3. Maintenance
Preventive Maintenance Tips
NOTE: Safety of the equipment can be maintained only if the equipment is examined regularly for damage or wear.
Keep the equipment out of use until defective parts are repaired or replaced. Pay special attention to parts that are
subject to wear, as outlined below.
The following preventive maintenance tips will keep the product operating at peak performance:
• Locate the product in a cool, dry place.
• Clean the display console and all exterior surfaces with an approved or compatible cleaner (see Approved and
Compatible Cleaners) and a microfiber cloth.
• Long fingernails may damage or scratch the surface of the console; use the pad of the finger to press the selection
buttons on the console.
Approved and Compatible Cleaners
Two preferred cleaners have been approved by reliability experts: PureGreen 24 and Gym Wipes. Both cleaners will
safely and effectively remove dirt, grime and sweat from equipment. PureGreen 24 and the Antibacterial Force
formula of Gym Wipes are both disinfectants that are effective against MRSA and H1N1.
PureGreen 24 is available in a spray which is convenient for gym staff to use. Apply the spray to a microfiber cloth and
wipe down the equipment. Use PureGreen 24 on the equipment for at least 2 minutes for general disinfection
purposes and at least 10 minutes for fungus and viral control.
Gym Wipes are large, durable pre-moistened wipes to use on the equipment before and after workouts. Use Gym
Wipes on the equipment for at least 2 minutes for general disinfection purposes.
Contact Customer Support Services to order these cleaners (1-800-351-3737 or email:
customersupport@lifefitness.com).
Mild soap and water or a mild non-abrasive household cleaner can also be used to clean the display and all exterior
surfaces. Use a soft microfiber cloth only. Apply the cleaner to the microfiber cloth before cleaning. DO NOT use
ammonia or acid based cleaners. DO NOT use abrasive cleaners. DO NOT use paper towels. DO NOT apply cleaners
directly to the equipment surfaces.

4. Theory of Operation
Main Board (PCB-001)
Theory of Operation:
This is the main interconnection board that interfaces to the various PCBA’s in the console. There are two processors
on this board. One is an i.MX8 quad core processor that runs the workout logic, drives LED displays, reads keypads,
and services USB and wireless devices. The other processor is a Kinetis K17 MCU that does the Life Pulse and Polar
processing. This board is considered “not serviceable”, due to the inability to program certain data (QR code, Console
s/n, etc.) in the field. If this board is determined to be faulty, the entire console should be replaced.
Page 11 of 153

Functions/Connectors:
J1 Base Power Contains power (+12 VDC or +24 VDC) from base, plus Verp and E-Stop signals.
J2 Base Signal Contains handlebar buttons, E-Stop (to magnet/tether), Life Pulse signals.
J3 Attachable TV Contains R/L audio input and TV detect signal from TV, plus IR control signal to
TV.
J4 Base Communication Contains RS-485 Rx & Tx twisted pairs from base.
J7 Audio Out Contains Audio R/L output to / headphone detect signal from Headphone Jack.
J8 Polar Contains +3.3 VDC power to / telemetry pulse input signal from Polar RE-07
board.
J10 NPE Contains +3.3 VDC power, UART, I2S, and reset signals to North Pole Eng’s GEM
Module (supports BLE / GymKit / NFC).
J11 Keypad switches (Flat flex) Contains matrix of 7 strobes x 7 returns to read console buttons, plus Go, Stop
and Detect signals.
J12 Keypad LEDs (Flat flex) Contains 17 low-side LED drive signals, +5 VDC for high side of the LEDs, and a
Detect signal.
J13 Message Center (Flat flex) Contains +3.3 VDC & +5 VDC power, SPI port, and 4 GPIO (used with LCD) to
Message Center board.
J14 USB (User) Contains USB signals (+5 VDC and D+/D-) to user accessible USB port at console
front.
J15 USB (Wireless connectivity /
Bluetooth)
Contains USB signals (+5 VDC and D+/D-) for combined Wireless connectivity /
Bluetooth dongle.
J17 CSAFE Contains VCardio (+5 VDC), R/L audio input (from MyE device), UART, and Test
Mode Enable signal.
Troubleshooting tips:
• Make sure that all the connectors are properly seated and that there are no pinched cables between any of these
connections.
• In normal operation, a green LED blinks to indicate the K17 processor has power and is communicating with the
i.MX8 processor.
• In Diagnostics, do the LED test to light up all LED's in the keypad, Message Center, and Hill Profile / Speed Zone
boards. Also do the keypad test to test every button on the console’s keypad (plus the speaker).
Page 12 of 153

Message Center Boards (PCB-002)
Theory of Operation:
There are three total Message Center boards: two sizes of LED Message Center boards plus the LCD Message Center
board. The Treadmill’s LED Message Center board has twenty-six 14-segment LED characters, while the Non-
Treadmill’s LED Message Center board has twenty 14-segment LED characters. The same LCD Message Center board
is used on both Tread and Non-Tread consoles. The LCD Message Center board has a 288x16 pixel LCD for displaying
languages and characters that cannot be displayed with 14-segment LED's. All three Message Center boards have the
same connectors and use the same Kinetis K17 processor.
Functions/Connectors:
J1 Main Board (Flat flex) Contains +3.3VDC & +5VDC power, SPI port, and 4 GPIO (used with LCD) from
Main Board.
J4 Spare I2C port For development and future use. Not populated.
J7 SWD pads For development and programming of Kinetis K17 processor. Not used in

J9 K17 debug UART For development and debug of K17 processor. Not populated.
J10 Chassis Ground tab.
J12 Hill Profile / Speed Zone (Flat
flex)
Contains +3.3VDC power, I2C port, SPI port, 10 high-side LED drive signals, two
Board ID signals, and Detect signal to Hill Profile / Message Center board.
Troubleshooting tips:
• Try unlatching the zero-insertion force (ZIF) connectors, fully inserting the flex cables, and re-latching the
connectors to ensure that both flex connectors are fully seated.
• Upon power-up (ie. until the Main board’s i.MX8 is done booting up and can command the PLEASE CHOOSE A
WORKOUT... message), the Message Center board initially blinks LF on its 14-Segment LED's. If the Message
Center board is the LCD version, it will blink LF on the Hill Profile / Speed Zone board.
• In Diagnostics, do the LED test to light up all LED's on the Message Center boards.

Hill Profile Board (PCB-003)
Theory of Operation:
The Hill Profile board is only used on Integrity SL consoles. It contains a rectangular array of 7x15 LED's that comprise
the Hill Profile. All Integrity SL consoles use the same board. It does not have a processor on the board. Its data and
LED's are driven by the Message Center boards.
Functions/Connectors:
J1 Main Center (Flat flex) Contains +3.3 VDC power, I2C port (not used by Hill Profile board), SPI port, 10 high-
side LED drive signals, two Board ID signals, and Detect signal from Message Center
board.
J10 Chassis Ground tab.
Troubleshooting tips:
• Make sure that the flex connector is fully seated. Try unlatching the zero-insertion force (ZIF) connector, fully
inserting the flex cable, and re-latching the connector.
• Upon power-up, while the Main board’s i.MX8 is booting up, if the Message Center PCBA is the LCD version, it will
blink LF on the Hill Profile board.
• In Diagnostics, do the LED test to light up all LED's on the Hill Profile board.

Polar Board (PCB-005)
Theory of Operation:
The Polar board is an off-the-shelf RE-07 telemetry receiver board from Polar, Inc. It receives HR pulses from the user’s
telemetry chest strap. The pulses may be coded or uncoded depending on the type of telemetry strap. If coded, the
chest strap must first be within ~25” of the Polar RE-07 receiver (which is centered directly behind the console’s
reading rack). Once the HR is displayed, the code is locked in and the user’s chest strap or simulator can be moved
back to ~35”. Uncoded chest straps have the same reception range (~35”).
Functions/Connectors:
Connector to Main
Board
Contains +3.3 VDC and Ground from the Main board and telemetry pulse signal to Main
board.
Troubleshooting tips:
• Make sure that the connectors are properly seated at the Main board and at the Polar board. Make sure the cable is
not pinched or severed (try a different, known good, cable).
• In a workout, press the right toggle button so that the Heart Rate LED is lit. Set a Polar simulator to between 60 -
200 bpm and place it in the reading rack. Observe the HR value changes up or down as the HR setting on the
simulator is changed.
• Polar reception range is significantly reduced by any metal in the reading rack. Be sure there are no metal devices
(cell phone, tablet, iPod, Kindle, etc) in the center of the reading rack. Remove device entirely to see if it is
interfering. If user desires to use the device and Polar simultaneously, they must move the device to a cup holder or
off to the side of the reading rack.

Headphone Jack Board (PCB-008)
Theory of Operation:
Audio out is provided via a Headphone Jack board. The Headphone Jack board is inside the angled, over-molded
assembly and is screwed into the rear bezel. The board also has TVS (Transient Voltage Suppressor) devices to shunt
ESD energy to the chassis. This part is easily serviceable.
Functions/Connectors:
Connector to Main Board Contains Right / Left analog audio, headphone detect, and ground from the Main board
and shield ground to the chassis.
Headphone Jack Contains Right / Left analog audio, detect, and ground.
Troubleshooting tips:
No sound: • Plug headphones into the Headphone Jack board.
• Make sure that the connectors are properly seated at the Headphone Jack PCBA and Main
board.
• Make sure the headphone jack cable is not pinched or severed.
• Try a different, known good, cable.
• Verify the audio source’s volume (Attachable TV or MyE) is not muted or very low.
• Verify that the media buttons control the TV or MyE device and power is on to the TV or
MyE.
• Verify that the cables to the Attachable TV or MyE device are connected properly.
• Verify that the headphones are good.
Distorted sound: When wiggling the headphone connector that is plugged into the Headphone Jack board, if
the sound is distorted, cracks, or pops, then replace the Headphone Jack board.
