Dynaflex II Go User Guide

Unboxing and Plugging In

1. Unbox the Dynaflex II Go and ensure that all components are included:
   1. Dynaflex II Go device
   2. Short USB-C - USB-C cable (for connecting to mobile device)
   3. Long USB-A - USB-C cable (for charging)
2. Plug the device in with one of the USB cables provided to ensure it has a full charge before your event. A tone should ring and light(s) should blink continuously at a constant rate.
3. Navigate to SaffireTix settings on your mobile selling device and ensure that the "Magensa Only" setting is turned ON. This will allow the app to connect to the card reader.
4. Connect the Dynaflex II Go with your mobile selling device via Bluetooth or USB-C cable. Information and instructions for both options are available below.
5. For use with laptop kits, follow the instructions for setting up the Dynaflex PED card reader here.

Connecting via Bluetooth

Connecting via Bluetooth provides a reliable connection for payment processing, but means the card reader will be running off of its own internal battery. Battery life on these card readers has been tested in the field up to 6 hours with no issues and may be good for much longer, however a battery backup or additional units to swap out may be a good precaution for long selling shifts in remote locations.

To connect via Bluetooth:

1. Turn on DynaFlex GO by holding the power button until 1 beep is heard.
2. Connect DynaFlex GO to your device Bluetooth by first holding the power button again for 4 audible beeps, then connecting to it via device settings in the android device. Pin for DF-GO's Bluetooth is six zeros. (000000)
3. Prepare a test transaction by adding a product to the app shopping cart.
4. Click Credit Card payment option.
5. Select "Connect to Reader"

   

   
   
6. Select the Bluetooth device with the serial number that matches the number on the back of the device. If you are not able to find the serial number, taking the device away from other card readers will narrow the options to only the device you have with you.
7. When successful, the app should display Connected To: Dynaflex II Go.

8. It is always a good idea to run a test transaction to ensure the payment gateway is functioning before you attempt to use the device for customers.

   
   

Connecting via USB-C

When connected to your mobile selling device via USB-C, the card reader will be powered by the selling device battery. Connecting via USB-C offers a generally reliable connection, however USB ports can at times be finnicky. It is always a good idea to ensure sellers know how to follow the Bluetooth instructions above in case of the need to switch to the device's internal battery.

To connect via USB-C:

1. Using the included USB-C - USB-C cable, plug the device into a mobile scanner that is logged into the SaffireTix app. Solid or blinking green lights on the card reader indicate the device is connected.

Checking Battery Levels

The Dynaflex II Go device can have lights on yet still function improperly due to a low battery level right before it dies definitively. Holding the power/action button for 6 audible beeps will display the battery level of the device. (Power button functions from the device manual included below).

Using with Laptops and Box Office

The Dynaflex II Go can also be used with laptop kits for box office transactions. To set up this card reader for use with a laptop, follow the instructions for setting up the Dynaflex PED card reader here.

How to Complete a Transaction

Handling to Prevent Tamper Mode

The DynaFlex II Go has built-in security features designed to protect your business. One of these is tamper mode. If the device detects signs of physical intrusion, damage, or abnormal conditions, it will immediately disable itself and erase its secure data. This ensures sensitive payment information cannot be accessed by anyone who might try to compromise the reader.

While this protects your business and customers, it also means the device cannot be recovered once tamper mode is triggered — it must be replaced through MagTek. Proper handling helps you avoid accidental tamper events and maximize device life.

• Avoid plugging/unplugging rapidly — let the device fully power down before reconnecting (about 10 seconds). This prevents power spikes that can trigger tamper mode.
• Keep the reader in normal operating temperatures. The device is certified for operation in temperatures 32°F to 95°F.
• Prevent exposure to rain, spills, or any liquids. Even small amounts of moisture can trigger tamper mode.
• Use padded cases or the original packaging when storing or transporting the device.
• Do not leave the reader in vehicles or environments with temperature/humidity extremes.
• Plug and unplug USB-C cables straight in and out — avoid wiggling or pulling at an angle.
• Protect against drops, crushing, or strong impacts.

Troubleshooting

"No card reader connected, connect shuttle card reader"

This indicates that Magensa has not been enabled in the app settings. To enable, open the settings by tapping the gear at the bottom of the screen. Turn on the setting for "Magensa selling only", then continue with connection instructions above.

Device Not Showing in Dropdown

If the device is not showing in the dropdown option for either the kiosk or the box office, please check that the Google Chrome settings are allowing the device to connect with your local network. Here are the steps on how to confirm these settings:

• Step 1: Select the 'power dots' on the top right corner of the browser and select "Settings"

• Step 2: Select "Privacy and Security" and "Site Settings"

• Step 3: Select "Additional Permissions" under the "Permissions" section.

• Step 4: Scroll down to the bottom of that section and select "Local Network Access"

• Step 5: Change to "Ask" or "Sites can ask to connect to any device on your local network"

Once the steps are completed, refresh the box office browser or close Chrome and re-open the kiosk browser. The browser should then show the following pop-up to allow you to connect the device when plugged in.

If the device is still not showing in the drop-down, please check if powder is installed in the device, or it may need to be installed/reinstalled. Here is the link to the article: Dynaflex Powder Installation

Device beeps, blinks, then shuts down

What do the beeps mean when I hold the power button?
