Yes, it can be replaced.

Number of Channels:
Currently, it supports only one channel.

Connection Quantity Recommendation:
Theoretically, there is no limit on the number of connections. However, to maintain orderly operation, it is recommended not to connect more than 5 Underwater Transceiver-Mini units simultaneously.

1. Avoid excessive tilting of your head underwater:
The Mouthpiece Microphone is positively buoyant, and tilting your head up may cause it to press against the mask skirt, leading to leaks. It’s recommended to keep your head level and move slowly when adjusting your head position.
2. Choose a low-volume mask to pair with the Mouthpiece Microphone:
It’s advisable to select a low-volume mask for use with the Mouthpiece Microphone to minimize the risk of interference and leaks.

Tooth Hook Adaptation Advice:
As a new structure, the Tooth Hook might initially cause a foreign object sensation in the mouth. However, with increased use, your mouth will gradually adapt, and the discomfort will diminish. To help with this, try relaxing your jaw and practice finding a position where the Tooth Hook doesn’t press against your gums but also stays securely in place.

Cable Management Advice:
You can use the Velcro strap included in the package for cable management. For detailed steps, please refer to the [Quick Start Video](link to video).

1. Check the width of the mask strap:
Ensure that the mask strap is no wider than 2 centimeters. A wider strap may cause the Underwater Receiver to be unstable.
2. Adjust the positioning of the Underwater Receiver:
Adjust the mask strap and Underwater Receiver to the recommended position. For detailed steps, please refer to the [Quick Start Video](link to video).

1. Remove water droplets from the microphone:
Ask your dive buddy to press the second-stage regulator to clear any water droplets from the microphone inside the Mouthpiece Microphone. This may improve audio quality.
2. Check environmental factors:
Determine if the static noise is due to complex terrain, significant obstructions, or excessive distance between users. Try communicating face-to-face to see if the issue persists.
3. Eliminate noise interference:
Check for noise sources such as boat engines on the surface or swimming pool circulation systems that might be causing interference.
4. Technical Support:
If the issue is still unresolved, please contact our technical support team (FAE) at support@divintok.com for assistance.

1. Check the connection:
Ensure that the Mouthpiece Microphone is securely connected to the second stage regulator, using a zip tie to guarantee stability.

2. Adjust the fit:
Check whether the Mouthpiece Microphone is tilting up or down and adjust it to fit snugly against your face. For detailed steps, please refer to the [Quick Start Video](link to video).

3. Seek technical support:
If the issue persists, please contact our technical support team (FAE) at support@divintok.com for assistance.
