Switching the Noise Gate On/Off
An output noise gate operates when the telephone signal is below the noise
gate threshold control. This noise gate reduces the output gain by 34dB
under no signal conditions eliminating the affects of telephone line cross
talk. The noise gate can be switched off if you don’t wish to use it by adding
JP1 on the main circuit board.
JP1 ON – Noise Gate Off
JP1 OFF – Noise Gate On
Adjusting the Noise Gate Threshold
The noise gate is factory set to –26dBu to avoid interaction with the
equipment null. To adjust the noise gate threshold, use a jeweller’s
screwdriver to adjust RV4 on the main HY-03 circuit board.
Note: The noise gate threshold is factory set for optimum performance, so
will not normally need adjustment.
Important Note: There are a number of other controls which are factory
set, or should only be used when testing/aligning the product. These
are RV2, RV5, RV6, RV7 and jumpers JP2 and JP3. Please note that these
controls should not be adjusted in normal operation and could damage
the performance of your product if altered. Adjusting these settings will
invalidate the warranty on your product.
Using the Dial Tone Disconnect Option
The optional HY-03DTD Dial Tone Disconnect PCB allows the HY-03 to drop a
call automatically when the pre-configured tones are detected.
To use Dial Tone Disconnect, SW1 on the rear panel must be set to on, and
the appropriate jumper(s) JP1-JP16 on the Dial Tone Disconnect PCB must
be fitted to enable detection of the required tone(s). For example, to enable
the HY-03 to detect the dial tone in Finland, set the rear panel SW1 to ON
and set the jumpers on the HY-03DTD board over JP1, JP2 and JP3.

Figure 2-5 : Jumper settings on the
HY-03DTD board
If the HY-03DTD board has been
supplied for you to upgrade your
HY-03, fit the correct jumpers on
the board as below, follow the
instructions on page 7 for opening
the unit and plug it in, as per Figure
2-4. Make sure that there is a secure
and firm connection between the
plug-in headers, and fit the supplied
threaded M3 x 12mm pillar between
the two boards using the supplied
M3 x 6mm pan head posidrive screws
(one bottom and one top). Replace
the HY-03 main board into the HY-03
chassis.
See Table D on the following page
for a list of the tones currently
implemented.
