Operating Instructions

HA20 utilizes a two-stage switch to enable various operations based on
finger pressure.

Battery Installation

Insert two AA batteries with the positive (+) and negative (-) ends
corresponding to the diagram below. Align the cover .
Note: Each time batteries are inserted, the red LEDs will blink to indicate
battery voltage. Please refer to the "Power Tips" section in this manual
for details.
Caution: DO NOT direct the beam towards human or animal eyes when
using HA20.
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
