mode or vacuum level, or returning power unit to stand-by mode). The power unit will lock again 1 minute after last
button operation. Pressing this button will also illuminate the display screen for 10 seconds if power unit is in battery
operation (screen will always be illuminated in mains operation).
5.3 User Selectable Functions
The following functions are selectable in a user menu:-

5.5 Battery Information
• A fully charged battery should operate the power unit continuously for at least 24 hours.
• Charge status is shown on the display of the power unit when it is in stand-by and run mode.
• As the batteries are automatically charged as required when the system is operating on mains power, the battery module
should not require removing or changing in normal use.
• Use only the mains adapter supplied with the system.
• When power unit operation times when running from the internal battery are noticeably shorter than normal, it is time to
replace the battery pack. Contact Direct Healthcare Group or authorised dealer for battery replacement service.
• Never use any battery pack that is damaged or worn out. Use the battery pack only for its intended purpose.
• The battery pack is not serviceable and should be replaced if faulty (indicated by applicable battery faults displayed in
place of battery charge status icon). Contact Direct Healthcare Group or authorised dealer for battery replacement service.
• The internal Lithium Ion Battery may be received or become inert if left for extended periods in storage or a fully discharged
condition. Connection of a power adapter will wake / charge the battery and immediately allow the full use of the vacuum
power unit. It is possible to force the vacuum power unit into making the battery inert should this be required by some airline
and other carriers. See ‘User Selectable Functions’ Menu for details (Page 8).
