Power On/Off Switch
A Power On/Off switch located on the outside bottom
of the unit turns the unit on and off. The function of the
Power On/Off Switch can also be changed so it also
operates as an audio mute switch. In this configuration,
the Power LED doubles as a battery status indicator (in
the unmute or On position) and an audio mute/unmute
indicator (in the muted or Off position). (See Operating
Instructions, Power Switch Function Selection.) These
functions are illustrated in the chart below:
If the UT Power On/Off Switch has been configured
for Audio Mute Mode, it is still possible to turn off the
transmitter without removing the battery. This is done
by placing the switch in the On position, then toggling
the switch between the On and Off position three times
in less than five seconds, i.e., On (Starting Position)­
Off-On-Off-On-Off.
The user-selected configuration of the Power On/Off
switch is stored in the unit’s memory and persists until
reconfigured by the user.

Power LED
Whether in normal, mute or locked mode, the Power
LED will indicate the battery level when the unit is pow­
ered up.
The Power LED
indicates the battery
status when the unit
is powered up with
the Power On/Off
switch configured for
normal operation.
The Power LED
glows green when
the battery is good.
The color changes
to red when there
is about 30 minutes
of operation left with the recommended lithium battery.
(An alkaline battery will have about 20 minutes of life
left.) When the LED begins to blink red, there are only
a few minutes of life left in the battery. The Power LED
blinks red for a short period when the transmitter is con­
figured for Normal Mode and the Power On/Off switch
is set to Off. At the end of the power off sequence, then
Power LED goes out.

Controls and Functions
NOTE: A NiMH battery gives little or no warning
when it is depleted. If you use NiMH batteries
in the UT, we recommend trying fully charged
batteries first, noting the length of time that the
batteries will run the unit and in the future use
somewhat less than that time to determine when
the battery needs to be replaced.
When first tinstalled, a weak battery will sometimes
cause the Power LED to glow green, but will soon dis­
charge to the point where the LED will blink red or shut
off completely.
When Power On/Off switch is configured for Audio Mute
Mode, the Power LED indicates battery status when the
switch is set to On. However, when the Power On/Off
swtich is configured for Audio Mute Mode and set to Off,
the Power LED will slowly double blink green to indicate
that the unit’s audio is muted. (See Operating Instruc­
tions, Power Switch Function Selection.)
Compatibility Modes
The Power LED is used to indicate Compatibility Mode.
To identify the current Compatibility Mode, as part of the
powerup sequence, the Power LED will blink:
• Once for 100 Series mode
• Two times for 200 Series mode
• Three times for Mode 3*
• Four times for 400 Series mode
• Five times for IFB Series mode
*This mode works with analog receivers from other
manufacturers. Contact Lectrosonics for a complete list
of non-Lectrosonics compatible receivers.
