FREQUENCY SETTINGS AND POWER UP FOR MX 3000: Powerup At powerup, the unit will retrieve the last used channel, program the PLL with this channel, and display the channel by blinking the LED the same number as the channel number 7 or 8. Displaying Current Channel Push button is located on the board. To display the current channel, press the pushbutton once and release. The current channel will blink. After approx. 5 seconds, the current channel will again blink. Changing to a New Channel / Frequency allocation To change to a new channel, press the pushbutton once and release. The current channel will blink. Press and release the pushbutton again before 5 seconds has elapsed and the channel will increment by 1 and the LED will blink the new channel. Repeat this step until the desired channel is reached, waiting for the blinking to stop each time before pressing the button again. Once your desired channel is reached (7 or 8), wait 5 seconds until the LED again blinks your desired channel. Your new channel is now saved in memory. Channels 7 and 8 have been in use FREQUENCIES: 2450 MHz and 2481 MHz
