1 PURPOSE
The purpose of this document is to provide a user overview of the FIT1/e Module, for RF certification and
regulatory purposes.
2 OVERVIEW
The FIT1 and FIT1e (denoted ‘FIT1/e’ in shorthand) are OEM Printed Circuit Board Assemblies (PCBAs) that
are designed specifically for integration inside fitness equipment to enable communication with RF devices
such as heart rate monitors (HRMs) and watches.

The FIT1 is a RF-only module, which operates on the 2.4 GHz license-free band and is capable of bidirectional
communication. The FIT1e includes the FIT1 functionality but also incorporates an electromagnetic (EM)
receiver coil that is capable of receiving 5 kHz inductive pulses from legacy HRM transmitters. The intention is
for either module to be pre-certified as intentional transmitters, providing customers with ease of integration and
reduced time to market. This document reviews the operational characteristics, applicable markings, labels and
warning required for the various regulatory jurisdictions.
3 FIT1/E OPERATION
3.1 Proximity Linking
Pairing between FIT1/e and compatible RF-based HRMs and watches is accomplished through a process called
‘proximity linking’, which discriminates against non-proximal devices using received signal strength indication
(RSSI). In practice, proximity linking is performed by having the user bring the RF device close to the fitness
console, where the FIT1/e module is located. Once linked, the devices maintain communication within a much
larger tracking zone. If an EM-based HRM is being used, then the pairing process is not applicable.

3.2 Fitness Equipment States
It is important for the FIT1/e to know the state of the fitness equipment. The fitness equipment state
determines when the FIT1/e will search for devices and allows the FIT1/e to send control messages
(start/stop) to a paired watch. These functions are handled by the FIT1/e in order to:
1) Simplify the implementation for fitness equipment manufacturers.
2) Provide a consistent end-user experience across different fitness equipment implementations.
3) Provide optimal power management
FE State Descriptions FIT1e Activities
ASLEEP (OFF) – This state applies any time
that the FIT1e is turned off or in a power
saving sleep mode.
FIT1e is in low power mode.
READY – When the FIT1e is turned on or
activated, it will start in READY state,
waiting for a user to initiate a workout
session.
FIT1e is searching for heart rate monitors and
watches to pair to. Because some FE, like
treadmills, may be in READY state for indefinite
periods of time, the FIT1e pairing search does not
time out.
IN USE – This state corresponds to an active
session on the FE. The chronometer begins
running.
The FIT1e continues searching for heart rate
monitors or watches for 30 seconds after the FE
state switches to IN USE. If none are found, the
FIT1e goes to a power saving mode.
If the FIT1e is paired to a heart rate monitor, it
receives heart rate data and passes it to the FE.
If the FIT1e is paired to a watch, it:
1) sends a message to the watch to start its
chronometer

2) receives watch files, and
3) begins broadcasting FE data to the watch
FINISHED – This state applies when the user
stops a workout session, either to pause or to
finish.
The FIT1e remains paired. If there is a watch
paired, the FIT1e sends a message to stop the
watch’s chronometer.
4 FIT1/E INTERFACE
4.1 Electrical Interface
0.050” (1.27mm) dual row 12 Pin header, with pinout as follows:
FIT1 and FIT1e operating voltage limits: 3.0 to 10.0 V
Baud rate adjustable: 9600, 19,200 & 57,600 baud rates supported.
4.2 Mechanical Interface and OEM Installation Guidelines
For the FIT1/e to operate correctly it is important to note some restrictions for mounting the module:
1. Do not place metallic objects in contact with the Antenna, Shield, EM coil (on FIT1e) or any
other components on the PCB, with the exception of the electrical connection to the header and
fastening screws. See Figure 3 for component identification.
2. Reducing the quantity and volume of metallic objects in the vicinity of the FIT1/e will allow for
improved RF and EM (on FIT1e) performance.
3. The use of non-metallic paint is required for all enclosures for the FIT1/e. Using metallic paint
will severely degrade RF and EM (on FIT1e) performance, affecting pairing ability and module
communication.

4. For large consoles (width greater than about 1.5’ or 45 cm), the FIT1/e should be located in the
middle third of the console, not to the right or left sides. This requirement helps to ensure that
the FIT1/e pairs with the user on the equipment and not a neighbor or passer-by. Please see
Figure 2 for details. For the FIT1e to achieve optimal EM range, place the FIT1e as close to the
user as possible within the console.
5. When determining mechanical fastening methods minimize material on or around printed
antenna (on both sides of PCB) and the EM coil (on FIT1e). Placing material in these areas will
affect the radiation pattern, potentially degrading performance. See “Printed Antenna Keepout”
in Figure 3. If possible, the module should be placed on or close to the front plastics of the
console or enclosure.
6. It is important that the FIT1/e is not placed behind the LCD or PCBs of other electronics within
the console/ enclosure. The RF and EM (on the FIT1e) circuit provide much greater reliability if
line of sight is available between the module and the user, with only the console/ enclosure
plastics in between. In some applications space does not allow for the module to adhere to this
guideline. In these cases the module can partially sit behind PCB material provided that it is free
of ferrous or nickel metals. This case should be avoided if possible.
For the FIT1e, it is important that the module is positioned away from sources of electric noise such as
fans, motors, generators etc. Devices causing large amounts of electrical noise, degrading EM signal.
LCD screens may also cause noise to the EM circuit. If possible position the FIT1e away from LCD
screens. If this is not possible, maximize the distance from the LCD screen to the module.

4.3 FIT1/e Orientation inside Fitness Equipment Console
The module orientation is an important factor to mounting the FIT1/e. Acceptable orientations differ
between FIT1 and FIT1e, as a result of EM functionality. As there are many factors that affect radiation
patterns the best results can be achieved by experimenting with the orientations on an individual device
basis.
In general the FIT1 should be positioned such that the antenna sits horizontal to the user’s HRM (i.e. the
long side of the FIT1 is parallel to the floor). Other orientations are possible for the FIT1 but are not
recommended as they will reduce the effectiveness of the RF circuit.
The FIT1e requires that the EM coil sit horizontal to the user’s HRM (i.e. the long side of the module is
parallel to the floor). This is due to the limitations of the RF radiation pattern. Because of this
requirement FIT1e units have few possible orientations.
5 REGULATORY REQUIREMENTS
