The light is in Low Battery
state
The light will flash once every
60 seconds
Charge the light
The light is
unresponsive to
pushbutton and radio
commands
The light battery has been
discharged beyond Critical
Low Battery
Measure the voltage on each
of 4 cells, they should read
no less than 2.0V
If the cells are lower than this, Critical Low
Battery Recovery may be attempted
alternately change the battery
The light is configured in a
different group than is active
on the controller
Try using the controller in All
Groups
Reassign light to a known group, or find out
which group the light is assigned to.

The light is encountering
radio reset problem.
Perform the Radio Health
Diagnostic (section
5.7.2
Radio Health Diagnose

)
Install antenna(s) by tightening firmly by
hand
If yes: no problem
The ambient brightness
level is above 500 lux
Darken the environment and
wait 10 seconds, does light
turn on?
If no: is it in standby?
The light is off in
Autonomous Mode
Lights in close proximity are
shining on the light in
question
Inspect distance between
lights to see if one light within
the cluster is on.
Turn off the surrounding lights
The light flashes
briefly every 10
seconds
The light is in Critical Low
Battery (resetting)
The red indicator LED will be
on for the majority of this time
Perform Critical Low Battery Recovery
operation or replace the battery.
The light flashes
once every minute.
The light is in Low Battery
state
Low battery state can be
confirmed per steps in
section
4.3.2 Push Button
Operation
(press sequence

cycle?
If no: Is the power
outlet on? (Do
other devices
function when
plugged into the
outlet?)
If yes: Is the charger
functioning correctly?
(In a dark place,
connect the charger
to an A704-5 light
briefly: does the
amber LED flash?) If
so, the charger is
working correctly.
If the controller still
does not work,
