CPR WARNING:
If you or your facility decides to use this chair for CPR purposes, it is only to be performed if the chair has a
LAY FLAT SUPPORT BAR (see Section 3.14) tted to manufacturers’ specications and the bar is at 90 o (degrees) to
the BACKREST and the FLOOR – see following conditions.
In the event you need to perform CPR on a client in this chair you must have fully read and understood everything on
this document and the following must be strictly adhered to;
1. If you have a LAY FLAT SUPPORT BAR – SWINGDOWN STYLE it must be fully engaged FIRST (see Section 3.14 &
Figure 14a)
2. Then fully activate AUTO FLAT SYSTEM (see Section 3.13 & Figure 13).
3. You have assessed the need for a CPR assistance device such as a CPR board which may be required for eective
CPR due to the Pressure Care Seating system in use on this chair. Your clinical team needs to assess this as
the manufacturer provides the chair with multi-positioning outcomes but cannot guarantee or advise on the
eectiveness of the patient outcomes from a CPR event due to a multitude of external factors.

5.2 DESCRIPTION OF THE VARIOUS SIGNS USED IN THIS MANUAL
WARNING!
Failure to comply with these instructions may result in accidents involving serious personal injury.
Failing to follow these instructions can result in the product being damaged or destroyed.
5.3 DO’S and DON’TS - General
DO’S
ü Do plug the chair into mains power and charge the Emergency Battery Back-up system for 24hrs before the 1st use.
ü Do keep the control box plugged into the mains supply whenever possible. This will extend the life of the
Emergency Battery Back-up. A large number of cycles can be obtained from operating solely on the batteries;
however battery lifetime is reduced with frequent discharging.
ü Do inspect all cables particularly the mains power cable for any damage; replace where necessary.
ü Do make sure that the Handset coil cable is always free and not tangled up in the workings of the chair.
ü Do stow the mains power cable and the HB handset when moving or transporting the chair.
ü Do clean the actuators, control box, handset and attendant control panel at regular intervals to remove dust and
dirt.
ü Do maintain the batteries correctly, see Battery Maintenance & Replacement.
DON’TS
û Don’t allow the batteries to fully discharge before connecting to the mains supply. The batteries are a lead-acid gel
cell type that can be trickled charged continuously (batteries used for standby / emergency back-up) and have a
high current discharge capacity. The batteries are not the nickel cadmium type and must not be periodically fully
discharged. Life is greatly reduced by deep or complete discharging of the batteries. The best lifetime is obtained
by charging the batteries as often as possible.
û Don’t continue to operate the handset by repeatedly pressing the buttons if the chair function will not move, or the
actuator will not function. If this occurs then the actuator has either reached its end position, the load is too great
or there is a problem. Refer to troubleshooting guide.
û Don’t exert excessive force on the handset cable as this may break o the wires inside the cable and prevent some
or all of the operations.
û Don’t continually operate the chair functions. The system is not designed as an exercise machine and continuous
operation will cause the thermal fuse in the control box transformer to cut o power to the transformer; the control
box will then require servicing. Refer to the manufacturer’s manual for the specied duty cycle.

5.4 SAFETY INSTRUCTIONS
PLEASE READ THE FOLLOWING SAFETY INFORMATION CAREFULLY. IT IS IMPORTANT FOR EVERYONE WHO IS TO
CONNECT, INSTALL OR USE THE SYSTEMS TO HAVE THE NECESSARY INFORMATION AND ACCESS TO THIS MANUAL.
Classication:
The equipment is not suitable for use in the presence of a ammable anaesthetic mixture with air or with oxygen or
nitrous oxide.
Warning!
The plastic parts in the system cannot tolerate cutting oil.
Warning!
If faults are observed, the products must be replaced.
Never spray directly on the products with a high pressure cleaner.
The LINAK products cannot tolerate the inuence of strong solvents, basic or alkaline liquids.
The duty cycle printed on the label of the control box must always be noted. If this is exceeded, there is a risk of the
control box being overheated and damaged. Unless otherwise specied on the label, the duty cycle is max. 10%: max.
2 minutes in use followed by 18 minutes not in use. Exceeding the duty cycle will result in a dramatic reduction in the
lifespan of the product.

5.5 LINAK OPENBUS™ DO’S and DON’TS
5.5.1 Before connecting or disconnecting OPENBUS™ accessories or handsets to / from the system:
a. Disconnect the CB from mains power.
b. Wait at least 2 minutes after the last key press.
5.5.2 Only connect the originally specied type of Actuator to the appropriate port on the CB.
5.5.3 Only connect the originally specied Handset to the system.
5.5.4 Wait at least 2 minutes after the last key has been pressed before removing the BA18 or BA20 battery from
your system. Otherwise battery operation may be blocked for 30 minutes.
5.5.5 Do not connect / disconnect an Actuator while pressing any keys on the Handset or Foot Switch.
5.5.6 Use O-rings on all connectors (greasing them 1st) and secure all connectors / cables with the cable locking
devices supplied.
5.5.7 Use blind plugs with O-rings to seal any unused ports on the CB and junction boxes.
5.5.8 Do not stretch or unduly strain any of the cables and connectors.
5.5.9 In cases where a CU20 or CP20 requires replacement, in order to avoid damage to new components, replace
the complete CB20, rather than individual components.
5.5.10 Ensure that the system is suitably protected from ESD (Electro Static Discharge) via the ESD drag chain/wire
tted to the base of your chair. If worn out, replace with an original part.
5.5.11 In the event of a breakdown of the chair electric functions, do not diagnose the fault by switching actuators
around between dierent working ports, or use components from a working chair on the faulty chair. This
system is not a ‘Plug and Play’ type. It is computerised and sensitive to faulty parts. A faulty or damaged
component may cause ruin/damage to a working/new component. It is always best to call a technician with a
Linak approved repairer qualication to diagnose the issue, if it is not obvious.
5.5.12 In the event components are replaced, it is always best to perform a Reset and System Initialisation after doing
so, to enable correct function of the chair – refer to 5.7.1 and 5.7.2 on Page 21
