12.1 General Problems
The following table lists the problems that are likely to occur. If the problem persists after
corrective actions have been taken, contact your service personnel.
12.1.1 Troubleshooting Tools
■ Telemetry Receiver (RC60)
■ TD60
■ Central Station (CS)
12.1.2 Problem List
Symptom Possible cause Solution
No RF Signal (The RC60
does not receive valid
data for consecutive 5
seconds)
1. The TD60 battery charge is to be
depleted.
2. The patient is out of the antenna
array coverage area.
3. The TD60 is not connected with
the ECG leadwire.
1. Check if the TD60 battery charge
is depleted.
2. Check if the patient is out of the
coverage area.
3. Check if the TD60 is connected
with the ECG leadwire properly.
RF Interference (The
TD60 receives three
consecutive wrong
frames.)
The TD60 signal is weak. Check if the Patient is at the edge of the
coverage area or in an elevator. Remove
behind a reinforced concrete wall.
SpO
2
No Pulse The SpO
2
sensor failed to obtain pulse
signal.
Check the patient’s condition and
change the sensor application site. If
the error persists, replace the sensor.
The CS does not
display the SpO
2
data.
1. The SpO
2
module is not con-
nected to the TD60.
2. There may be error in the SpO
2
module.
1. Connect the SpO
2
module to the
TD60.
2. If there is an error in the SpO
2
module, replace the SpO
2
mod-
ule with a new one.
ECG noise ECG waveforms are overlapped with the
noise interference.
Check if the ECG leadwire is intertwined
with cables of other devices.
ECG Signal Saturated The TD60 detects that ECG signal
saturation or overload.
1. Check if patient has excessive
movement.
2. Check if the electrodes are in
good contact with the skin.
3. Check if the electrodes operat-
ing time is over the electrode
service life.
Wrong Channel The configured frequency of the
transmitter does not match the
channel.
Reconfigure the frequency of the
transmitter to match the channel.
