Reset Button 
Should your 74-200 become unresponsive to button entries or 
does not work properly, a reset button has been added. This 
button is accessed from the bottom of the 74-200. To activate this 
function, use a long object such as a straightened paper clip. 
Carefully insert this into the small hole marked “Reset”. When 
you press the button inside the 74-200, you will feel a click. This 
resets the Clock, Calendar and alarm time. This reset will not 
affect the “SAME” codes entered. 
  
						

							 
 22 Back Light of the Display 
When the AC to DC adapter is used the display back light is 
always on. When only the backup battery is used to power your 
74-200, pressing and releasing the “SNOOZE” button will turn on 
the back light for about 5 seconds. 
 
Button press Beeps 
When a button is pressed with the “Max / Volume / Off” switch 
ON, the 74-200 emits a beep sound. One beep represents that the 
74-200 has received a command and has taken effective action. 
Two beeps represents the command is not valid (wrong button 
pressed) and no action is taken. 
 
TROUBLESHOOTING 
 
Problem Suggestion(s) No power. Ensure that the wall power 
adapter is connected to AC 
power, that the cord to the radio 
is securely seated in the radio 
and that a fresh back-up battery 
is installed (if AC power has 
failed). No sound. Check VOLUME setting No weather broadcast when 
you press WEATHER Ensure that telescoping antenna 
is fully extended.  
						

							 
 23  
 If you are using an external 
antenna, ensure that it is connected properly.                        Ensure that the radio is set to 
the NOAA weather channel in 
use in your area. Contact 
NOAA to ensure they are 
presently broadcasting. One or more FIPS codes are 
stored in memory but the radio 
responds to alerts for areas 
other than those for the codes 
stored. Ensure that the all signals code 
(999999) is not stored in a 
memory. The radio is not responding 
properly to NWS weather alert 
broadcasts Ensure that you have 
programmed the correct FIPS 
code(s) into the radio’s 
memory. Be sure that “999999 
is not programmed with any 
other “FIPS codes  If you desire to hear the alert or 
operate a device from 
EXT.ALERT jack ensure that 
display shows WEATHER 
ALERT ON.  If not, press 
ALERT.   
						

							 
 24 NOTES AND 
MAINTENANCE 
 
1. The typical weather (162MHz) reception distance will 
range from 25-50 miles depending on your location and 
conditions of weather, terrain, etc. Also, some Weather Stations 
operate at much higher power levels than others and have their 
transmitting towers on the top of high buildings or hills. For better 
reception from greater distances, an external antenna can be used. 
To use an external antenna, you must have an antenna with an 
RCA phono plug or an adapter to RCA phono plug to connect 
into the back of the 74-200. If reception in your area is not good, 
check with your local dealer for assistance and ask about typical 
reception range in your area. Also try different locations in your 
home or office to find a place of good reception. A location near a 
window is a good starting place. 
2. If Weather Stations cannot be heard on any channel, 
contact your local National Weather Service office to verify that 
the station is on the air and also verify the CHANNEL 
(Frequency) and location of the weather station. 
3. All National Weather Service stations periodically 
transmit an Alert test signal. Some broadcast only once a week 
and others more often. You can always find out when the test 
signal is broadcast by calling the U.S. Weather Services phone 
number for your local NOAA station. 
4. Mobile home reception is difficult due to the metallic  
						

							 
 25 structure preventing reception. Put your 74-200 near a window. If 
this doesnt provide reasonable reception-then an outside antenna 
must be used.  One suggested antenna is the Midland 18-259W 
VHF through-glass antenna. This antenna must be used on single 
pane windows only. 
 
12 VOLT OPERATION 
Your 74-200 can be powered from any 12-Volt CAR-TRUCK-
RV or BOAT battery. An optional (Model 18-235) power cord 
adapter is available from Midland or your local dealer.
