41.  IntroductionThe Guardian MOB Beacon Watch is a full function alarm chronograph whichincorporates an emergency distress transmitter. The transmitter may be activatedautomatically if the Watch is immersed in water; it may also be activated manually.This product is designed to be worn in conditions where the user is at risk of fallinginto water and where it may be difficult to locate the person in the water visually. Thebeacon is used in conjunction with a receiver to generate an alarm; a  directionfinder is available to help locate the person in the water.1.1  Man Overboard OperationOnce armed, the beacon will activate automatically when immersed in sea water,and will continue to transmit until disabled. Arming and disabling are detailed in theFeatures section. In fresh water the beacon must be activated manually.The beacon cannot transmit effectively when underwater, and needs to be as highas possible for best signal range. Ideally, the user should hold up the arm wearingthe watch, but this is impractical for long periods. It is recommended that the arm isrested on top of the lifejacket, as shown opposite.
51.2  Battery LifeThe battery is designed to power this product for a period of 1 year.When the battery is running low the LED flashes and the sounder beeps four times,repeating every minute. This warning normally indicates that the battery hasreached the minimum level at which performance can be guaranteed; any furtherdeterioration may jeopardise the performance of the beacon in an emergency.Refer to Page 15 for information on testing the beacon to verify the alarm.Refer to the Service section for information on replacing the battery.Beacon transmitting in emergency
