Phone Line Switch
This switch acts as the switch-hook for the telephone line. The
Hang Up
position is the normal on-hook position when you are
not using the line or you are waiting for a call. When you want
to place a call, or when a call comes in, switch to the
Dial/Talk
position. When using the Handset or Wireless Interface, the
switch should remain in the
Hang Up
position at all times.
10. Power Switch
The power switch should be left in the “Off” position any time
the unit is not being used or battery drain will occur. The unit
will retain a phone line connection if the power switch is
turned off during a call.
11. Battery Test Button / LED
To test the battery, press the Battery Test button on the side
of the unit. If the LED lights, the battery is still good. The unit
may still function if the LED does not light, but there may be
significant audio distortion and a loss of level as the battery
continues to discharge. Under normal use you should get at
least 20 hours of continuous use from one fresh 9 volt alkaline
battery.
12. Wireless / Cellular Telephones
ComPack comes equipped with a built in cellular telephone
interface. This 1/4” wireless interface jack accepts a special
1/4” to 2.5 mm cable provided with the unit. This interface will
work with any wireless phone that can accept a standard 3-
conductor headset and earpiece.
Some wireless telephones have the standard 2.5 mm jack
while others have proprietary jacks. Adapters to convert the
proprietary jack to the standard 2.5 mm jack are available for
most wireless telephones through local electronic stores, their
respective telephone dealers or many internet stores.
When using the wireless interface, it is important to keep your
wireless telephone 12”-24” away from the ComPack and any
microphone or headphone cables. This will help prevent un-
wanted RF noise from entering the unit.
