Equipment intended for fixed installations shall have an 50 RF socket. Port
39、able equipment shall be of small size and light in weight. Portable equipment shall include provision for the connection of external microphone and headset. Portable equipment shall have a colour which distinguishes it from the portable VHF equipment specified in ETSI EN 300 225 1. The equipment sha
40、ll be operational within 5 seconds of switching on. Fixed installation equipment shall be so installed that access for inspection or maintenance shall be available. 4.2 Controls The number of controls shall be the minimum necessary for simple operation. The equipment shall be provided with an on-off
41、 switch and a visual indication that the equipment is switched on. The equipment shall be provided with a manual volume control by which the audio output may be varied. ETSI ETSI EN 301 688 V1.2.1 (2016-03) 8 The press-to-transmit switch shall be non-locking and return to standby (receive) mode when
42、 released. The time necessary to change from transmission to reception, or vice versa, shall not exceed 0,3 seconds. The equipment shall have a channel selector and shall clearly indicate which frequency the equipment is set to. The channel switching arrangement shall be such that the time necessary
43、 to change from one frequency to the other does not exceed 5 seconds. It shall not be possible to transmit during channel switching operations. Independent selection of transmitting and receiving frequencies shall not be possible. In the transmission mode, the output of the receiver shall be muted.
44、4.3 Operating frequencies The equipment shall be capable of operating on the single frequency channels 121,5 MHz and 123,1 MHz only (aeronautical emergency frequencies), with manual control (simplex). The equipment shall operate with class of emission A3E. 4.4 Labelling The labels on the equipment s
45、hall be permanently fixed to the exterior of the equipment. All controls and indicators shall be clearly labelled. The labelling shall at least comprise the following information: - text containing the words: “Only for emergency communications with aircraft“; - brief operating instructions; - type d
46、esignation of the equipment and serial number; - expiry date for any primary batteries; - compass safe distance, according to ISO 25862 2. 4.5 Power source For portable equipment, the source of energy shall be a primary battery that may be replaceable by the user without the use of special tools and
47、 without degrading the performance of the equipment. In addition, provisions may be made to operate the equipment using an external source of electrical energy. Fixed radio installation should be powered from the ships main source of electrical energy. In addition, it should be possible to operate t
48、he installation from an alternative source of electrical energy. Alternatively, the source of energy may be a primary battery integrated in the equipment and may be replaceable by the user. Primary batteries shall have a shelf life of at least 2 years. Provisions shall be made for protecting the equ
49、ipment from damage due to accidental reversal of the polarity of the battery or of any external power supply.
