Erase All 5 Channel Memories
1. With power OFF, depress the knob and turn the
unit ON. Continue to hold the knob down until the
LED starts rapidly blinking. The memory is now
erased and the unit will go into scan/search
mode.
2. Continue from step 3 above PROGRAMMING ­
ADD NEW FREQUENCY….
Multiple Transmitter Setup
When using this IFB receiver in a search mode, with
two or more transmitters running at the same time,
the receiver may stop on a false signal under the
following conditions:
• Two transmitters are on and transmitting.
• The distance from the transmitters to the IFB
receiver is less than 5 feet.
The false hits are caused by intermodulation or mixing
in the front end of the IFB receiver. At a 5 to 10 foot
distance, the two carriers are so strong at the re­
ceiver, that even this well designed front end will mix
the carriers and produce phantom frequencies. The
IFB receiver then halts its scan and stops on these
false frequencies. All receivers will 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. (Preferred)
Battery Instructions
The battery you use in the R5a 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 perpen­
dicular 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.

To open the battery
compartment door, push the
door up and away from the case
with your thumb, then swing
open.
