Брз почеток
This is a brief introduction to using your device. Full documentation and instructions are available online at https://cooltech.zone/tangara/.
1. Prepare an SD card with music in an appropriate format. Tangara supports all FAT filesystems, and can play music in WAV, MP3, Vorbis, FLAC, and Opus formats.
2. Install your SD card into the cover as shown, then insert the card into the device.
3. Turn the device on using the lock switch. You should see the Tangara logo appear as a splash screen, shortly followed by a menu.
4. Move your thumb or finger clockwise around the touchwheel to scroll forwards in the menu, or anticlockwise to scroll backwards. Tap the centre of the touchwheel to select the highlighted item. Alternative control schemes can be selected through the on-device settings.
5. Tangara will automatically index music on your SD card into its database, allowing you to browse your music by Album, Artist, Genre, or directly by File. Selecting a track from the device’s browser begins playback.
6. When music is playing, the lock switch will turn off the display and disable controls, without interrupting playback. When music is not playing, the lock switch can be used to place the device into a low-power standby mode.
Bluetooth
Tangara supports streaming audio to Bluetooth audio devices, such as portable speakers. To play music to a Bluetooth device, do the following:
1. Turn on your Tangara, and navigate to the Settings page, then to the Bluetooth option.
2. Enable Bluetooth using the displayed ‘Enable’ settings toggle, then navigate to the ‘Pair new device’ screen.
3. Turn on your Bluetooth audio receiver (e.g. your speaker).
4. Wait for your Bluetooth audio receiver to be displayed within the ‘Nearby Devices’ list. This may require some patience.
5. Select your device, and wait for Tangara to connect to it.
6. Once you have connected, any music selected on Tangara will be played back using the connected device instead of Tangara’s headphone output.
If your Bluetooth device does not appear on the list of nearby devices, then try turning its pairing mode off and on again. The product manual for your Bluetooth device may contain additional device-specific troubleshooting steps.
Расклопување
Внимание: These instructions are provided for hobbyists to tinker and make their own repairs and modifications. The manufacturer cannot be held liable for damage or injury if you choose to service your device yourself.
1. Starting with the front of the device, unscrew and remove the top-right and bottom-left screws securing the front of the case.
2. Flip the device over, and unscrew the top-right and bottom-left screws securing the back of the case.
3. The two case halves should now come apart, using only a very gentle amount of force. Holding them apart slightly, carefully remove the button and switch covers.
4. Flip the device back over to the front side, and carefully lift up the left side of the front half. Avoid using too much force, as you do not want to strain the ribbon cable connecting the two halves.
5. Disconnect the faceplate ribbon cable from the mainboard by flipping the latch on the connector up and gently pulling the cable out. Once you have disconnected this cable, the two halves of the device will come apart freely.
6. Unplug the battery by gently pulling on the battery connector whilst twisting it back and forth. Avoid tugging on the battery cable directly.
7. Unscrew the two remaining front-half standoffs to remove the faceplate and touchwheel cover.
8. Unscrew the two remaining back-half standoffs to remove the battery cage and battery.
To reassemble your device, follow the above steps in reverse; start by assembling the front and back halves with two standoffs securing each, and then screw both halves of the device together. When reassembling, take great care to avoid over-tightening any screws, or you may risk fracturing the polycarbonate case.

ЗАБЕЛЕШКА: Оваа опрема е тестирана и утврдено е дека е во согласност со ограничувањата за дигитален уред од класа Б, во согласност со дел 15 од Правилата на FCC.
Овие ограничувања се дизајнирани да обезбедат разумна заштита од штетни пречки во станбена инсталација. Оваа опрема генерира, користи и може да зрачи енергија на радиофреквенција, а доколку не се инсталира и користи во согласност со упатствата, може да предизвика штетни пречки во радио комуникациите. Сепак, не постои гаранција дека нема да има пречки во одредена инсталација. Доколку оваа опрема предизвика штетни пречки на радио или телевизиски прием, што може да се утврди со исклучување и вклучување на опремата, корисникот се охрабрува да се обиде да ги поправи пречките со една или повеќе од следниве мерки:
- Преориентирајте ја или преместете ја приемната антена.
- Зголемете го одвојувањето помеѓу опремата и приемникот
- Поврзете ја опремата во штекер на коло различно од она на кое е поврзан ресиверот.
- Консултирајте се со продавачот или со искусен радио/телевизиски техничар за помош.
