How to program and use custom buttons

• The programmable interval buttons and the split key are designed to help you customize this machine to match whatever workout you like to do the most.
• The INTERVAL 1 and 2 keys are programmable for speed and incline. They will also reset the SEGMENT TIME to 0 seconds when pressed.
• To program the INTERVAL key, you must select a user, start the machine, set the desired speed and incline, press and hold the desired INTERVAL button until the treadmill beeps. Now the INTERVAL key is programmed to your settings. After programming the INTERVAL key, it will remember the setting for that user until reprogrammed.
• Now when the INTERVAL key is pressed, the treadmill speed and incline will change to the settings you programmed and the segment timer will reset to 0 seconds.
• The most common type of workout these keys will help with is interval training. We suggest programming one of the INTERVAL keys to your high intensity segments and the other to your recovery segments. The SEGMENT TIME helps you keep track of how long you have been in your current segment.
• Another common use is to set one INTERVAL key to your warm up and cool down settings and the other to your desired workout settings.
• Use the SPLIT key anytime you want to reset SEGMENT TIME to 0.
• These keys should allow you to customize the settings of your treadmill to quickly fit the type of workout you enjoy most.

Finishing your workout

When your workout is complete, the unit will beep. Your workout information will stay displayed on the console for 30 seconds and then reset.

Bluetooth Heart Rate monitoring

The T303 is equipped with multi-channel Bluetooth which enables you to wirelessly connect compatible Bluetooth heart rate monitoring devices to this treadmill. 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 T303 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.

Pair the receiver to the app and the console will receive the information from the tablet. To use the Bluetooth chest strap without a tablet, press and hold the Bluetooth button to enable the console to communicate with the receiver. When paired with the chest strap the console will not pair with a tablet. To enable tablet communication press and hold the Bluetooth button for 5 seconds or reset power.

Using your music device

The T303 treadmill will connect and stream music form your compatible music device. This includes many smart phones and traditional mp3 players.

Your T303 comes equipped with Bluetooth speakers. Bluetooth compatible devices can stream music wirelessly from your device to the speakers. You can also connect your music device via an audio cable and stream music through the speakers. Instructions for both types of audio connection are detailed below.

Connecting via Bluetooth 4.0LE

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 treadmill or elliptical 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 treadmill or elliptical unit as now being a paired device.

When the unit is powered off then back on

If you turn your treadmill or elliptical 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 devices

If multiple devices are being paired with the unit (i.e.: multiple users are using the treadmill or elliptical 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.
