TEL Telephone Directory - stores telephone numbers, names, and
addresses, plus six other types of
information.
MEMO Memo - stores any type of important record.

The telephone directory, memo, scheduler, and reminder modes are the
databank modes that let you store, recall, edit, remove, and transfer
records. For complete instructions on using the databank modes, see
"Databank Operation".
RESETTING THE EC-442
Before you operate the EC-442 for the first time, reset it to clear any
records that might already be in its memory.
WARNING: The following procedure erases all data stored in the memory,
including mark-protected data (see "Marking a Record"). Perform
this operation only when you want to delete all data and re-
initialize the EC-442.
1. Press RESET on the back of the unit with a thin, pointed object, such
as a straightened paper clip.
2. Turn over the unit. The display shows the following:
ALL DATA CLEAR! OK? Y/N
Press Y to reset the memory and delete all data or N to cancel the reset
operation without deleting anything.
These are the initial settings produced by the reset operation.
Home Time Zone: London (LON) Schedule Alarm: ON
Home Time Setting: 12:00 AM, Reminder Alarm: ON
January 1, 1992 Daily Alarm: Off
12/24-Hour Clock: 12-Hour Clock Key Tone: On
World Time: New York (NYC) Character Input Mode:CAPS
Daily Alarm Time: 12:00 PM
NOTE: If the EC-442 is exposed to a strong electrostatic charge, the
display might dim or the EC-442 may lock up. First try resetting
the EC-442 by the above procedure. If this still does not correct
the problem, remove the battery compartment cover screw and press
the button inside. Then perform the reset operation to initialize
the databank.
TURNING THE EC-442 ON AND OFF
Press ON to turn on the EC-442. Press OFF to turn it off. If you do not
press a key within about 6 minutes, the EC-442 automatically turns off.
To restore power, press ON.
NOTE: If the EC-442 turns itself off while in the data entry mode, the
data is not stored.
Data Error
When you turn on the EC-442, it performs a self check before beginning
operation. If the EC-442 detects a problem with the data in memory, it
displays this message:
DATA ERROR! CONSULT THE OWNER'S MANUAL
Once data is lost, it cannot be recovered. Such data errors are generally
caused by one of the following problems.
Interruption of battery power.
Severe electrostatic charge, impact, change in temperature, or change
in humidity.
Hardware problem.
When the Data Error display appears, you cannot enter or edit data,
although you can recall data after pressing CLEAR. To return memory to
normal so you can enter and edit data, perform the reset operation to clear
the memory (see "Resetting the EC-442"). Before doing so, make sure you
have a written record of any important data. You can then re-enter the
data after clearing the memory.
If you still have trouble after trying the reset operation, you might have
a hardware problem. If so, consult your local Radio Shack store for
assistance.
ADJUSTING THE DISPLAY CONTRAST
Rotate CONTRAST on the left side of the unit to make the display lighter
or darker.
CURSOR KEYS
The _ on the screen is called a "cursor." The cursor indicates the
position where you enter the next letter, number, or symbol.
The cursor keys move the cursor to the right or left along a data line,
and up or down to other data lines. Arrows are not marked on the cursor
keys, but for explanation, we use the arrow symbols in this manual.
