DO NOT USE CHAIR UNTIL YOU HAVE FULLY READ THE INSTRUCTIONS

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.
