Notice:
The changes or modifications not expressly approved by the party responsible for compliance could void the user’ s authority
to operate the equipment.
FCC INFORMATION
The Federal Communication Commission Radio Frequency Interference Statement includes the following paragraph:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
The equipment has been tested and found to comply with the limits for a Class B Digital Device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction,
may cause harmful interference to radio communication.
However, there is no grantee that interference will not occur in a particular installation. If this equipment dose cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
IMPORTANT NOTE:
To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the
antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device.
Consumer Alert
Most users do not need a license to operate this wireless microphone system.
Nevertheless, operating this microphone system without a license is subject to certain restrictions:
The system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no
protection from interference received from any other device.
Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to
change.
For more information, call the FCC at 1–888–CALL–FCC (TTY: 1–888–TELL–FCC) or visit the FCC's wireless microphone Web site at

Setup Procedure
Signal Connections
1. Connect 6.3 mm mic jack from “Unbalanced AF Output” to amplifier’s “MIC IN”
and set “impedance” at “LOW”. Or connect 6.3 mm mic jack from “unbalanced
AF Output” to amplifier’s “LINE IN” and set “impedance” at “HI”. (The same
way can be applied in EJ-701DR-PLUS / EJ-702DR-PLUS.)
Amplifier
2. If using XLR mic jack, connect it from
”Balanced AF Output” to amplifier’s “AUX IN”.
In order to prevent from the impedance from being too high thus producing
unexpected noise, please set “impedance” at "LOW” if you are connecting
a mic jack to a “low input” in the subordinate device.
3
If your subordinate device is with general input socket (e.g., LINE IN, AUX IN
, etc), please set ”impedance” at “HI” to avoid too low-volume output.
AF Impedance Selection (HI / LOW Control)
Remark: AF Impedance Selection only controls
Unbalanced AF Output (6.3 mm jack).

Turn “Receiver power on/off control” knob (7) clockwise until a click occurs.
A text of “ ” will appear on LCD window for about 2 seconds and it
follows a channel number. The turning-on is successful. To turn it off, just turn
the control counterclockwise until a click occurs. A text of “ ” will appear
on LCD window and will disappear after 2 to 3 seconds.
Press and hold “Up or Down” button (6) for 1 second until channel number is
blinking. Select a desired number through “Up or Down” button (6). A selected
channel number will be confirmed in 1 second if no more adjustment made to it.
Change channel manually
How SYNC works
“ ” function can find a clean channel and assign it to transmitter in the
range, about 3 M. Just turn on your microphone or transmitter first and press
SYNC button, in few seconds the progress will be done. During synchronization,
the RF indicator will blink.
Please complete channel setup in one receiver first and then a second one
when you have more than 1 receiver.
Be sure to give different channel number to each receiver.

CAUTION!!
Take out batteries when the devices won’t be operated in a long time.
DO NOT attempt to charge Alkaline battery. It will lead to battery
leakage or even explosion!
The performance of signal transmission is highly
involved with battery energy. Batteries with 1600
mAh (or above) in capacity are recommended.
The optional charger HDC-702 / 707 is an economy
solution for your daily use.
Frequency Pairing
1. After turning on the unit, the frequency pairing will be run once within 10 minutes.
The LED Power Indicator will be light on in blue for three times and the backlight
of LCD window will be on as well while frequency pairing successfully. While
changing to a new channel, the LED Power Indicator will be light on in blue
constantly.
2. Press “Frequency Set” key (8) for less than 2 seconds to enable frequency pairing
function again. During the process of frequency pairing, the LED Power Indicator
will be light on in blue blinkingly together with channel number blinkingly
shown on LCD window. If frequency pairing successfully, new channel number will
be shown on LCD window unblinkingly and the LED Power Indicator will be light on
in blue constantly. If frequency pairing unsuccessfully after turning-on for 20
seconds, it will back to the original channel number with LED Power Indicator light
on in blue constantly and the original channel number remained without blinking.
