• If, during the 2 seconds period that CK is not
flashing, PF 1 is pressed a second time, the
LED functions will advance one step from
top to bottom through the available options
in the order shown in Table 4.
• PF 1 may be pressed repeatedly during the 2
second period (extended with each press) to
advance to the desired numbered LED func-
tion option.

3.2.1.2 LEDs and Indications
LEDs are used to indicate the operation status of
the BDLC
PD
. Although capable of displaying
three colors, only the green and red colors are
used for the BDLC
PD
. They are grouped by their
function:
• RF Group, displays radio channel status in
green
• RS-232 Group, displays serial port status in
green except the TX LED that also uses red
• ALARM Group, displays fault status in red
3.2.1.2.1 Radio Network Indicators
