,
The RT-B77
HELB
will
carry out a self-test procedure. It will check internal electronic
parameters and the battery’s condition.
During the test the
YELLOW
Test LED (
11
) is blinking. If no failure is detected and not more
than 10% of the battery capacity is lost, the self test finishes with the voice message: “
Test
OK
”. The
green
status LED (
4
) and the
white
function indicator (
2
) will blink 3 times.
If a failure is detected or the battery is not in proper condition (less than 90% of its capacity),
the status LED (

Blinks 4 or 6
times
RED
“Error, Need Service”
Failure in electronics, beacon needs
service
NOTE
The advanced self-test routine (factory setting) activates the complete amplifier circuit of the
transmitter electronics. During this test the RT-B77
HELB
will transmit a RF carrier-signal on
the preselected training frequency for about a ¼ second. So the whole electronics can be
checked, making the test more reliable and conform to legal regulations.
1
At temperatures below -10°C the battery voltage is so low that an error is indicated although the battery is in
good condition. In this case the error message can be ignored.
ATTENTION
If failures are indicated, the beacon has to be brought to service at an authorized
service station before next use.
