SAVE
THIS INSTRUCTION MANUAL-This
in-
struction manual contains important operating instructions for
the IC-T2H
.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual .
CAUTIONS
,&WARNING! NEVER hold the transceiver so that the
antenna
is
very
close
to,
or touching exposed parts of the
body, especially
the face or eyes, while transmitting . The
transceiver will perform
best if the microphone is 5 to 10 cm
(2 to 4 in)
away
from the lips and the
transceiver is
vertical .
,&WARNING! NEVER operate the transceiver with
a
headset or other audio accessories at high volume
levels .
Hearing experts advise against continuous high volume
op-
eration . If you experience a ringing in your ears, reduce
the
volume or discontinue use .
NEVER connect the
transceiver to an AC
outlet or to
a
power
source of more than
16
V DC . Such
a
connection
will
damage
the transceiver .
NEVER connect the transceiver to a power
source that
is
DC fused at more than 5 A . Accidental reverse
connection
will
be protected by this fuse, higher fuse
values will
not give any
protection against such accidents
and the
transceiver will
be
ruined .
NEVER attempt to charge alkaline
or dry
cell batteries
. Be-
ware that external DC power
connections
will charge
batteries
inside
the
battery case . This will damage
not
only the battery
case but also the transceiver .
DO NOT

DO NOT operate the
transceiver near unshielded electri-
cal blasting caps or in an
explosive atmosphere .
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below -10°C (+14°F) or above
+60°C (+140°F) .
The use of non-Icom battery packs/chargers may impair
transceiver performance and invalidate the warranty .
Even when the transceiver power is OFF, a slight current still
flows in the circuits . Remove the
battery pack or case
from
the transceiver when not using it for a long time . Otherwise,
the battery pack or installed Ni-Cd batteries will become ex-
hausted .
For USA only .
Caution
:
Changes or modifications to this transceiver, not ex-
pressly approved
by Icom Inc ., could void your authority to
operate this transceiver
under FCC regulations .
