SEA 222 Operator's Manual
SEA
222
OPERATOR'S
MANUAL
Featuring a unique "softouch" keypad, the SEA 222 is as easy to operate as a
microwave oven. Just follow the directions in this booklet.
The "brain" of the SEA 222 is divided into two parts:
1.
290 factory programmed frequency pairs selectable by channel number
from EPROM memory.
2.
100 channels of "scratch pad" memory for front panel programming and
recall (Note:
10
of
these channels are "EMERGENCY" channels).
When operating your
SEA 222 please note:
1.
Any two-digit key stroke followed by "enter" will recall user-programmed
channels 10-99;
2.
Any 3 and 4-digit key stroke followed by "enter" recalls factory -programmed
channels.

FRONT PANEL CONTROLS:
DISPLAY:
The
eight-digit alphanumeric display provides the operator
with frequency and
channel data.
4 x 4
KEYPAD 16 keys allow the operator to communicate with the computer
which
controls radio functions. For simple operation, an
"operator
friendly" software package is used in conjunction
with the
display. All of the keys are listed below.
ENT
Enters
previously keyed data into the computer.
Number Keys
Keys numbered
0 through 9 enter required numerical data
into the computer.
(Arrows)
.....
These keypads permit receiver tuning up
or
down
in
100 Hz
steps.
CH/FR
Allows the operator to display either channel number
or
the
frequency
of
operation. Example: pressing this key when the
display reads "CHAN 801" causes the display to indicate the
receiver operating frequency 'assigned to
channel number
801
(8718.9
KHz).
SQL
Activates
or
deactivates the voice operated squelch system.
When the
squelch is activated, the most significant digit in the
display will contain the letter
"Q."
EMER
Allows
..
operator instant recall of programmed emergency
channels.
TO PUT YOUR SEA 222 IN THE
OPERATING
MODE:
Turn the volume
ON/OFF
knob on. The display will read "SEA 222", then
"2182.0."
After three minutes the radio is ready to operate on 2182.0 kHz (to comply
with FCC standards).
TO DIM THE DISPLAY:
Press: any single digit followed by "ENT''
("O''
being off and "9" being
bright).
Example:
"9", "ENT" (brightest display)
"O",
"ENT" (extinguishes display)
Restore display to maximum brilliance by touching any keypad when
display is extinguished.
TO TURN THE AUDIO FEEDBACK
OFF/ON:
To
turn off the beep, enter any even digit and the "ENT" key.
Example: Press "6", "ENT''.
To
turn the beep back on, enter any odd digit and the "ENT" key.
Example: Press "7", "ENT". Note: this modification only affects SEA
222's with serial number higher than X2724.

TO SELECT CHANNELS OR FREQUENCIES STORED IN THE
FACTORY PROGRAMMED MEMORY
OF
THE SEA 222,
FOLLOW THESE STEPS:
The factory programmed frequencies are listed on page 7 of this booklet.
Access to these frequencies is explained on pages

is
ready to
operate on
Channel 403.
TO DISPLAY THE FREQUENCY ASSIGNED
TO
A CHANNEL NUMBER:
Press:
"CH/FR"
keypad while your desired channel number
is
displayed.
Example:
Press
"CH/FR"
keypad when the display reads "CHAN 403".
Display will indicate the receiver frequency 4363.6
KHz.
Press:
"CH/FR"
keypad again, display will revert back to
"CHAN 403".
TO PROGRAM THE SEA 222 "SCRATCH
PAD"
MEMORY:
Press: 8888888 (seven
8's).
Display will read: "PROGRAM," then "BIN #?".
The SEA 222 is now
in
Program mode.
Press: Desired two digit bin number, then
"ENT'.
Example:
Press "10"{ "ENT'.
Display will
read "TX FREQ".
Press: desired transmitter frequency (if programming receive only frequency, press
"ENT').
Example:
Press 124292, "ENT".
Display will
read "A3A?".
Press: "1'', then
"ENT'
for channels requiring -16dB carrier
insertion (A3A
is
seldom required) or
"ENT'
for normal
A3J
(no
carrier operation).
Display
will read: "RX FREQ".
Press:
"ENT'
for simplex frequency, or your desired
RECEIVER
fre-
quency for
DUPLEX or receive only frequencies.
Example: For DUPLEX channel press:
1,
2,
3,
4,
5,
6,
"ENT'.
This will enter the frequency 12,345.6 KHz
in
the receiver
frequency memory.
Display
will read: "STORED".
4
(
The frequency
is
stored
in
BIN
10.
The radio is now ready to program the next location.
Display will
flash "BIN#?".
Note: To program emergency channels, follow the previous steps,
using a
single digit number (0-9) instead of a two digit number,
followed by "ENT'.
TO REPROGRAM A CHANNEL:
To
overwrite already programmed information:
Re-enter Program Mode (Press
"8888888").
Press desired two digit
BIN
#, then "ENT".
Example: "10", "ENT".
Display will
read "BIN FULL".
Press: any numeral
key.
Example: Press
"1

SEA
222
"SCRATCH
PAD"
MEMORY.
TO ERASE CHANNEL FREQUENCIES:
Enter the program mode and select the channel to be erased. The display
will
prompt "BIN FULL". Press any numeric key. The display will
prompt "TX FREQ?", press "ENT'. The display will prompt "RX FREQ?",
press "ENT". The frequency information for that channel has been
erased and the
display will prompt "BIN#?".
TO ENTER SCAN MODE:
Channels 10-19 are reserved for scanning and you can program up to
10
channels using the program mode.
To
activate, turn radio off, then on to
set coupler
in
neutral tuning mode (it may be necessary to reprogram
squelch
threshold for satisfactory operation).
To
start scanning, press
"CH/FR",
then"•".
Scanning stops on active channels and resumes
when channel becomes inactive.
To
step over an unwanted active chan-
nel, press
"4.
".
To
stop scanning, press "EMER" (stops on present
channel).
TO RECALL A FREQUENCY OR CHANNEL FROM
SCRATCH
PAD MEMORY:
Press desired two digit
BIN
#,
"ENT".
Example: Press: "10", "ENT".
Display will read: the receive frequency stored
in
that bin, or
"empty".

6
(
POINTS
TO
REMEMBER:
•
It
may help to read the comprehensive instructions in your SEA 222
Instruction and Maintenance
Manual before attempting to operate your radio.
The information
in
this booklet is a shortened version of those instructions, and
assumes a certain
.level of familiarity with the equipment. For your conven-
ience, keep this
"how to" information and frequency listing in a handy place for
quick reference on board your vessel.
0
Let your SEA 222 warm up for at least three minutes. Transmitting
before 3 minutes may
result
in
a violation of
FCC
regulations.
•
Confused? If at any time during the programming process, you are
uncertain as to how to proceed, press
"EMER" or just wait 10 seconds. At this
point you may re-enter the
Program Mode and try again.
• Any frequency between 2000.0 kHz and 24000.0 kHz may be
selected for entry into the "scratch pad" memory. Before using them,
remember they must be
legally authorized for the desired operating service.
Unauthorized use of frequencies could result
in
a citation by the
FCC.
When
the
SEA 222 is to be used
in
services other than the marine service, it is
possible to provide a special program for the permanent memory. Contact the
factory for information regarding special programming.
