Selecting the "1:OPTICAL" on the TEST COMMU-

and at the master BHT, select the "2:MASTER."
Then press the  ENT  key on each BHT.

During the test, the screen shown at left is dis-
played.

If any error occurs, the tested slave BHT beeps
three times and shows the screen at left.

In parentheses are error codes which have the
following meanings:

(X X)

1: The received data is different from

the sent data.

from the occurrence of an error.
