4. Configuração e montagem
4.1. Montagem
- Conecte a bobina de busca: Secure the DD searchcoil to the lower stem using the provided bolt and washers. Ensure it is firmly attached but can still pivot.
- Connect the Stem Sections: Extend the adjustable stem sections and lock them into place. The ATX Extreme is fully collapsible, allowing you to adjust the length to your preference.
- Monte a caixa de controle: Slide the control housing onto the upper stem. Adjust the armrest for comfortable use.
- Connect Searchcoil Cable: Carefully wrap the searchcoil cable around the stem, ensuring it is not too tight or loose, and plug it into the designated port on the control housing. Tighten the connector securely.
4.2. Instalação da bateria
The ATX Extreme requires batteries for operation. Ensure they are fully charged before first use.
- Localize o compartimento da bateria na caixa de controle.
- Abra a tampa do compartimento.
- Insert the rechargeable batteries according to the polarity indicators (+/-).
- Close the battery compartment cover securely to maintain its waterproof seal.
- To charge the batteries, connect the provided charger to the charging port on the control housing and plug it into a power source.
5. Instruções de operação
5.1. Ligar/desligar
To power on the detector, press and hold the Power button until the unit activates. To power off, press and hold the Power button again until the unit shuts down.
5.2. Equilíbrio do solo
The Advanced Ground Balance feature allows the ATX Extreme to operate efficiently in various ground conditions. Perform ground balance by pumping the searchcoil up and down over the ground while pressing the Ground Balance button. The detector will automatically adjust to the mineralization levels.
5.3. Modos de Detecção
The ATX Extreme offers both Motion and Non-Motion modes:
- Modo de movimento: Requires the searchcoil to be in motion to detect targets. This mode is generally used for wider area scanning.
- Non-Motion Mode: Allows for detection of targets even when the searchcoil is stationary. Useful for pinpointing targets or searching in confined spaces.
Refer to the control panel for specific button functions to switch between modes.
5.4. Ground Track
Select one of the 4 Ground Track settings to best suit the current ground conditions. This feature continuously monitors and adjusts to changing ground mineralization, maintaining optimal performance.
5.5. Varredura de Frequência
If you experience interference from other electronic devices, use the automatic Frequency Scan function. This will help minimize RFI and provide a clearer signal.
5.6. Controle de volume
Adjust the volume to your preference. Reducing the volume can help in distinguishing deep or faint signals by limiting the overwhelming response from large, shallow targets.
5.7. Quick Iron Check and Discrimination
Utilize the Quick Iron Check feature to rapidly identify potential iron targets. The adjustable Discrimination setting allows you to filter out unwanted metallic junk, focusing on more valuable targets.
6. Cuidados e Manutenção
- Limpeza: After each use, especially in saltwater or muddy conditions, clean the detector with fresh water and a soft cloth. Ensure all connections are dry before storage. Do not use abrasive cleaners.
- Armazenar: Store the detector in a cool, dry place. If storing for an extended period, remove the batteries.
- Cuidados com a bateria: Always use the recommended charger for the rechargeable batteries. Avoid overcharging or completely draining the batteries to prolong their lifespan.
- Gerenciamento de cabos: Ensure the searchcoil cable is not kinked or damaged. Inspect it regularly for wear.
- Selos à prova d'água: Periodically check the integrity of all waterproof seals, especially around the battery compartment and cable connections, to maintain the IP68 rating.
7. Solução De Problemas
7.1. Sem energia
- Verifique se as baterias estão instaladas corretamente e totalmente carregadas.
- Certifique-se de que a tampa do compartimento da bateria esteja bem fechada.
7.2. Erratic Signals / False Signals
- Perform a Ground Balance procedure.
- Use the Frequency Scan function to minimize RFI.
- Ensure the searchcoil cable is securely connected and not damaged.
- Check for nearby sources of electromagnetic interference (power lines, other electronics).
7.3. Poor Detection Depth
- Ensure proper Ground Balance has been achieved for the current soil conditions.
- Check battery charge level; low batteries can affect performance.
- Verify that the searchcoil is clean and free of debris.
