ACR Electronics SM-2 STROBING MAN-OVERBOARD LIGHT Product Support Manual page 2

Congratulations and thank you for purchasing the ACR SM-2 Automatic Crew-Overboard Light. The
combination of superior design, high quality raw materials and quality controlled manufacturing produces a
product that will perform for years to come. The Test Facility at ACR can reproduce some of the harshest
environmental conditions known to man. This assures that the products we design and manufacture can
stand up to the rigors found in a marine environment. With proper care and maintenance, your SM-2 light
will be in service for years to come.
ACR is proud to be certified to the ISO 9001:2000, the International Standard for Quality.
This manual provides installation, operation and maintenance instructions for the SM-2 light.
In order for the marker light to float properly, the 6 volt battery MUST not weigh more than 675 grams
(1.49 lbs). Exceeding this weight will cause the light to sink.
