Bluetooth Heart Rate Monitoring

The 7.4AT Treadmill is equipped with multi-channel Bluetooth which enables you to wirelessly connect compatible Bluetooth heart rate monitoring devices to this unit. You will need to ensure that your wireless heart rate monitoring device is Bluetooth 4.0 compatible and is also “open” to sharing data. Non-“open” or “closed” devices typically only share data with their proprietary apps. The 7.4AT Treadmill needs an “open” device to receive data from the device. You may need to consult with your device’s owner’s manual or the manufacturer to confirm if it is an open device.

How To Program And Use The Custom Interval Buttons 

  • The programmable interval buttons located on the pulse rate grips are designed to help you customize this machine to match whatever workout you like to do the most.
  • The LEFT and RIGHT INTERVAL BUTTONS are programmable for speed and incline.
  • To program the INTERVAL button, you must select a user, start the machine, set the desired speed and incline, press and hold the desired INTERVAL button for three seconds until the treadmill beeps. Now the INTERVAL button is programmed to your settings. After programming the INTERVAL button, it will remember the setting for that user until reprogrammed.
  • Now when the INTERVAL button is pressed, the treadmill speed and incline will change to the settings you programmed for that button.
  • The most common type of workout these keys will help with is interval training. We suggest programming one of the INTERVAL buttons to your high intensity segments and the other to your recovery segments.
  • Another common use is to set one INTERVAL button to your warm up and cool down settings and the other to your desired workout settings.
  • These buttons should allow you to customize the settings of your treadmill to quickly fit the type of workout you enjoy most.

Using Your Device

The 7.4AT Treadmill will connect and stream music form your compatible music device. This includes many smart phones and traditional mp3 players.

Your 7.4AT Treadmill comes equipped with Bluetooth speakers. Bluetooth compatible devices (running Bluetooth 4.0) can stream music wirelessly from your device to the speakers. You can also connect your music device via an audio cable and still stream music through the speakers. Instructions for both types of audio connection are detailed below.

Connecting Via Bluetooth 4.0

  1. Check to ensure that your music device is Bluetooth 4.0 compatible
  2. Go into your device’s Bluetooth settings and scan for devices.
  3. On your music device, locate the Bluetooth device list. Select your unit that appears on this list.
    Wait for your music device to finish pairing with the unit.
  4. You will know when pairing is successful when your music device shows the unit as now being a paired device.

When The Unit Is Powered Off Then Back On

If you turn your unit off, or if it goes into sleep mode, the next time it is powered on the unit will look to pair with the last music device with which it was paired. It will automatically pair at this time.

Re-Pairing Devices

In the event that the unit cannot find the last paired music device (for example, the music device is off or not being used) then the unit will stop looking to pair with the music device. If this happens, and if you wish to use your music device again, then you will need to go through the pairing process listed above and re-pair through your music device’s settings.

Using Multiple Music Devices

If multiple devices are being paired with the unit (i.e.: multiple users are using the unit and pairing their music devices with it) then the unit will look to pair with the last device used and “forget” other devices. If you wish to re-pair a “forgotten” music device, then you will need to un-pair the current paired device and then re-pair your device through the pairing procedure noted above.

Connecting Via An Audio Cable

  1. Connect the included AUDIO ADAPTOR CABLE to the AUDIO IN JACK on the top right of the console and the headphone jack on your music device.
  2. Use your CD / MP3 player buttons to adjust song settings.
  3. Remove the AUDIO ADAPTOR CABLE when not in use.
  4. If you don’t want to use the SPEAKERS, you can plug your headphones into the AUDIO OUT JACK at the bottom of the console. This ensures that if you accidentally catch the headphone line while running, you won’t drop your device to the ground.
