HOW TO MAXIMIZE RANGE
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.
WEARING POSITION ANALYSES:
BINDING PROCEDURE
Note:
Binding needs to be done under minimum radio interference environment,
which means no cellphone, no computer, no Bluetooth, and no electrical
control panel nearby.
After binding, there is NO need to do binding again next time for
the same group, until new radio(s) being added to the group.
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 until the binding for all the units is done. If in
doubt, repeat the entire procedure.
Power off all the units to exit binding mode.
The radios in binding mode cannot communicate.
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.

When worn, always keep the top of the radio upwards and
the front outwards for the best 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:
