F6 and F6 Express Fetal & Maternal Monitor User Manual Connection of T840 Telemetry System

1. Put the D-Sub convex socket of the signal cable into the D-Sub interface of the monitor.
2. Put the DB15 convex socket of the signal cable into the DB15 interface of the receiver
unit.
CAUTION
1 DECG cable shares the US1 channel with the telemetry system but has higher priority.
Therefore, do not connect the DECG cable to the monitor when using the telemetry
system.
2 Telemetry system and wired transducers are allowed to be connected to the monitor
simultaneously, but the monitor reacts to the wireless signals preferentially. Once the
cordless US transducer is placed in the storing place, the monitor automatically reacts
to the wired transducers.
A7.2 FHR Monitoring with Cordless Transducers
FHR monitoring with cordless transducers:
1) Connect the receiver unit (as introduced in T840 operator’s
manual).
2) Switch on the monitor.
3) Take out the cordless transducers and apply them to the patient.
Refer to T840 operator’s manual and section 7.2.2/7.5.2 of this
manual.
Once the cordless US transducer is taken out of the storing place,
wireless signal indicators are shown in the numeric area of the
monitor. Other symbols have the same meanings as introduced in
chapter 8 and chapter 10.
When the transducers detect the signals, numerics appear in the US1
and TOCO numeric area respectively.
NOTE:
1 If the measurement results from cordless transducers are dubious, wired transducers
should be used and the clinical decision should be made basing on the wired system
output.
2 The T840 telemetry system only provides one FHR channel (US1).
3 When performing underwater monitoring using cordless transducers, signal loss,
interference and TOCO baseline drift may occur. Avoid pulsating water jets to reduce
artificial traces.
4 When the US or TOCO signal loss occurs, the trace becomes broken. It is necessary
to check the signal quality frequently.
