NITECORE P20i UV i-Generation 21700 Dual Output Flashlight User Manual

NITECORE P20i UV i-Generation 21700 Dual Output Flashlight User Manual

Operating Instructions

Battery Installation

Insert the battery(s) as illustrated and screw to tighten the tail cap.Note: After the battery insertion, the power indicator will flash to indicate the battery voltage. Please refer to the “Power Indication” section of this manual for more details.

Warnings:

  1. Ensure the battery(s) is/are inserted with the positive end towards the The product will not work if the battery(s) is/are incorrectly inserted.
  2. CAUTION! Possible dangerous radiation! Don’t look into the light! May be dangerous for your eyes.
  3. When the power level is low, please stop using the product and replace or recharge the battery to prevent damage to the battery.
  4. When the product is kept in a backpack or left unused for prolonged time, please remove all batteries to prevent accidental activation or battery leakage.
  5. DO NOT submerge the light into any liquid when it is hot. Doing so may cause irreparable damage to the light due to the difference of air pressure inside and outside of the tube.

Charging Function

The P20i UV is equipped with an intelligent charging system. As illustrated, after inserting the battery and tightening the tail cap, use the USB cable to connect an external power supply (e.g. a USB adapter or other USB charging devices) to the charging port to begin the charging process.

  • During the charging process, the power indicator will flash slowly to inform the user
  • When the battery is fully charged, the P20i UV will cease the charging process and the power indicator will become steadily turned on to inform the user
  • When the light is on, connecting to a power source will automatically turn the light The light will return to its previous status when it is disconnected from the power source.
  • The charging time for a 21700 Li-ion battery (4,000mAh) is 3 hours 30 minutes. (Charged via the 5V/2A adapter)

Tactical Momentary Illumination

Half press and hold the Power Button to turn on the light momentarily. Release to turn it off.

On / Off

  • On: When the light is off, press the Power Button until a click sound is heard to turn it on
  • Off: When the light is on, press the Power Button until a click sound is heard to turn it off.

User Mode Selection

The P20i UV provides 2 user modes for different users and situations.

  • Daily Mode (Default Setting): In this user mode, the P20i UV will memorize and re- access any of the 3 brightness levels, UV or STROBE Mode when reactivated, unless it has been switched to the other user mode.
  • Tactical Mode: In this user mode, the P20i UV will only memorize and re-access the HIGH Level or STROBE Mode when reactivated, unless it has been switched to the other user mode.

To select a desired user mode:

  1. Ensure the tail cap is fully tightened.
  2. Keep holding the Mode Button (STROBE READY™) on the tail cap and  the flashlight will access the STROBE Mode while simultaneously loosening the tail cap.
  3. Once the tail cap has been loosened, the primary white LED will indicate a user mode selected by flashing once for Daily Mode and flashing twice for Tactical Mode.
  4. Release the Mode Button (STROBE READY™) and tighten the tail cap.

Brightness Levels

  • Daily Mode: When the light is on, short press the Mode Button (STROBE READY™) to cycle through the following brightness levels: UV – LOW – MID – HIGH
  • Tactical Mode: When the light is on, short press the Mode Button (STROBE READY™) to cycle through the following brightness levels: HIGH – MID – LOW –UV

STROBE READY™

  • When the light is off in either user mode, press and hold the Mode Button (STROBE READY™) to access the STROBE Release to turn it off.
  • When the light is on in either user mode, long press the Mode Button (STROBE READY™) to access the STROBE Mode. Short press the Mode Button (STROBE READY™) to return to the previous status, or click the Power Button to turn off the light

Power Indication

  • When the battery is inserted, or the flashlight is disconnected from the power source during the charging process, the power indicator will flash to show the battery voltage (±0.1V). For example, when the battery voltage is at 4.2V, the power indicator will flash 4 times followed by a 1.5-second pause and 2 more flashes. Different voltages represent the corresponding remaining battery power levels:

1×21700 battery

2×CR123 batteries

  • When the light is on, the power indicator will indicate the remaining battery
    1. Being steadily turned on indicates that the power is above 50%.
    2. Flashing slowly indicates that the power is below 50%.
    3. Flashing quickly indicates that the power is below 10%.
Note:
  1. When using two CR123/RCR123 in series, the indicator will show the average voltage between the two batteries.
  2. The batteries should be replaced or recharged when the output appears to be dim or the flashlight becomes unresponsive due to low power.

ATR (Advanced Temperature Regulation)

The integrated ATR technology regulates the output of the P20i UV according to the working condition and ambient environment to maintain the optimal performance.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
