Battery Back-Up - Invacare CS8 User Manual

3. ELECTRONIC FUNCTIONS – Continued
Chair Positioning
The chair positioning function moves the bed into a foot down tilt position whilst
simultaneously adjusting the backrest and knee section. The foot down tilt range is
between 0° and 14°.
• When using the chair positioning function the mattress platform may initially rise
before tilting. The bed will automatically adjust to ensure there is sufficient clearance
between the mattress platform and the mechanical structure of the bed before tilting.
Press and hold the function button until the desired positioning is reached. The bed
will tilt forward and simultaneously raise the backrest and knee section, providing a
seated upright position.
• Reversing the chair position requires the use of the individual function buttons. To
bring the bed back to level from the foot down tilt position, use the hi-low lower
button followed by the backrest and knee section lower buttons to complete the
process.
Under Bed Lighting
The under bed lighting feature provides a soft LED illumination of the floor beneath the
bed carriage. This safety feature provides floor illumination for patients at night when
getting in and out of bed. In the event the bed is operating on battery power (e.g. during
transport) the lights will power down after approximately 2-3 minutes.
3.2 Battery Back-Up (Optional)
The CS8 bed, if fitted with a battery back-up unit (located beneath the backrest of the
bed) will automatically switch to battery power in the event of a power failure, or the bed
being unplugged from mains power. The period of use on battery is dependent on many
variables. Weight of the user, range of movement used and age of the battery. In good
condition, the battery would allow for a minimum of ten to fifteen full lift cycles.
