H-400-4856 Wireless PTT Switch To: FCC Part 15.231 2. Equipment Under Test (EUT) The following information (with the exception of the Date of Receipt) has been supplied by the customer: 2.1. Identification Of Equipment Under Test (EUT) Brand Name: Wireless PTT Switch Model Name or Number: H-400-4856 Unique Type Identification: H400485601 Serial Number: 000528901 FCC ID Number: RMJPRR0002 Country of Manufacture: UK Date of Receipt: 22 March 2004 2.2. Description Of EUT The equipment under test is a wireless PTT switch operating at 433.92 MHz that forms part of a Personal Radio System which includes a separate 2.4 GHz transceiver and switch pack. Although the switch pack (which is attached to the 2.4 GHz transceiver) has a PTT switch, this is not easily accessible when the transceiver is worn in a pouch. The wireless PTT switch, which is normally strapped to the user’s weapon, allows remote operation of the 2.4 GHz transceiver (without the user having to remove his hands from the weapon). 2.3. Modifications Incorporated In EUT During the course of testing the EUT was not modified.
