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 3, 4, and 5.
To select a channel by number: Press the desired three or four digit
channel number, then "ENT'.
Example: Press "403", then press "ENT'.
Display will read "CHAN 403". The SEA 222 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 fre-
quency, 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".

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 ".
Display will read "TX FREQ?".
Continue programming as explained in the section TO PROGRAM THE
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".
Then press: "CH/FR" keypad.
Display will read "CHAN 10".
(Note: Scratch pad memory must be programmed in the field.)
