Information LEDs
The KE 3500 has five LEDs that display a range of important but easy-to-use information about the current
status of the device. From left to right the LEDs mean:
DSL CRC – orange
This LED lights when a CRC (checksum error) near end or far end is recognized. These errors (fewer than 10)
can arise after a connection has been established. In any case, check if the counter is still counting to
determine if other causes (faults) exist. You can access the error counter menu in the respective test menu.
DSL LOSS – orange
After a connection is established in non-resync mode, a DSL loss event is displayed here and also signaled
with an intermittent tone for 10 seconds. The tone can be stopped by pressing SEL once.
DSL L1 – green
When the KE3500 is activated in xDSL Mode, this LED begins to flash at 2 Hz to signal Ready Status. It is
waiting for a carrier. As soon as this is detected LED flashes at 4 Hz until the connection is established, and then
it is lit steadily as long as the connection exists.
BATT CHRG – green and red
This display is active even when the KE3500 is turned off. The green LED indicates that the power supply or
charger is inserted and is supplying power. The red LED signals that the battery is in charging mode. This
produces a green/red or orange display during charging. Once controlled charging is complete, the red LED
turns off and only the green LED lights to signal that the power supply or automatic charger is still active and
that charging is complete. However, this does not necessarily mean that the battery is fully charged!
The power supply enables the KE3500 to be charged and operated
SIMULTANEOUSLY
. The car charger only
charges the battery.
Switching On
The KE3500 works with an operating system that has to be
booted. The boot menu with various device parameters
such as the hardware and software versions appears at the
end of the booting process. After this you can bring up the
main menu immediately by pressing any button.
