4.4.5.5.2 Modulated Carrier
Test transmission generates a carrier modulated
with 1kHz sinewave, at deviation level that de-
pends on model and network speed:

This function is frequently used for checking
frequency deviation.
Press the TXON (Modulated) button to begin
transmitting a 20-seconds modulated test signal
on the channel or until the button is pressed
again.
The functions of all the other buttons are inop-
erative during test transmissions.
4.4.5.6 Ping Button
The Ping function checks connectivity by testing
the ability of Gemini
PD
to communicate with the
base station by sending a short transmission
query and receiving a confirming response.
1- Specify the channel (paragraph 4.4.5.3) and
ping address (paragraph 4.4.5.7)
2- Press the Ping button to start ping testing.
The functions of all the other buttons are inop-
erative during pinging.
The program sends a test query and continues
transmitting pings at brief intervals.
As soon as a Ping test signal is returned from the
address selected, the status bar displays:
•
“Ping Successful” and pinging stops.
•
If no ping signal is received after 60 sec-
onds, ping testing stops and the status bar
displays “Ping Failed”.
4.4.5.7 Ping addresses
Addresses may be entered by typing directly in
the “Ping Address” field in two ways:
1. Numerically, the valid address range is
1-126.
2. As an “Alpha-Mapped-Nibble” (AMN) ad-
dress, consisting of upper case letters in the
range A-P. The valid address range is A to
GN.
The base address is usually: 1.
The program may display one of the following
messages on the status bar:
For Paragon
PD
product:
“Ping address is not in AMN or number format”
or
For Gemini
PD
product:
“Ping address is not in the range A – GN”
In either case, check that the address entered is
within the acceptable range, is of a valid format
and correctly typed.
4.4.6 Status Bar
The Status Bar is located along the bottom edge
of the WinRIS window. To display or hide the
bar, check or uncheck the command in the
“View” menu.
The left area of the status bar describes actions
of menu items as you navigate using the direc-
tional arrows. This area also shows messages
describing actions of toolbar buttons as you de-
press them, before releasing them. If after
