TX EXT SYNC: If two or more echo sounders or sonars are
operated simultaneously, mutual interference may result due
to asynchronous keying pulse output. To synchronize keying
pulse turn TX EXT SYNC on.
IR: Rejects interference. Turn off when no interference exists,
otherwise weak echoes may be missed.
STABILIZER: Select “ON” when the Motion Sensor MS-100
(option) is connected.
COLOR: Selects 16- or 8-color presentation.
RES COLOR: Sets echo presentation characteristics. LOG
enhances weak echoes and is normally used. LINEAR
downplays the weak echoes comparing with LOG. It is effec-
tive for suppressing the plankton layer. SQUARE enhances the
strong echoes comparing with LINEAR, resulting in clear and
easy-reading picture.
