PREPARATION
SETTING THE MW (AM)
TUNING INCREMENT
In the United States, the Federal Com-
munications Commission (FCC) as-
signs frequencies for stations in the
MW band in 10-kilohertz increments.
(In the United States, we commonly
call the MW band the AM band.) In Eu-
rope and some other parts of the
world, MW frequencies are assigned in
9-kilohertz increments.
The MW STEP switch is located in-
side the battery compartment. Before
you install the back-up batteries, set
the switch to
9k or 10k using the fol-
lowing guidelines:
• If you are in the United States,
Canada, or another North or
South American country, be sure
the switch is set to
10k .
• If you are in a country where
the AM frequency increments
are 9 kHz, set the switch to
9k .
INSTALLING BACK-UP
BATTERIES
Back-up batteries power the receiver’s
clock and the display and save the sta-
tions stored in memory if the receiver’s
primary power source is interrupted.
The receiver uses three AA batteries
for back-up power. For the best perfor-
mance, we recommend alkaline bat-
teries, such as Radio Shack Cat. No.
23-552.
Note: You cannot operate the receiver
using only the back-up batteries. If you
press
POWER when the back-up bat-
teries are the only available power
source,
E flashes on the display.
Follow these steps to install the back-
up batteries.
1. Remove the battery compart-
ment’s cover by pushing the cover
in the direction of the arrow.
2. Install three AA batteries, according
to the polarity symbols (+ and –)
marked next to the compartment.
For easy removal, place the bat-
teries on top of the lift-out ribbon.
