ASIC PERATION
RA operates in one of three modes: LOW, HIGH and FLASH.
To turn on RA, plug it into a BatPak, turn on the BatPak by single press-
ing the BatPak power button, and then press the RA button. RA will
power on in the mode it was last in when it was powered off . Pressing
the RA button within two seconds of the last button press will cycle
modes from LOW to HIGH to FLASH with each press.
To turn off RA, wait two seconds or longer since the last button push
and then press the button. RA will power off and remember which
mode it was in when it powered off .

RIGHTNESS DJUSTMENT
With RA in LOW or HIGH mode, push and hold the button to adjust
brightness. While the button is held, RA will cycle through its brightness
settings. When the desired setting is reached, simply release the button.
RA will remember the new setting for that mode. When the lowest or
brightest setting is reached, RA will fl ash three times before adjusting
the brightness in the opposite direction.

LASH ODE
FLASH mode uses the brightness setting from the HIGH mode. With RA
in FLASH mode, push and hold the button to cycle through the available
rates. While the rate is adjusting, RA will fl ash three times at each rate
setting before moving to the next setting. From the lowest fl ash rate
setting, RA will change to an SOS fl ash pattern - three quick fl ashes, fol-
lowed by three long fl ashes, followed by three quick fl ashes. When the
desired setting is reached, simply release the button. RA will remember
the new setting for FLASH mode.

OONLIGHT OWER N ODE
Not many things are more annoying than being blinded by a bright
light when you wake up in the middle of the night. To power on RA in
its lowest light setting regardless of how RA was set at last power off ,
press and hold the button for three seconds. RA will turn on at its lowest
brightness. To turn off RA, wait at least two seconds and press the but-
ton. Moonlight mode is not stored as the last used setting. RA will return
to the last used mode (LOW, HIGH or FLASH) when turned on with a
single button push. Adjusting brightness in Moonlight Power On Mode
will switch RA to LOW mode and store a new LOW brightness setting.

ACTORY ETTINGS
RA comes set from the factory with LOW mode set to 30% brightness,
HIGH mode set to 100% brightness, and fl ash rate at about 5 times per
second. To restore those settings on your RA, Press and hold the button.
After three seconds RA will power on in Moonlight mode. Continue
to hold the button (about twelve seconds total) until RA fl ashes three
times and then shuts off . Release the button. Factory settings are now
restored.

RA produces very bright light! Extended exposure to bright light can harm your eyes.

HERMAL ANAGEMENT
RA was designed to dissipate the heat that accompanies bright lighting.
It is normal for the unit to become warm especially when used at high
brightness. In virtually all real-world conditions, RA will continuously
output full rated brightness. For abnormal or fault conditions, RA has a
mechanism to prevent overheating. If the operating temperature of the
LEDs start to approach their upper limit, power to the LEDs is reduced to
keep them within their safe operating range.
Caution: Ensure that RA is not operated while covered or enclosed. It is
good practice to disconnect RA from the power source when packed
away or not in use.
P M
OWER ANAGEMENT
RA is designed to be used with a high-current, 2A or greater, USB-A
power port. If RA is attempted to be used with a low-current source
such as a computer USB port or a low-current battery pack, RA will try to
adjust its brightness to stay within the capabilities of the power source.
While this may work, it can produce unpredictable and unsafe results.
It is strongly reccommended that RA be connected only to a USB-A
powerport capable of supplying 2A.
