Solution
NMT No Main
Cables
Low
The NMT main cable is
disconnected.
Check the connection between the
main cable and the NMT module.
NMT No Sensor Low
The NMT sensor is
disconnected.
1. Check the connection between the
sensor and the NMT main cable to
ensure normal connection.
2. If the alarm persists, replace the
sensor.
NMT Stimulation
Electrode Off
Low
The NMT stimulation
electrode falls off.
1. Check the connection between the
stimulation cable and the main cable to
ensure normal connection.
2. If the alarm persists, check the
connection between the stimulation
electrode and the patient.
NMT Sensor Comm.
Error
Low
An NMT sensor
communication error
occurs.
1. Check the connection between the
sensor and the NMT main cable to
ensure normal connection.
2. If the alarm persists, replace the
NMT module or sensor.
3. If the problem persists, check the
connection cable between the
backplane and the display.
4. If the problem persists, replace the
module rack (refer to 11.1.14).
5. If the problem persists, replace the
cable between the backplane and
display.
NMT Stimulation
Current Over Limit
Low
The output stimulation
current of the NMT
module exceeds the
limit.
1. Check the connection between the
stimulation cable and the main cable to
ensure normal connection between the
stimulation electrode and the patient.
2. If the alarm persists, replace the
NMT module or related component.
NMT Comm.
Abnormal
High
NMT communication is
abnormal.
1. Re-plug the NMT module, main
cable, sensor, and stimulation
electrode, or plug the NMT module to
another machine. Eliminate the error
situations one by one.
2. If the alarm persists, replace the
