DO NOT connect the E101 with non-approved headsets or Control
Stations.
DO NOT use the E101 in the rain or in damp situations.

1 INTRODUCTION
The Jands Ezicom is a closed circuit headset intercom system which provides clear twoway communications even in high noise environments. A basic Ezicom system consists
of one E401 master station connected to a number of remote E101 belt packs.
Ezicom components are interconnected with standard two-conductor shielded microphone cable fitted with three-pin XLR style connectors. One wire in the cable caries DC
power from the master station to the remote belt packs; the other wire carries audio sig-
nals and superimposed “call” signals for visual signalling. The cable shield acts as the
common ground-return.
The Ezicom cable transmission system is fully compatible with industry-standard head-
set intercom systems, allowing master stations and belt packs to be freely interchanged
with other brand components without degrading performance.
1.1 Features
High durability extruded aluminium case with custom moulded end caps;
Bridge-mode amplifier for high output power;
Large backlit buttons are easily identified in dark or low light situations;
Remote Mic disable compatible.

3 CONNECTIONS
The Ezicom and compatible communications systems use 3 pin shielded microphone
cables for all interconnecting links. Only one power source (usually a Master) should be
used in a system.
Ensure all plugs are firmly seated in their sockets with the latches engaged. If possible
make all connections before switching the power to the master station on - making connections while the power is on may disrupt other users and/or create clicks, pops, buzz,
or other extraneous sounds.
4 OPERATION
Once the system has been plugged in and switched on, both the Call and Microphone
switches will glow blue indicating power is available. Turn the volume control to minimum
(fully anticlockwise) before putting the headset on.
Slowly increase volume by turning the control clockwise. If there is signal present, for
example there is program signal or a conversation is taking place, adjust the control until
a comfortable level is achieved. If there is no signal present, turn the volume control
back down, press the microphone switch to turn the headset mic on, then speak normally as the volume level is increased until a comfortable level is achieved. Turn off the
microphone.
The volume level may require adjustment over time as more users come on line or the
ambient noise level changes. Excessive headphone level should be avoided.
The Ezicom system is a party line system, which means all users in the system can hear
the input from all open mics. For this reason:
Leave the microphone switched off unless required.
Ensure the microphone is turned off when the headset is taken off or the E101 is
unplugged from the system.
Press the call switch to attract the attention of other users in the system who may not
have their headphones on.
5 DISCONNECTING THE UNIT
Turn off the microphone before disconnecting the E101. If possible switch power off to
the system master station before making any disconnections.
Firmly press the release buttons to remove plugs from sockets.
