After entering the command described below, turn on the power again.  If the same contents as shown on the
next page appear on the screen, you can confirm that "SS unit" has been started up normally.

1. Preparations:

1

 PC (with Teraterm communication software installed)

2

 Dedicated connector cable

(Checkup procedure)

1

 When you are done with the connection as shown above, turn on the power.

2

 Several seconds after powering up, the screen will stabilize.  Then, hold down Shift key and ~ key simultaneously

for a few seconds to call the prompt.

~

Wireless Center prompt = "$"
TV receiver prompt = "%"
When the sequence ~~~.. appears, press Enter key once to show a single prompt.

3

 Enter the following command, and press Enter.  "eepw_0x80_0x03" (_ indicates a space.)

4

 Turn the power off and then on again.

5

 When you have finished checking all display items on the next page, repeat the steps starting from 

1

.  In the

step 

3

, enter "0xFF" instead of "0x03" to put the setting back to a default.

2. Writing and reading the ID code

When either the transmitter or receiver of the SS unit has been replaced, it is necessary to match the ID code
of the transmitter and receiver.

1

Writing the ID code

•

Using the terminal software, call the above screen and key in the following command. Then press the Enter
key.
"idw_

~~~~~~~~

" (

~

 represents a new ID code.) (_ means a space.)

2

Reading the ID code

•

Using the terminal software, call the above screen and key in the following command. Then press the Enter
key.
"idr"

•

Press the Enter key again, and the ID code will appear.
Note: Be sure to enter the ID code assigned to the set in order to avoid confusion with other sets.
