Appendix: Best Practices
This appendix provides best practices to help ensure successful configuration
and operation of the 3M™ Wireless Communication System Model XT-1.
PreAmp Setting
Set the PreAmp gain setting according to the type of wiring you are using:
•
If you are using the provided 3M Microphone and the 20 AWG cable,
set the PreAmp gain setting to 5.
•
If an 18 AWG cable is used, set the PreAmp gain setting to 3.
•
If a 22 AWG cable is used, set the PreAmp gain setting to 7.
Volume Control
Here are some guidelines:
•
If you are using the provided 3M Microphone and you set the PreAmp
gain setting to a value over 10, you could cause distortion and echoes
on the inbound channel.
•
If the customer wants the inbound communication at a higher volume
level, set the inbound volume control to a higher level, or show the
customer how to increase the headset volume.
•
Do not increase the volume using the PreAmp gain. The PreAmp is
designed to optimize the 3M™ Wireless Communication System
Model XT-1 and the Microphone and should not be used to increase the
volume level.
Optimizing the Installation
The following steps may reduce the possibility of customer complaints and may
decrease your installation time:
•
Power Supply Mounting – mount the power supply in a safe place
where it will not get disconnected.
•
Use strain relief on all connections – the 3M™ Wireless
Communication System Model XT-1 was designed so that all
connections would be strain relieved and therefore minimizing the
chance of a connector being disconnected.
•
Use an Uninterruptible Power Supply (UPS) – adding a UPS will make
the 3M™ Wireless Communication System Model XT-1 more reliable
by increasing uptime as providing a cleaner power source.
•
Use a Pre-install Checklist.
•
Use an Installation Checklist.
•
Remove the Microphone Cover (Adhesive disk protecting the front of
the microphone).
