WEARING THE CHEST BELT

You must wear the chest belt to measure your heart rate.

NOTE This OUTBREAKER watch is specially designed to work with the chest belt with which it was sold. It is not recommended you use any other chest belt with this watch, as the transmission may not work.

Diagram	Instructions
	1.	Wet the conductive pads on the underside
		of the chest belt with few drops of water or a
		conductive gel to ensure a better, solid con-
		tact.
	2.	Put on the belt, wrapping it around the upper
		chest so the heart rate monitor is in the
		middle of the chest, tucked snugly under the
		pectoral muscles.
	3.	Adjust the belt for comfort and best contact
		with the skin.

Tips: The transmission from the belt is dependent on good contact with the skin and proximity to the receiver watch. Make sure the transmitting section of the belt is against the skin, not blocked by chest hair, and close enough to the receiver watch (approximately 30 inches) to send a clear signal. Sweat or gel can help to improve the signal, and remember it is not instan- taneous. If no signal is received immediately, wait for a few seconds for the signal to get through.

NOTE An old battery may weaken the transmission and recep- tion power. Replace the battery if the performance is progres- sively worse.

Once you have good contact with the chest belt, will begin to flash. This means the signal is being sent and your heart rate will soon appear in place of the large 0. Your heart rate will be displayed as the larger font in every screen of this Mode, and can also be displayed in a smaller font, below the line, while in BIKE Mode. If you remove the chest belt, or the watch is moved too far away from it, the signal will be broken.

NOTE The CARDIO Mode will stop functioning after no signal is received for 5 or more minutes.

NOTE When you are measuring your heart rate, keep the watch away from signal generating sources, such as TVs, PCs, and car engines, as these may impair the reading.

TRAINING ZONES

The OUTBREAKER watch is equipped with a special Training Zone feature that allows you to pre-select the optimal heart rate range (50-240 beats per minute) for your activity. For example, the amount of exertion required for a stroll in the park is

different from the amount of exertion required for weight lifting to build muscle mass. With the Training Zone feature, you can set and then monitor the upper and lower heart rate limits (Training Zone) that best support your training activity and goals.
