INDUSTRY CANADA COMPLIANCE STATEMENT
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a
type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce
potential radio interference to other users, the antenna type and its gain should be so chosen that
the equivalent isotropically radiated power(e.i.r.p.)is not more than that necessary for successful
communication.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner
avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par
Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention des
autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement d’une
communication satisfaisante.
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions: (1)this device may not cause interference, and (2) this device must

SAFETY WARNING!
Don’t hold Yapalong too close to your head when in use.
GET STARTED
1. Be ware that the antenna cover
is purposely pre-bent for impact
prevention
7. To adjust the sound volume,
press UP or DOWN button, repeatedly
if necessary, until desired volume is
reached. To adjust the microphone
sensitivity, while holding down AUX
button, press UP or DOWN button,
repeatedly if necessary until desired
sensitivity is reached. Now Yapalongs
let every member in the group talk
freely and listen at the same time.
8. To turn Yapalong unit off, hold
POWER button 2 seconds until RED
LED flashes 3 times. Then the unit
powers down.
2. The rechargeable Lithium
polymer battery is pre-installed to
comply with the shipping regulations.
For future battery replacement,
make sure the battery connector is
plugged into the socket with the
color of the cables matching the
polarity “Red Black” shown on the
case. For your safety, use only battery
provided by Nautic Devices Inc.
3. Turn Yapalong unit on by holding
down POWER button for 2 seconds
until RED LED turns on.
4. If the AMBER LED blinks every 2
or 5 seconds or there is no LED light
at all, battery needs to be charged.
Plug the adaptor to the wall outlet.
Plug the barrel connector of the
cable into the power charging jack.
Turn off the unit during battery
charging will speed up the charge
time. AMBER LED turns on during
charging and GREEN LED turns on
when battery is fully charged.
5. If RED LED remains on with high
intensity, it means it cannot detect
other group unit due to various
reasons: no group unit powered on;
group unit out of range; unit in
different group (refer to “Binding
Procedure” to do grouping).
6. If RED LED remains on with
normal intensity, it means it has
detected group unit(s). Plug in the
headset as show in the figure. The
unit is now ready to be used with
other powered-on group units.

BINDING PROCEDURE
Note:
1. Binding needs to be done under minimum radio interference environment,
which means no cellphone, no computer, no Bluetooth, and no electrical
control panel nearby.
2. After binding procedure, there is no need to do binding again next time for
the same group.
03
CLOSE BODY BLOCKING
1. placing bodies in between
antennas causes communication
signs being blocked
ANTENNA TOUCHING BODY
2. Human body is mainly water so it
absorbs RF wave. Water absorbs
RF (radio frequency) wave.
06
No close body blocking
No RF absorption
No close body blocking
Partial RF absorption
Partial close body blocking
due to low position
Partial RF absorption
HOW TO MAXIMIZE RANGE
To obtain maximum range is to eliminate blocking obstacles at line of sight.
The range is greatly reduced when the obstacle is very close to the antenna.
We need to avoid the following scenarios:
Total close body blocking
Partial RF absorption
Total close body blocking
Partial RF absorption
WEARING POSITION ANALYSES:
A. BINDING PROCEDURE FOR REGULAR UNITS
1. Power down all units with good batteries installed.
2.
Power up 1st unit until RED LED is solid on. Hold down UP and DOWN
buttons simultaneously for 3 seconds until GREEN and AMBER LEDs begin to
flash alternatively. Release buttons for 5 or more seconds, both LEDs stop
blinking and all 3 LEDs remain solid on.
3. Power up 2nd unit until RED LED is solid on. Hold down UP and DOWN
buttons simultaneously for 3 seconds until GREEN and AMBER LEDs begin to
flash alternatively. Release buttons for 5 or more seconds, both LEDs stop
blinking and only RED and GREEN remain solid on. If AMBER is also on,
restart Binding from Step1.
4. Repeat Step3 for the rest units.
5. Power down all units (incl. the 1st one) in random sequence. Then power up
all units in random sequence. So far Binding is done. If in doubt, repeat the
entire procedure.
B. ORDER FOR BINDING LISTENER UNITS
LISTENER units can be added to existing Yapalong group as listen-only units.
Regardless of the previous grouping state, the entire group has to be bound
again. The binding procedure is the same as the one for REGULAR units.
In addition we need to follow the order below to bind:
1. Set 1st REGULAR into Binding mode.
2. Set 2nd REGULAR into Binding mode.
3. Set all LISTENERs into Binding mode one by one.
4. Set the rest REGULARs into Binding mode one by one.

INSTRUCTION FOR USE
Hold down POWER button
approx. 2 seconds until RED

Out of range indicator. Your unit cannot
receive RF signal from any unit in the
group. Power on other units, or move closer
to each other.
Battery is fully charged.
Battery is being charged.
1st battery low level warning
–Amber light blinks every 5seconds.
2nd battery low level warning
–Amber light blinks every 2seconds.
Then the unit turns off automatically.
After the radio is taken out of range and brought back into range, its
communication to the group will resume automatically. If the communication is
not resumed immediately, as indicated by extra bright red LED light, you may
press POWER button 1-3 seconds on this radio to force the sync. Restart the
radio is also a good way to resume the communication.
MIC sensitivity sets the minimum
level of sound loudness that the
microphone can pick up. The higher
MIC sensitivity is, the slighter sound
is picked up by the microphone.
Yapalong4000 MIC sensitivity is
divided into 5 levels. And the default
level is 4.
It is good practice to lower MIC
sensitivity in a noisy environment so
that other users will not hear so
much background noise.
Press Up/Down and AUX buttons simultaneously to adjust MIC sensitivity.
Be sure not to press AUX button alone, which will mute the radio.
