Memory Preservation
This unit does not require memory preservation
batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is unplugged. The unit must be plugged in order to
charge the back-up system.
WARNING:
TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE.
CAUTION:
TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO
USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
• Acoustic Presence Circuit Naturally En-
hances the Extreme Low Range
• Source Direct Function
• System Control Remote Controller
The memory preservation period after the unit
has been unplugged varies depending on climate
and placement of the unit. On the average,
memory contents are protected over a period of
a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit
is exposed to a highly humid climate.
WARNING
RISK OF ELECTRIC SHOCK
DO NOT OPEN
The lightning flash with arrowhead symbol, within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and maintenance
(servicing) instructions in the literature
accompanying the appliance.
