Federal Communication Commission Interference Statement

(For ISA570 and ISA570W)

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 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.

(For ISA550 and ISA550W)

This equipment has been tested and found to comply with the limits for a Class B digital

device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed and

used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and receiver.

•Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

•Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: Any changes or modifications not expressly approved by the party responsible

for compliance could void the user's authority to operate this equipment.

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.

IMPORTANT NOTE:

FCC Radiation Exposure Statement: (For ISA550W and ISA570W)

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with minimum distance 20cm

between the radiator & your body.

This transmitter must not be co-located or operating in conjunction with any other antenna or

transmitter.

The availability of some specific channels and/or operational frequency bands are country

dependent and are firmware programmed at the factory to match the intended destination.

The firmware setting is not accessible by the end user.

Industry Canada statement:

This device complies with RSS-210 of the Industry Canada 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.

Ce dispositif est conforme à la norme CNR-210 d'Industrie Canada applicable aux appareils

radio exempts de licence. Son fonctionnement est sujet aux deux conditions suivantes: (1) le

dispositif ne doit pas produire de brouillage préjudiciable, et (2) ce dispositif doit accepter

tout brouillage reçu, y compris un brouillage susceptible de provoquer un fonctionnement

indésirable.

IMPORTANT NOTE:

Canada Radiation Exposure Statement: (For ISA550W and ISA570W)

This equipment complies with Canada radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with minimum distance 20 cm

between the radiator and your body.

NOTE IMPORTANTE: (Pour l'utilisation de dispositifs mobiles)

Déclaration d'exposition aux radiations:

Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un

environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de

20 cm de distance entre la source de rayonnement et votre corps.

This device has been designed to operate with an antenna having a maximum gain of 1.8 dBi.

Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The

required antenna impedance is 50 ohms.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna

of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To

reduce potential radio interference to other users, the antenna type and its gain should be so

chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that

necessary for successful communication.

(Le manuel d'utilisation de dispositifs émetteurs équipés d'antennes amovibles doit contenir

les informations suivantes dans un endroit bien en vue:)

Ce dispositif a été conçu pour fonctionner avec une antenne ayant un gain maximal de 1.8

dBi. Une antenne à gain plus élevé est strictement interdite par les règlements d'Industrie

Canada. L'impédance d'antenne requise est de 50 ohms.

Conformément à la réglementation d'Industrie Canada, le présent émetteur radio

peutfonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé

pourl'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage

radioélectriqueà l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain

de sorte que lapuissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité

nécessaire àl'établissement d'une communication satisfaisante.

UL/CB

Rack Mount Instructions - The following or similar rack-mount instructions are included with

the installation instructions:

A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the

operating ambient temperature of the rack environment may be greater than room ambient.

Therefore, consideration should be given to installing the equipment in an environment

compatible with the maximum ambient temperature (Tma) 40 degree C specified by the

manufacturer.

B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount

of air flow required for safe operation of the equipment is not compromised.

C) Mechanical Loading - Mounting of the equipment in the rack should be such that a

hazardous condition is not achieved due to uneven mechanical loading.

D) Circuit Overloading - Consideration should be given to the connection of the equipment to

the supply circuit and the effect that overloading of the circuits might have on overcurrent

protection and supply wiring. Appropriate consideration of equipment nameplate ratings

should be used when addressing this concern.
