WEARING THE HEART RATE TRANSMITTER STRAP
REPLACING THE TRANSMITTER BATTERY
The Loft unit features a wireless heart rate transmission system. This system features a heart rate transmitter which
is worn on your chest. Like the watch unit, the transmitter is powered by a CR2032 3v Lithium battery. Under normal
conditions you can expect to get approximately 700-800 hours of transmitter use with a fresh battery.
1. Using a coin that closely fits the slot in the battery door located on the back of the transmitter, turn the
battery door counter clockwise until the door comes free of the transmitter body.
2. Take care not to damage the O-ring seal for the battery compartment and carefully remove the old
battery.
3. Place a fresh battery in the battery compartment with the positive (+) side facing up.
4. With the O-ring in the proper position, place the battery door over the opening and tighten it down by
using a coin and turning in a clockwise direction.
5. If the O-ring has been damaged, replace it before reinstalling the battery door. Most jewelers and
watch shops should have replacement O-ring seals.
Extreme care should be taken when replacing the battery to ensure the unit remains fully water resistant. Failure
to properly replace the battery and correctly seal the unit may cause the unit to become damaged and may void
the warranty.
The heart rate transmitter strap consists of two conductive electrodes attached to a small radio transmitter housed in
the center of the strap. The electrodes sense the electrical potential created each time your heart contracts and the radio
transmitter sends a signal to the watch each time the electrodes sense the heart beat. For the best performance, a layer of
sweat should be built up between your skin and the electrodes of the transmitter. This makes it easier for the electrodes to
"see" the electrical signal. On cool days or at the beginning of your workout it may be necessary to moisten the electrodes
on the back of the transmitter using saliva or on of the commercially available electro conductive creams. DO NOT use tap
water to moisten the electrodes as tap water will act as an insulator rather than a conductor and may actually reduce the
performance of the system
The transmitter should be worn around the rib cage, just below the pectoral muscles. The elastic strap of the system should
be adjusted so that it is snug enough so it does not move during use, but not so tight as to restrict breathing. While the
wearing of the transmitter strap may feel a bit strange initially, most people become used to in within a few days and cease
to even notice they are wearing it.
INTERFERENCE
For reasons of size, cost and battery life, heart rate monitors function using a very low transmission frequency. Because
of this they are susceptible to interference from a variety of electromagnetic and microwave sources. High tension power
line, traffic light controls, home and automotive electronics, powered exercise equipment, home security and wireless
LAN systems and other things may interfere with the ability of the system to register a heart rate. Intermittent readings
of zero or of very high heart rates (exceeding 210 beats) are an indication of some type of interference. In general, the
interference caused by these sources is localized. After a few seconds or at most minutes, you should pass from the area
of interference and the operation of the watch should return to normal. Additionally, other heart monitors close by may
also interfere with the function of your unit. It is recommended that you separate yourself from other heart rate users by
a minimum of 3 feet (1 meter) in all directions.
