• Integrated Adjuster: Allows for magnetic declination adjustment, crucial for accurate readings in different geographical locations.
• Kanta Pembesar: Aids in reading fine details on maps.
• Kaki Getah: Provides stability for precision map work, preventing slippage.
• Ciri-ciri bercahaya: Graduation ring and markings glow in the dark for up to 4 hours after activation by daylight or flashlight, enabling night navigation.
• Scale Lanyard & Slope Card: Included for quick distance judgment and route planning.
• Mirror Sighting System: For precise bearing taking.

3. Persediaan

1. Pasang Lanyard: Secure the included scale lanyard to the compass. This helps prevent loss and provides a convenient way to carry the compass.
2. Biasakan diri: Open the compass fully. Identify the main compass dial, the sighting mirror, the sighting notch, and the various scales on the baseplate.
3. Check Luminous Markings: Expose the compass to bright light (daylight or flashlight) for a few minutes to charge the luminous markings for potential night use.

4. Arahan Operasi

4.1 Basic Orientation

1. Hold the compass flat and steady in your hand, ensuring it is level.
2. Allow the magnetic needle to settle. The red end of the needle points to magnetic North.
3. Rotate the compass housing until the red end of the needle aligns with the 'N' (North) on the dial. You are now oriented to magnetic North.

4.2 Taking a Bearing (Mirror Sighting)

1. Open the mirror lid to an angle of approximately 45 degrees.
2. Hold the compass at eye level, looking through the sighting notch in the mirror lid.
3. Align the sighting line in the mirror with your target object.
4. Simultaneously, observe the compass dial in the mirror reflection. Rotate the compass housing until the red end of the magnetic needle aligns with the 'N' (North) on the dial.
5. The reading at the index line (the line directly under the sighting notch) is your bearing to the target.

4.3 Declination Adjustment

Magnetic declination is the angle between magnetic North (where your compass points) and true North (geographical North). This angle varies depending on your location. The Silva 16DCL features an integrated adjuster for declination.

1. Determine the local magnetic declination for your area (often found on topographical maps or online resources).
2. Use a small tool (e.g., the included lanyard key or a small screwdriver) to rotate the declination adjustment screw on the compass housing.
3. Adjust the declination scale to match your local declination value. This will offset the 'N' on the dial, allowing you to read true North directly.

4.4 Map Work (Scales & Magnifying Lens)

• Jarak pengukur: Use the millimeter (mm) and inch scales on the baseplate to measure distances on your map. Refer to the map's scale (e.g., 1:25,000, 1:50,000) to convert map distance to real-world distance.
• UTM Scales: The compass includes UTM position plotting scales (1:25k, 1:50k) for precise coordinate identification on UTM grid maps.
• Kanta Pembesar: Utilize the integrated magnifying lens to examine small details, contour lines, or text on your map.

4.5 Night Navigation

The luminous graduation ring and markings allow for navigation in low-light conditions.

1. Before night use, expose the compass to a strong light source (e.g., flashlight, sunlight) for at least 30 seconds to activate the luminescence. The markings will glow for up to 4 hours.
2. In the dark, align the glowing 'N' with the magnetic needle to find North, and use the glowing markings to take bearings.

4.6 Slope Card Use

The included slope card assists in quickly estimating distances and planning routes based on terrain slope.

1. Refer to the slope card to understand how different slope angles affect perceived distance and travel time.
2. Use the clinometer feature (if available on your specific model, or estimate visually) to determine the slope of the terrain.
3. Apply the information from the slope card to adjust your route planning and distance estimations.

5. Penyelenggaraan

• Pembersihan: Clean the compass with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the acrylic or markings.
• Storan: Store the compass in a cool, dry place away from strong magnetic fields (e.g., magnets, electronic devices) to prevent demagnetization of the needle.
• Pemeriksaan: Periodically check the compass for any signs of damage, such as cracks in the baseplate or mirror, or a sticky needle.

6. Penyelesaian masalah

• Jarum Tidak Mendap: Ensure you are holding the compass level and away from any magnetic interference (e.g., metal objects, power lines, electronic devices).
• Bacaan Tidak Tepat: Verify that the magnetic declination is correctly set for your current location.
• Faint Luminous Markings: Recharge the luminous markings by exposing them to a strong light source.
