WARNING! NEVER
connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
NEVER
connect the transceiver to a power source of more
than 16 V DC or use reverse polarity. This will ruin the trans-
ceiver.
NEVER
cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting,
the transceiver may be damaged.
NEVER
place the transceiver where normal operation of the
vessel may be hindered or where it could cause bodily injury.
KEEP
the transceiver at least 1 m away from the ship’s nav-
igation compass.
DO NOT
use or place the transceiver in areas with temper-
atures below –20°C or above +60°C or in areas subject to di-
rect sunlight, such as the dashboard.
AVOID
the use of chemical agents such as benzine or al-
cohol when cleaning, as they may damage the transceiver
surfaces.
BE CAREFUL!
The transceiver rear panel will become
hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent
use by children.
BE CAREFUL!
The transceiver, HM-137 and optional
HM-134 employ waterproof construction, which corresponds
to JIS waterproof specification, Grade 7 (1 m/30 min.). How-
ever, once the transceiver or microphone has been dropped,
waterproofing cannot be guaranteed due to the fact that the
case may be cracked, or the waterproof seal damaged, etc.
