Using the XP40iw Wireless Microphone
The basic procedure for setting up and using your XP40iw Wireless System takes
only a few minutes:
1. For the XP40iw system to work correctly, both the receiver and transmitter
must be set to the same channel. Remove all packing materials (save them in case
of need for future service) and check to make sure that the supplied receiver and
transmitter are set to the same channel. If these channels do not match, contact
your Samson Technical Support at 1-800-372-6766.
2. Physically place the XP40iw where it will be used (the general rule of thumb is
to maintain "line of sight" between the receiver and transmitter so that the person
using the microphone can see the XP40iw).
3. Make sure the Power on-off switch in your HT5 handheld transmitter is set to
"Off. "
4. On the HT5 handheld transmitter, unscrew the bottom section of the
microphone by turning it counterclockwise and then slide it off.
5. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care
to observe the polarity markings.
6. Turn the WIRELESS LEVEL knob on the XP40iw completely counterclockwise.
Connect the supplied AC adapter to the DC Input on the rear panel of the XP40iw,
then plug the adapter into any standard AC outlet. Press the rear panel Power
switch to turn on the XP40iw.
7. Turn on the power to the HT5 transmitter (using its Power on-off switch); all
three Battery strength LEDs will light if the battery is sufficiently strong. At this
point, the RF LED on the rear panel of the receiver will light. Replace the bottom
section of the HT5 handheld microphone by sliding it on and then screwing it back
on. Leave the transmitter off for the moment.
8. Now it's time to set the audio level. Make sure that your HT5 transmitter is
unmuted by setting its Audio switch to "On. " Speak or sing into the mic at a normal
performance level and raise the WIRELESS LEVEL control until the desired level is
reached.
Bear in mind also that the HT5 microphone is unidirectional which means it picks
up sound from the front of the mic and rejects sound from the rear. This will help
