Battery Installation

The UM400a can be used with Lectrosonics 400 Series
Digital Hybrid, 200 Series analog, 100 Series analog,
Lectrosonics IFB and some non-Lectrosonics analog
wireless receivers. Contact the factory for details on the
non-Lectrosonics models that can be used. The trans-
mitter must be set to the operating mode of the match-
ing receiver, which is done using the supplied screw-
driver and a battery.
NOTE: The unit is supplied from the factory as a
Digital Hybrid (400 series) transmitter.

2) Turn off the transmitter.
3) With a small screwdriver (one is included with your
unit), set the Frequency Select Switches to CC. (for

4) Power up the unit briefly – just long enough for the
LED’s to light up and then turn it off.

it 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 (if available)
• 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.
