• തിരച്ചിൽ കോയിൽ: The primary detection component, which is waterproof.
• നിയന്ത്രണ യൂണിറ്റ്: ഇലക്ട്രോണിക്സ്, ഡിസ്പ്ലേ, നിയന്ത്രണങ്ങൾ എന്നിവ ഇവിടെയുണ്ട്.

4. സജ്ജീകരണവും അസംബ്ലിയും

Follow these steps to assemble your GT620G Metal Detector:

1. സെർച്ച് കോയിൽ അറ്റാച്ചുചെയ്യുക: Connect the search coil to the lower stem using the provided hardware (knob and washers). Ensure it is securely fastened but allows for slight angular adjustment.
2. തണ്ട് കൂട്ടിച്ചേർക്കുക: Connect the lower stem to the upper stem. The stem is adjustable in length.
3. Attach the Control Unit and Armrest: Slide the control unit onto the upper stem. Attach the armrest to the upper stem. Secure all connections.
4. ബാറ്ററികൾ ചേർക്കുക: The detector requires two 9V alkaline batteries (not included). Open the battery compartment on the control unit (refer to Figure 4) and insert the batteries, observing correct polarity. Close the compartment securely.
5. നീളം ക്രമീകരിക്കുക: Adjust the stem length using the stem lock nut to a comfortable position that allows the search coil to be parallel to the ground when sweeping. The detector's height is adjustable from approximately 22.5cm to 112cm (8.85in to 44.09in).

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The GT620G offers two primary detection modes:

• എല്ലാ മെറ്റൽ മോഡും: Detects all types of metal objects. This mode is ideal for general searching when you want to find any metallic item.
• DISC (വിവേചന) മോഡ്: Allows the detector to distinguish between different types of metals, enabling you to filter out unwanted metals (e.g., iron trash) and focus on more valuable targets. Use the knob to adjust the discrimination level.

അടിസ്ഥാന പ്രവർത്തനം:

1. പവർ ഓൺ: Turn on the detector using the power button on the control unit.
2. മോഡ് തിരഞ്ഞെടുക്കുക: Choose between ALL METAL and DISC modes based on your search preference.
3. സംവേദനക്ഷമത ക്രമീകരിക്കുക: Use the control knob to adjust the detector's sensitivity. Higher sensitivity can detect smaller or deeper objects but may also increase false signals in mineralized ground.
4. കോയിൽ തൂത്തുവാരുക: Hold the detector with the search coil parallel to the ground, about 1-2 inches above the surface. Sweep the coil slowly from side to side in overlapping motions.
5. Signal Indication: When a metal object is detected, the LCD screen will display an indication, and an audible tone will sound (if not using headphones).
6. ചൂണ്ടിക്കാണിക്കുന്നു: Once a target is detected, press the Pinpoint button to narrow down the exact location of the object. Move the coil slowly over the target area until the strongest signal is heard/displayed.
7. Earphone Use: For private searching or in noisy environments, connect headphones (not supplied) to the earphone jack on the control unit.

6. പരിപാലനം

• വൃത്തിയാക്കൽ: ഓരോ ഉപയോഗത്തിനു ശേഷവും, പരസ്യം ഉപയോഗിച്ച് ഡിറ്റക്ടർ തുടച്ചുമാറ്റുക.amp cloth. For the search coil, especially after use in water or dirt, rinse it with fresh water and dry thoroughly. Do NOT submerge the control unit in water.
• ബാറ്ററി കെയർ: Always remove the batteries if the detector will not be used for an extended period to prevent leakage and damage.
• സംഭരണം: Store the detector in a cool, dry place. Avoid extreme temperatures and direct sunlight.
• കേബിൾ മാനേജുമെന്റ്: Ensure all cables are not pinched or excessively bent, as this can lead to damage and signal issues.

7. പ്രശ്‌നപരിഹാരം

• ശക്തിയില്ല: Check if the batteries are inserted correctly with the right polarity. Ensure batteries are fresh and fully charged.
• Erratic Signals/False Alarms: This can be caused by high sensitivity in mineralized ground, electromagnetic interference from power lines or other electronics, or nearby metallic objects. Try lowering the sensitivity or moving to a different location.
• കണ്ടെത്തൽ ഇല്ല: Ensure the detector is turned on and the search coil is properly connected. Check battery levels.
• Poor Depth Detection: Ensure sensitivity is set appropriately for the ground conditions. Large, highly conductive objects are typically detected at greater depths than small, less conductive ones.

• കണ്ടെത്തൽ ആഴം: The depth of detection can vary significantly based on the size, material, and age of the buried object, as well as the mineralization of the soil. Larger, more conductive objects buried in less mineralized soil will generally be detected deeper.
• പരിശീലനം പൂർണതയിലെത്തിക്കുന്നു: Spend time in a known area (e.g., your backyard) with various buried metal objects to get a feel for the detector's responses and how to interpret signals.
• ഹെഡ്ഫോണുകൾ: Using headphones can help you hear subtle signals that might be missed in noisy environments, improving your detection accuracy.
• Slow Sweeps: Always sweep the search coil slowly and deliberately. Rushing can cause you to miss targets.
