2 When the supply mains are interrupted, the device switches to internal power supply
and operates normally if the battery is installed. If the battery is not installed, the
system shuts down and resumes the previous settings at the subsequent operation.
3 After the AC power supply is connected, please wait for at least 2 seconds before
pressing the POWER switch to turn on the system.
3.2.5 Configuration
The system can support, at most, 2 US-T transducers and 1 TOCO-T transducer, 2 US-T
transducers and 1 TOCO-E transducer (DECG and MHR not enabled), 1 US-T transducer and 1
TOCO-E transducer connected with DECG cable, or 2 US-T transducers and 1 TOCO-E
transducer connected with MECG cable. Please do not exceed the maximum number.
NOTE:
1. If the system is provided with transducer protection cover, please do not take up
the cover during monitoring.
2. The TOCO-T transducer and the TOCO-E transducer cannot be used
simultaneously.
3. When DECG is enabled, only US2 channel can be used for the US-T transducer.
If one FHR is monitored by wired DECG and the other FHR is to be monitored by
wireless US-T transducer, take up one US-T transducer, which will display “US1”,
and then wait for 2 seconds to take up the other US-T transducer. When the second
US-T transducer connects successfully and displays “US2”, fix it on the location
where the best fetal heart signal is received, and put the first US-T transducer back
in the docking slot.
3.2.6 Connecting to the Monitor
Use the DB15 interface cable (01.13.036299) to connect the FTS-3 system to the monitor. Then
switch on the monitor and the FTS-3 system.
If the monitor is connected to the MFM-CNS Central Monitoring System, use the Y-shaped DB9
interface cable (01.13.036301) to connect the monitor and the FTS-3 system.
3.2.7 Adjusting the Working Channel
If the fetal heart sound is with interference or it cannot be played smoothly, the working channel
is probably interfered. Put all the transducers back in the docking slots and press the adjustment
button in back of the base station. The channel range is 1-14.
Restart the system when it enters the charging interface.
