OPERATION
The operator may use the LCD's and CRT display to
become
familiar with the functions the Communication
Service
Monitor
is capable
of performing. As
a
function
is
selected,
its parameters are displayed on the LCD's.

WARNING Lithium Battery
The processor module
within this
system utilizes
a
lithium battery
as a
memory keep-alive voltage source.
Do not mutilate or
disassemble
the battery cell.
The
lithium metal
is
a
very active material that burns in
the
presence
of
water
or
high humidity.
Do not put
the
battery in fire, attempt to charge, heat above 100'C, of
solder
directly to the cell. Do not overdischarge the cell
to a
reverse
voltage greater
than 3
volts. The battery
may
burst and
burn or
release hazardous
materials.
CAUTION Lithium Battery
Lithium batteries are
classified
as
hazardous materials
and
must be
disposed
of
accordingly.
Do not
dispose
of
the battery by placing
it
in with
the
everyday
trash.
Consult state and local
codes
for the appropriate disposal
procedure. Motorola
will
dispose
of the
battery
if
the
expended
battery
is
returned in the replacement battery
container and by the
same
method that the new battery
came
to you,
send
to: Motorola Inc., Return
Goods
Department,
13L3
East Algonquin Road,
Schaumburg,
Ill.

4.2.2 DEFAULT
PARAMETERS
The unit
will initialize to the last active state
unless the
battery (P/N
60-83294N03)
which powers the
non-
volatile memory
is
faulty or
has
low output level due to
age
or defect.
(See
the maintenance manual for battery
replacement.) Should this occur the initialized param-
eter values
will
be;

REM
NOTE: The Lithium Battery used
for
non-volatile
memory
is
included in every
unit
and
is
independent
of the optional RTP-402IA Battery Pack
Option.
All
functions
that are controlled by toggle switches, fo-
tary switches
or potentiometers
are
initialized according
to the current positions
of the
switches.
4.3.0 GENERATE OPERATION
The
Service
Monitor
generates
RF frequencies for FM,
AM,
and
CW transmissions covering
a
range
of
200
kHz
to
1.
GHz. To generate
a
signal the
"FUNCTION"
switch
is placed
in the "GEN" or
"HI
GEN"
position.
NOTE: An RF protection circuit to protect
against damage
due
to inadvertent application of RF power to
the
unit
is
provided.
4.3.I
OUTPUT LEVEL
Output in the
"GEN"
function is available at the "RF
IN/OUT"
connector.
Voltage output range is .1
uV
to
200
uV into
50
ohms
for direct connection to the antenna
input of the equipment under service. Output in the
"HI
GEN" function
is
available at the antenna
BNC
connec-
tor of the unit. Voltage output range is
200
uV to
1
VRMS. This is sufficient
for
transmission
through
an
antenna connected
to the antenna connector.
