PRECAUTIONS
R
WARNING! NEVER immerse the connector in water. If
the connector becomes wet, be sure to dry before attaching
it to the transceiver.
CAUTION:
connector securely to prevent an accidental radio
dropping or water intrusion in the connector. (Refer to the
transceiver’s instruction manual or operating guide for
installation details.)
CAUTION: DO NOT use or place the microphone in areas
with temperatures below –30°C or above +60°C (–22˚F to
+140˚F).
CAUTION: DO NOT use harsh solvents such as benzine
or alcohol to clean the microphone, as they will damage the
microphone’s surfaces.
CAUTION: 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 at a non-authorised
dealer/service center.
BE CAREFUL! The microphone meets IPX7 requirements
(except HM-171GP), for waterproof protection. However,
once the microphone has been dropped, waterproof
protection cannot be guaranteed because of possible
damage to the microphone or the waterproof seal.
Use with specified Icom transceivers only. Other
manufacturer’s transceivers have different pin assignments
and may damage the transceiver or microphone.
While connecting the GPS speaker microphones to the
transceiver and using the GPS automatic transmit function,
the transceiver automatically transmits at every setting
interval. This is normal and does not indicate an equipment
malfunction.
Be sure to turn OFF the transceiver when attaching to the
transceiver or detaching from the transceiver. Otherwise a
malfunction may occur, or may damage the transceiver or
microphone.

About calculating position
The GPS receiver receives signals from GPS satellites. It
calculates its position by the orbit information of the GPS
satellites and needs to measure the distance between
itself and three or more GPS satellites to obtain a reliable
position. A receiver acquires all available satellites when it
is first powered up, powered off 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 such as in 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 reading
at all.
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 made in some instances.
Even if the GPS receiver receives signals from three or
more satellites, it may take a longer time to determine a
position depending on the satellite locations.
Radio wave reception from the satellites is not only blocked
by buildings and trees, but also by the human body in some
instances. Therefore the GPS antenna should be kept as
far away from the body as possible for best reception.
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 m,
however this can vary up to several hundred meters
depending on the surrounding environment.
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 hundred meters from its
actual position, 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 Almanac and Ephemeris Data
To reduce the time to calculate position, the GPS
receiver stores the Almanac Data (the orbit course/orbital
parameters of the satellites) in its internal 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 starts as a “cold” start.
The GPS receiver stores Ephemeris Data of the satellite’s
orbital course, and refers to this data when the GPS
receiver is turned OFF for a short time. This is called a “hot”
start, and uses the Ephemeris Data that is valid to within
less than 4 hours.
About Condensation
If condensation 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 temperature for about 1 hour.
Do not turn ON the microphone until the condensation
disappears, as this will damage the microphone.
