Note

When using the RS-481 Option handset, cut the jumper

wire next to the handset joint connector on the circuit board

as illustrated above.

If not cut, sound comes out from the RS-480's front

speaker and returns back to the handset’s microphone,

resulting in acoustic feedback.

Notes

• When using the PA paging function,

keep the switch panel as far away

from the PA paging speaker as

possible to avoid acoustic feedback.

• When installing the RS-480 at

outdoor or locations where it gets wet

with water, tightly seal the panel

edges. Besides, provide a weep hole

at the underside of the mounting box

to permit water to drain off.
