CAUTION
To avoid unwanted noise, do not take out or place the probe when the main unit is on.
Remember to take out the probe before switching on the main unit, and place the probe
after switching off the main unit.
To switch on the main unit:
Pick up the probe and then press the ON/OFF key on the main unit.
All the real-time examining menu elements light up in a few seconds. A start-up sound (if the key
sound is enabled) is heard. The Doppler performs a self test by displaying the FHR numerics in a
fast speed.
To switch on the wireless probe:
Press the Power key on the wireless probe. The probe indicator lights up in green.
NOTE:
1 For SD6, the Power keys of the wireless probe and the main unit need to be
pressed separately. After they are switched on, they will be connected with each
other automatically, and the LCD will display to indicate normal connection. If
you touch the acoustic faceplate of the probe gently with your hand, the Doppler will
give out sound.
2 For SD6, docking the probe when the main unit is powered on and is in normal
connection with the probe, the probe will turn off automatically and begin to charge.
If you take up the probe within 3 hours, it will power on automatically and be ready
for use.
3 For SD5, the wired probe is ready to use when the main unit is switched on.
3.6 Switching Off
When the examination is finished, switch off the main unit, wipe the remaining gel off the probe
with a clean soft cloth and then place the probe back into the holder.
To switch off the main unit, perform any one of these operations:
1) Press the ON/OFF key on the main unit.
2) Put the probe into the probe holder.
3) Auto shut off. If the main unit does not receive signal for a period of time, it will be
switched off automatically. The auto-shut-off time is preset in the setup menu. Refer to
section 3.8.3 Setting Auto-Shut-Off Time.
