SETUP
2.9 Group Check
Single Group Check
Before a party takes off, the transceivers of all party
members must be checked. To conduct this test,
the function group check is activated on a single
transceiver within the party. Activate the group
check by switching the device from OFF to SEND
and pressing either of the keys within the first 5
seconds. After a few seconds, the device will auto-
matically activate the group check. Make sure all
the other transceivers of the party are in SEND
mode.
The test is successful if you can clearly hear beep
sounds from each participant's transceiver within
the range indicated on the display. The members of
the party must be spread out appropriately to avoid
mutual interference. The indicated test distance
must not be shortened, as otherwise the group
check becomes very unreliable.
If no tone is heard within the indicated range,
the device may not be used.
How to solve the problem:
1.Check if the device is switched to SEND.
2.Replace the batteries.
3.Have the device checked by the manufacturer.
(chapter «Maintenance and Repair»)
After 5 minutes in group check, the transceiver
automatically switches to the SEND mode. The user
is warned ahead of time by an acoustic alarm. This
automatic switching can be prevented by pressing
any button within 20 seconds. After the group
check, the transceiver must be switched to the
SEND mode by pressing the lateral key.
If your ELEMENT Barryvox ® detects that the trans-
mit frequency of the tested device is not within the
normative regulations, an «E6» warning message
will be shown. In this case, repeat the test with 5 m
distance between the participants to identify the
defective transmitter. Such devices must be
checked/repaired by the manufacturer.

Double Group Check
We recommend to perform a double group check
ones a week and in general when a new group gets
together.
The double group check individually tests the SEND
and SEARCH function of all devices.
The members of the party activate the group check
on their transceivers or set them to a low receive
volume. The leader switches his or her transceiver
to the SEND mode and ensures that all party mem-
bers can receive. Subsequently, the party members
switch their transceivers to SEND, and the leader
activates the group check or sets the transceiver to
a low receive volume. The SEND mode of all trans-
ceivers is checked, and ultimately the leader
switches his or her transceiver to SEND.
