PRECAUTIONS
CAUTION:
Attach
the
speaker-microphone's
connector
securely
to
prevent accidental dropping the transceiver, or water intrusion in the
connector.
(Seethe
transceiver's
instruction
for
installation
details.)
BE
SURE to
turn
OFF the transceiver's
power
when
attaching
to
the transceiver or detaching from the transceiver. Otherwise a mal
function
may
occur,
or maydamage the transceiver or
microphone.
NEVER immerse the
connector
in water. If the
connector
becomes
wet, be sure to dry BEFORE attaching it to the transceiver.
DO
NOT
use or
place
the
microphoneinareas
with
temperatures
below
-30°C or above
+60°C
(-22T to
+14CTF).
DO NOT
use
harsh
solvents
suchasbenzine or alcohol to clean
the microphone, as they
will
damage the microphone's surfaces.
BE
CAREFUL!
The microphone employs waterproof construction
(except HM-171GP/189GPS), which corresponds to IPX7 of the
international standard IEC 60529 (2001). However, once the micro
phone has been dropped, waterproofing cannot be guaranteed due
to the
fact
that the
microphone
may be cracked, or the
waterproof
seal
damaged,
etc.
DO
NOT
modify
the microphone for any reason. Repair should be
done at
authorized
Icom
service center
only.
Waterproofing
cannot
be guaranteed if you
open
the microphone yourself, or have it done
atanon-authorised
dealer/service
center.
USE specified Icom transceivers only. Other manufacturer's trans
ceivers have
different
pin assignments and may damage the trans
ceiver or
microphoneifattached.
While
connecting
the
HM-170GP, HM-171GP,
HM-175GPS
or
HM-189GPStothe
transceiver
and
the
transceiverisset
the
GPS
automatic transmit function, the transceiver transmits automatically
at
every
setting
interval. This is
normal
and
does
not indicate
an
equipment
malfunction.

About
calculating
position
The
GPS
receiver receives signals from
GPS
satellites. It calculates its posi
tion by
the
orbit
informationofthe
GPS
satellites
and
needstomeasure
the
distance
between
itself
and
threeormore
GPS
satellitestoobtainareliable
position. A receiver acquires all available satellites when it is first powered up,
powered oft for a long time, or powered up again at a place a long way from
when it was last powered off. Normally, it
takes
approximately 1 minute for
determining a position.
In
places
where
the
GPS
signals
cannot
reach
the
GPS
receiver
suchasin
caves,
underground,
indoors,
under
overpasses,
beside
tall buildings, or
near
any
other
devices
that
cause
electronic
interference,
the
GPS
receiver may
show
position
errors
(misplacement)
or no position
readingatall.
As the satellites
are
continuously moving,
measurement
of the position or
time by the
GPS
receiver
may
take
a while,
and/or
no position
reading
can
be
madeinsome
instances.
Evenifthe
GPS
receiver
receives
signals
from
threecrmore
satellites, it
may
takealonger
time to
determine
a position
dependingonthe
satellite locations.
Radio wave reception from the satellites is not only blocked by buildings
and
trees,
but
alsobythe
human
bodyinsome
instances.
Therefore
the
GPS
antenna
should be keptasfar away from the bodyaspossible for
best
recep
tion.
About
Almanac
and
Ephemeris
Data
To reduce the time for calculating position, the
GPS
receiver
stores
the
Almanac
Data
(the
orbit course-orbital
parametersofthe
satellites) in its inter
nal memory.When the
GPS
receiver is left with the power OFF for a long time,
the
GPS
receiver
needs
to acquire the Almanac Data again. In this
case,
the
receiver
startsasa
"cold"
start.
The
GPS
receiver
stores
Ephemeris
Dataofthe
satellite's
orbital
course,
and
referstothis
data
when
the
GPS
receiveristurned
OFF
forashort
time.
This
is called a "hot"
start,
and
uses
the
Ephemeris
Data
that
is valid to within
less
than4hours.

Location
precision
The GPS receiver automatically calculates its position when the GPS receiver
receives
GPS
signals from
three
or more
GPS
satellites.
The
GPS
satellite's
measurement
error
about
±10
meters,
however
this
can
vary up to several hundred meters depending on the surrounding environ
ment.
When the
GPS
receiver is powered up again at a place a long way from when
it was last powered off, the first calculation of its position may be incorrect in
some
cases.
The
GPS
information
and
its accuracy varies
depends
on the
GPS
system
being
acquired,
place
and
time.
Generally a GPS receiver cannot obtain a clear signal from the satellite when
indoors. As a result, the
GPS
receiver may
show
position
data
several hun
dred meters from actual place, or may show no position reading at all.
About
NMEA
sentence
The
GPS
receiver
outputs
the
last
memorized
NMEA
sentence
if the current
position
data
cannot be received
due
to the
GPS
signal being blocked by a
building,
car
roof, etc., or it
takes
a long time to acquire the position data from
a cold
start.
In this
case,
the
NMEA
sentence
information may
also
include
an
"invalid"
Indication.
About
Condensation
Ifcondensation
appears
on the
outer
casing
of the
GPS
speaker
microphone
due to a sudden change in temperature (E.g. brought to a warm room from
a cold place), it is likely
condensation
has
also built-up on the inside of the
microphone. In this
case,
keep
the
microphone with power OFF at room tem
perature for
about
1 hour. Do not turn ON the microphone until the conden
sation
disappears,asthis will
damage
the
microphone.
