System track erase
<spi prefix> + <03*nn>
default
13003*nn

before rerecording.

Search tracks
The search tracks formats are used to sequentially play a range of system tracks. The DVR starts at
track# <nn> (or track# 00 if <nn> is omitted) and sends the track number followed by a playback
of the track for each of the remaining tracks. This format is useful for locating a track if the
number has been forgotten. The search continues until a COS is detected or until the last recorded
track is encountered (blank tracks are skipped). The search long function plays each track in its
entirety, while the search short only plays the first 1 second of each track.
LOPSTART A
<spi prefix> + <050> ; <nnn>
Start lop-off: input A (milliseconds)
LOPEND A
<spi prefix> + <051> ; <nnn>
Stop lop-off: input A (milliseconds)
LOPSTART B
<spi prefix> + <050*> ; <nnn>
Start lop-off: input B (milliseconds)
LOPEND B
<spi prefix> + <051*> ; <nnn>
Stop lop-off: input B (milliseconds)
default
130050nnn
Start, input A
130051nnn
Stop, input A
130050*nnn
Start, input B
130051*nnn
Stop, input B
The "lop-off" values are the amount of time that subtracted from the beginning or end of each
recorded track. This allows the elimination of switching and squelch noise from the beginning
and/or end of tracks which gives a "clean finish" to the DVR tracks. If the system has a long
squelch burst, or some other artifact that is heard at the beginning and/or end of a recorded track,
then these values may be increased to remove the particular artifact. NOTE: it is not necessary to
rerecord tracks for new lop-off values to take affect, this value is used in play-back only, so the
values may be changed any number of times without altering the original track recordings.
LOPSTART A and LOPEND A affect all tracks recorded from the "A" input while
LOPSTART B and LOPEND B affect all tracks recorded from the "B" input. The Audio Test
track does not use the lop-off functions, so squelch noises or DTMF "blips" observed on this track
are normal.
