Features
●
The JHS-32B VHF radiotelephone meets the
ITU Radio Regulations, IMO Performance
Standards, and ITU-R Recommendations.
●
The JHS-32B VHF radiotelephone covers all
channels specified in the ITU Radio Regula-
tions.
●
The JHS-32B VHF radiotelephone can be
easily installed in a narrower space because
all the necessary units, transmitter/receiver,
antenna duplexer unit, DSC unit, CH 70 DSC
Watchkeeping Receiver and power supply
are built-in in a compact body.
●
The JHS-32B VHF radiotelephone incorpo-
rates a large graphic LCD with wide angle of
visibility. The LCD does not limit the place for
installation.
●
The JHS-32B VHF radiotelephone LCD
display automatically instructs the operator
according to the operator’s needs, when an
item is selected from the menu. This makes
any operation easy, DSC in particular.
●
The JHS-32B VHF radiotelephone can be
used with the NKG-52 dedicated printer or a
general purpose printer with CENTRONICS
interface. The connected printer automati-
cally prints out the DSC messages transmit-
ted or received. A message stored in
memory can be manually printed out later on.
●
The brightness of LCD and keypad
backlighting is widely adjustable, and will not
disturb a night watch.
●
In addition to the channels specified by
Radio Regulations, the JHS-32B VHF radio-
telephone covers USA channels, Weather
channels, and Canadian channels available
along the coast of North America. Up to 99
private channels can also be incorporated.
●
The JHS-32B VHF radiotelephone incorpo-
rates memory channels, memory scanning
function, scanning function of all channels or
desired channels, and dual watching func-
tions. These functions are convenient for
watching particular channels.
●
Besides the usual radiotelephone communi-
cations, distress, urgency, safety, and routine
calls are available. When the coast station
offers automatic connection service to public
telephone subscribers, the service can be
used by inserting the desired telephone
number in the DSC message.
●
The JHS-32B VHF radiotelephone has an
interface for receiving position and time data
from a navigation aid such as GPS. When a
distress call is transmitted, position and time
data are automatically inserted in the DSC
message. When receiving an area call, the
JHS-32B VHF radiotelephone automatically
checks whether the ship is in the sea area
concerned by referring to position data
received from the navigation aid. During
normal operation, position and time data from
the navigation aid is available on the LCD at
any time, convenient for checking and report-
ing the position of the ship.
●
The JHS-32B VHF radiotelephone can be
connected to up to three remote controllers,
with the same operations as the JHS-32B
VHF radiotelephone.
●
By installing the NRE-322 Guard Receiver,
the operator can keep a continuous watch on
any two legal channels independently from
the JHS-32B, as required by the Administra-
tion of specific countries.
●
The JHS-32B VHF radiotelephone can be set
so that it automatically terminates transmis-
sion with an alarm, according to the FCC
Regulations in the USA, when transmission
continues for five minutes.
●
The JHS-32B VHF radiotelephone is pro-
vided with the self-diagnostic and error
display functions to ensure ease of checking
and maintenance.
●
The JHS-32B VHF radiotelephone incorpo-
rates the automatic power reduction circuit.
The circuit protects the transmission circuitry
from damage in case of high SWR due to
antenna or antenna cable failure.
