System Operation
Turn the receiver on by pressing in the Power switch. Do not switch on
the transmitter yet.
The Alert indicator and the LCD window will light up; the normal-
operation LCD display will appear after 1-2 seconds (Fig. D-1). If
any of the bars show in the “RF” bar-graph meter, there may be RF
interference in the area. If this occurs, select another frequency as
explained below. (If the Meter Hold function has been selected, one of
the RF bars will be ashing, indicating the lowest RF level received.)
Selecting/Setting Frequency
Selection of the desired operating frequency is made through the
function menus. It’s usually best to start by setting the receiver’s
frequency, to determine there is no local interference on that frequency.
Then, always make certain to set the transmitter to the receiver’s exact
frequency. The receiver’s unique Digital Tone Lock system squelches
the audio only, permitting any RF energy on the frequency to show on
the “RF” bar-meter.
Note: It is often convenient to start with the factory-default frequency,
if there is no RF energy showing on the RF bar meter.
Using the Automatic Scan Function to Set Receiver Frequency
1. Press the Mode/Set button once; then the “RF” and “AF” scales will
disappear from the window and only the frequency will appear in
the LCD window. (The receiver is now in the Menu mode.) See
Figure D-2.
2. Use the Up arrow button to reach Group 1 through Group 9. Press
the Mode/Set button once to select one of these nine scan groups.
The lowest frequency in the selected scan group will appear in the
LCD window.
3. Press the Up arrow button to begin the scan. “G SCAN” will ash in
the LCD window.
4. The rst available frequency will ash in the LCD window. To
activate this frequency selection, press and hold the Mode/Set
button until the word “STORED” appears in the LCD window. (If you
do not wish to complete this particular selection, just press the
Mode/Set button once. The word “ESCAPE” will appear briey in
the window and the receiver will return to the Menu mode.)
5. After you have activated your frequency selection (step 4), the “RF”
and “AF” scales will reappear in the window, indicating the return to
normal operation.
6. If you are using multiple systems, all frequencies must be selected
from the same group (Group 1 through Group 9). After completing
the rst receiver’s scan and frequency selection, set the transmitter
to the same frequency (see Setting Transmitter Frequency
instructions); leave the transmitter On, and run the next
receiver’s automatic scan function. Always set a receiver-transmitter
pair to the same frequency before using the automatic scan function
to select a frequency for the next receiver. “End” will show on
the receiver display when no further usable frequencies remain in
the selected scan plan.
NOTES ON USING THE RECEIVER SCAN FEATURE:
• Selecting low power on your transmitter can be helpful for multiple
system setup, if you are experiencing problems with radio
frequency interference.
• To prevent raised noise oors that a receiver scan might interpret as
radio frequency interference: during setup, keep all transmitters at
least three feet apart and at least 15 feet from the receivers.
Setting Receiver Frequency Manually
1. Press the Mode/Set button once; then only the frequency will
appear in the LCD window. (The receiver is now in the Menu mode.)
See Figure D-2.
2. Press the Mode/Set button again; the Alert light will come on and
the rst three digits of the frequency will ash in the window.
(The receiver is now in the Edit mode, Fig. D-3.)
3. Use the Up/Down arrow buttons to change the rst three digits
(MHz) to the desired frequency. Choose a frequency appropriate
for your area, avoiding frequencies with active TV channels. Press
either arrow for single steps, or hold down either arrow for rapid
cycling through the band. Frequencies “wrap around” to the other
end of the range when the top or bottom of the band is reached.
4. Press the Mode/Set button once to set the rst three digits to the
desired frequency.
5. Use the Up/Down arrow buttons to change the second three digits
(kHz) to the desired frequency. Again, be certain to choose a
frequency appropriate for your area, avoiding frequencies with active
TV channels.
6. To activate this frequency selection, press and hold the Mode/Set
button until the word “STORED” appears in the receiver’s window.
(If you do not wish to complete this particular selection, just press
the Mode/Set button once. The word “ESCAPE” will appear briey
in the window and the receiver will return to the Menu mode.)
7. When nished entering a frequency, press the Down arrow button
once to move to “QUIT”. Then press the Mode/Set button once to
exit the menu. The “RF” and “AF” scales will reappear in the
window, indicating the return to normal operation.
Transmitter On…
Turn on the transmitter by pressing and holding the Power/Mute button
(Fig. E/F) for a second or two, until the green power indicator and the
LCD window have come on.

Setting Transmitter Frequency
1. Press the Set button once and the small word “MENU” will appear
above the frequency. Press the Set button again and the small
ashing word “EDIT” will appear to the right of “MENU”. See
Figures M-3 and M-4.
2. Use the Up/Down arrow buttons to change the rst three digits of
the transmitter frequency. Press either arrow for single steps, or
hold down either arrow for rapid cycling through the range.
Frequencies “wrap around” when the top or bottom of the band is
reached. Select the exact frequency displayed on the receiver.
3. Press the Set button once to set the rst three digits to the desired
frequency.
