7.3.4 Changing DECG Beep Volume
When the DECG beep is enabled, the monitor gives a beep sound of DECG.
To change the DECG beep volume,
1 Select the setup key
on the main interface.
2 Select Fetus > DECG Beep.
3 Select 0 (default) ~ 9.
4 Select OK.
NOTE:
1 The DECG beep and HR beep share the same audio channel. Once the DECG beep
is switched on, the HR beep is disabled (set to level 0) automatically.
2 Once the DECG/HR beep volume is changed, the sound switches to channel 1
automatically. Therefore, it is advised against changing DECG/HR beep volume in the
monitoring process.
7.3.5 Switching the Artifact Suppression On or Off
When monitoring FHR with DECG, artifacts may occur due to bad connection of the spiral
electrode, excessive motion of the mother, electromyographic interference etc.. The Artifact
Suppression feature is designed to eliminate the interference. When artifact suppression is on,
artifacts are suppressed and not recorded. When it is off, the artifacts are shown as well as the
fetal heartbeats.
You can choose to switch the artifact suppression on or off.
1 Select the setup key
on the main interface.
2 Select Fetus > Artifact Suppression.
3 Select ON (default) or OFF.

WARNING
When artifact suppression is on, fetal arrhythmia will also be suppressed. Therefore, if
fetal arrhythmia is suspected, switch artifact suppression off.
