WARNING: Do not stow the fold-away handles when driving, or whilst DRIVE
assist is active. Ensure the brakes are engaged before stowing the fold-away
handles.
WARNING: When leaving a patient unattended, always switch off the DRIVE
assist function and apply the brakes.
21. DRIVE Assist Handle Deactivation & Automatic System Switch Off
If the DRIVE handles are not used for 3 minutes, they will deactivate; this is a safety
feature and is indicated by 3 rapid pulses of the system status indicator. The DRIVE
handles are reactivated by a short press on the ON/OFF Button; the system status
indicator will return to solid green. After 30 minutes of inactivity, the system will switch
off; a system restart is required to continue driving.
22. Battery Charge Level Indication, Battery Charging & Maintenance
The battery charge level is shown by the BATTERY LEVEL indicator (item 4, Fig.10).
There are 10 indicators, each block represents 10% of the 100% total charge.
Battery charge level indication is only displayed when the system is on.
To charge the battery, plug the mains lead into the charging socket on the trolley (item
19, Fig.4) and a mains wall outlet. It takes approximately 5 seconds for the system to
recognise that the charger is active and commence charging. Charging is shown by the
indicators illuminating in sequence, one-by-one, from the current charge level to the
10
th
indicator. When the battery is full, the 10
th
indicator will blink at double speed.
A new battery will take approximately 5hrs to fully charge from flat; this equates to 30
minutes per 10% of the full charge. It is recommended that the trolley is placed on
charge when not in use. It is perfectly acceptable to partially charge the battery for
short term use.
Even when the system is not in use, the battery drains slowly; a fully depleted battery
can be permanently damaged. Such damage is excluded from product warranty.
Therefore, it is strongly advised to fully charge the battery at least every 3 months.
Damage to the battery due to the battery not being charged for long periods is
monitored by the system software and is excluded from product warranty.
The charging figures quoted are dependent upon the age and condition of
the battery, and are guidelines only.
DRIVE assist is deactivated when the trolley is charging.
CAUTION: Ensure the mains charging lead is disconnected before attempting
to raise the backrest, or move the trolley; failure to do so could result in
damage to the trolley or the fabric of the building.
CAUTION: Fully charge the battery at least every 3 months to avoid fully
depleting the battery, and causing permanent damage to the battery. Such
damage is excluded from product warranty.
23. Using DRIVE Assist with no Battery Power
The trolley can still be manoeuvred and steered when there is no battery power, as the
DRIVE wheel will free-wheel. However, there will be no DRIVE assistance or DRIVE wheel
braking.
24. DRIVE Assist Wheel Braking
The DRIVE wheel brake will engage under the following conditions;
When the trolley is brought to a stop, the DRIVE wheel brake will remain active for
2 seconds; this is a safety feature to prevent ‘unintended movement’. If the trolley is
pushed or pulled not using the DRIVE handles, i.e. using the side rails, or patient
deck grab handles, then the DRIVE wheel brake will activate. After 2 seconds of
