Operating Instructions
Operating the Tentacle Sync E MKII involves initiating and maintaining timecode synchronization:
- Power On: Press and hold the power button (if applicable, or refer to the specific device's power-on method) to turn on the Tentacle Sync E MKII.
- Master/Slave Configuration: Designate one Tentacle Sync E MKII unit as the master and the others as slaves. The master unit generates the timecode, which is then transmitted to the slave units.
- Initiate Sync: Using the Tentacle Sync app on your smartphone or tablet, initiate the synchronization process. The app will detect available Tentacle devices via Bluetooth and allow you to set the timecode. Alternatively, if using an external master, connect the master's timecode output to the Sync E's input.
- Verify Sync: Once synchronized, the status LEDs on the Sync E units will indicate successful timecode lock. Verify the timecode on your connected cameras and audio recorders to ensure they are receiving the correct timecode signal.

- Battery Life: The Tentacle Sync E MKII offers approximately 35 hours of battery life on a full charge, allowing for extended use during production.
Maintenance
Proper maintenance ensures the longevity and reliable performance of your Tentacle Sync E MKII devices:
- Cleaning: Use a soft, dry cloth to clean the exterior of the devices. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the devices in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery health, avoid fully discharging the batteries frequently. Recharge them regularly, especially if storing the devices for extended periods.
- Firmware Updates: Periodically check the manufacturer's website for firmware updates to ensure your devices have the latest features and performance enhancements.
Troubleshooting
If you encounter issues with your Tentacle Sync E MKII, consider the following:
- No Timecode Lock: Ensure all devices are powered on and within Bluetooth range. Verify that the master unit is correctly configured and transmitting timecode. Check cable connections to cameras/recorders.
- App Connectivity Issues: Confirm Bluetooth is enabled on your mobile device. Restart the Tentacle Sync app and the Sync E units. Ensure the app is updated to the latest version.
- Short Battery Life: Ensure devices are fully charged before use. Battery performance can degrade over time; if significantly reduced, contact support.
- Inaccurate Timecode: Re-sync all devices from the master. Ensure no external interference is affecting the signal.
