Battery Installation Operating Instructions

To open the battery compartment, press outward on the

cover door in the direction of the arrow as shown in the

illustration. Only ﬁrm, sliding pressure is needed to open

and close the battery door. Swing the door open and take

note of the polarity marked inside showing the location of

the positive (+) and negative (-) terminals. You can also

see the large and small contact holes inside the battery

compartment with the door open.

Insert the battery correctly and close the cover by press-

ing the door closed and across, reversing the opening

procedure illustrated above. If the battery is inserted

incorrectly, the door will not close. Do not force the door

closed.

Selecting the Compatibility Mode

The UM450 can be used with Lectrosonics 400 Series

Digital Hybrid, 200 Series analog, 100 Series analog

and some non-Lectrosonics analog wireless receivers.

Contact the factory for details on the non-Lectrosonics

models that can be used. The transmitter must be set

to the operating mode of the matching receiver, which is

done using the supplied screwdriver and a battery.

NOTE: The unit is supplied from the factory as a

Digital Hybrid (400 series) transmitter.

1) Ensure the battery is good.

2) Turn off the transmitter.

3) With a small screwdriver (one is included with your

unit), set the Frequency Select Switches to CC. (for

Change, Change).

4) Power up the unit brieﬂy – just long enough for the

LED’s to light up and then turn it off.

5) Change the Frequency Select Switches to one of

the following settings:

• To set Lectrosonics 100 Series mode:

set switches to 1,1

• To set Lectrosonics 200 Series mode:

set switches to 2,2

• To set Mode 3: set switches to 3,3

(contact the factory for details)

• To set Lectrosonics Hybrid mode:

set switches to 4,4

• To set IFB mode: set switches to 5,5*

• To set Mode 6: set switches to 6,6

6) Turn the unit on, wait a couple of seconds and turn

off again.

7) Change the Frequency Select Switches to 0,0.

8) Turn on the transmitter to complete the operation.

The LEDS will blink to indicate the selected com-

patibility mode. Immediately after power up, all

LEDS will blink together red, then green, followed

by the audio level LEDs (-20 and -10) blinking to

indicate the mode.

The -20 and -10 LEDs will blink:

• Once for 100 Series mode

• Two times for 200 Series mode

• Three times for Mode 3

• Four times for Hybrid mode

• Five times for IFB mode*

• Six times for Mode 6

At powerup the transmitter will conﬁrm the current

compatibility mode with the number of blinks listed

here. This setting will remain the same until you

reset it with the procedure listed above.

*Not available on earlier units.
