beep and feel a short vibration.
5: Setting of signals
You can decide whether Ray should give the feedback via acoustic or tactile
signals. To change from vibrations to acoustic signals (and back again), press
key 1.
6: Recognition mode
Ray offers the possibility of two different recognition modes: normal mode and
escape mode. To change from one mode to another (and back again), press
key 2.
6.1: Normal Mode
In normal mode the maximum range of coverage is 2,5 meter (3 yds). Ray will
therefore react to every object or obstacle within this range, either by vibrations
or acoustic signal. The nearer you get to an object, the frequency of vibrations
or signals will increase and vice versa.
5
6.2: Escape Mode
In escape mode the range of distance is reduced to 1,7 meter (2 yds). The
escape mode will help you to identify openings or passageways (e.g. a
doorway in a solid wall). To change to the escape mode, press key 2. Ray will
confirm the change of modes with 2 beep sounds followed by 2 short
vibrations.
If you like to swap to the normal recognition mode again, press key 2. Ray will
confirm the change with 1 beep sound followed by 1 short vibration.
7: Light probe
Ray can also be used as a light probe. A small light sensor is located between
the two ultrasonic sensors. To detect sources of light, press and hold key 2
while swaying the device about the room. Ray will then inform you about the
intensity and proximity of the source of light emitting acoustic or tactile signals.
As soon as you release the key, Ray will go back to the recognition mode.
8: Trainer pupil mode
Ray enables mobility trainers to connect their device to the one of the student,
in order to receive the exact same signals as the student. They will then be
able to support the student with the necessary information and feedback.
The connection between the student’s device and the trainer’s device is only
possible if the student’s device emits tactile signals (vibrations). The student
will need to change his device to the “student mode”. To do this, switch the
device off. Then press and hold both keys and keep both keys pressed, until
you hear the melody of a German folk song followed by one vibration. Release
the keys and your device is now set to the student mode.
The trainer will then need to change his device to the “trainer mode”. To do so,
switch the device on by pressing and holding both keys. Keep both keys
pressed, until you hear the Beethoven melody (which follows the German folk
song) followed by two vibrations. Release the keys and the device is now set to
the trainer mode.
6
Connect both devices via the cable that comes with each trainer unit. Plug both
ends of the cable in the earphone socket of both devices. Both devices are
automatically synchronized and the trainer will now only get the feedback from
the student’s device.
After the training session, disconnect the cable and switch both devices off.
This will automatically end the student and trainer mode.
9: Signal and vibration free mode
Depending on the mode (Normal or Escape Mode), Ray will recognize
obstacles within a range of distance from 1.7 to 2.5 meter. If there are no
obstacles within this diameter, Ray will nevertheless emit short vibrations or
signals. To avoid this constant announcement you can change Ray into the so
called signal and vibration free mode.
To change the device into this mode, proceed as described above (chapter 7.
Trainer mode). To do this, switch the device on and press and hold both keys.
Keep both keys pressed, until you hear the melody of a German folk song
followed by one vibration. Keep both keys pressed until you then hear a
Beethoven jingle followed by two vibrations. Still keep both keys pressed, until
you hear a Star-Wars jingle followed by three vibrations. Release both keys
and you will hear a short beep tone to confirm the new setting.
The device is now set to the signal and vibration free mode, which means that
no vibrations or signals will be emitted if an obstacle is not within the range of
the chosen mode (e.g. 2.5 m for the normal mode, 1.7 m for the escape mode).
Ray will keep this setting even when switched off. When you remove the
batteries the mode will change back to the original mode.
Caution: If you are not sure which mode is set on your
device, just switch it off and on again. If you hear a short
jingle followed by vibrations and a single beep after switching
the device on again, you know, your device is set to the
signal and vibration free mode.
