Overview

Unser Mobilfunk-Störsender neutralisiert effektiv drahtlose Schummeltools wie Mobiltelefone, WLAN, Bluetooth und Smartwatches. Er spielt eine wichtige Rolle bei der Wahrung der Sicherheit und Integrität bei vertraulichen Besprechungen und standardisierten Prüfungen.

Der Störsender ist ein omnidirektionaler Vollband-Kommunikationssignalunterbrecher, der zur siebten Generation von grünen Signalstörern gehört. Er verfügt über ein Gehäuse aus Aluminiumlegierung und zeichnet sich durch eine schnelle Wärmeableitung aus. Das militärtaugliche Anti-Fall- und Anti-Kollisions-Design bietet eine leistungsstarke Leistung.

Es vereint die Vorteile tragbarer und stationärer Störsender und zeichnet sich durch einfache Tragbarkeit und hohe Störleistung aus. Die Gesamtleistung von 120 W kann Signalbedrohungen im Störbereich schnell und effektiv beseitigen. Es blockiert jedoch nur den Empfang von Mobilfunkstörgeräten vor Ort und beeinträchtigt umliegende Basisstationen überhaupt nicht.

Vorsichtsmaßnahmen:

1. Zu den Faktoren, die den tatsächlichen Abschirmungsbereich beeinflussen, gehören Signalfeldstärke, Entfernung zur Basisstation, Mobiltelefonformat, Hindernisse, Installationshöhe, Installationsspezifikationen usw.
2. Es ist normal, dass sich der Host nach längerem Betrieb erwärmt. Wenn die Temperatur zu hoch ist, schalten Sie bitte den Strom aus und wenden Sie sich an Ihren Händler vor Ort.
3. Die normale Installationshöhe beträgt 1,8 m bis 2,5 m. Versuchen Sie, einen Ort zu wählen, an dem sich zwischen dem Zielabschirmungsbereich kein Hindernis befindet.
