4. Setup
The Proster TL150 compass requires minimal setup before use.
- Unpack: Remove the compass and all accessories from the packaging.
- Attach Lanyard: Secure the lanyard to the compass for easy carrying and to prevent loss.
- Open Cover: Fold open the metal cover to reveal the compass dial and sighting optic.
- Check Bubble Level: Ensure the compass is held horizontally by observing the bubble level (gradienter). The bubble should be centered for accurate readings.
5. Operating Instructions
5.1 Basic Compass Use
To take a basic bearing:
- Hold the compass level and steady.
- Allow the magnetic needle to settle. The red end of the needle points to Magnetic North.
- Rotate the compass housing until the desired bearing aligns with the sighting line or index mark.
5.2 Sighting Optic
The sighting optic allows for precise readings by aligning the target with the vertical calibration line.
- Open the compass fully, positioning the sighting optic for viewing.
- Look through the sighting optic and align the vertical line with your target.
- Read the bearing directly from the dial through the optic. This method enhances accuracy.
5.3 Clinometer Function
The integrated clinometer measures angles of inclination or declination (slopes and heights).
- Hold the compass on its side, aligning the base with the slope you wish to measure.
- Ensure the clinometer needle is free to move.
- Read the angle directly from the clinometer scale. The range is 0-90 degrees.

5.4 Fluorescent Features
The compass features fluorescent markings on the magnetic orientation arrow and the dial. To activate the fluorescence:
- Expose the compass to sufficient natural or artificial light for a period of time.
- The absorbed light energy will allow the markings to glow in dark or low-light conditions, facilitating night navigation.

5.5 Measuring Scales
The compass includes various scales for map work and distance measurement:
- Centimeter Graduated Scale: Located on the side, clear to read with white paint plating.
- Plotting Graduated Scale: Used for measuring distances on maps, often corresponding to specific map scales (e.g., 1:50,000).

6. Maintenance
Proper care ensures the longevity and accuracy of your compass.
- Cleaning: Wipe the compass with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the compass in its carry case when not in use to protect it from dust and scratches. Keep it away from strong magnetic fields (e.g., magnets, electronic devices) which can demagnetize the needle.
- Water Resistance: The compass is waterproof (IP65 rated), meaning it can withstand splashes and rain. However, it should not be submerged in water.
- Shock Resistance: The metal casing provides shock resistance, but avoid dropping the compass from significant heights.

7. Troubleshooting
If you encounter issues with your compass, consider the following:
- Inaccurate Readings: Ensure the compass is held perfectly level using the bubble level. Move away from any metallic objects or electronic devices that could interfere with the magnetic needle.
- Needle Not Settling: This can be caused by nearby magnetic interference. Relocate to an open area away from power lines, vehicles, or large metal structures.
- Fluorescence Not Glowing: Ensure the compass has been exposed to sufficient light to charge the fluorescent materials.
