• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.

It is necessary to remove the soldering on the short circuit point after connecting the flexible cable.

The protection circuit is activated when a failure in power or voltage is generated in the D-AMP circuit. If the protection circuit is activated, the unit will shut itself off and the TIMER indicator on the front panel will start flashing. The indicator will continue to flash until the problem is resolved. After a shutdown, to turn the unit back on, unplug the AC power cord then plug it back into the AC outlet.
