Community Messenger Unit
Information:
Data Signal:
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.
Volume Control:
The standard unit has one volume control for the speaker.
Power Supply:
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:
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.
