[45]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.

[46]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.
