VGC VR-N7600 (01) PDF Document

To ensure the long life of the VGC VR-N7600 components, please follow these installation tips:

Ventilation: Provide adequate ventilation around the cabinet of the transceiver. Do not install the transceiver on top of another heat-generating device (such as a power supply or amplifier).

Environment: Do not install in a location exposed to dust and/or high humidity. Avoid heating vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates. This transceiver should not be used in an environment where the ambient temperature exceeds +140 °F (+60 °C).

Please observe the following power requirements:

• This transceiver is designed for a 13.8 V power source. Never use a 24 V battery to power the transceiver.
• The vehicle battery must have a nominal rating of 12 V. Never connect the transceiver to a 24 V battery.
• Be sure to use a 12 V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmit output power may drop excessively.

Different shortcut operations can be realized through programming [P1] / [P2] / [P3] / [P4] keys. This can only be operated through the APP.

Method 1: Automatic Pairing

1. Open the installed APP.
2. From the VGC VR-N7600 main menu, select [Pairing], OR double click [P0] to enter Pairing mode.
3. When the message “Detected new device VR-N7600, do you want to link now?” appears in the app, click [Yes].
4. The APP will begin connecting to the radio.
5. A Bluetooth authorization dialog box will pop up. Click [Pair] to confirm. Once connected successfully, the device will be ready for use.

Method 2: Manual Binding

1. Click “Bind new device” in the APP.
2. Ensure the radio is in Pairing Status (LED flashing).
3. A device selection menu will appear (e.g., walkie-talkie, wireless PTT). Choose the target device.
4. After confirmation, the system will prompt you to enable Bluetooth and click [Allow] to pair.

Troubleshooting (No Pairing Prompt?): If the [Allow] prompt does not appear, swipe down from the top of your phone screen to open the notification bar. Locate the pending Bluetooth pairing request and manually select [Allow].

Power On: While the radio is off, press and hold the microphone P0 key for 3 seconds until the screen displays the device model with a startup tone, indicating successful activation.

Power Off: While the radio is operational, press and hold the microphone P0 key for 3 seconds until the screen displays “Power Off” and the device shuts down.

In standby mode, short press the Standby button (the rectangular button above the arrows) to cycle through the following three display interfaces:

1. First Interface: User Information Display. Shows owner registration details and device status.
2. Second Interface: Communication Log Display. Displays recent callers’ locations and real-time distance.
3. Third Interface: Message Notification Display. Shows the 30 most recently received text messages with location data. (Note: This interface stores temporary data, which is automatically cleared after power-off).

In any secondary screen interface, press the Standby button to directly return to the standby screen. Continuous presses will loop through all available display modes.

When the “=” Sensor Prompt Icon appears:

1. Enter the [Compass] menu.
2. Place the device horizontally (screen facing up).
3. Press the [OK] key in the upper-left corner of the keypad to confirm. (Note: Keep away from magnetic interference sources during calibration).

When the “∞” Sensor Prompt Icon appears:

1. Enter the [Compass] menu.
2. Follow the on-screen prompt: “Rotate the device in an ∞-shaped pattern for sensor calibration”.
3. Hold the microphone straight forward.
4. Quickly and firmly trace an ∞-shaped pattern.
5. Recommended: Complete 1-8 full motions within ~2 seconds.

Special Conditions: If the compass responds sluggishly during use, immediately enter the [Compass Calibration] menu for sensor recalibration.

In standby mode, press and hold the P1 key (programmable) to toggle between Main/Sub channels. The currently active channel (primary channel) is displayed in large font on the screen.

3. Sync Completion: When the frequency stops flashing, the screen locks onto the detected frequency and simultaneously displays matched tone parameters.
4. Save Settings: You have the option to save scan results to any designated channel. Press [Confirm] to complete storage.

Note: Keep the transmitter at an appropriate distance during synchronization. Close proximity may cause frequency measurement inaccuracies.

1. Receiver Setup: Power on all target radios sequentially. Set menu to [Receive channel] mode.

3. Programming Process: Automatic data transmission initiates. Each radio displays “Complete” when its frequency list is successfully copied.
4. Completion Indicators: All target radios show completion status. Copied frequency lists fully overwrite existing configurations.

Important Notes: Ensure all devices are within effective communication range. Do not power off any device during the copying process. It is recommended to perform this in environments with minimal electromagnetic interference.

1. Connect Device: Open HT App and connect your radio.
2. Export Frequency Table: Go to “Channel & Group Management” -> Tap [Import] -> Select [Import from Device]. Name the new group and save. When prompted “Sync to Device?”, choose No.
3. CSV File Editing: Export the CSV file to a computer, edit, and save it back to your phone. Tap [Import] -> Select [File] -> Browse and choose the edited file. Save to the target group.
4. Sync to Device: Locate the new group in the channel list and tap the upload icon to sync it to the corresponding device group.

Activate Radio: Navigate to [Radio] in the menu. The FM radio automatically powers on.

Frequency Scan: Press [Up/Down Arrow] to auto-scan for available stations. Auto-lock & play occurs when a valid frequency is detected.

Deactivate Radio: Select [Radio] in the menu and Tap “Power Off” to disable.

3. Enable APRS: Navigate to Digital Mode Menu -> Select “Enable”. Choose “APRS” in the format options.
4. Location Sharing Settings: Set transmission interval (e.g., every 10 min) or select “Off” to disable auto-broadcasting.
5. Channel Configuration: Assign a dedicated channel for APRS data transmission.

Smart Beacon Mode automatically extends the location sharing interval configured in Share Location based on movement. When enabled, the maximum sharing interval is 30 minutes, while the minimum interval remains the duration set in Share Location.

Location Reporting Triggers: A location report will be sent if any of the following conditions are met:

• Heading change exceeds 30°
• Speed variation exceeds 30 km/h and persists for 120 seconds
• Time elapsed since last report exceeds 30 minutes

Note: The time since the last report must be greater than the Share Location interval for a report to be sent.

When enabled, AI-powered noise reduction activates during both transmission (speaking) and reception (listening).

• Transmit AI Noise Reduction: Uses smart noise separation and dynamic noise suppression. Includes wind noise optimization for clearer outgoing audio.
• Receive AI Noise Reduction: Uses intelligent noise filtering, voice enhancement, and adaptive noise cancellation for cleaner incoming audio.

Important Note: Turn off AI noise reduction in weak signal conditions. Extremely fragmented signals may be misclassified as noise, resulting in full audio cutoff.

PTT Follow Mode enables auto-transmission on the active receive Band (A/B) via PTT (when pressed within 3 seconds after reception ends) without manual switching.

Operation Guide:

1. Activation: Enable [PTT Follow] in the menu.
2. Transmission Logic:
   • Main Band (A) Active: PTT transmits on Band A.
   • Sub Band (B) Active: PTT auto-switches to Band B.
