Radio Shack DX-392 owner manual Preparation, Installing BACK-UP Batteries

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.
