USAGE INSTRUCTIONS

Briefly press the rubber switch to turn the HL20AAII on/off. 

The HL20AAII provides three lighting options:

 

 

Maximum brightness: 100% output

 

Custom brightness: eight selectable modes ranging from 10% to 
80% output

 

Strobe / SOS: police strobe, slow strobe, rapid strobe and SOS.

Operating Instruction:

 

 

i) To turn the HL20AAII on, briefly press the rubber switch. The default 
setting is maximum brightness (100% output). 

 

ii) To access custom brightness mode: with the HL20AAII turned on 
(in either max or custom mode), hold the switch down for more than 
2 seconds and the HL20AAII will cycle through 8 levels of output. 
When a desired output is displayed simply release the button to set 
the brightness. 

 

iii) The HL20AAII has 3 hidden strobe modes and 1 SOS mode. To 
access these modes simply hold down the power button for 2 
seconds with the unit turned off and release. To cycle to the next 
strobe / SOS mode once again hold for 2 seconds and release. To 
exit strobe / SOS mode simply press the switch once (turns the 
HL20AAII off).

Low battery warning:

 When the battery capacity gets very low 

(approx. 20%), the HL20AAII will emit 10 successive blinks in 8 seconds. 
This is a reminder that the battery should be replaced.

Reverse polarity protection:

 When a battery is inserted incorrectly, 

a special protection circuit will activate and automatically prevent 
operation to ensure the safety of the HL20AAII and its user.

The HL20AAII is also designed with intelligent over-discharge 

detection. If battery voltage reaches a critical lower limit, the HL20AAII 
will automatically turn off, at which time the battery should be 
replaced as soon as possible.
