User

manuals

for

transmitters

equipped

with

detachable antennas shall also contain the following

notice in a conspicuous location:

Immediately

following

the

above

notice,

the

manufacturer shall provide a list of all antenna types

approved for use with the transmitter, indicating the

maximum permissible antenna gain (in dBi) and

required impedance for each.

6.2.2

APPROVED EXTERNAL ANTENNA

TYPES

Transmitter Antenna (from Section 7.1.2 RSS-Gen,

Issue 3, December 2010):

The RN2903 module can only be sold or operated with

antennas with which it was approved. Transmitter may

be approved with multiple antenna types. An antenna

type comprises antennas having similar in-band and

out-of-band radiation patterns. Testing shall be

performed using the highest gain antenna of each

combination of transmitter and antenna type for which

approval is being sought, with the transmitter output

power set at the maximum level. Any antenna of the

same type having equal or lesser gain as an antenna

that had been successfully tested with the transmitter,

will also be considered approved with the transmitter,

and may be used and marketed with the transmitter.

When a measurement at the antenna connector is

used to determine RF output power, the effective gain

of the device's antenna shall be stated, based on

measurement

data

from

the

antenna

manufacturer. For transmitters of output power greater

than 10 milliwatts, the total antenna gain shall be added

to the measured RF output power to demonstrate

compliance to the specified radiated power limits.

Testing of the RN2903 module was performed with the

antenna types listed in Table 5-1 Tested External

Antenna Types.

Australia

RN2903 module RF transmitter test reports can be

used in part to demonstrate compliance in accordance

with ACMA Radio communications "Short Range

Devices" Standard 2004 (The Short Range Devices

standard calls up the AS/NZS 4268:2008 industry

standard). The MRF89XAM9A module test reports can

be used as part of the product certification and

compliance folder. For more information on the RF

transmitter test reports, contact Microchip Technology

Australia office.

AS/NZS 4268:2008 refers to the USA FCC 15.247 RF

standards, the frequency limits of 915 - 928 MHz apply

in Australia.

To meet overall Australian end product compliance, the

integrator must construct a compliance folder

containing all relevant compliance test reports e.g. RF,

EMC, electrical safety and DoC (Declaration of

Conformity) etc. It is the responsibility of the integrator

to know what is required in the compliance folder for

ACMA compliance. For more information on Australia

compliance, refer to the Australian Communications

and Media Authority web site http://www.acma.gov.au/.

The Australian Communications and Media Authority:

This radio transmitter (identify the device by certifica-

tion number, or model number if Category II) has been

approved by Industry Canada to operate with the

antenna types listed below with the maximum permis-

sible gain and required antenna impedance for each

antenna type indicated. Antenna types not included in

this list, having a gain greater than the maximum gain

indicated for that type, are strictly prohibited for use

with this device.

Conformément à la réglementation d'Industrie Can-

ada, le présent émetteur radio peut fonctionner avec

une antenne d'un type et d'un gain maximal (ou

inférieur) approuvé pour l'émetteur par Industrie Can-

ada. Dans le but de réduire les risques de brouillage

radioélectrique à l'intention des autres utilisateurs, il

faut choisir le type d'antenne et son gain de sorte que

la puissance isotrope rayonnée équivalente (p.i.r.e.)

ne dépasse pas l'intensité nécessaire à l'établisse-

ment d'une communication satisfaisante.
