On/Off Operations

To turn HA20 on: Press the switch all the way down until a “Click” is
heard;
To turn HA20 off: Press the switch all the way down again until a “Click”
is heard.

Brightness Levels

With HA20 turned on, press the switch partway down to cycle through
brightness levels: ultralow, low, medium, high-turbo. HA20 has memory
effect for brightness levels. Each time it is turned on, HA20 will enter the
brightness level last used.

Special Modes(Police Warning/Location
Beacon/SOS)

With HA20 turned on, press the switch all the way down for over one
second to enter police warning mode. Press the switch partway down to
cycle through location beacon-SOS-police warning modes. To exit, press
the switch all the way down to turn HA20 off.

Constant/Flashing Red Illumination

With the light turned off, press the switch partway down for over one
second to enter constant red illumination mode (7 hours and 25 minutes
runtime at 16 Lumens);
In red illumination mode, press the switch partway down to switch
between constant and flashlight red illumination. To exit, press the switch
all the way down to turn HA20 off.

Power Tips

Upon battery installation, the red LEDs will blink to indicate battery
voltage (accurate to 0.1V). For example, when battery voltage is 2.4V,
red LEDs blink twice, followed by a 1.5 second pause, and blink four

times.
With HA20 turned off, pressing the switch partway down will have red
LEDs indicate battery power levels:

1. Three times for battery levels over 50%;

2. Twice for battery levels below 50%;

3. Once for battery levels close to depletion (below 10%).

Advanced Temperature Regulation
(ATR)

Advanced temperature regulation (ATR) technology allows HA20 to
dynamically adjust output performance based on its internal temperature.
This prevents damage from overheating and prolongs its working life.

Changing Batteries

Batteries should be replaced when any of the following occurs: The
output appears to be dim or unresponsive.
