Radio Shack TAD 3809 - Manual (Page 10)

10 Preparation
Cautions:
You must use a Class 2 power source that sup-
plies 9V AC and delivers at least 440 mA. Its plug
must fit the TAD's
AC 9V 440 mA jack. The sup-
plied adapter meets these specifications. Using an adapter
that does not meet these specifications could damage the
TAD or the adapter.
• Always connect the AC adapter to the TAD before you con-
nect it to AC power. When you finish, disconnect the
adapter from AC power before you disconnect it from the
TAD.
Note: When you first connect power,
0#0 0#0 0#0 0#0
flashes on the display,
then the TAD runs a self-test. You cannot operate the TAD dur-
ing this test. When the test is complete, the TAD beeps once,
then displays
33 33 33 33

Preparation
SETTING THE DAY AND TIME
To avoid having to reset the time if AC power is lost, we recom-
mend you install a battery before you set the day and time (see
“Installing the Backup Battery” on Page 8).
Note: If you pause for more than 8 seconds during setup, the
TAD sounds a three-tone beep and stops setting the day and
time. If this happens, start over at Step 1.
