OPERATING INSTRUCTIONS

Thank you for selecting the NSR-9850. Save this manual. Please read this manual before using this

product. It includes important safety and operation information. Be sure to charge the light fully before

first use. A battery is fully charged when the charger light is green.

CHARGING

Fully charge this light before the first use. If the battery is new or has been unused for several months,

several charge and discharge cycles may be needed to reach full battery capacity. To reach maximum

performance, run the light to completely discharge the battery and then recharge. Each charge cycle

will extend the operation time until maximum capacity is achieved. The charge time for maximum

capacity is approximately 3 hours.

Use only the supplied charge platform, battery and AC or DC adapter. The maximum allowable DC input

is 15VDC.

 For best performance, charge the light when the LED’s start to dim.
 Connect the AC power adapter to the charging platform. The green indicator will light.
 With the floodlight facing forward, slide the light into the charging platform until the contacts

snap into place.

 The red light on the charging platform indicates the light is properly inserted into the charging

platform and charging. The light remains red until the battery is fully charged. At full charge,

the light turns green. The total time to full charge varies depending on the remaining charge in

the battery pack.

 The charging platform provides a trickle charge to a fully charged battery pack.
 Runtime: Flashlight or floodlight up to 9 hours, dual-light 4 hours, flashlight strobe or floodlight

strobe 24+ hours, flashlight strobe with constant floodlight 7 hours.

SAFETY

specifically disclaims liability for other than intended use.

 Remove the light by pulling up and out of the charger. Insert the light into the charger with a

downward motion relative to the charging platform.

MOUNTING CHARGER PLATFORM

Mounting the charger platform requires two #8 screws (not provided). Use the supplied 12VDC fused

auto adapter plug for temporary vehicle installations. For permanent wiring, the installation must be

fused using a 3 amp in-line fuse. The DC input terminal that connects to the base of the charger

platform is center-positive. Installation should be performed by a professional installer.

OPERATION

Two body switches control all functions of the 9850. This light has a Flashlight, Floodlight, and Dual-

Light function. It also has a strobe function. The strobe flashes at approximately 2 flashes per second.

TIPS TO EXTEND BATTERY LIFE

This light has a NiMH battery pack that does not have a memory effect.

Charging the battery pack often helps extend its useful life.

 A new light or one that has not been used for a long period of time may not accept a full charge

initially. This is normal and does not indicate a problem. Fully discharge and then charge the

unit several times to condition the battery pack for full capacity.

 Charge the unit after each use, whether the light is fully discharged or not.
 Store the light at room temperature.
