Troubleshooting

Why are the Talk keys flashing
periodically?
The Call functionality on my analog
beltpack is no longer working.
I cannot pass audio to wired /
wireless intercom equipment over
the Two-wire module.
Why do I hear an echo when
interfacing via a two-wire audio
port?
Echo occurs even after Two wire
module has been auto-nulled.
There is no audio or only partial
audio (send or receive, but not
both) between other audio systems
/ sources connected over four-
wire.
Line 1 (or Line 2) LED is blinking
red.
Line 1 (or Line 2) LED is steady red
and one or more Beltpack has no
bars showing up for signal
strength.

Issue
Flashing Talk keys may indicate a fault in the cable.
Check the cable for short-circuit conditions and replace if
necessary.
HelixNet Partyline operates at different voltage levels than
analog two-wire Partyline systems.
The analog beltpack may have been damaged if it was
connected to a HelixNet Main Station Partyline port.
Contact Clear-Com for repair options.
Two-wire option modules require an external power
supply. See
Run auto-nulling.
Ensure that all unused Talk keys in the system are
unlatched.
Check to ensure all open Talk keys are not latched and re-
null.
Check the cable used to connect the equipment.
HelixNet to Eclipse four-wire connections only require a
standard CAT cable, whereas other four-wire connections
(to Tempest™, CellCom / FreeSpeak, and other systems)
require an audio crossover cable. See:

Powerline. Look at the Diagnostics->Powerlines-
