When the keypad is plugged in there is a 
loud pop through the speakers and the 
keypad does not work.

Improperly wired CAT5 cable.

Check that you are using the 568A or B 
wiring standard (see Section I: Crimping 
CAT5 wire). The best way to know is to 
use a CAT5 tester.

When the keypad is plugged in, it just 
flashes and has no functionality.

Assigning duplicate addresses to multiple 
keypads.

Each keypad must have a unique address 
set with the Zone Address rotary switch 
located on the back of the keypad (see 
Section VI, Installing the Simplese 
keypads, page 10).

The keypad or keypads will not change 
source independently. They all change 
source at the same time.

Source Grouping is turned on.

Each keypad has the ability to be set as a 
source group or remain independent. Use 
the Mute button and the Source 3 button 
to turn the Source Group feature on and 
off (see Section VI, Source Grouping, 
page 11).

All the keypads change when a source is 
selected on only one.

The keypads are set for Source Grouping.

Pressing the MUTE and Source 3 button 
simultaneously sets the Source Grouping 
feature. This will cause multiple keypads 
to always share the same source (see 
Section VI, Zone EQ and Source Grouping, 
page 11).

With the keypads plugged in, the POWER 
LED on the front of the amplifier will not 
turn on.

One or more improperly wired CAT5 cables.

Make sure that the amplifier is plugged 
into a reliable power source. Test that the 
POWER LED on the amplifier turns on 
when the Allport Cable is unplugged and 
plugged in again. Next, unplug all the 
CAT5 cables from the Allport and plug 
them back in one at a time until the bad 
cable(s) is discovered.
