An emergency transmitter will be considered as capable of developing the power herein specified if the actual power developed is demonstrated by the same method as expressly set forth in (b); Provided, however, That if deemed necessary, this test may be applied to an individual emergency transmitter installed aboard a ship before initial or continued approval thereof. (e) Transmitters not in existence prior to February 1, 1938. Each transmitter which was not in existence prior to February 1, 1938, but which is installed after that date aboard a vessel in order to comply with the rules in this subpart, shall be furnished with a durable nameplate with the month and year of its completion permanently inscribed thereon.

The Commission, in an exceptional case, for a passenger vessel of less than 600 gross tons, may waive those parts of the provisions of § 8.163 relating to the minimum acceptable power of main transmitters, if a satisfactory showing is made that an installation of the specified minimum power is highly impracticable.** [Part 2 (e), as amended Jan. 8, 1938, 3 F.R. 242] 8.165 Record of adjustments. A record shall be kept of the adjustments of the transmitters for the frequencies 375 and 500 kilocycles. The adjustments may be recorded on the transmitters or posted in the radio room.*+ [Part 12 (f)] RECEIVERS 8.171 Main and emergency. Two complete radio receivers shall be provided, one to be associated with the main transmitter and one to be located in close proximity to the emergency transmitter, provided that on a cargo vessel if the emergency transmitter is in close proximity to and operated from the same position as the main receiver, and the main receiver complies with all the requirements for an emergency receiver, the emergency receiver may be omitted.*** [Part 13 (a)] **§§ 8.171 to 8.193, inclusive, issued under the authority contained in sec. 4 (i), 48 Stat. 1068, sec. 356, 50 Stat. 194; 47 U.S.C. 154 (i), 47 U.S.C., Sup., 356. 8.172 Capability of receivers.

In the case of a storage battery emergency power supply, its capability may be determined by a 6-hour discharge test when supplying a load equivalent to 70 percent of the key-locked demand of the emergency radio transmitter and radio station emergency light (s).* [Part 14 (d)] 8.185 Conclusion of tests. At the conclusion of the tests outlined above, no part of the emergency source of power shall have an excessive temperature rise, as defined and measured in accord with standard engineering practice, nor shall the specific gravity or voltage of the storage battery be below the standard for 90 percent discharge for the battery involved.** [Part 14 (e)] 8.186 Circuits to be connected with emergency power. No electrical load circuit (s) other than the emergency radio installation and emergency radio light (s) shall be connected directly or indirectly to the emergency source of power. Emergency batteries, when employed, shall be located in close proximity to the emergency transmitter and receiver, subject, however, to the provisions of § 8.187.*t [Part 14 (f)] 8.187 Location of emergency batteries. Approval of the exact point and method of location, on board a vessel, of a storage battery or engine-driven generator and fuel tank, used as a source of power for any component of a licensed ship radio station, and the method Page 214 *For statutory citation, see note to § 8.171. of ventilating the battery compartment will be within the jurisdiction. of the Bureau of Marine Inspection and Navigation of the Department of Commerce. The approval of the battery or engine-driven generator from the standpoint of its electrical specifications and its ability to produce the required power, will be within the jurisdiction of the Commission.* [Part 14 (g)] 8.188 Availability of emergency power. The emergency source of power shall be maintained in readiness to operate at its full efficiency at all times while the vessel is in active service.* [Part 14 (h)] 8.189 Emergency installation tested daily. Prior to the vessel's departure from each port (but not necessarily more than once each day) and on each day the vessel is at sea, the condition of the emergency power supply and emergency radio installation shall be determined by actual operation.* [Part 14 (i)] 8.190 Daily check of batteries and fuel. If batteries are used as the emergency transmitter power supply, or are used for the purpose of starting a gas or oil driven emergency generator, tests shall be made of the charging circuits for polarity and correct charging rate. Hydrometer readings of the electrolyte of a pilot cell and such other cells as are necessary to determine the state of charge of the emergency battery shall be taken daily. In the case of an oil or gas driven emergency generator, a daily check shall be made of the quantity of fuel in the supply tank.* [Part 14 (j)] 8.191 Entry in radio log of emergency power tests. A statement that the duties required by §§ 8.189, 8.190 have been fulfilled, including a statement of the hydrometer reading and amount of fuel, must be inserted in the ship's radio log each day. During severe weather at sea these duties need not be performed if it is impracticable or dangerous to do so, provided an appropriate entry to this effect is made in the radio station log.* [Part 14 (k)] 8.192 Power leads. The power leads from the main power supply to the main radio installation and from the emergency power supply to the emergency installation shall be encased and routed in the manner best suited to protect them from injury due to damage to the ship and shall be properly protected with fuses. All conductors shall be kept clear of electrical grounds. In the event that, due to the ship's structure, a long indirect routing is necessary, an alternate circuit shall be provided over another route. In all cases, the rules and regulations of the Bureau of Marine Inspection and Navigation of the Department of Commerce relating to the installation of these circuits shall be complied with.* [Part 14 (1)] 8.193 Protection of cooling system. The cooling system of all auxiliary engine units driving the emergency power supply shall be adequately protected or treated to prevent freezing or overheating consistent with the season and route to be traveled by the vessel.*† [Part 14 (m)] AUTO ALARM 8.201 Approved types.
