Frequently Asked Questions - TWM350S NightStick

How to install batteries in the TWM350S light?

Unscrew the screw on the battery compartment door to open. Insert two CR-123 lithium batteries following the orientation indicated on the sides. Close the door and tighten the screw by hand, without over-tightening.

How to mount the light on my firearm?

Ensure the firearm is unloaded and secured. Push the clamping screw of the rail device to open the adjustable portion. Place the fixed portion of the rail into the groove of the tactical rail, align the insert with a slot, then turn the light. Tighten first by hand, then with a coin.

How to activate strobe mode?

On the TWM350S model, quickly press down twice on one of the switches and hold it during the second press. Strobe mode activates. Release to return to neutral.

What type of batteries to use?

Use only CR-123 lithium batteries. Do not use other types of batteries to avoid risk of overheating or damage.

Is the light waterproof?

The manual does not specify a waterproof rating. It is not recommended to expose the batteries to water or salt water. Consider it splash resistant, but not submersible.

What is the warranty for the NightStick TWM350S light?

Bayco Products, Inc. offers a one-year limited warranty from the date of purchase against defects in materials and workmanship. Bulbs (non-LED) are covered for 90 days.

How to clean and maintain the light?

Clean regularly with a dry cloth. Periodically check the tightness of mounting screws. Store in a dry place away from metal objects to avoid short circuits.

Can I use the light without mounting it on a firearm?

The light is designed to be mounted on a firearm tactical rail. Handheld use is possible but impractical due to its shape and switch system.

What to do if batteries leak or overheat?

Immediately stop using the batteries if they emit an unusual odor, overheat, change shape, or show any abnormality. Replace them with new batteries.

WEAPON SAFETY

PLEASE BE SURE TO READ, UNDERSTAND AND FOLLOW THESE SAFETY AND OPERATING INSTRUCTIONS WHEN HANDLING A FIREARM OR THE NIGHTSTICK TWM WHEN MOUNTED ON A FIREARM. FAILURE TO DO SO CAN BE DANGEROUS AND COULD RESULT IN SERIOUS INJURY, DAMAGE TO PROPERTY, OR DEATH.

Use of a firearm under any circumstance is inherently dangerous. SERIOUS INJURY OR EVEN DEATH may result without proper training in the safe handling of fi rearms. Proper training should be obtained from an accredited fi rearms safety program conducted by a qualified instructor.

Read, understand and follow all of the safety instructions that came with your firearm before attaching your new TWM.

Always assume every firearm is loaded and treat that firearm as such.
- Never point a firearm at anything that you are not willing to destroy.
- Never service your firearm or your TWM when mounted on a firearm without first activating the weapon's safety (if applicable), removing the magazine, opening the action and physically and visually inspecting to make sure that no ammunition is installed in the firearm.

WEAPON MOUNTED LIGHT SAFETY

• Nightstick recommends that the TWM should only be activated with the non-trigger hand (support hand) while employing a two-hand grip on the firearm and with the trigger finger fully outside the trigger guard when applicable.

WARNING: FAILURE TO DO SO COULD RESULT IN AN ACCIDENTAL DISCHARGE AND SERIOUS INJURY, DAMAGE TO PROPERTY, OR DEATH.

• Thoroughly practice (employing safe training conditions) with the TWM and an unloaded firearm before using the weapon.

BEFORE ATTACHING, INSPECTING OR SERVICING THE TWM

• Engage the safety on the firearm (if applicable).

• Remove the magazine from the fi rearm (if applicable).

• Open the action and visually and physically inspect the chamber to be sure it is empty.

• Keep the barrel pointed in a safe direction at all times and never place your hand in front of the muzzle.

WARNING: IT IS IMPERATIVE THAT SAFETY MEASURES BE EMPLOYED AT ALL TIMES WHILE HANDLING A FIREARM.

GENERAL SAFETYWARNINGS

NOT FOR USE ABOVE HAZARDOUS LOCATIONS

• DO NOT use in explosive atmospheres, near flammable liquids, or where explosion proof lamps are required.
  DO NOT use in the proximity of vehicles or equipment when there is a risk of flammable liquids coming into contact with the flashlight.
  DO NOT expose the batteries to water or salt water, or allow the batteries to get wet.
• DO NOT store the batteries with metallic objects that may cause a short circuit.

• Immediately discontinue use of the batteries if they emit an unusual smell, feel hot, change color, change shape or appear abnormal in any way.

• Keep out of the reach of children.

STEP 1. INSTALL THE BATTERIES

• To install the included CR-123 Lithium Batteries in the TWM, begin by unscrewing the screw on the battery compartment door. (Image 1) This screw is designed to remain in the battery compartment door once it has been unscrewed, do not attempt to remove it.
• Insert both batteries into the battery compartment paying attention to the battery orientation marking on the sides of the light near the battery compartment door. (Image 2)
• Re-install the battery compartment screw by pressing the door fully closed and then tightening the screw until it is hand tight. Do not over tighten. (Image 3)
  Test the operation of the light (see OPERATION below).

STEP 2. INSTALL THE LIGHT ONTO YOUR FIREARM

The TWM is designed to be easily attached and detached from the fi rearm's tactical rail. However, the fi rearm must have a tactical rail and it must have at least one cross rail slot. The TWM is not designed to be used on a fi rearm that does not have a cross rail slot. IMPORTANT: Your TWM comes with the Universal Insert pre-installed in the slot location that will allow the light to fi t on approximately 70% of the handguns on the market today. If the fi t is not correct for your specific handgun, use the included Allen Wrench to relocate the insert to the slot location that works best for your fi rearm.

• Push inward on the head of the Rail Clamp Tension Thumbscrew to fully open the Adjustable Portion of the Rail Clamp. (Image 4)
• While making sure that your firearm is in a safe condition and that the barrel is pointed in a safe direction, place the fi xed portion of the Rail Clamp into the groove of the tactical rail on your fi rearm and align the Cross Rail Insert with the slot on your fi rearm.
• Rotate the TWM onto the tactical rail (Image 5) and then release the pressure on the Tension Thumbscrew making sure that the TWM is gripping both sides of the tactical rail of your fi rearm and verify that the Cross Rail Insert is fully seated into the tactical rail slot of your fi rearm. (Image 6)

Image 8

• While holding the TWM tightly to the tactical rail of your firearm, fully tighten by hand the Rail Clamp Tension Thumbscrew. (Image 7)
• Then use a large coin (a quarter works well) and fully tighten the Rail Clamp Tension Thumbscrew. (Image 8)

WARNING: NIGHTSTICK STRONGLY RECOMMENDS PERIODICALLY CHECKING TO INSURE THAT THE CROSS RAIL INSERT SCREWS AND THE RAIL CLAMP TENSION THUMBSCREW REMAIN TIGHT. FAILURE TO KEEP THESE TIGHT CAN RESULT IN DAMAGE TO THE TWM AND/OR THE CROSS RAIL INSERTS UNDER CONTINUOUS RECOIL.

STEP 3: TEST FUNCTION OF THE SWITCHES

• Verify that both switches have a full range of movement and that the TWM is operating properly.
  The TWM is now properly installed on your firearm.

OPERATION

Right Down-Momentary On
Neutral Off

Left Down-Momentary On

Left Up-Constant On
Right Up-Constant On Neutral Off

The TWM uses Dual Dependent Locking Switches.

Each switch has 3 positions of operation: Neutral - Off, Down - Momentary-on and/or Strobe (model dependent), Up - Constant-on
- In order to operate one of the switches, the switch on the opposite side must be in the Neutral Position (off).

MOMENTARY-ON MODE

Press down and hold either the left side switch or the right side switch to activate the momentary-on mode. Release the switch, back to the Neutral position and the light turns off.

NOTE: While in Momentary-on Mode on one side of the TWM, the Dual Dependent Locking Switch design of the TWM prevents the switch that is NOT in use from accidentally moving out of the Neutral position. This eliminates the possibility of an unintended activation of the light (i.e. while the left side switch is being held in the Momentary-on Mode, the right side switch is mechanically locked in the Neutral position).

CONSTANT-ON MODE

Press up, click and release either the left side switch or the right side switch to activate the constant-on mode. From the constant-on mode slightly press the switch downward into the Neutral position to turn the light off.

STROBE MODE (350S/850XLS Models Only)

To activate (using either switch), quickly press down twice and hold on the second press. This will activate the strobe. The strobe mode will continue until the switch is released back to the Neutral position.

STROBE WARNING

Exposure to strobing lights may cause dizziness, disorientation, and nausea. A very small percentage of people suffer from photosensitive epilepsy and may experience seizures or blackouts triggered by strobing lights. For more information from the EPILEPSY FOUNDATION about photosensitivity and seizures, please visit www.

epilepsy.com. Anyone who has had symptoms linked to this condition should consult a doctor before using this product.
