Soft Sip will be highlighted first. The user must now make a series of soft sips. After each sip, a live readout of the current
pressure will be displayed on the screen in the form of a line within the 0 - 100 scale. Repeated soft sips will produce a ‘band’
of values. During this process it may be beneficial for the user to look away from the screen. This prevents ‘false’ values where
the user may be trying to attain earlier levels. Once you are satisfied that the user can produce a soft sip consistently within
this band, use the right navigate button on the front of the Omni2 to highlight Hard Sip.
The user must now make a series of hard sips to produce a new Hard Sip band. Ideally there should be as much difference as
possible between the Soft Sip and Hard Sip values. To aid the Omni2’s differentiation between these pressures, the installer
should move the Threshold Marker, (shown in the diagram below), to the middle of the gap between the hardest soft
command and the softest hard command. This is done via the + / - buttons on the front of the Omni2. Once a suitable
threshold is set, use the right navigate button on the front of the Omni2 to highlight Soft Puff.
Now repeat the sequence of instructions as above for both soft and hard puffs including the Threshold setting. Once
calibration has been performed, use the right navigate button on the front of the Omni2 to return to the Calibrate option in
the Sip and Puff branch of OBP.
NOTE (HP, IN)
All values must be greater than the Deadband setting, for calibration to be performed successfully.
For further details of the parameter Deadband, refer to the Programming chapter.
8.6 SINGLE SWITCH SCANNER
A single User Switch is connected to the Omni2 via one of the 3.5mm / 1/8” jack sockets.
WARNING (HP, IN)
For a truly fail-safe system, Curtiss-Wright recommend that a User Switch incorporating a resistor network is fitted. If one
of these is unavailable, a normally-closed User Switch should be used. This ensures that if the switch becomes accidentally
disconnected, the powerchair will default to a stop condition. If a normally-open switch is used, the responsibility for that
decision lies with the healthcare professional. Curtiss-Wright accept no liability for any losses resulting from the use of a
normally-open User Switch.
If the Omni2 is configured to operate with a Single Switch Scanner-Type SID, the scan rate can be programmed to suit the
user. Refer to the Programming chapter for further details.
