B- The right cutout groups two tactile (membrane) switches (PF1 and RESET).
3.2.1.1 Front Switches
The BDLC
PD+
uses two membrane-type switches labeled:
•
RESET
•
PF 1
These switches indicate contact by emitting a short BEEP tone when
pressed.

3.2.1.1.1 Reset
Pressing Reset produces the same result as powering OFF and ON again. It restarts the microprocessor,
the peripherals and invokes the on-board diagnostics. BDLC

’s radio modules’ internal flash-memories
are read and their values are loaded in system SRAM CPU flash-memory.
Normally, pressing Reset results in one short BEEP tone followed by all LEDs coming ON for about four
seconds. Then, the LEDs flash in a “ripple” pattern for close to two seconds indicating diagnostics are in
progress. At the end of this period, all LEDs should be OFF except CK that should flash about six to
eight times per second.

Expect an additional two seconds delay for CK to start flashing and the UF indicator to come ON if the
radio assembly is not connected or not powered (see section 3.2.1.5.4 for Alarm details).

3.2.1.1.2 PF 1
PF 1 is a multi-function switch:
•
It clears LED error indications
•
It initiates test transmissions
•
It sets the function of the RS-232 LEDs
3.2.1.2 Clearing Errors
Major and minor error LED indications remain lit on the front panel until:
•
The unit is RESET
•
The unit is powered OFF and ON again
•
PF 1 is pressed
The PF 1 switch can be pressed at any time to clear an error display without affecting normal operations.
3.2.1.3 Test Transmissions
To select a pattern and begin transmission, start by pressing and holding PF1. It beeps once, all five
RS232 LEDs light; listen for a second beep followed by a third beep. After two seconds, the unit beeps
and goes in “TX Select” mode with only the three rightmost RS-232 LEDs now used as selection indic a-
tors. Only release PF1 after the third beep.

Start of selection must be made within two seconds. If not, the unit will default to pattern one and
start test transmitting.
