FCC Statements (cont.)
The device must be professionally installed The intended use is generally not for the general public. It is generally for industry/commercial
use.The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter that is not normally
required. the user has no access to the connector. Installation must be controlled. Installation requires special training This module has been
assessed against the following FCC rule parts: CFR 47 FCC Part 15 C (15.247, DTS and DSS) and CFR 47 FCC Part 15 E (NII). It is
applicable to the modular transmitter。
This radio transmitter FCC ID:VPYLB2DU has been approved by Federal Communications Commission to operate with the antenna types
listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the
maximum gain indicated for any type listed are strictly prohibited for use with this device.
The concrete contents to check are the following three points.
1) Must use antenna such PCB antenna (with gain not exceeding +0.1dBi at 2.4GHz & -0.4dBi at 5GHz) ;
2) Should be installed so that the end user cannot modify the antenna;
3) Feed line should be designed in 50ohm
Fine tuning of return loss etc. can be performed using a matching network.
L'émetteur radio FCC id: VPYLB2DU a été approuvé par la FCC
Utilisez les types d'antennes énumérés ci - dessous et indiquez le gain maximal admissible. Le gain du type d'antenne non inclus dans cette
liste est supérieur au gain maximal de l'un des types énumérés et ne doit pas être utilisé avec cet équipement.
Le contenu spécifique de l'inspection comprend les trois points suivants.
1) Une antenne dont le gain ne dépasse pas +0.1dBi (2.4GHz) and -0.4dBi (5GHz)
2) Doit être installé là où l'utilisateur final ne peut pas modifier l'antenne;
3) La ligne d'alimentation doit être conçue pour 50 ohms
Le réseau correspondant peut être utilisé pour affiner la perte de retour, etc.
