leicht zugänglicher Unterbrecher einzufügen, oder
das Netzkabel muß mit einer in der Nähe des Geräts
befi ndlichen, leicht zugänglichen Wandsteckdose
verbunden werden, damit sich bei einer Funktionsstörung
die Stromversorgung zum Gerät jederzeit unterbrechen
läßt.

安全のために，周辺機器を接続する際は，過大電圧を持
つ可能性があるコネクターを以下のポートに接続しない
でください。

: PARALLEL REMOTE コネクター
: SERIAL REMOTE コネクター

上記のポートについては本書の指示に従ってください。

For safety, do not connect the connector for periph­eral device wiring that might have excessive volt­age to the following ports.
: PARALLEL REMOTE connector
: SERIAL REMOTE connector
Follow the instructions for the above port.

1-5. Lead-free Solder

Boards requiring use of lead-free solder are printed with a lead free mark (LF) indicating the solder
contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)

: LEAD FREE MARK

m
. Be sure to use the lead-free solder for the printed circuit board printed with the lead free mark.
. The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is

recommended to use the soldering iron having a temperature regulator.

. The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly

longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so
be careful.
