Setup and First Use
Battery Installation and Charging
The Polysteel 600R offers dual power options: a rechargeable ZITHION-X™ lithium-ion battery pack or 4xAA alkaline batteries. To install the rechargeable battery pack, unscrew the tail cap and insert the pack with the positive (+) terminal facing the head of the flashlight. For alkaline batteries, use the provided adapter and insert 4xAA batteries according to the polarity indicators.
To charge the ZITHION-X™ battery pack, connect the included USB charging cable to the micro-USB port on the battery pack and plug the other end into a USB power source (e.g., wall adapter, computer USB port). The charging indicator light will show charging status. A full charge provides up to 40 hours of runtime, with a typical charging time of approximately 5.75 hours.

Focusing the Beam (PURE BEAM® Optical System & TWIST FOCUS™)
The flashlight is equipped with TWIST FOCUS™ technology, allowing you to seamlessly transition between two distinct beam types: the Ultra View Flood Beam and the BULLS-EYE™ Spot Beam. To adjust the focus, simply twist the head of the flashlight. Twist one way for a broad, even floodlight, and the other way for a concentrated spot beam with a bright center.

USB Power-Out Feature
The ZITHION-X™ rechargeable battery pack includes a convenient USB power-out port. This allows you to use your flashlight as a portable power bank to charge other small electronic devices, such as smartphones or GPS units, in emergency situations or when away from a power outlet. Simply connect your device's USB charging cable to the USB-A output port on the battery pack.

Maintenance
Cleaning
To maintain optimal performance, keep the flashlight clean. Wipe the exterior with a damp cloth as needed. Avoid using harsh chemicals or abrasive cleaners, as these can damage the polyethylene body. Ensure the lens is clean for maximum light output.
Battery Care
For the rechargeable ZITHION-X™ battery, avoid fully discharging it frequently to prolong its lifespan. If storing the flashlight for an extended period, it is recommended to charge the battery to about 50% and store it in a cool, dry place. If using alkaline batteries, remove them if the flashlight will not be used for a long time to prevent leakage and corrosion.
