ON Sound siren on emergency ANI.
5.6.1.4 Internal Speaker setting
Normally, the internal speaker is on and audio from
the radio can be heard. If this is not desired, change
this setting to OFF. The enabled beep features can still
be heard however. If it is desired that absolutely no
sound be heard from the console speaker, simply
disconnect it.
OFF Internal speaker disabled.
ON Internal speaker enabled.
5.6.1.5 Auto Mute Speaker feature
This feature is designed to mute the internal speaker
while an ANI is being received. It works in conjunction
with the Auto Mute Time. When this feature is
enabled, the internal speaker remains muted so long
as there is no COR indication coming from the radio.
When the COR indication goes active, the internal
speaker will automatically unmute after the Auto Mute
Time expires. Note: System sounds can still be heard
during the mute period.
OFF Do not mute the internal speaker.
ON Mute/unmute speaker automatically.
5.6.1.6 Auto Mute Time setting
This is used in conjunction with the Auto Mute
Speaker feature. This specifies how long the DDU
internal speaker will remain muted after the COR input
goes active. This value should be set to allow for any
key-up delay of the transmitting unit as well as the
time it takes for the ANI to complete.
Range: 0000 to 4000 milliseconds
Default: 0600 milliseconds
5.6.2 TIME SETUP menu
In order for the correct time to be displayed, the time
clock must be set. The unit must remain switched-on
at all times in order to keep track of the time. The
clock must be set each time the unit is powered up.
5.6.2.1 Hour setting
Set the hour of the day in 24-hour format. Enter two
digits.
Range: 00-23
Default: 00
5.6.2.2 Minute setting
Set the minutes past the hour. Enter two digits.
Range: 00-59
Default: 00
5.6.3 CONSOLE SETUP menu
5.6.3.1 Data Entry Mode setting
Determines if numeric entry or alphanumeric data
entry is the default mode when selecting a record. The
mode of entry can be toggled by pressing the <*> key
during data entry (except when entering ANI's).
NUMERIC Start in numeric only mode.
ALPHA Start entry in alphanumeric mode.
5.6.3.2 Ignore Nonuser option
Turning on this option helps prevent the display of
false decodes by ignoring ID’s which do not appear in
the user database. This can also be used to restrict
access to a repeater to only those ID’s in the database.
See REPEATER SETUP for more information.
OFF Display ID’s not in database.
ON Ignore ID’s not in database.
5.6.3.3 Fast Scrolling setting
Fast Scrolling allows for faster navigation through the
menu system. The DDU can also animate the scrolling
of the screen from side-to-side. This provides positive
feedback in response to scrolling through menus and
the ANI log. If this effect is desired, Fast Scrolling can
be disabled.
OFF Animate scrolling from side to side.
ON Scroll at fast speed.
5.6.3.4 Contrast setting
Allows the display contrast to be adjusted for best
viewing.
LOW Low contrast setting.
HIGH High contrast setting.
5.6.3.5 Mic. Option setting
Selects which type of optional microphone accessory
is attached to the DDU. This is necessary so that the
DDU knows how to treat the external signals.
NONE No microphone.
GOOSENECK Gooseneck style microphone.
PADDLE Paddle style desktop microphone.
HANDSET External handset.
5.6.3.6 Printer Option
The DDU, if ordered with the printer cable option, can
log the ANI traffic to a serial printer. The printer must
have a print buffer and a standard RS-232 port. It must
be configured for 9600 baud, 8 data bits, 1 stop bit and
no parity. In order to send data to the printer, this
