About Overlapping Frequency Blocks
When two frequency blocks overlap, it is possible to 
select the same frequency at the upper end of one and 
the lower end of the other. While the frequency will be 
the same, the pilot tones will be different, as indicated 
by the hex codes that appear.
In the following examples, the frequency is set to 
494.500 MHz, but one is in block 470 and the other in 
block 19. This is done intentionally to maintain compat-
ibility with receivers that tune across a single block. The 
block number and hex code must match the receiver to 
enable the correct pilot tone.

Selecting Audio Polarity (Phase)
Audio polarity can be inverted at the transmitter so the 
audio can be mixed with other microphones without 
comb filtering. The polarity can also be inverted at the 
receiver outputs.

If you are using rechargeable batteries, it is better to 
use the timer function on the receiver to monitor the 
battery life rather than the indicators on the transmitter. 
Rechargeable batteries maintain a fairly constant volt-
age across the operating time on each charge and stop 
working abruptly, so you will have little or no warning as 
they reach the end of operation. The timer is available 
on all Lectrosonics Digital Hybrid Wireless

 receivers.
