DIP switches (1 & 2)

The two DIP switches are both on when in the
down position. As shipped from the factory,
switch 1 is off (up) and switch 2 is on (dow), and
you probably will not need to change them.

However, when a passive device is connected to
the

EXT 1

connector and power is not provided

from the device to the tally supply pin, this switch
1 (

TALLY POWER

) should be set to the on

(down) position, allowing the RC-898 to use its
own power for this purpose.

Switch 2,

GND LIFT

(ground lift) controls the

isolation of the ground of the RC-848/DTRS sys-
tem from the ground of devices attached to the

EXT 1

and

EXT 2

ports. Usually this switch is in

the on (down) position, but you may need to turn it
off (up) if your system suffers from hum prob-
lems. However, a full discussion of ground loops
and their associated problems is outside the scope
of this manual, and we recommend that you con-
sult one of the many reference works on this sub-
ject if necessary.

Contrast

This control alters the contrast on the backlit LCD
display screen [11]. Use it to set the screen so that
it is easily visible from your preferred viewing
angle.
