Using your finger, slide the battery to the left
(you will feel slight resistance by the the spring),
then slightly pry up the right side of the battery,
so that it is free to eject upward and outward
through the vertical slots at the top and bottom
of the plastic battery holder (Figure 10).

Carefully note the polarity (positive
+
side fac-
ing up) and battery type information. The re-
placement battery is installed in the reverse
manner.
Caution!
Do not dispose of the old lithium battery in
the fire, to prevent possible explosion. Also,
ensure safe disposal to prevent small children
from accidentily ingesting or choking on a
cell.
Backup Switch
Located on the rear panel of the receiver is the
memory BACKUP ON-OFF switch. It is normally
kept in the ON position to ensure that your memo-
rized information is maintained(by a small amount
of power from the Lithium Battery) when the radio
is off, or the
DC
power source is removed.
If you do not plan to operate your radio for
extended periods of time, turn this switch OFF to
conserve battery life. Move the selector using the
tip of a ball point pen or similar object. To prolong
lithium battery life, ensure the radio is l r n e d on
while switching the BACKUP switch from OFF to
ON. This reduces the current demand placed on
the battery by the radio's circuits from an un-pow-
ered state.
Note!
Memurized settings will be lost and the radio
will return to the factmy default settings,
when turning off the backup batte y. This has
the same efect as perfmming the power-on
sequence as described on page 22.
Cover Screws

bottom cover attachment. Refer to figure 12 if there
