ECHO-6
SURVEILLANCE REPEATER
OPERATING INSTRUCTIONS
OPERATIONS
A.) Check Repeater Operating Mode Switch.
This is a three position rotating switch:
RIGHT Repeater's Transmitter and Receiver On (RPT)
LEFT System Off (OFF)
CENTER Receiver Only On - Monitor mode (MON)
Set the switch in the OFF position.
B.) Iinstall antenna in a position for maximum performance.
The antenna supplied with the standard ECHO-6 is a
unity gain quarter wave magnetic mount antenna.
Attach the female BNC connector found on the cable
end of the antenna on to the male BNC connector
marked ANT on the ECHO-6's outside panel.
The antenna's magnetic base should be installed on a
flat metal surface. An approximate radius of 19" around
the magnetic base will result in maximum antenna
performance efficiency.
C.) Select 12 VDC power source and connect to ECHO-6.
INTERNAL BATTERY
No additional setup is necessary to use internal battery.
EXTERNAL 12 VDC (Cable supplied)
1.) Align 4 pin locking female connector found on the
end of the cigarette lighter plug cable with the male
connector on the ECHO-6's outside front panel marked
PWR.
2.) Push connectors together, then turn the locking
sleeve on the cable end connector clockwise until it
stops. Do not overtighten.
3.) Connect the cable end to any appropriate 12 VDC
power source. Attach the RED cable lead to the source's
positive (+) 12 VDC terminal, and the BLACK lead to the
source's negative (-) terminal.
WARNING: DO NOT CONNECT POWER SOURCE TO
REPEATER IN REVERSE POLARITY CONDITION!
D.) Select Operating Frequencies via 4 key KEYPAD on the control
panel.
The ECHO-6 comes ready to be operated on any 12.5
Kc spaced frequency that falls +/- 200 Kc from a user
supplied center frequency. The transmit and receive
frequencies can be programmed separately, giving the
operator a large number of frequency combination
possibilities.
In addition, the Echo 6 has 16 separate channel memory
locations (numbered '00' to '15') so you can preprogram
and store 16 different combinations of transmit and
receive frequencies into the memory.
1.) Turn Echo-6 ON by rotating the OFF/MON/RPT
switch to the MON position.
2.) Select channel to be programmed
a.) Press the CHNL button on the keypad.
b.) Observe the LCD Display.
c.) Using the UP or DOWN arrow keys, step to
the channel number you wish to program.
d.) Press the CHNL key again to lock in the
selection.
3.) Select transmit and receive frequencies to be used.
a.) Press the FREQ button on the keypad. This
will allow you to program your receive frequency.
b.) Observe the LCD Display.
c.) Using the UP or DOWN arrow keys, scroll
through the available frequencies until the display shows
you the frequency you wish to use.
d.) Press the FREQ button again. This now
allows you to program your transmit frequency.
e.) Using the UP or DOWN arrow keys, scroll
through the available frequencies until the display shows
you the frequency you wish to use.
f.) Press the FREQ button again to lock in the
frequency combination.
NOTE: You can repeat this procedure for each of the 16
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,
place switch in the CENTER position (MON).
REPEAT MODE: To rebroadcast reception, and monitor, place
switch in the RIGHT position (RPT).
H.) Select Memory Channel for correct frequency operation
a.) Press the CHNL button on the keypad.
b.) Observe the LCD Display.
c.) Using the UP or DOWN arrow keys, scroll to the
channel number you wish to use.
d.) Press the CHNL key again to lock in the selection.
OPERATING NOTES:
1.) Never Operate the ECHO-6 with the REPEATER OPERATING
MODE SWITCH in the RPT (REPEAT) position without having an
antenna connected to the unit.
2.) Keep the inside of the ECHO-6 dry. If it does get wet, wipe it dry
immediately. Liquids might contain minerals that can corrode the
electronic circuits and cause extensive damage.
3.) Handle the ECHO-6 with care. Dropping the unit may damage circuit
boards, the case, and/or the connectors rendering the unit inoperable.
4.) There are no user-serviceable parts in the ECHO-6. If for some
reason the unit needs service, please return it to the factory.
5.) Before using this equipment in any active investigation, please check
its operation and the operation of all other electronic components in your
system. Be sure to use fresh or fully charged batteries at all times for
optimum performance.
6.) Set Repeater Operating Mode Switch in the OFF position when not in
use.
7.) When using the earphone to monitor the reception in the ECHO-6,
the volume is fixed and can not be adjusted.
8.) Performance of the repeater is subject to many conditions. Of critical
importance is the placement of the antenna. Consult your salesperson
for more information.
9.) The LCD display are only illuminated after any key on the keypad is
pressed. If any key on the keypad is not depressed for 10 seconds, the
illumination automatically turns off.
10.) Make sure the Repeater Operating Mode switch is in the OFF
position when the repeater is not in use.
11.) CLEARING ENTIRE MEMORY
You can clear the entire memory of the Echo 6 repeater:
a. Make sure the Repeater Operating Mode switch is in
the OFF position.
b. Hold the UP and DOWN buttons simultaneously
c. Turn the Repeater Operating Mode switch to the MON
position.
d. Observe the LCD display. A '*' will appear.
e. Release the UP and DOWN buttons.
f. Turn the Repeater Operating Mode switch to the OFF
position.
g. The memory is now clear. When you turn the unit on
again, Memory Channel 00 will be programmed with the
lowest TX and RX frequencies available in your unit.
NOTE: Before clearing memory, make sure you have a record of
all your operating frequencies that you want to re-program into
the repeater.
