Setup
1. Unpacking
Carefully remove the backpack from its packaging. Inspect for any signs of damage during transit. Retain all packaging materials for potential returns or warranty claims.
2. Adjusting Shoulder Straps
When using the backpack in its carrying mode, adjust the shoulder straps to fit comfortably. Loosen or tighten the straps using the buckles located at the bottom of each strap. The backpack should sit snugly against your back, with the weight evenly distributed across your shoulders.

4. Setting the TSA Combination Lock
Your backpack is equipped with a TSA-approved combination lock. The initial combination is typically 0-0-0. To set your personal combination:
- Ensure the lock is set to 0-0-0 and the zippers are disengaged.
- Locate the small reset button (often recessed and requires a pen tip to press).
- Press and hold the reset button until you hear a click.
- Set your desired 3-digit combination by turning the dials.
- Release the reset button. Your new combination is now set.
Important: Remember your combination. There is no master key for personal combinations.
Operating the Backpack
1. Using Main Compartments
The backpack features multiple compartments for various items. The main compartment is spacious for clothing and larger items, often including packing straps to secure contents. The dedicated laptop and tablet compartment is designed with extra padding for electronic devices.

2. Utilizing the Easy Pass Cable System
The Easy Pass system allows you to route charging cables between different compartments. This enables you to charge your devices, such as a phone or tablet, from a power bank stored in another pocket without having to remove them from the backpack. Look for small openings or dedicated channels between compartments.

Maintenance
1. Cleaning Instructions
To clean your Samsonite PRO-DLX 5 backpack, use a soft cloth dampened with mild soap and water. Gently wipe down the exterior surfaces. For stubborn dirt, a soft brush can be used. Avoid harsh chemicals or abrasive cleaners, as these can damage the ballistic nylon and leather components. Allow the backpack to air dry completely before storing.
2. Care for Zippers and Wheels
Periodically check zippers for smooth operation. If a zipper becomes stiff, apply a small amount of zipper lubricant or wax. Keep the wheels free of debris to ensure smooth rolling. Clean the wheel housings regularly, especially after use in dusty or dirty environments.
3. Removing Stickers and Adhesive Residue
If you need to remove stickers or adhesive residue, use isopropyl alcohol, white spirit (naphtha), or paraffin oil. Apply a small amount to a clean cloth and gently rub the affected area. Test on an inconspicuous area first to ensure no discoloration occurs.
4. Storage
Store your backpack in a cool, dry place away from direct sunlight when not in use. Avoid storing heavy objects on top of the backpack to prevent deformation.
Troubleshooting
1. Stiff or Jammed Zippers
If a zipper is stiff, apply a small amount of zipper lubricant or a graphite pencil lead along the teeth. If jammed, gently try to move the slider back and forth. Do not force it, as this can cause damage.
2. Wheels Not Rolling Smoothly
Check the wheels for any trapped debris such as hair, string, or dirt. Remove any obstructions. If the wheels are still not smooth, they may require cleaning or lubrication at the axle points.
3. Difficulty with TSA Lock
Ensure the combination is correctly aligned in the center of the dials. If you have forgotten your combination, unfortunately, there is no way to reset it without knowing the original code. You may need to contact Samsonite customer service for assistance or consider a replacement lock.
