Top Tips for Successful Measurement

Successful Data Transmission

Click and hold the power button to turn on the Tenovi Peak Flow Meter and connect to the Tenovi Gateway. Wait for the Tenovi Gateway LED to spin yellow, then proceed to take your measurement. To take additional measurements while the device is still on, click the power button and when the screen says “go”, blow into the mouthpiece. The Gateway LED will not spin yellow for back to back measurements.

Ensure Proper Usage

Remove any food or gum from your mouth before using the Tenovi Peak Flow Meter.
Cover the mouthpiece fully with your mouth, ensuring there are no air leaks.
Blow strongly and firmly into the mouthpiece.

Setup & Use Steps

Power Gateway

Step 1: Set up your Gateway by plugging it in. It will flash purple as it connects and then settle to a solid red color when it is connected.

Install Batteries

Step 2. Install batteries into the back of the Tenovi Peak Flow Meter.

Connect to Gateway

Step 3. Stand within 20 feet of the Tenovi Gateway, press the power button for 3 seconds and wait for the Tenovi Gateway to start flashing yellow.

Take A Measurement

Step 3. Take a deep breath and then exhale quickly into the Tenovi Peak Flow Meter. Make sure your mouth is fully covering the mouthpiece.

Displaying Measurement

Step 3. Your measurement will be displayed on the Peak Flow Meter screen and the Gateway LED should turn green. Press the power button and start at Step 3 if you need to take another reading.

When Taking a Measurement

Before You Measure

Remove any food or gum from your mouth.
Stand up or sit up straight. Do not slouch. Your lungs must be fully expanded to get the best reading.
Remove any tight clothing, belts or neckties that might restrict your chest or abdominal movement.

Using Your Peak Flow Meter

Inhale deeply, filling your lungs with air.
Keep your chin slightly lifted and neck extended to straighten your airway.
Put the mouthpiece fully into your mouth and seal your lips tightly around it. Do not let any air leak out the sides.

Device Specifics

Pairing and Bonding

The Tenovi Peak Flow Meter will connect automatically out of the box during the measurement.

Click and hold the power button on the meter to turn it on.
The Gateway LED will spin yellow indicating the Gateway is connected to the meter and ready to receive data.

Storage Events

The Tenovi Peak Flow Meter does not store measurements. This means if you take readings away from the Gateway, those readings will not be sent to the Gateway upon the next successful connection cycle.

Maintenance

Main unit: Wipe with a soft dry cloth. Do not put it in water. Cleaning once a week is recommended.
Mouthpiece: Use medical alcohol to clean. Then wipe clean with a clean soft cloth. To ensure the safety and hygiene during use, it must be cleaned after each use.

Device Reissue

If this is a replacement device please visit the Tenovi Web App for further assistance.

The Tenovi Peak Flow Meter is compatible with Gateway firmware 1.90.11 and later. Using a Gateway with an earlier firmware version may cause connectivity problems.

Gateway Basics

Getting Started

This means that the Gateway is trying to connect to a cell tower. Once connected to a cellular network, the Gateway will turn RED. If it goes RED and back to PURPLE , it’s looking for the strongest signal. The Gateway will go from PURPLE to BLUE if it can’t find a signal.

Taking A Measurement

1. Take a measurement with the Tenovi device(s) included with the Gateway.
2. When the Gateway is RED it’s ready for you to take your daily measurement. The Gateway LED will turn YELLOW while a measurement is being taken, and will flash GREEN when the measurement has been successfully transmitted.
3. The LED will remain GREEN for the remainder of the day, however you can take as many additional readings as necessary and all readings will transmit.
4. The LED will revert back to RED everyday at midnight, acting as a reminder to take a reading every day.

Steps to Whitelist Device

Prepare the Environment: Ensure that the only device near the Gateway is the one you want to add to the whitelist. All other devices should be at least 3 feet away. Plug the power cable into the Gateway.
Position the Device: Place the device you want to whitelist as close as possible to the Gateway.
Activate Whitelist Mode: Press and hold down the button on the Gateway until you see a pulsing white light.
Take a Measurement: Use the device to take a measurement. Once the Gateway connects to the device, the pulsing white light will stop. You will see the normal connection sequence, and when it is done, a white light will appear near the top of the LED ring.
Verify Whitelisting: Ensure that the LED ring displays a white section at the top, indicating a successful whitelisting attempt.
Repeat these steps for each device you need to whitelist. If you need to remove a device from the whitelist, disconnect the Gateway from power, press and hold the center button while reconnecting to power, wait for a beep and flash, then release the button.
