Operating Modes
The LA28 can be used in one of three operating modes. As outlined in
their descriptions, the duration of each mode is estimated using a 76°F
ambient temperature. As the temperature moves away in either
direction, the estimated battery life will diminish. The further away it
moves, the more significant the reduction of usable battery life.
The modes are as follows
High Power
High power mode produces the brightest, most
intense light. To turn the light on in high power mode,
press and release the power button.
In this mode, a fully charged battery will last for
approximately 1.5 hours of continuous use.
Battery Saver
Battery Saver mode is used to extend battery life
when a less intense light output is acceptable. To
change to Battery Saver mode, turn the light on in
high power, then press and hold the power button.
When you see the light output has been reduced,
release the button.
In this mode, a fully charged battery will last for
approximately 3 hours of continuous use.
Alert Mode
Alert mode produces a flashing light. To turn the light
on in alert mode, with the power off, press and hold
the power button until the light begins to flash.
In this mode, a fully charged battery will last for
approximately 3.5 hours of continuous use.
IMPORTANT! While the LiFe portable light is
capable of flashing, it is not a warning light!
Critical Mode
When there is approximately 15 minutes of usable
battery life left, the light will automatically switch
to critical mode. Until the battery has been
recharged, no other mode of operation is
available.
During Critical mode, light output is reduced to
10% of full intensity.
When the light has switched to critical mode, it
must be recharged before it can be returned to
service.
ONCE THE LA28 HAS SWITCHED TO CRITICAL
MODE, IT WILL TAKE APPROXIMATELY 6 HOURS
TO FULLY CHARGE THE BATTERY.
Angle Adjustment
The angle of the projected light may be adjusted as needed by rotating
the Angle Adjustment Knob. The total sweep is 180° in 15° increments.
Battery Removal / Installation
1.
Remove the 12 screws securing the bottom cover to the housing.
Carefully lift the bottom cover away from the housing and
