with
silicone
lubricant
prior
to
assembly
(See

and
hand
tighten.
Make
sure
to
use
the
silicon
sparingly
so
when
assembled,
any
excess
does
not
get
on
center
conductor.
Care
should
be
taken
not
to
get
any
lubricant
on
the
center
conductor.
2.
Wrap
the

while
continuing
to
wrap
object
with
“half

attachment
to
a
good
earth
ground
for
optimum
efficiency.
Contact

reputable
local
communications
shop
for
procedures
for
your
area.
Lightning
Arrestors
Lightning
arrestors
should
be
used
on
all
external

for
personal
protection
and

minimize
damage
to
the
transceiver
during
lightning
storms.
The

Enabling
Transmitter
for
SWR
Testing
The
ESTeem
195C,
195M
and
195H
are
packet
burst
wireless
modems,
so
measurement
of
the
forward
and
reflected
power
during
operation
is
difficult.
To
enable
the
transmitter
for
measurement
with
a
directional
wattmeter,
enter
the
following
software
command:
