6—Using the S-4000 System

Setting the REAC MODE Switches

The REAC MODE switch on the S-4000S/S-4000H is recessed
from the front panel so that its setting can't be changed
inadvertently. To change the switch setting, use a blunt-tipped
instrument such as a ball-point pen, mechanical pencil, etc.
With their power off, set the units as follows:
1. On the S-4000S, set the REAC MODE switch to M.
2. On the S-4000H, set the REAC MODE switch to S.
If the REAC MODE switch setting is changed when the unit is powered on, the new setting won't
take effect until the unit is powered off and then back on again.

Component Connections

AC Power Connections

On the S-4000S:
• Connect one end of the supplied AC power cord to a grounded AC outlet,
and the other end to the INT. POWER AC INPUT jack to provide power for the
S-4000S's internal power supply.
On the S-4000H:
• Connect one end of the supplied AC power cord to a grounded AC outlet,
and the other end to the INT. POWER AC INPUT jack to provide power for the
S-4000H's internal power supply.
Use only the supplied power cords to prevent damage to the units.
An optional S-240P External Power Supply Unit can be used to supply redundant backup power
to an S-4000S or S-4000H unit. Visit www.RSSAmerica.com or contact an RSS dealer for more
