A. Volume
The Volume allows for adjustment of the beep and/or audio. When this item is highlighted and the FN
key pressed, the following display appears:
Volume selection is accomplished by using the UP/DN keys to select the
desired volume. Choices are 0 to 9. 0 is the quietest and 9 is the loudest
setting. After each adjustment the receiver will provide a short beep
representative of the volume level selected if beep is enabled. Note: The
values do not wrap around from 9 to 0 or 0 to 9. When the desired volume
is reached, pressing the FN key will program this value in the receiver and
return the user to the Main Screen.

B. Diagnostics
The Diagnostics mode provides the display of diagnostic information. This information is contained in
additional screens that are appended to the end of the standard display screens. Information contained
in the diagnostics is as follows:
1) Carrier time (measured time of the 160 ms pure carrier transmitted at the beginning of the
transmission.)
2) Frequency of the received transmission in Megahertz.
3) Power measurement of the received signal in db in the receive mode and dbm or watts when in the
power measure mode. The power in dbm or watts is only meaningful when the PTT unit is directly
connected/wired to the TSUR-400. Be sure to put the TSUR-400 in
RF Pwr
mode before directly
connecting it to a transmitter. You may damage the TSUR-400 if you directly connect a transmitter
while it is in receive mode.
4) Comparison of the number of data groups the message should contain with the number actually
received.
5) HEX display of the first seven data bytes transmitted. (These bytes contain sync, format,
initialization, data groups and parity information.) When this feature is highlighted and the FN key
pressed, the Diagnostics are toggled between ‘ON” or “OFF”. When Diagnostics is selected “DG”
appears on the right side of the bottom line on the main screen.
C. Split
Please see Split Setup under the Menu Level 2 setup for additional explanations. The “Split” feature is
selected through this operational parameter. When the FN key is pressed, the “split” function is
toggled between “ON” and “OFF”. When “split” is programmed “ON” the main screen Level 1 will
display “SPLIT” in the middle of the bottom line.
D. Update
The “Update” feature is selected through this operational parameter. When the FN key is pressed, the
“update” function is toggled between “ON” and “OFF”. When “update” is “ON”, the receiver will
update the main screen with the new data being received. If the user is viewing previous received
messages with “update ON” and a new message is received, the screen will change to display the new
received message. If update is “OFF” then the main screen is not updated when a new message is
received, and if the user is viewing previous received messages the screen will continue to display the
pages being viewed.
