Ferrite Core Installation
To suppress RF interference that can cause abnormal operation of the
transceiver, attach the supplied ferrite core to the DC Input Cable, Accessory
Connection Cable, and External Speaker Cable together, then snap its two
halves together, per the illustration below.
Attach the ferrite core as close as possible to the transceiver body, as shown.
Finally, wind some plastic tape around the ferrite core, to prevent vibration
from causing the two halves to split apart.

Fuse Replacement ( 125V 6A )
To take out the Fuse from the Fuse Holder, hold
both ends of the Fuse Holder and pull the Fuse
Holder apart without bending the Fuse Holder.
When you replace the Fuse, please confirm that
the Fuse is tightly fixed on the metal contact
located inside the Fuse Holder. If the metal con-
tact holding the fuse is loose, the Fuse holder
may heat up.
