Intelligent Memory Circuit 
The flashlight automatically memorizes the last selected mode excluding Strobe and SOS. 
When turned on again by rotating the toggle switch clockwise or pressing the electronic switch for 0.5 seconds, the previously used Spotlight mode, floodlight mode, or Spot-and floodlight mode will be recalled.

When turned on again by double clicking the electronic switch, the previously used Red light mode, Red flash mode, or UV light mode will be recalled.
*Note: The flashlight doesn’t memorize the previously used brightness level.

Battery Specifications

*Do not use a 16340 or 18650 battery.
**Do not mix batteries of different brands, sizes, capacities, or types. 
**21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

 Battery Replacement

Unscrew the light body and insert the batteries with the anode side (+) towards the light head, then screw the light body back on.
*The flashlight can be used with only one battery inserted, but the brightness is subject to the actual lighting performance.

 Charging

Turn off the flashlight and open the anti-dust cover, then connect the USB Type-C end of the charging cable to the light. Connect the other end of the charging cable to a charging adapter and plug it into an electrical outlet.

When charging, the five indicators will flash green from left to right to indicate the charging status. The normal charging time is about 4 hours from depleted to fully charged. 
 
The LR35R Pro automatically recognizes charging adapters that support PD3.0, PD2.0, and other mainstream fast charging protocols, as well as standard 5 V charging adapters. The maximum charging current is 3 A, and the maximum charging current is 2.5 A for a 5 V input.
Note: Do not charge the flashlight if there is no battery inserted.

 Power Bank Function

Turn off the flashlight and open the anti-dust cover. Connect the USB Type-C end of the charging cable to the light and connect the other end of the charging cable to the device.
 

When discharging, the five indicators will flash green from right to left to indicate the discharging status.
Once discharging is completed, be sure to unplug the cable and close the anti-dust cover.
Note: When charging or discharging, the available brightness levels for the Spotlight and Floodlight range from 200 to 900 lumens; the available brightness level for the Spot-and-Floodlight ranges from 400 to 900 lumens; the available brightness level for the Red light ranges from 60 to 260 lumens; the Red flash operates at its lowest brightness level; the UV light has a fixed brightness level.

 Battery Level Indication 

With the light turned off (locked or unlocked), single click the electronic switch to check the battery status. Each time the light is turned on, the indicator(s) will also indicate the battery level. Single click once again and the indicator(s) will go out, or without any operation the indicator(s) will last for 3 seconds. 

• Five lights on: 100% - 80%
• Four lights on: 80% - 60%
• Three lights on: 60% - 40%
• Two lights on: 40% - 20%
• One light on: 20% - 1%

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until the lowest output is reached. When this happens in the lowest output, one battery level indicator blinks to remind users to recharge or replace the batteries in a timely manner till the battery level runs out.

Intelligent Brightness Downshift Function

Intelligent downshift

When the light head is close to an illuminated object (about 2.36''/60 mm) for more than 1.5 seconds, the flashlight will automatically downshift to 50 lumens to avoid potential danger/burns caused by high temperatures. When the light head is away from the illuminated object for more than 0.8 seconds, the flashlight automatically recalls the previously used brightness level.

On/off 
With the light locked, press and hold the electronic switch for 6 seconds, and the flashlight will blink twice on the Low output (50 lumens) of the Floodlight mode, indicating that this function is enabled.
 
With the light locked, press and hold the electronic switch for 6 seconds, and the flashlight will blink 6 times on the Low output (50 lumens) of the Floodlight mode, indicating that this function is disabled.

 Intelligent Overheat Protection    

The flashlight will accumulate a lot of heat when used at high output levels for extended periods. When the flashlight reaches a temperature of 55°C/131°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 55°C/131°F, the flashlight will gradually recall the preset output level.

 Usage and Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using excellent quality batteries.
• If the light will not be used for an extended period, remove the batteries, or the light could be damaged by electrolyte leakage.
• Lock the light, unscrew the light body half a turn or take out the batteries to prevent accidental activation during storage or transportation.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
• Periodic cleaning of the light and battery contacts improves the light's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
  A: The flashlight is locked.
  Solution: Rotate the toggle switch clockwise to unlock and turn on the flashlight.
  B: Poor battery level.
  Solution: Recharge or replace the batteries.
  C: The contact or contact point of the batteries or flashlight is dirty.  
  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact the distributor.

Warning

• Do NOT place this flashlight in the reach of children!
• Do NOT shine the flashlight directly into the eyes of anyone!
• Do NOT place flashlight head near flammable objects, high temperatures can cause objects to overheat and become flammable/ignite!
• Do NOT use the flashlight in inappropriate ways such as holding the unit in your mouth, doing so could cause serious personal injury or death if the light or internal batteries fail!
• This flashlight will accumulate a significant amount of heat while operating, resulting in a high temperature of the light shell. Pay close attention to avoid burns.
• Turn off and lock the flashlight or remove the batteries to prevent accidental activation when the flashlight is placed in a closed and flammable environment such as pockets and backpacks!
• The LEDs of this flashlight are not replaceable; so the whole light will need to be replaced when any one of the LEDs reaches the end of its lifespan.
