Set Call Waiting Prefix. If you have call waiting, you may choose to disable it while the
HD DVR is making a call, so that the HD DVR's phone call is not interrupted. If you do
not disable it, the HD DVR may drop the call and allow the second call to ring through,
depending on your phone system. The HD DVR will then try its call again later. The most
common code that phone companies use to disable call waiting is *70 (check with your
phone company to find out how to disable call waiting in your area). Press CLEAR to
enter a star (*). Press the PAUSE button after you have entered the prefix to insert a
comma, which creates a two second pause after the prefix is dialed.
Set Tone/Pulse. If your phone system uses pulse dialing, change the setting here.
Set 'Phone Avail.' Detection. When 'Phone Avail.' Detection is on, the HD DVR can
determine whether the phone line is in use by detecting voltage on the line. This allows it
to avoid disrupting a call in progress (such as another modem call).
This setting is off by default. With 'Phone Avail.' Detection turned off, if you are on the
phone when the HD DVR tries to call, you may hear a click on the line. If you have
another modem call in progress (on your computer or other device), that call may be
disrupted if the HD DVR attempts to call the DVR service. If you have a standard dial
tone, and 'Phone Avail.' Detection is off, turn on Dial Tone Detection (below).
If you are experiencing "Failed, Line unavailable" errors, or if the HD DVR is not making
successful connections, you may have a low-voltage phone system that the HD DVR
cannot detect. In this case, it's best to have 'Phone Avail.' Detection off.
Set Dial Tone Detection. This setting is on by default. If you leave it on, the HD DVR
checks for a dial tone before dialing. However, if you have a non-standard dial tone (as
some voice messaging systems have), the HD DVR will be unable to detect the dial tone
and will not connect to the DVR service.
