User Manual

consecutively. Pressing the down button when the
lowest channel number is displayed will cause the
channel selection to wrap around to the highest
available channel if the channel wrap parameter is
set.
Holding the channel up or down button depressed
will cause the channel numbers to scroll with a
system defined start-up delay, and subsequent
smaller delay between each change in channel
position. These delays are set using system
parameters.
On power-up the channel number will be either the
system global power up setting or a locally saved
power-up channel or floor channel if a locally saved
channel number is outside the valid channel
numbers.
Volume Control
Volume control is done using the volume up and
volume down buttons. The number of volume levels
and the step size in dB between successive levels is
globally defined using system parameters –
however setting the volume level to 0 turns the
headphone/line output off.
When a volume button is depressed the channel
display will be overridden with the current volume
(this is indicated by the black dot in the upper left
corner of the display) if the show volume global
parameter is set. The display will continue to show
the current volume level for a preset time interval
before returning to displaying the channel
information – this time interval is also set globally
using a system parameter.
The audio can be attenuated on all interpreted
channels, when no interpretation is performed and
floor is present on the channel. This feature can be
used when the channel selector is used in
combination with an analogue microphone system
to prevent feed-back from the channel selector to
the microphone if the delegate is speaking and
listening to the same channel. The attenuation in dB
is set globally – however enabling or disabling this
feature can be set individually on the channel
selectors.
Storing local setup in FLASH
If enabled by the central unit the channel selectors
may store the following local parameters in flash
memory thus overriding the global system settings
•
start-up volume level
•
startup channel number
•
attenuate floor audio on interpreted channel
To change the local setup in flash memory this must
be globally enabled from the CU.
To set a new startup volume level use the volume
up or down button to change to the wanted
volume level and then depress both channel up
and channel down buttons. After a short time
period the display will show
F1 –
if the buttons
are released while the display is showing
F1
the
display will change to
FP
to indicate that the new
value is now programmed into flash memory. To
clear the locally saved volume level position
depress both channel up and channel down
buttons until the display shows
C1
then release
the buttons – the display will then change to
FC
to indicate that the flash is cleared of this setting.
To set a new start up channel position use the
channel up or down button to change to the
wanted channel position and then depress both
volume up and volume down buttons. After a
short time period the display will show
F2
– if
the buttons are released while the display is
showing
F2
the display will change to
FP
to
indicate that the new value is now programmed
into flash memory. To clear the locally saved
start up channel position depress both volume up
and down buttons until the display shows
C2
then release the buttons – the display will then
change to
FC
to indicate that the flash is cleared
of this setting.
To activate the attenuate floor audio on
interpreted channel functionality of a unit
depress the volume down and channel up
buttons. After a short time period the display will
show
F4
– if the buttons are released while the
display is showing
F4
the display will change to
FP
indicating that the activation is now saved to
flash. To deactivate the attenuate floor audio on
interpreted channel functionality of a unit
depress the volume down and channel up
buttons until the display shows
C4
then release
the buttons – the display will then change to
FC
to indicate that the activation is now cleared from
flash.
Startup / Error conditions
The following conditions in addition to the
channel number are displayed:
•
E0-E4, network error
•
E5, network error or firmware mismatch
•
E9, reset
The channel selector will always show E1 shortly
when powering up, then the display will change
to show the channel number.
If any of the “E0-E5” messages is shown
constantly, please check your cables and verify
that the terminator plug is inserted in the last
unit in the chain.
