2008T Machine Operator's Manual P/N 490122 Rev N
Function
Electrically isolated RS 232 serial interface connector; hard wired, used
for display terminal connection.
Used to adjust the volume (sound pressure level) of the dialysis machine
audible warnings and alarms. Warning sound is adjustable between 75
dBA and 89 dBA (at 1 meter). Alarm sound is adjustable between 67 dBA
and 81 dBA (at 1 meter). Does not affect the volume from the separate
CDX speaker.
The Dialysis Mode speaker makes two different sounds: a warning
sound, and an alarm sound. The two sounds are distinct; the first one is
used for lower priority alarms, and the second for more important alarms.
This displays the number of hours the machine has run over its lifetime.
