How do I attach a switch to Mercury?

To use a single switch (for automatic scanning):

Insert the plug from the switch into the Switch 1-2 jack on the side of the Mercury. Click the

Setup

button in the Mercury Control Panel, then click the

Switches

tab and set Switch 1 to the function

required by the program you are using. Make sure that Switch 2 is set to Ignore.

To use two switches simultaneously (for dual-switch scanning):

Use a dual switch (such as the Rocker switch from Tash,

Inc.) and insert the plug into the Switch 1-2 jack on the

side of Mercury. Or, using 2 single switches, insert the

plug from each switch into a “splitter,” then plug the

splitter into the Switch 1-2 jack. The splitter (or “Y

Adapter”) is available from RadioShack

, and the

catalog number is 274-375B. The jacks are color-coded:

Nickel for left (Switch 1), and Gold for right (Switch 2).

To use the Wheelchair Joystick input:

See page 34 for information on using a Wheelchair

Joystick.

To turn Mercury on using a switch:

If you have a single switch attached, you can turn Mercury

on or wake it from Stand By mode by pressing the switch. If you

have two switches attached, switch 1 will turn the Mercury on or wake it

from Stand By mode.
