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.

SEA 222 OPERATORS MANUAL
The eight-digit alphanumeric display provides the operator with
frequency and channel data.
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.
These keypads permit receiver tuning up or down in 100 Hz steps.
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.
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".
Allows operator instant recall of programmed emergency channels.
