SINGLE BUTTON MENU INTERFACE
The MENU system can be
entered from the OPERATING
SCREEN as described in section
3.4 OPERATING SCREEN.
While in the MENU system, every
time the user presses the control
button the CURSOR will move
down
one
line
and
the
COUNTDOWN INDICATOR will be
reset to 5.
Once the CURSOR is pointing at
the desired item the user simply
allows
the
COUNTDOWN
INDICATOR to reach 0 and the
selected item will be executed.
This simple behaviour is used
throughout the menu interface to
modify settings and interact with
the 2405 unit.
3.5.1.
EXIT
The first item on every page of the menu system is EXIT. If no other selection is made then
EXIT is selected by default and the 2405 will exit the menu system and return to the
OPERATING SCREEN.
3.5.2.
MANUAL MODE / AGC MODE
This item toggles between AGC MODE (Automatic Gain Control) and MANUAL MODE gain
control. It is recommended that AGC mode is used during most deployments although in
environments where the background noise level is unstable it can be advantageous to use
MANUAL MODE to prevent the AGC constantly changing gain in response to variations in
background noise levels. See section 3.4 OPERATING SCREEN.
3.5.3.
SET TIME / DATE
This item allows the time and date to be adjusted. Ensure that a valid time is entered in
24hour, HH:MM:SS format and a valid date in DD/MM/YY format.
The digit to be edited is indicated by ‘^^’ below the digit. Press the push button momentarily
until the required value is displayed. Once the correct value for the digit is displayed allow the
countdown timer to expire and the selection arrows will advance to the next digit.
While setting the seconds field the control button can be held down to freeze the current time
to help synchronise with a reference time.
