4.0 Setup
Transmitter setup is accomplished without software. Access the programming but-
tons and switches by lifting the access door as shown in figure 2.
4.1 Power up Sequence
When the A753 is pow-
ered, LEDs light in the
following sequence:
Power, RF Link, A1, A2.
Then either A1 or A2 will
blink (4) times – this will
indicate Normal RF Mode
or Repeater Mode – see
Section 4.4 for configura-
tion. After a brief pause
all LEDs will report the
appropriate status.
4.2 Mode Switch Selec-
tion
The mode switches are
used for calibration, RF
channel selection and
RSSI (received signal
strength indication) activation. Figure 3 shows the function of each switch position.
Return all switches to Mode 0 for normal operation. Refer to figure 3 for mode
switch settings.
