4.1 Power up Sequence  

When the A750 is powered, 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 configuration.  After a brief pause 
all LEDs will report the appropriate 
status. 

 

4.2 Mode Switch Selection 

 

The mode switches are used for RF 
channel selection and RSSI 
(received signal strength indication).  
Figure 3 shows the location of the 
mode switches, program switch and 
reset switch.   

 
Note: b000 is binary 000, the 
decimal equivalent of decimal 0. The least significant bit is switch position 3. 

 

Return all switches to Mode 0(b000) for normal operation.  Refer to figure 3 for switch mode 
settings.
