Setting Up and Using Your
UM1 System
The basic procedure for setting up and using your UM1 Wireless System takes only a few
minutes:
1. For the UM1 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 UM1 receiver and UT1L, UT1G or UH1
transmitter are set to the same channel. If these channels do not match, contact your
distributor or, if purchased in the United States, Samson Technical Support at
1-800-372-6766.
2a. If you are using a 9-volt battery to power the UM1, press gently down on the battery
door release (on the front of the UM1, on the word “Open”) and swing the door open in
order to access the battery compartment . Note that the door is hinged and is not
intended to be removed from the receiver case. Insert a 9-volt battery, being careful to
observe the polarity markings.
Warning: Reversing the battery polarity may cause
permanent damage to your receiver
. Turn the power switch “On” and set the Meter
switch to “BATTERY.” The green “HIGH” meter LED will light if the battery is sufficiently
strong. Once you’ve verified battery strength, turn the power switch “Off” again.
2b. If you are using the optional Samson AC300R adapter or your video camera’s 12-volt
power supply to power the UM1, connect it to the UM1 DC input jack. On the front of the
UM1, press gently down on the battery door release (on the word “Open”) and swing the
door open note that the door is hinged and is not intended to be removed from the
receiver case). Make sure the power switch is set to “Off.”
3a. If your system contains a UT1L or UT1G belt-pack transmitter, locate the battery
cover release and slide the lever down to open the battery door, which is hinged and not
intended to be removed from the transmitter case. Please use care when opening this
door as undue force will destroy the hinge.
3b. If your system contains a UH1 handheld transmitter, unscrew the bottom section of
the microphone by turning it counterclockwise and then slide it off.
4. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to
observe the polarity markings. If you are using a UT1L or UT1G belt-pack transmitter,
gently replace the battery door by swinging it up and pressing until it clicks. If you are
using a UH1 handheld transmitter, replace the bottom section of the microphone by sliding
it on and then screwing it back on. Whichever transmitter you are using, leave it off for the
moment.
5. Next, make the physical cable connection between the output of your UM1 receiver
and the audio input of your video camera or audio amplifier or mixer, being careful to set
the Audio Output Level switch so that the signal is strong but not distorting. Normally, it
should be set to the “-30” position when connecting to a mic-level input and to the “-20” or
“-10” position when connecting to a line-level input. If required, both the balanced and
unbalanced outputs can be used simultaneously. Leave your amplifier (and/or mixer) off
at this time.
6. Turn the power to the UM1 “On” and close the battery door.
7. Extend both “A” and “B” antennas from the UM1 and place both in a vertical position.
8. Turn on the power to the UT1L, UT1G or UH1 transmitter; the green “HIGH” Battery
strength LED will light if the battery is sufficiently strong. At this point, either the “A” or “B”
orange LED on the front of the UM1 will light (depending upon which antenna is receiving
the stronger signal).
