PRECAUTIONS
WARNING! NEVER immerse the connector in water. If the connector becomes
wet, be sure to dry before attaching it to the transceiver.
CAUTION: DO NOT attach the speaker-microphone’s 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 NO T 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.

ATTENTION ABOUT THE GPS RECEIVER
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.
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.
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 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.
