ComPack General Operation
1. Connect your microphone (and/or line input) and headphones to the
input and output jacks on ComPack.
2. Connect the jack marked "phone line" to any standard analog telephone
line
Or disconnect the handset on an existing telephone and plug the coily
cord into the "PBX handset interface" jack on ComPack
Or using the supplied cable, connect the "wireless phone headset" jack
to the 2.5 mm earpiece jack on your cellular phone.
3. Turn on the power switch, flip the phone line switch to dial/talk*, flip the
keypad switch to on*, and dial your call.
*When using the wireless phone or PBX handset interface, the phone line
switch should be left in the Hang Up position and the Keypad switch should
be in the off position. All Dialing and answering of calls in these modes must
be done from the telephone itself.
ComPack Telecom / Intercom Link
ComPack also functions as a simple "no-frills" telecom link for your beltpack
intercom system. ComPack will provide bi-directional audio on pin 3 of the
male XLR jack to any industry standard intercom beltpack system. ComPack
does not provide power over this XLR jack nor does it require power from the
loop. ComPack will not recognize a "call" signal generated by your intercom
system or provide one.
1. Slide the Male XLR selector switch to the Com Link position. This switch
is located within a small hole near the power jack. Accessing the switch
can be done using a small blade screwdriver, or other such object, in-
serted into the opening. The left position (towards the XLR jacks) desig-
nates Line Output. The right position (towards the volume controls) desig-
nates Com Link. The factory default position of this switch is Line Output.
2. Connect your beltpack intercom XLR cable to the ComPack Com Link
Male XLR jack. The XLR jack is wired as:
Pin 1 = Ground
Pin 2 = Com in
Pin 3 = Com out
Your intercom headset should remain plugged into your beltpack system,
3.
not directly into ComPack.
