OPERATING INSTRUCTIONS
4.1.0 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.
4.2.0 POWER UP
4.2.1 PARAMETER MEMORY
The unit contains nonvolatile memory that stores the
most recently programmed values for the following pa-
rameters;
1. Operating Frequency
2. DPL Code
3. PL Frequency
4. Tone A and B
a) Frequency
b) Duration
c) Delay
5. Deviation Alarm Limit
Also included in memory are the most recent state of the
following membrane keys;
1. DEV
±
2. RF V/dBm
3. Display select arrows (left and right)
4. DVM AC/DC
5. Code Synthesizer Modulation select arrow
(vertical)
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, or
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, 1313 East Algonquin Road, Schaumburg,
Ill. 60196.
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;
Operating Frequency-100 MHz
D PL Code--000
PL Frequency-100 Hz
Tone A
a) Frequency-! kHz
b) Duration--0.5 Sec
c) Delay--0.0 Sec
Tone B
a) Frequency-1.5 kHz
b) Duration--0.5 Sec
c) Delay--0.0 Sec
Deviation Alarm Limit--0.0 kHz (alarm off)
DEV
±
initial state is
+
RF V/dBm initial state is Volts
Display Select (left) initial state is SINAD
Display Select (right) initial state is RF LVL or RF
PWR
DVM AC/DC initial state is AC
Code Synthesizer Moduhtion select initial state is TN
REM
NOTE: The Lithium Battery used for non-volatile
memory is included in every unit and is independent
of the optional RTP-4021A Battery Pack Option.
All functions that are controlled by toggle switches, ro-
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 200kHz
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.
4.3.1 OUTPUT LEVEL
Output in the "GEN" function is available at the "RF
IN/OUT" connector. Voltage output range is .1 uV to
200 u V 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 u V to 1
VRMS. This is sufficient for transmission through an
antenna connected to the antenna connector.
