4. The total number of bad data packets including missed packets and CRC
errors. Missed packets are described as when a data packet is expected,
but is not recognized as a data packet by the console.
5. Percentage of good packets received.
6. Total number of good packets received.
7. Number of times the console resynchronized with the transmitter. The
console will attempt to resynchronize with the station after 20 consecutive
bad packets.
8. Maximum number of bad packets in a row without resynchronization.
9. Current streak of consecutive bad packets. The counter increments when
the console is synchronized but the packet is bad. This value is reset to
zero when a good packet is received.
10. Longest streak of consecutive good packets received.
11. Current streak of consecutive good packets received.
12. Graph of the daily percentage of good data packets received over the last
24 days.
13. Background noise level. This refers to the undesirable signal level the
console hears while it is in the process of acquiring a signal from a station.
The range displayed is from 5 to 60. When the noise level is high, try to
move the console closer to the station to get a stronger signal. Small
background noise level does not always guarantee good reception. The
signal strength between the station and the console needs to be stronger
than the background noise level in order for the console to receive clearly.
If there are reception problems while a small background noise level is
still being displayed, make sure the console is within reasonable range of
the station.
If the console currently has acquired all the station signals it is set to
receive, the background noise level displayed is the last noise level
measurement taken before acquisition finished.
Note: Receiver Gain Status is an alternate view that is displayed for consoles with firmware versions of
May 2005, or Version 1.6 or earlier. For consoles in which background noise level displays, the
receiver gain is automatically adjusted to obtain the best sensitivity and does not need to be con-
trolled manually.
Alternate View: Receiver Gain Status. Some versions of the console
display receiver gain status and not background noise level. The Receiver
Gain setting provides control over the receiver sensitivity. Press HI/LOW
to toggle Gain on and off. If you're having trouble with reception, try
changing the Gain. Note that Gain can adversely affect performance
depending upon conditions. If you are having reception problems, you
should try both settings. Gain should generally not be turned on when
signal strength is above 30. See Value 4 on page 40 for more information
on signal strength.
