General Operation

1. The P25 utilizes a 2-stage switch similar to a camera shutter button.
The light’s numerous functions are selected according to the depth the
switch is pressed.

2. With the light turned on, press the switch partway down in quick
succession to cycle through the brightness levels: ultra-low, low,
medium, high, and ultra high.

Operating in Turbo Mode:

With the light turned on, press the switch partway down and hold to
activate turbo mode.

Note: For user safety and to prevent overheating / failure, the P25 will
automatically switch to high mode after twenty minutes of use in Turbo
mode. Press the switch partway and hold to reactivate turbo mode when
needed.

Standby Mode

With the light turned on or in the standby mode, press the switch all the
way down and release within one second to enter into standby mode. In
this mode, the light will consume small amounts of power to maintain the
settings in the MCU (micro control unit) but appear to be turned off. When
in standby mode the power indicator light will flash once every two
seconds to show the location of the light.To exit standby mode, simply
press the two-stage switch all the way down or press the tail switch to
turn the light off.

Tips:

When in standby mode，the P25 can also be used as a side-switch
flashlight, all functions and brightness levels can be easily accessed via
the 2-stage switch.

Special Strobe / SOS mode and
Location Beacon

With the light turned on, press the switch all the down and hold to enter
strobe mode. When in strobe mode, press the switch partway down to
cycle through SOS, location beacon and strobe modes. To select any of
these modes simply release the switch when it is displayed. To turn off
the light (enter into standby mode) fully press and release the switch.

Charging Function

The P25 is capable of charging a protected 18650 li-ion battery via the
included USB cable. Simply install a protected 18650 li-ion cell, plugging
one end of the USB cable into the flashlight and the other end into a
universal USB port / adaptor as shown in the adjacent image, and the
P25 will take care of the rest. The P25 needs to be turned on in order
enter charging mode.

4. The P25 is equipped with an intelligent charging circuit that detects
when an 18650 battery is fully charged and terminates the charging
current. The P25’s blue indicator light will illuminate steadily when a
battery is fully charged.

Tips:

The P25 needs to be turned on using the tail cap switch in order enter
charging mode.

Warning:

USB charging functionality is designed for 18650 rechargeable li-ion
only. Do not attempt to charge non-rechargeable batteries such as
CR123 or other types of rechargeable cells such as RCR123 batteries.

Power Tips

1. With the light switched on, the power indicator will blink once every
two seconds when power levels reach 50%.

2. With the light switched on, the power indicator will blink rapidly when
power levels are low.

3. Half press the switch when the light is put into standby mode or under
charging mode, the power indicator light will blink in various patterns
to indicate the battery voltage (accurate to ±0.1V). For example, when
the battery voltage is at a maximum charge of 4.2V, the power
indicator will blink 4 times in quick succession, followed by a one
second pause and two more blinks, indicating a total battery voltage of

4.2V.

Changing / Charging Batteries

When the power indicator blinks rapidly it means the batteries need to be
replaced or recharged. Alternatively if the light becomes dim or
unresponsive to adjustment this also indicates batteries need to be
replaced or recharged.

Maintenance

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

Charging Indicator Light

1. Fully charging a depleted 18650 battery takes approximately 6 hours.

2. Under normal charging conditions, the blue indicator light will blink
once every 0.5 second.

3. If a problem is detected during the charging process, the P25 will stop
charging and the blue indicator will blink rapidly. This is usually caused
by a faulty / incorrectly inserted battery, or if the light has not been
turned on using the tail cap switch.
