REMOVING THE BATTERY'S PACKING SLIP

Remove the packing slip by pulling it away from the EC-336.  Then, press
(STORE).

If the display shows a number other than 20000, press and hold down
(ERASE).  Then, use a straightened paper clip to press (RESET) on the back
of the EC-336.  A test pattern appears, and the EC-336 turns off after 40
seconds.  Press (TIME), (TIMER), (ALARM), (STORE), or (RECALL) to turn on
the EC-336.

If the display still does not show 20000, take the EC-336 to your local
RadioShack store where our personnel will assist you.

Note:  This clears all information from storage.  To reset the EC-336
       after you have entered information, see "Resetting the EC-336",
       in Faxback Doc. # 48349.

AUTOMATIC POWER-OFF

To conserve battery power, the EC-336 automatically turns off after about
7 minutes of non-use.  To turn on the EC-336, press (TIME), (TIMER),
(ALARM), (STORE), or (RECALL).

Note:  The EC-336 does not automatically turn off when the timer is
       running.  See "Using the Timer/Stopwatch", in Faxback Doc. # 48887.

STORAGE CAPACITY

The EC-336 stores about 20,000 characters of information.

To view the remaining storage capacity, press (STORE).  The amount of
storage still available appears in brackets.

Note:  To maximize your use of the available storage, use abbreviations.

TURNING THE KEY TONE AND HOURLY CHIME ON OR OFF

You can set the EC-336 so that a tone sounds each time you press a key and
a chime sounds at the beginning of each hour.  An indicator appears on the
display above CHIME if the tone and chime are turned on.

Use the following steps to turn the key tone and hourly chime on or off:

1.  Press (TIME).

2.  Press and hold (music symbol) for about two seconds so that the CHIME
    indicator appears or disappears.

VIEWING AND SETTING THE DATE AND TIME

The date and time display shows the month, day of the month, day of the
week, and time.

You can display the time in AM/PM format or 24 hour format.  The time
format also determines the month/date format.  In the AM/PM format, the
month comes first.  In the 24-hour format, the day of the month comes
first.

Complete the following steps to set the date and time.  To simply view the
date and time, press (TIME).

1.  Press (TIME).  The current settings for date and time appear.

2.  Press and hold (12/24) for about two seconds to change the clock
    format to AM/PM or 24-hour format.  (In the AM/PM format, A or P
    appears in the lower left corner of the display.)

3.  Press (SET) to change the date or time.  The cursor appears below the
    date's first digit.

4.  Enter the date.  If you selected the AM/PM format, enter the month
    first.  If you selected the 24-hour format, enter the day of the month
    first.  For example, enter March 5 as:

    AM/PM format: 03/05.

    24-hour format: 05/03.

5.  Enter the hour and minutes.  For example, enter 1:00 p.m. as:

    AM/PM format: 01-00.

    24-hour format: 13-00.

    After you enter the time, the cursor returns to the date's first
    digit.

6.  In the AM/PM format, press (A) or (P) to set the clock to AM or PM.

7.  Repeatedly press (DAY) to set the day of the week.

8.  When the correct date and time are displayed, press (SET) to store the
    date and time.

Note:  If the information you enter is invalid (for example, you enter 15
       for the month), the display returns to the previous date and time
       setting, and the cursor returns to the date's first digit.
