LED Response While Charging
Under normal circumstances, when the charger is plugged in, the LED bar
graph will ramp up repetitively. This indicates that the battery is
undergoing a fast or top-off charge.
When the fast charge is complete and the battery is just receiving a trickle-
charge, the bar graph will stop ramping up and all LEDs in the bar graph
will be off, except the top red LED. This LED will flash quickly once
every 2 seconds.
If the battery is in a very deep discharge state when the charger is plugged
in, it cannot accept a fast charge. If this occurs, only the bottom LED will
flash (on for 2 seconds/off for 2 seconds). This indicates that the charger
is pre-charging the battery at a low current to prepare the battery to receive
the fast charge. Once the pre-charge is complete, the charger will begin
the fast charge and the bar graph will begin ramping up repetitively (as
under normal conditions).
On/Off
The push button switch has various functions that are initiated by pressing
the button for a short or long time (2 seconds):
Pressing and holding for 2
seconds and then releasing Turns on the transmitter and sets the
transmitter to high power, illuminating the
High-power LED. The 5 LEDs display the
sound strength.
Pressing and releasing Sets the transmitter to low power, illuminating
the Lo-power LED. The 5 LEDs display the
sound strength.
Pressing and releasing Turns off the transmitter and all the LEDs.
Battery Test
When the transmitter is off,
press and release the button
to display the battery level. The Sound/Battery LEDs display the relative
battery charge for approximately 10 seconds.
When the transmitter is on,
press and hold the button for
more than 2 seconds to start
the battery test. The Sound/Battery LEDs display the relative
battery charge for approximately 10 seconds.
Accelerometers
The accelerometers connect to the transmitters and may be used when the
location or the transmitter does not allow easy attachment to a pipe or
fitting (using the internal accelerometer). They also may be used when the
transmitter must be located aboveground for good signal performance.
