We’re hoping it will bring happiness and safety to your entire family. For a better user experience, please read this user manual carefully. Do not hesitate to contact us if you have any question. [email protected] 1-(844) 260-4051 COMPONENTS Hold down the POWER BUTTON for 5 seconds to turn the TickTalk 4 on or reboot the TickTalk 4. Hold down the SOS BUTTON for 5 seconds to call the preset SOS number. Quick tap the POWER BUTTON once then SOS BUTTON twice to call 911 instantly. COMPONENTS MICROPHONE SPEAKER Both the speaker and the microphone are protected by WATERPROOF IP67. Do not pierce with sharp objects. CHARGING Please use the 5V USB charger that connects to the charging cord in order to charge your TickTalk 4. If the cord is broken stop using it immediately. For safety reasons, we recommend that an adult supervise their child while charging the TickTalk 4. Put the charging head onto the metal pins on the back of the TickTalk 4. Make sure the metal charging port is connected to the metal charging connector of the charging cord. You’ll hear a sound when the TickTalk 4 gets started to charge. It will take 3 hours to fully charge the TickTalk 4. ACTIVATE THE SIM TickTalk is not affiliated with any wireless carriers. A free Red Pocket SIM kit is provided with your purchase. Other carriers were considered but Red Pocket was able to provide a more affordable monthly plan for TickTalk users. Be aware that this is subject to change. Red Pocket is a US based pre-paid carrier. They work with AT&T and T-mobile's network. For customers outside of the US or customers who use their own carrier, please get the SIM kit from your own carrier. Make sure to add a regular phone line with talk, text and data for your TickTalk 4. The TickTalk 4 is not compatible with any wearable, digits or tablet plans. TickTalk 4 Frequency Bands 4G B2/ 1900 B4/ 1700 B5/ 850 B7/ 2600 B12/700 B17/740 ACTIVATE THE SIM Step 1 Go www.redpocket.com/activate or www.myticktalk.com and click Activate in the menu bar. Step 2 Input your SIM ICCID # and follow Red Pocket’s Activation Steps to activate your SIM and create your account. Step 3 Before you choose your monthly plan, it will ask you “Do you have an Activation PIN#?”, please choose NO. Step 4 Choose your monthly plan. We recommend the two plans below for the TickTalk 4, the monthly plan has no contract, you can switch to a different plan based on your usage anytime. Activate Red Pocket’s SIM card $10/30 days with 500 minutes, 500 texts and 500MB of data $15/30 days with 1000 minutes, unlimited texts and 1G of data INSERT THE SIM Slide from the side to insert the SIM card into the slot of the CARD COVER. Make sure the back cover is COMPLETELY snapped back on to secure the waterproof protection. Turn the TickTalk 4 on after the SIM is installed. If the SIM CAN’T BE READ, please RE-INSTALL the SIM again. 1. Bad cellular reception. 2. Slow network connection. 3. Invalid or inactive SIM or wrong plan. 4. TickTalk server connection issue. NETWORK CONNECTIVITY Make sure your TickTalk 4 has successfully connected to the network. It’ll show the CONNECTED ICON on the top middle of the watch screen. Otherwise, the watch won’t work. Why don’t I see the CONNECTED ICON? 1. Check the carrier’s coverage map in your location. If you have bad coverage indoors, please connect to Wi-Fi. 2. Check if your SIM card is activated and you must have credit in your account. Check if you have the regular phone plan with talk, text and data instead of WEARABLE or DIGITS PLANS. 3. Contact the TickTalk Technical Support Team. How do I SOLVE this issue? DOWNLOAD THE APP TickTalk 1TickTalk 2 TickTalk 3 Download on the App Store Get the APP for Android Please search TICKTALK 4 in APP STORE or GOOGLE PLAY if you’re not able to locate the APP simply scan the QR codes above. SIGN UP Sign up in the App with your name, email and phone number. For SAFETY REASONS, the first person who pairs the watch to the App will be the PRIMARY USER. Only the PRIMARY USER will have the capability to manage and approve any SECONDARY USERS to use the App to connect to their TickTalk 4. PAIR TO TICKTALK 4 Go to watch settings, click PAIR ME, it’ll show the QR code. From the App, click pair your TickTalk 4. Use your cell phone to scan the QR code on the watch screen. Make sure the WATCH IS ON and CONNECTED to the mobile NETWORK before your pair it. EDIT WATCH USER’S INFO Click the ARROW ICON on the top right corner to edit your child’s personal info. You cannot call your TickTalk 4 until the watch’s phone number and child’s personal info has been all set up in the App. Click the ARROW ICON on top right of the screen to add another TickTalk 4 to the App. Once you add multiple watches in the App, you can SWITCH TO DIFFERENT WATCHES by clicking the watch’s name. PRESET CONTACTS Click the CONTACTS ICON on the bottom left in the App. You can add up to 53 contacts. These contacts should be trusted and pre-authorized persons who can CALL YOUR CHILD and YOUR CHILD CAN CALL. TROUBLE SHOOTINGS Watch Overheating The TickTalk 4 works basically the same as our personal smart phone, however, with the smaller size of the watch, our engineering team could not avoid the watch from overheating after extended use.We have taken extreme precautions by using heat insulation parts in the watch. Under normal circumstances, the maximum temperature will be 104 degrees Fahrenheit. Once you stop using the watch the temperature will drop very quickly. 1. The 4G version will consume much more power than the 2G version, If you enter a spot where the reception is not good, the CPU will keep searching for the signal which will generate heat. 2. Video calls re…
