IMPORTANT!
Any digital or electronic telephone button
can be activated from the remote terminal
at any time while in the Test Mode (even
while the end user is using the telephone).
Therefore, caution must be used to prevent
service interruption or interference. The
Test Mode provides status tests to check
whether or not a station or CO line is in use.
The status checks should always be made
before performing other tests.
