[. . . ] With proper care and maintenance your ACR product will last for years. It is important that you thoroughly read this product support manual to understand the proper care and use of your ACR product. ACR is proud to be certified to ISO 9001: 2000, the International Standard for Quality. The following battery types are suggested for use in ACR Marker lights: Suggested Screw Terminal batteries: BRAND ANSI/NEDA: Duracell: Rayovac: Eveready: MODEL NUMBER 915, 915C, 915D, 915AC M915, PC915 942, 945 510S Suggested spring terminal batteries (for use with optional battery adapter 9434): BRAND ANSI/NEDA: Duracell: Eveready: Energizer: Rayovac: Panasonic: MODEL NUMBER 908, 908C, 908D, 908AC M908, PC908 509, 1209 EN529, (not 529) 941, 944 W-4FD NOTE: Check adapter to ensure that screws are tight during regular maintenance. SECTION 1 - INSTALLATION 1. 1 Installation Procedure The installation procedure requires that the mounting bracket be securely fastened in any convenient location that would provide immediate access in the event of an emergency. Suitable length ¼ - 20 stainless screws should be used for mounting the bracket. 1. 2 Battery Installation The SM-2 is normally shipped from the factory without a battery. Follow disassembly instructions in Section 2 of this manual for battery installation. The SM-2 uses a standard 6 volt lantern type battery with screw terminals. SECTION 2 - MAINTENANCE 2. 1 Operation The unit should be tested monthly. The unit should begin flashing, at a rate of about one flash per second. 2. 2 Inspection Check the exterior of the unit for damage which might affect proper operation (damage to globe, cracks in case, etc. ). D 2. 3 Disassembly This will ordinarily be required only if testing shows that the light is malfunctioning, or if battery replacement is required. Depress the top cap of the unit, by pushing straight down on the top cap assembly, until the swivel locks may be turned outward, clear of the cap. Grip the light lens (using a clean cloth or gloves for a better grip on the smooth surface and to avoid marring the lens surface) and pull upwards until the top cap is clear of the case. Turn the unit on its side, open end slightly downwards, to allow the foam filler and battery to slide out. Disconnect the battery by unscrewing the terminals from the battery posts. Lubricate with silicone grease. Replace the battery by securing the two terminals to the battery posts. Assure tightness. NOTE: Connect black lead to center (-) post of battery. 2. 4 Check for proper operation by holding the top cap assembly vertical (light lens up). If the unit does not operate, check for proper battery connection. Assembly A. Hold the case horizontally and slide the battery in, terminal end up (towards the open end of the case). [. . . ] (Shipped without battery from factory) Electrical connections between the main circuit board and the associated battery are accomplished by the use of clearly marked terminals and color-coded lead wires. A matter of balance Marker lights need to float upright for maximum visibility. Although these batteries are the same size, their different chemistries cause them to have varying weights. It is imperative that only the 6 volt battery models suggested are used. [. . . ]
