different memory locations. For the repeater to operate,
you must have one memory location programmed with
operating frequencies.
NOTE: There 1089 possible combinations of TX and RX
channels available. Your Echo 6 may only hold 16 of
them in its memory at one time.
NOTE: To reprogram a channel memory location that
has previously been used, simply use the above
procedure - you will overwrite the old frequency
combination with the new one you select.
E.) Set the SQUELCH control
1.) Set Repeater Operating Mode Switch to MON (center postion)
2.) Adjust the squelch control found on the control panel fully to
the counter-clockwise position.
3.) Insert the male mono mini plug of the supplied earphone into
the female jack on the Echo 6 panel marked RECORDER. The
noise you hear coming from the earphone is called White Noise.
4.) While listening, turn the squelch control clockwise just until
the white noise goes away, and the receiver becomes 'quiet'.
This is called the "Critical Squelch" point. Critical Squelch is the
optimum point of squelch for the receiver.
5.) Squelch may then be adjusted to the operators preference at
any time by turning the control clockwise to increase, or counter-
clockwise to decrease the amount of squelch in the circuit.
6.) When you are finished, remove the earphone from the jack.
NOTE: ALWAYS HAVE AN ANTENNA CONNECTED TO THE
ECHO-6 WHEN SETTING THE SQUELCH CONTROL.
G.) Select operating configuration via REPEATER OPERATING
MODE SWITCH.
MONITOR MODE: To receive and monitor/record reception only,

REPEAT MODE: To rebroadcast reception, and monitor, place
switch in the RIGHT position (RPT).
