This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
This device contains license-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development
Canada’s license-exempt RSS(s). Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference, including interference that may cause undesired operation of the device.
L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR d’Innovation, Sciences et
Développement économique 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’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre
le fonctionnement.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
Les changements ou les modifications qui n’ont pas été expressément approuvés par la partie responsable de la conformité
peuvent faire perdre à l’utilisateur son droit d’utiliser l’appareil.
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 interference when the equipment is operated
in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed

The carrier shall be modulated using a 50 % duty cycle square wave signal.
c)
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent
actual modulation, it would be worst case.
