Bt Rush Guest; Create A "Secure" Mesh Communication With Dynamic Repeat - Midland BT RUSH Instruction Manual

BT Rush Guest

In addition to the 10 people talking in a Mesh Conference group, or the 6
people talking in a Dynamic Repeat group, it is possible to add an unlimi-
ted number of BT Rush users only in listening mode (Guest user).
You can follow the same procedure explained in the "BT Rush ID number
Setup" and instead of choosing one of the available numbers, you must
choose "Mesh guest". The voice "Mesh guest" is available either at the end
or at the beginning of the number list.
Create a "secure" Mesh communication with
Dynamic Repeat
If you want to be sure that nobody else will be able to enter your Mesh
Dynamic Repeat group communication, you need to follow a specific
pairing procedure to exchange a "secure key" to all units in the Dynamic
Repeat group.
As first step you need to define one unit as "Master". This is the unit that
will generate the "key" and distribute it to all other users of the group.
It is not important which is the master unit , it can be any unit in the group.
After the pairing procedure is done, all units will share the same "key".
1. Turn off all units of the group.
2. Take the unit one by one and press and hold down the Control button
about 7 sec., until the Red light is on permanently in all the units.
3. On the unit you choose as "Master" press for 6 seconds the Control
button, the Green lights will flash SLOWLY.
4. Now take all the other units of the group, press for 3 seconds the Con-
trol button, the Green and Blue lights will flash FAST.
5. The Master unit and all other units in range (10m distance) will now
exchange the "key". When the procedure is finished, the user unit will
exit the pairing mode and go back to Red light. If you have no other
pairing to do (like phone or GPS) you can make a double click on the
Control button to exit and go to working mode (Blue LED flashing).
6. The master unit will keep blinking Green, in case other units need to
be paired.
7. If no more unit needs the pairing, just make a double click on Control
button of the Master unit to exit the pairing procedure, the Red light
will be on permanently. Make a double click again on the Control but-
ton to exit and go to working mode (Blue LED flashing).
When the pairing procedure is finished and the "Secure" group is crea-
ted, there is no need of the "Master" unit anymore, so it can be part of
the group or missing (turned off) and the Dynamic Repeat group can still
work.

Only the units in the "Dynamic Repeat" mode that share the same " se-
cure key" can talk together.
Other units "out of the box" can NOT be part of this "Secure" group any-
more, unless you pair that unit with a "Master" unit as explained below.
How to add a new unit to an existing Dynamic Repeat
secure Mesh group
If you have a new unit which needs to be part of an existing "Dynamic Re-
peat" secure group, just take one unit from the existing secure group (any
unit is good), consider it as a "Master" unit and perform the same pairing
procedure explained above only with the new unit. No need to make the
pairing procedure again with all units in the group.
Attention: the "secure key" is not used (ignored) when you are in Conference
mode.
Reset the "secure" key
If you want to delete the Secure key, for example because you have se-
veral units and you are not sure which key they have, you must perform a
reset and clean up the secure key stored in the unit:
1. Turn off the unit
2. Press and hold down the Control button about 7 sec., until the Red
light is on permanently.
3. Now press the Upward and Downward buttons together for 3 seconds,
the Green lights will turn on steady and then go back to Red light.
4. Now the "Secure" key is deleted.
5. Make a double click on the Control button to exit and go to working
mode (Blue LED flashing).
6. Now you are back to factory default and you don't have a "secure key"
anymore. All units in Dynamic Repeat mode can now talk each other.
