4. Setup
- Unpacking: Carefully remove the compass and all accessories from the packaging.
- Lanyard Attachment: Attach the included lanyard to the designated loop on the compass for secure carrying.
- Initial Inspection: Check the compass for any visible damage. Ensure the dial rotates freely and the fluid capsule is clear.
5. Operating Instructions
5.1 Basic Compass Use
- Holding the Compass: Hold the compass level and steady, away from any magnetic objects (e.g., phones, metal tools).
- Orienting the Compass: Allow the magnetic needle to settle. The red end of the needle typically points North. Rotate the compass body until the 'N' on the dial aligns with the North-pointing needle.
- Reading Bearings: Once oriented, the degree markings on the dial indicate the direction relative to North.
5.2 Sighting Optic Operation
The sighting optic allows for precise bearing acquisition:
- Open the compass fully.
- Look through the sighting window and align the sighting line with your target.
- Simultaneously, observe the internal compass card through the prism lens. The vertical lubber line will indicate the precise bearing to your target.
5.3 Clinometer Function
The clinometer measures angles of inclination or declination:
- Hold the compass on its side, aligning the base with the slope or object you wish to measure.
- Read the angle indicated by the clinometer needle on the dedicated scale.
Figure 5.1: Demonstrates how to use the clinometer to measure an angle, showing a reading of 30.5 degrees.
5.4 Fluorescent Scale Use
For use in low-light conditions, expose the compass to a light source (e.g., sunlight, flashlight) for a few minutes. The luminous markings on the magnet arrow and compass card will glow, allowing for visibility in the dark.
5.5 Plotting and Centimeter Scales
The compass features graduated scales along its edges for map work:
- Centimeter Scale: Use for direct measurements in centimeters.
- Plotting Scale: Designed for measuring distances on maps with specific scales (e.g., 1:25000).

6. Maintenance
- Cleaning: Wipe the compass with a soft, dry cloth to remove dust and dirt. For stubborn marks, use a slightly damp cloth and dry thoroughly. Avoid abrasive cleaners or solvents.
- Storage: Store the compass in its protective carry bag when not in use. Keep it in a cool, dry place, away from direct sunlight and strong magnetic fields.
- Avoid Impacts: While durable, avoid dropping or subjecting the compass to severe impacts, which could affect its calibration and functionality.
7. Troubleshooting
7.1 Compass Pointer Disturbance
If the compass pointer appears erratic or does not settle correctly, it is likely being affected by a magnetic field.
- Solution: Move away from any potential sources of magnetic interference, such as electronic devices (mobile phones, GPS units), large metal objects, power lines, or magnetic rocks. The compass should be used in an area free from such disturbances for accurate readings.

9. Safety Information
To ensure accurate readings and proper functioning of your compass, observe the following safety guidelines:
- Magnetic Fields: Keep the compass away from strong magnetic fields. Proximity to electronic devices, large metal objects, or certain types of rocks can disturb the magnetic needle and lead to inaccurate readings.
- Temperature Extremes: While designed for a wide temperature range, avoid prolonged exposure to extreme heat or cold beyond the specified operating temperatures to prevent damage to the fluid or internal components.
- Water Exposure: The compass is IP65 rated for water resistance, meaning it can withstand rain and splashes. However, it is not designed to be submerged in water. Avoid prolonged immersion.
