- Using with a camera
For BOYA mini-19 package
This package comes with 3 kinds of receivers, namely the Lightning, USB-C and 3.5 mm TRS receiver, allowing you have more choices whether you want to output audio to a phone or a camera. If you are going to use the Lightning or USB-C receiver to output audio to a phone, please refer to the above instructions from "For BOYA mini-12 package to BOYA mini-17 package". If you are going to use the 3.5 TRSreceiver to output audio to a camera, please refer to the above instructions from "For BOYA mini-18 package".
Tips:
- It is recommended to record a sample and play it back to check if the audio level is acceptable before recording.
- In order to improve the recording effect in a noisy environment, it is recommended to press the power button on the transmitter(s) to enable noise reduction (this function on both transmitters will be enabled or disabled at the same time). You can also operate the receiver to select an optimal noise reduction grade.
- Put the unit back into the charging case for charging after recording.
Troubleshooting
Note:
Due to the 2.4 GHz wireless frequency, signals can be easily attenuated. Please try to avoid obstacles, such as walls and buildings, and avoid close proximity to devices with 2.4 GHz signals, such as high-power Wi-Fi antennas, radios, etc.
If you encounter problems when using the unit, please refer to the following checklist first. If the problem cannot be solved, please contact the dealer's after-sales service department.
- If there is no sound from the unit or no sound when connected to an external device
Make sure the connector on the receiver is well connected to your device. - The operating range of the unit is limited and the sound is frequently intermittent
Make sure there is no interference between the transmitter(s) and receiver. If the intermittent sound still occurs frequently, please contact customer service. - The charging case fails to charge the unit
1 Make sure charging contacts are in full contact. Wipe charging contacts with a clean cloth and try again.
2 If you want to check whether the magnetic force is aging or whether charging contacts are not in sufficient contact, push down the unit placed in the charging case until charging contacts are in full contact to see if it is charged. If the unit still fails to be charged, please contact customer service.
