Security Enable page
SecurOff
Page purpose:
This page enables/disables the automatic creation of a random security code every time it boots
up.
Parameters:
[
Off
] / [
On
]
This prevents the user from having to make one up every time (if the user wants a really secure wireless system).
The user has to program this code into the associated transmitter. As always, the receiver will continue to work
with a transmitter that is set to 000:000.
Antenna Signal Strength page
a00 b00
Page purpose:
This page is used to diagnose antenna connection problems.
It displays the signal strength of each antenna in dB. Under normal circumstances, they should be approximately
the same number.
VCO page
vco1.60v
Page purpose:
This page is used to tune and debug the receiver’s RF voltage controlled oscillator.
It should be about
1
.
5
volts while receiving a valid signal. The meter’s range is
0
to
3
.
3
volts.
Reception Error Counters page
Ea000000
Page purpose:
This page displays the reception error counters.
The first three digits are the errors detected from antenna A; the last 3 digits are those from antenna B. The
single letter (character #2) increments every time both channel A and channel B have an error on the same block
of audio. If the letter increments, both channels had a problem with that block and the audio was received
damaged. If the letter does not increment, the audio is being received without errors.
Signal Reception Quality page
s77
▄
▄
v00
Page purpose:
This page displays how well the signal is being received.
The first two numbers represent the signal quality for channels A & B, as do the 2 meters. The letter "V" cycles
through the alphabet whenever an uncorrectable audio error has occurred. The other 2 digits each increment
when an error has occured on channel A or B respectively.
