Using the Motorola MWR839 Weather Alert Radio
Your radio can operate with batteries (not included) or electricity.
Connecting the Power

unit.
2. Plug the adapter into the wall outlet. The Vdc and plug indicator
will appear on the upper left corner of the LCD display.
Battery Installation
Your Motorola MWR839 Weather Alert Radio uses 4 AA batteries
for back-up power. It can run on non-rechargeable alkaline, or
rechargeable Nickel Cadmium (Ni-Cad) or Nickel Metal Hybrid (NiMH)
batteries. When the radio is operating on battery power, the battery
indicator will appear on the upper left corner of the LCD display.
To Install or Replace the Batteries:
1. Turn the unit upside down. Locate the battery compartment door tab,
press down on the door tab and lift the cover up to open.
2. Insert 4 x "AA" size/UM-3/LR14 batteries. Be sure to follow the polarity
markings. Replace the battery compartment cover.
3. Reduced power, distortion, a "stuttering" sound are all signs that the
batteries may need replacing. The batteries should be replaced when
the battery indicator flashes in the display.
4. If the radio is to be stored for an extended period of time, it is
recommended that the batteries are removed from the radio.
Model: MWR839
Note:
When removing the batteries, locate the innermost battery and look for
the minus (-) sign located on the battery. Press down on the minus (-)
sign and the battery will be tilted out of the compartment. The rest of the
batteries can be removed easily.
Getting better Reception with External Antennas
If you have weak reception on your radio in remote areas, you may
improve your reception by using external antennas. Connect the external
FM/ weather antenna in the terminal shown in figure 24 in the pull chart.
Connect the external AM antenna as shown in figure 25, 26.
Note:
Both the FM/weather and the AM antenna are not included. For the
external FM/weather antenna, a third party antenna (ANT 100 or other
external FM/Weather antenna) can be connected for superior range
and reception. As for the AM loop antenna, you need to buy an AM loop
antenna from an electronic store. The recommended AM loop antennas
include C. Crane F5 External AM Antenna.
