29、97 1 Scope This ETS lays down the minimum requirements for VHF radio transmitters and receivers operating on board ships in frequency bands allocated to the maritime mobile service, used on inland waterways as defined by Regional Agreements or responsible Administrations. This ETS applies to VHF tra
30、nsmitters and receivers fitted with a 50 Cl external antenna socket or connector for use on board ships on inland waterways and operating in the bands between 156 and 174 MHz allocated to the maritime mobile service by the Radio Regulations l, appendices 18 and 19. For countries where the Automatic
31、Transmitter Identification System (ATIS) is mandatory, the requirements of annex B apply. 2 Normative references This ETS incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are
32、 listed hereafter. For dated references, subsequent references to or revisions of any of these publications apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. Il ITU Radio Regulations (1990 Revise

39、 be suitable for use on board ships. All controls shall be of sufficient size to enable the usual control functions to be easily performed and the number of controls should be the minimum necessary for simple and satisfactory operation. For the purpose of conformance testing, relevant technical docu
40、mentation shall be supplied with the equipment, The VHF maritime mobile service uses both single-frequency and two-frequency channels. For two-frequency channels the Radio Regulations require a separation of 4,6 MHz between the transmitting frequency and the receiving frequency. The equipment shall
41、be capable of operating on single frequency and two-frequency channels with manual control (simplex). It may also be capable of operating on twofrequency channels without manual control (duplex). No scanning or multiple watch facilities shall be implemented. The equipment shall be able to operate on
42、 all channels defined in the Radio Regulations l, appendix 18. Operation on channels 75 and 76 shall be prevented by appropriate means. The equipment shall be so designed that use of channel 70 for purposes other than Digital Selective Calling (DSC) is prevented. The Administration may grant permiss
43、ion for one or more channels in addition to those as defined by the Radio Regulations l, appendix 18. The possibility to apply automatic power reduction to any of these channels shall be available. It shall not be possible for the user to change the programmed settings of these channels. The output
44、power shall be automatically limited to a value between 0,5 and 1 W on the following channels: - 6,8, 10, 11, 12, 13, 14, 15, 17,71,72,74and77. It shall not be possible to transmit while any frequency synthesizer used within the transmitter is out of lock. It shall not be possible to transmit during
45、 channel switching operations. 4.2 Controls and indicators The equipment shall have a channel selector and shall indicate the designator, as shown in the Radio Regulations l, appendix 18, of the channel at which the installation is set. The channel designator shall be legible irrespective of the ext
46、ernal lighting conditions. Where an input panel on the equipment for entering the digits O - 9 is provided, this shall conform to ITU-T Recommendation E.161 2. - Page 11 ETS 300 698: March 1997 STD-ETSI ETS 300 bS8-ENGL 1797 M 3q00855 OLb72q8 217 W The equipment shall have the following additional c
47、ontrols and indicators: - an on/off switch for the entire installation with a visual indication that the installation is in operation; - a manual non-locking push to talk switch to operate the transmitter; - a manual switch for reducing the transmitter output power to a value between 0,5 and 1 W; -
48、an audio frequency power volume control not affecting the audio level of the handset; - a squelch control; - a control for reducing the brightness of the equipment illumination to zero; - an output power detector giving a visual indication that the carrier is being produced. The equipment shall also
49、 meet the following requirements: - the user shall not have access to any control which, if wrongly set, might impair the technical characteristics of the equipment; - if the accessible controls are located on a separate console and if there are two or more control consoles, one of the consoles shall have priority over the others. If there are two or more control consoles, the operation of one console shall be indicated on the other consoles. 4.3 Handset and loudspeaker The equipment shall be fitted with an integral
