Blood Pressure Monitor  (630-0639)   Power Source      Faxback Doc. # 3431

INSTALLING THE BATTERIES

You need four AA batteries (not supplied) to power the monitor.  For the
best performance, we recommend Radio Shack Cat. No. 23-552.

Follow these steps to install the batteries.

1.  Press down on the battery compartment cover and slide it off in the
    direction of the arrow.

2.  Install the four AA batteries as indicated by the polarity symbols
    (+ and -) marked inside the compartment.

3.  Replace the cover.

Notes:  Never leave weak or dead batteries inside the monitor.  If you are
        not going to use the monitor for an extended period of time,
        remove the batteries.

        When batteries become weak, SYMBOL appears on the display.
        Replace the batteries.

USING AC POWER

You can power your monitor from AC power, using an AC adapter such as
Radio Shack Cat. No. 273-1655 (not supplied).

Caution:  You must use an AC adapter that supplies regulated 6 volts and
          delivers at least 700 milliamps.  Its center tip must be set to
          positive, and its plug must correctly fit the monitor's
          DC 6V jack.  The recommended adapter meets these specifications.
          Using an adapter that does not meet these specifications could
          seriously damage the monitor or the adapter.

Follow these steps to use an AC adapter:

1.  Set tip polarity on the AC adapter to positive (+), following the
    instructions supplied with the adapter.

2.  Insert the adapter's plug into the monitor's DC 6V jack.

3.  Plug the other end to the adapter into a standard AC outlet.

Caution:  When you finish using the AC adapter, disconnect it from the
          AC outlet first, then unplug it from the monitor.
