1. Introduction
The Guardian MOB Beacon Watch is a full function alarm chronograph which
incorporates an emergency distress transmitter. The transmitter may be activated
automatically 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 falling
into water and where it may be difficult to locate the person in the water visually. The
beacon is used in conjunction with a receiver to generate an alarm; a direction
finder is available to help locate the person in the water.
1.1 Man Overboard Operation
Once armed, the beacon will activate automatically when immersed in sea water,
and will continue to transmit until disabled. Arming and disabling are detailed in the
Features section. In fresh water the beacon must be activated manually.
The beacon cannot transmit effectively when underwater, and needs to be as high
as possible for best signal range. Ideally, the user should hold up the arm wearing
the watch, but this is impractical for long periods. It is recommended that the arm is
rested on top of the lifejacket, as shown opposite.
1.2 Battery Life
The 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 has
reached the minimum level at which performance can be guaranteed; any further
deterioration 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.

4.1 Battery change
It is not recommended to attempt to replace the product battery, as this is a task for
a skilled specialist. It is advisable to return the product to McMurdo, or to take it to a
McMurdo Service Agent.
A kit containing all necessary parts and instructions is available. The product must
be fully tested after battery replacement. It is essential that a pressure test is
performed to ensure that the housing is waterproof, as otherwise the
lifesaving capability of the beacon may be compromised.

5. Training Watch
The Training Watch is identical to the Guardian MOB Beacon Watch in operation,
except that it transmits on 121.65MHz. As a consequence its signal cannot be
received on normal distress alarm receivers, thus training exercises may be
conducted without creating false alarms. The training watch is clearly identified by its
strap markings.
NEVER WEAR THE TRAINING WATCH EXCEPT FOR TRAINING EXERCISES.
The MOB Emergency Receiver has a special listening mode designed for use in
training exercises.
14
6. Battery reset
Under certain conditions, typically when the beacon has activated for short periods,
the low battery alarm may sound although the battery does not need to be replaced.
If this is suspected, the battery alarm function should be reset by:
Press and hold the CONFIRM button
Press the ARMING button once
Release buttons. The unit will acknowledge with 5 beeps.
Immediately press the CONFIRM button twice. The unit will
acknowledge with a LED flash.
Immediately press the ARMING button once. The unit will
acknowledge with 4 beeps.
Confirm that the low battery alarm has been reset by monitoring
the Beacon for 2 minutes.
If the alarm does not sound, the Beacon may be used as normal.
If the low battery alarm sounds at this time or subsequently, a new battery
must be fitted.
