+
+2. Check if the LED is...
+    + ***Hard flashing pink light*** <span class="led sd-error"></span>. In this case, your kit **IS NOT** storing data.
+    + ***Soft fading pink light*** <span class="led sd"></span> with either orange <span class="led sd-chargebat"></span> or green intermitent light <span class="led sd-fullbat"></span>. In this case, your kit **IS** storing data.
+    + ***A single green light with less frequency*** <span class="led sd-sleep"></span>. Your kit **IS** storing data.
+3. If your kit is **NOT** storing data, you need to follow the steps below using a mobile phone:
+    + If you have an iPhone, [follow these steps](#setup-for-iphone)
+    + If you have an Android phone, [follow these steps](#setup-for-android)
+
+Below you have a summary of all the possibilities:
+
+| LED color                            |  Kit status                             |

+| <span class="led sd-warning"></span>    | :warning: Warning. Collecting data but not storing it in sdcard       |
+| <span class="led sd-error"></span>       |  ❌ Error. Not collecting data         |

+
+2. The LED from before should now be **red**.
+
+3. Next, on your iPhone, tap **Settings** > **Wi-Fi**. Your device searches for available Wi-Fi networks and displays them in a list. The kit will appear as `SmartcitizenXXXX`. The last four digits will match the four digit code printed on the kit (on the blue face of the outside, on the gray box inside the box, or both). For example: `SmartcitizenA0D`.
+
+4. Tap the name of the network, then wait for a welcome page to appear.
+
+    !!!warning
+        If the captive portal page doesn’t appear or you accidentally closed the page, you can force it to reopen by typing `sck.me` in the any browser search field.
+
+
+5. Now, you can press on the "Offline mode (SD-Card)" button:

+7. The LED should be ***Soft fading pink light*** in any of the modes below. Below you have a summary of all the possibilities:
+
+    | LED color                                |  Kit status                                |
