• 【MIC Gain】 To adjust the MIC receiving sensibility. The higher the value, the more sensibility the MIC.
• 【SPK Gain】 To adjust the speaker's volume. The higher the value, the louder the speaker. To avoid audio distortion, please don't turn up the speaker highly.
• 【Adjacent Channel Limiting】 When listening to the signals from some machines with excessive frequency offset, the communication may be intermittent. In such cases, you can increase the adjacent channel suppression threshold level.
• 【DTMF Delay】 If DTMF tone is needed, it will be sent out at appointed time.
• 【DTMF Interval】 To set up the interval of two DTMF codes.
• 【DTMF Duration】 To set up the lasting time of individual DTMF code.

• 【Refresh Time for Transmitting Sound Pressure】 Changes the refresh time interval of the sound pressure bar when transmitting.
• 【Refresh Time for Receiving Field Strength】 Changes the refresh time interval of the field strength table. When receiving weak signals, if the refresh speed of the field strength table is too fast, it may introduce interference sounds. In such cases, you can appropriately increase the refresh time interval of the field strength.
• 【Temporary Debugging】 If you want to adjust the receiving sensitivity, enable "Temporary Receiving Threshold Activation" and then set the "Temporary RSSI Threshold" and "Temporary Noise Threshold". A higher RSSI value makes receiving and activation harder, while a higher Noise value makes it easier.

If you need to adjust the transmission power, please enable the [Temporary Power Unlock], and then adjust the power tuning values for different frequency bands. When the tuning value exceeds a certain threshold (which varies for each device), further increasing it may only raise the current without boosting the power, and it can easily damage components such as the power transistor. Therefore, it is not advisable to adjust it too much.

Note: Users who are not familiar with the technical specifications of the walkie-talkie should not use the temporary adjustment function, as it may cause damage to the components.
