Operating Instructions
Power On/Off and Mode Selection
The flashlight is operated using the tail cap button.
- To turn ON/OFF: Press the tail cap button firmly until it clicks.
- To cycle through modes: With the flashlight ON, lightly press the tail cap button repeatedly to cycle through High, Medium, and Low light modes.
Focus Adjustment (SLIDE FOCUS & BEAM LOCK)
The TX17R features a dynamic focusing system:
- SLIDE FOCUS: To adjust the beam from a tight spot to a wide flood, simply push or pull the bezel (the front part of the flashlight) forward or backward.
- BEAM LOCK: To lock the beam in a specific focus position, twist the bezel. This will prevent accidental changes to the beam pattern during use. Twist it back to unlock.

Maintenance
To ensure the longevity and optimal performance of your Coast TX17R flashlight, follow these maintenance guidelines:
- Cleaning: Wipe the flashlight body with a clean, soft cloth. For the lens, use a lens cleaning cloth and solution to avoid scratches.
- Lubrication: Periodically apply a thin coat of silicone grease to the O-rings and threads to maintain water resistance and smooth operation.
- Battery Care: Store the battery in a cool, dry place when not in use. If storing for extended periods, charge the battery every 3-6 months to prevent deep discharge.
- Avoid Extreme Temperatures: Do not expose the flashlight to extreme heat or cold for prolonged periods, as this can affect battery life and internal components.
Troubleshooting
If you encounter issues with your TX17R flashlight, try the following solutions:
- Flashlight not turning on:
- Ensure the battery is fully charged.
- Check that the battery is inserted with the correct polarity.
- Tighten the tail cap securely. A loose tail cap can prevent electrical contact.
- If using CR123 batteries, ensure they are fresh and correctly installed.
- Dim or flickering light:
- Recharge the battery. Low battery power can cause dimming.
- Clean the battery contacts and the flashlight's internal contacts with a clean cloth.
- Ensure the bezel is not stuck between focus settings. Adjust it fully to spot or flood.
- Focus mechanism is stiff:
- Ensure the BEAM LOCK is disengaged (twisted to the unlocked position).
- Clean the area around the bezel and apply a small amount of silicone grease if necessary.
