exhibit this type problem at some transmitter power level and range.
You notice false signals more with a scanning mode receiver since it
will find them all.
Prevention is simple. Do one of the following:
• Do the scan with only one transmitter on at a time. (Time consuming)
• Increase the receiver to transmitter distance to at least 10 feet.

BATTERY INSTRUCTIONS
The battery you use in the PRC-2 receiver should be a 9 Volt alkaline
or lithium, available almost everywhere. An alkaline battery will provide
up to 8 hours of operation and a lithium battery will provide up to 20
hours of operation. Carbon zinc batteries, even if marked “heavy duty”
will only provide about 2 hours of operation. Rechargeable batteries
will only operate the receiver for an hour or less. Make sure your
batteries are marked “alkaline” or “lithium.” Short battery life is almost
always caused by weak batteries or batteries of the wrong type.
A green LED corresponds to a fresh battery. The LED will change to
yellow for low battery warning then to red to indicate the need for a
fresh battery. Continued use will further deplete the battery eventually
causing the LED to automatically turn itself off and remain off until a
fresh battery is installed.
To replace the battery, open the bottom battery door cover with your
thumb, rotate the door until it is perpendicular with the case and allow
the battery to fall out of the compartment into your hand. It is difficult to
install the battery backwards. Observe the large and small holes in the
battery contact pad before inserting a new battery. Insert the contact
end of the battery first, making sure the contacts are aligned with the
holes in the contact pad, and then swing the door closed. You will feel it
snap into place when it is fully closed.
