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-congured 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
tted 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.
If the HY-03DTD board has been supplied for you to
upgrade your HY-03, t 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
rm connection between the plug-in headers, and t 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.
