APT 06 should work normally The APT 06 has no power on off switch As soon as power is plugged in it will power up and the 5 red LEDs start blinking all together for about 5 seconds Only applicable for the model APT 06AD You can activate the antenna diversity circuit by pressing the push button once during the 5 seconds blinking period just after power up If you don t press the button during the b...
