Some finer points of button usage include:
To more quickly cycle through the command levels, try releasing the button briefly
when each amber flash occurs, and then pressing it down again (e.g. for command
level 3: hold the button until the amber LED flashes once, then release it briefly and
hold it down again until the amber LED flashes twice, release briefly and hold down
until it flashes three times).
Example: To set the Model A704-5 to Ship Mode, follow these steps:
1. Hold the push button down. The amber indicator LED will blink once after approximately two seconds
and twice after approximately four seconds.
Release the push button.
Immediately press the button once. The green LED will blink once to confirm one press. The red LED will
then briefly flash as the light enters Ship Mode.
The Model A704-5 is now in Ship Mode.
In the following sections, shorthand terminology is used to refer to particular push hold
/ button press sequences in the format: [x, y] specifying hold for x amber flashes, press
y times followed by y green flashes. For example, [0, 5] is Flash Toggle; [4, 1] is
Battery Check. [0] = no hold; proceed directly to the press.
Button Sequence [0, 1]: Standby Mode
Button sequence [0, 1] puts the Model A704-5 in Standby Mode. This will immediately extinguish the light,
and the light will resume autonomous operation at its last set Autonomous Output Mode after detecting a
day-to-night transition.
If a light is in a Temp Mode and is put into Standby Mode, it reverts to the last programmed Autonomous
setting (and will turn on in the next day-night transition).
Button Sequence [0, 2-4]: Autonomous Output Modes
The Model A704-5 has three Autonomous Output Modes: low, medium, and high intensity. These are the
standard operating modes for dusk to dawn operation when the light is deployed differing by light
intensity. The Autonomous Modes operate independently of an external power source as long as local
sunlight conditions can adequately sustain the battery state of charge.
If the light is put into an Autonomous Mode during the day or in a bright environment,
the main LEDs will remain off until the light senses nightfall. If the Model A704-5 is
programmed to the Autonomous Mode at night or in low-light conditions, the main
LEDs will be on until daylight is detected.
Button [0, 5]: Flash Toggle
The flash toggle setting alternates the light between steady-on or flashing. In Flash Mode, the light
flashes at once per second (0.3 seconds on, 0.7 seconds off). The three Autonomous Output Modes (low,
medium and high) can be either steady-on or flashing.
When in Autonomous Mode, the Model A704-5 may automatically decrease its intensity if it detects that it
does not have sufficient battery charge to continue autonomous operation at that brightness. When the
Model A704-5 detects that it is receiving sufficient battery charge to resume autonomous operation at the
original user setting, it revert to its original intensity. For more information, see section
