(FCC Part15 Subpart C §15.247, 15.253, 15.255)

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio
frequency (RF) Exposure Guidelines. This equipment has very low levels of RF energy that are deemed to comply without testing of
specic absorption ratio (SAR).

(FCC Part15 Subpart C §15.247, 15.253, 15.255)

For Canada

This device complies with Industry Canada licence-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may cause undesired operation of the device.

Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence.
L’exploitation est autorisée aux deux conditions suivantes :

1) l’appareil ne doit pas produire de brouillage;

2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en
compromettre le fonctionnement.

(RSS-Gen §8.4)

The available scientic evidence does not show that any health problems are associated with using low power wireless devices.
There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of
radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health eects (by
heating tissue), exposure of low-level RF that does not produce heating eects causes no known adverse health eects. Many studies
of low-level RF exposures have not found any biological eects. Some studies have suggested that some biological eects might
occur, but such ndings have not been conrmed by additional research. WL-T has been tested and found to comply with IC
radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the IC radio frequency (RF) Exposure rules.

Les connaissances scientiques dont nous disposons n’ont mis en évidence aucun problème de santé associé à l’usage des appareils
sans l à faible puissance. Nous ne sommes cependant pas en mesure de prouver que ces appareils sans l à faible puissance sont
entièrement sans danger. Les appareils sans l à faible puissance émettent une énergie fréquence radioélectrique (RF) très faible
dans le spectre des micro-ondes lorsqu’ils sont utilisés. Alors qu’une dose élevée de RF peut avoir des eets sur la santé (en chauant
les tissus), l’exposition à de faibles RF qui ne produisent pas de chaleur n’a pas de mauvais eets connus sur la santé. De nombreuses
études ont été menées sur les expositions aux RF faibles et n’ont découvert aucun eet biologique. Certaines études ont suggéré
qu’il pouvait y avoir certains eets biologiques, mais ces résultats n’ont pas été conrmés par des recherches supplémentaires. WL-T
a été testé et jugé conforme aux limites d’exposition aux rayonnements IC énoncées pour un environnement non contrôlé et
respecte les règles d’exposition aux fréquences radioélectriques (RF) CNR-102 de l’IC.

Placement

• Depending on the material and
temperature of the surface on which you
place the unit, its rubber feet may discolor
or mar the surface.

Repairs and Data

• Before sending the unit away for repairs, be
sure to make a backup of the data stored
within it; or you may prefer to write down
the needed information. Although we will
do our utmost to preserve the data stored
in your unit when we carry out repairs, in
some cases, such as when the memory
section is physically damaged, restoration
of the stored content may be impossible.
Roland assumes no liability concerning the
restoration of any stored content that has
been lost.

About the transmitter

• Do not use this device closer than 22 cm
(8-11/16 inches) from where a cardiac
pacemaker is implanted. Doing so
may aect the operation of the cardiac
pacemaker.

• The transmitter contains a lithium-ion
battery. If you need to dispose of the
transmitter, do not simply discard it with
your household waste; if the internal
lithium-ion battery becomes unusable, you
should dispose of it in compliance with
local regulations.

• Even if you do not use the transmitter for
an extended period of time, you should
charge it once every three months to
prevent the internal lithium-ion battery
from degrading.

WARNING

Use only the supplied AC adaptor and
the correct voltage

Be sure to use only the AC adaptor
supplied with the unit. Also,
make sure the line voltage at the
installation matches the input
voltage specied on the AC adaptor’s body.
Other AC adaptors may use a dierent
polarity, or be designed for a dierent
voltage, so their use could result in damage,
malfunction, or electric shock.

Additional Precautions

• Any data stored within the unit can be lost
as the result of equipment failure, incorrect
operation, etc. To protect yourself against
the irretrievable loss of data, try to make
a habit of creating regular backups of the
data you’ve stored in the unit.

• Roland assumes no liability concerning the
restoration of any stored content that has
been lost.

• Do not use connection cables that contain
a built-in resistor.
