HOW TO PROGRAM AND USE CUSTOM INTERVAL BUTTONS

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.1
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.

HEART RATE ICON TARGET HEART RATE: This program is designed for you to improve your overall cardiovascular fitness levels. You simply set your target heart rate. The program will then monitor and adjust the intensity level to maintain your heart rate within your targeted range while you exercise – a proven method to maximize your weight loss and fitness goals. A chest strap is required and must be worn during the duration of this program. See below for calculating your target heart rate.

Calculating Your Target Heart Rate
The first step in knowing the right intensity for your training is to find out your maximum heart rate (max HR = 220 – your age). The agebased method provides an average statistical prediction of your max HR and is a good method for the majority of people, especially those new to heart rate training.
The most precise and accurate way of determining your individual max HR is to have it clinically tested by a cardiologist or exercise physiologist through the use of a maximal stress test. If you are over the age of 40, overweight, have been sedentary for several years, or have a history of heart disease in your family, clinical testing is recommended.
This chart gives examples of the heart rate range for a 30 year old exercising at 5 different heart rate zones. For example, a 30-year-old’s max HR is 220 – 30 = 190 bpm and 90% max HR is 190 × 0.9 = 171 bpm.

Additional target heart rate notes:
The treadmill incline will automatically adjust to bring you near your specified heart rate.
If there is no heart rate detected, the unit will not change the incline.
If your heart rate is 25 beats over your target zone the program will shut down.

Target Heart Rate Zone: Workout Duration: Example THR (age 30): Your THR: Recommend For

VERY HARD 90 – 100%: < 5 min: 171-190 BPM:  –  : Fit persons for athletic training
HARD 80 – 90%: 2-10 min: 152-171 BPM:  –  : Shorter Workouts
MODERATE 70 – 80%: 10-40 min: 133-152 BPM:  –  : Moderately long
Workouts
LIGHT 60 – 70%: 40-80 min: 114-133 BPM:  –  : Longer and frequently repeated shorter exercises
VERY LIGHT 50 – 60%: 20-40 min: 104-114 BPM:  –  : Weight management and active recovery

CUSTOM HEART RATE
CUSTOM HEART RATE:
This program allows you to set your Heart Rate for a specified time. The program will adjust incline to keep your Heart Rate in your target zone. Build multiple Heart Rate targets into a full program to help you reach your cardiovascular goals. The program total time includes a 4 minute warm up and 4 minute cool down time. Your selected custom heart rates will repeat after the warm up until 4 minutes before the total time expires.

SPRINTS 8
SPRINTS 8:
A time based program that allows you to select a level. After warm up, the program will give you 30 seconds at a high speed and intensity, alternating with 90 seconds at a lower recovery speed. Increasing levels will allow you to keep your calorie burn high and increase your overall running speed.

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.

USING YOUR MUSIC DEVICE

The 7.8AT Treadmill will connect and stream music form your compatible music device. This includes many smart phones and traditional mp3 players such as the iPod®.
Your 7.8AT 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 4.0LE

  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 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 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 MUSIC 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.

AFG TABLET CONNECTED FITNESS SYSTEM
Your Horizon machine is tablet ready, allowing you to use Bluetooth 4.0 technology to wirelessly connect your tablet to your Horizon machine. Using
the free downloadable AFG PRO FITNESS app will enable you to control your unit’s operating functions via your tablet. The app will also allow you to
monitor your workout, track your progress and view your workout history. The AFG PRO FITNESS app can be downloaded from either the iTunes store
for iOS devices or from the Google store for Android devices.
For information about connecting your tablet to your Horizon machine setting up the AFG PRO FITNESS and controlling and monitoring your workout
with your tablet, see the AFG Connected Fitness Manual included with your unit.
BLUETOOTH HEART RATE MONITORING
The 7.8AT 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 7.8AT 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.
If you are using a tablet and running the AFG PRO FITNESS app, the compatible Bluetooth heart rate monitoring device will pair automatically to the app. The machine’s console will then receive the heart rate information from your tablet. If you wish to use the Bluetooth heart rate monitoring device without a tablet and AFG PRO FITNESS app, press and hold the Bluetooth button on the console for 5 seconds. This will enable the console to communicate directly with the Bluetooth heart rate monitoring device. Heart rate information will be displayed on your console display. When in heart rate monitor mode, the console will be unable to communicate to the tablet. To enable tablet communication, press and hold the Bluetooth button on the console for 5 seconds or reset power.
