6. Maintenance
6.1 General
• Make sure the maintenance instructions
under “After Use” are followed.
• If the device is not in frequent use (i.e. less
than once a month), the Device Test (see
section 7) should be performed both on a
monthly basis and after each use.
6.2 Clean the Cabinet and parts
Warning: Disconnect the LSU from external
power prior to cleaning.
Use a minimum of liquid to prevent any electrical
shock hazard. Do not immerse the LSU or allow
it to stand in water or other liquids. This can
damage the device, and cause electrical shock
resulting in injury to persons.
• Use a cloth or sponge that is dampened with
a mild detergent (hand dishwashing liquid or
similar) to clean the external surfaces of the
LSU. Use a detergent that is compatible with
the materials listed under section 11.7, and
follow the detergent manufacturer´s
instructions.
• Use a cloth or sponge dampened with water
and wipe the surfaces again.
• Dry the surfaces using a clean cloth or a
paper towel.
6.4 Charge the Battery
The internal rechargeable battery can be charged
directly from external AC or DC power as
described in section 3.4. No external charger is
needed. To charge the battery, proceed as follows:
1 Make sure the Operating Knob is set to “0”.
Connect either external AC or DC power to
the LSU and charging will start automatically.
2 During charging the Battery Status Indicator
will indicate approx. achieved battery capacity
(see section 3.2.5 for details).
3 The LSU should be placed on charge for a
minimum of 24 hours to reach full battery
capacity. The fast charging gives approx. 80%
capacity after 3 hours (for a new battery).
Repetitive charging for only 3 hours is not
recommended.
