Community Messenger Unit
If the home radio station is off the air for 3 minutes, the
display screen will show “Searching for Signal.” It will scan for
and lock onto an appropriate data signal and then continue to
check back with the home station once a minute until it is
back on the air.
The standard unit has one volume control for the speaker.
The power supply is a 12 volt AC (alternating current) power
supply. It is not recommended that a dc (direct current )
power supply be used because the electrical line between the
AC outlet and the unit tends to pick up more RF (radio
frequency) noise. A 12 volt DC power supply will work but is
not recommended. Use of a 12 volt auto cigarette supply in
case of emergencies is acceptable.
Batteries are installed in the bottom of the unit. Remove the
plastic cover from the bottom of the case and replace the six
1.5 volt AA batteries. Battery power is automatically used
when the unit is unplugged unless the batteries are removed.
The unit will generally run 24 hours with the battery pack
when supplied with fresh batteries. The batteries are for back up only. Don’t run your unit on
battery power unless you want to buy lots of batteries. This
unit contains a computer chip and will use batteries quickly.
Batteries should be checked often to make sure they are fresh. If the screen displays the message shown below or if the unit
resets, replace all the batteries.
To test batteries, turn the audio on full, with the unit un-plugged.
If the LED or display seems to flicker or if the audio
fades, replace all the batteries.
