• Do not release the button, keep it pressed for another 3 seconds. Finally You will see an
alternating flashing of the red and green LED’s.
Now Your adapter has entered the pairing mode and is searching for other bluetooth devices nearby, like Your
headset. You will have about 45 seconds time to start the appropriate pairing procedure at the Headset, too.
Starting Pairing Mode of Headset
The pairing mode of the Headset is described in the user manual of Your headset. Please follow the user
instructions. Most headsets show the pairing mode by a faster flashing of LED’s. As soon as both devices
have found each other, the fast flashing will stop. Both systems remain automatically in their standby modes.
Note: some more intelligent headsets or handsfree systems may ask for a security code of the adapter. If
such a note appears in the display (if equipped), please use 1234 as code for the adapter.
Connecting the 2 way Radio and starting Conversation Mode
• Connect the radio cable to the 2 way radio’s 2.5/3.5 mm
mic/earphone socket. connect adapter and PTT button as
indicated. Switch radio on and adjust to medium volume. Please
avoid to place the adapter too near to the radio’s antenna!
• After pairing the adapter is in standby mode (green LED is
flashing every 2 seconds).
• Switch the headset from standby mode to “Call” or “Talk”. In
the user manual this is described as starting a phone
conversation. In most cases You will find a “Talk” button.
• Starting and stopping the communication link will be done at the
headset side. As long as You need the radio communication
(including the receive periods!) the headset must stay in the
„Talk“ or „Call“ position, whatever the user manual describes.
Please note that the user manual describes telephone
conversation and not a 2-way radio conversation.
• Start the connection to Your 2-way radio by using the Talk / Call button of the Bluetooth
TM
headset.
It will always take a small moment, until You can see that the communication link is established. You
will see the green LED on the adapter side permanently on. This demonstrates, that connection is
successful.
• Adjust the headset volume at first to minimum to avoid any risk of acoustical shock. Open the
squelch of the radio for testing (or press the monitor button). You will hear the white noise from the 2
way radio. You may now adjust the volume at the headset according to Your needs. Do not adjust
the volume of the radio too loud, this may provide distortion.
• To talk via radio press the PTT key on the radio’s side (which You have probably mounted at the
handle bar of a motor bike or at other suitable places) and talk via Your headset.
• To receive again, You release the PTT key again. Please do not switch anything at the headset side!
• If You do not want to listen any more to Your radio channel, You should disconnect the
connection from the headset side only (Talk or Call button). The adapter at the radio side will
then automatically switch back to standby mode.
• Please switch both devices completely off, when You do not need them.
Important notes explaining different characteristics of radio and cellular phone
When using cellular phones, You only need to use the Talk/Call button of Your headset when You start a
phone call or answer a phone call. In receive mode of a two-way-radio, You must ensure, that at any time
incoming audio from other stations can be transmitted to the headset side. So the headset side must always
remain switched into Talk/Call mode, or You cannot hear what happens on the radio channel!
A PTT key is necessary in 2-way-radio communications, because many users share a common channel-
