The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean
“Lead-Free” solder. Thealphabet following the LF mark shows the kind of lead-free solder.
If the soldering iron tip is discolored black during soldering work, cleanand file the tip with steel wool or a fine filer.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after com-pletion of soldering work.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
Since the melting point of lead-free solder is about 220˚C, which is about 40˚C higher than that of conventional lead solder, and its
soldering capacityis inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may
cause land separation or mayexceed the heat-resistive temperature of components. Use enough care to separate the soldering iron
from the PWB when completion of soldering isconfirmed.
(2) NOTE FOR SOLDERING WORK
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
Since the melting point of lead-free solder thread is about 40˚C higher than that of conventional lead solder thread, the use of the
exclusive-use solder-ing iron is recommendable.
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a
breakdown or anaccident.

at 1 second intervals.
(Temperature
abnomaly)
The message “TEMPERATURE” blinks at 5-second intervals in the corner of the screen (Lower left corner at the fac-
tory default), and it indicates an abnormality in the internal temperature.
*It operates only when “FUNCTION” - “TEMPERATURE ALERT” is set to “OSD&LED” or “LED”.
When it is “OFF”, it does not blink. (Factory default: “LED”)
*Even when “FUNCTION” - “LED” is set to “OFF”, the setting of “TEMPERATURE ALERT” takes effect.
At the same time, the brightness is forcefully reduced by the internal processing of the LCD monitor.
If it is left in the above state and the internal temperature increases further, the monitor shuts off automatically. (Goes
into the standby mode.)
By cycling the main power or turning off and on the power by the remote controller, the screen can be restored to its original
state temporarily. However, it goes back to the standby status soon unless the cause of the temperature increase is removed.

rectly.
3 ) Insert the battery case into the remote control.
Insert until you hear a click.
MEMO
nDo not use a battery other than a CR2025 battery.
nThe preinstalled batteries in the remote control were installed at
the factory, and therefore may become depleted before the spec-
ified usage time is reached.
nWhen the batteries become exhausted, replace them with new
(commercially available) batteries.
nIf you will not be using the remote control for a long time, remove
the batteries.
■REMOTE CONTROL OPERATION RANGE
The operation range of the remote control unit is approx. 16.4 feet (5 m)
at an angle of approx 10° from the center to the top/bottom/right/left of
the remote control sensor.
CAUTION
nDo not expose the remote control unit to shock by dropping or
stepping on it. This could lead to a malfunction.
nDo not sit with the remote control in your pants pocket. This may
break the remote control.
nDo not expose the remote control unit to liquids, and do not place
it in an area with high humidity.
nThe remote control unit may not work properly if the remote con-
trol sensor is under direct sunlight or strong lighting.
nObjects between the remote control unit and the remote control
sensor may prevent proper operation.
nReplace the batteries when they run low as this may shorten the
