Miscellaneous Tips

For optimal operation with external 

• 

antennas, low loss RF shielded cable 
should be used and the length of the 
cable should not exceed 10 ft. (3 m).
The receiver antennas should be kept 

• 

away from any metal surfaces whenever 
possible as they can reflect away or 
shield the incoming RF signal.
If the receiver’s volume control is set 

• 

too high, it may overdrive the input 
of the attached audio mixer, causing 
distortion. Conversely, if the output is set 
too low, the overall signal-to-noise ratio 
of the system may be reduced, causing 
noticeable hiss. If such noise occurs, 
adjust the output level of the receiver 
so that highest sound pressure level 
going into the microphone transmitter 
causes no input overload in the mixer, but 
permits the mixer level control to operate 
in the normal range (not too high and 
not too low). This provides the optimum 
signal-to-noise for the entire system.
Before inserting the batteries, ensure that 

• 

they are inserted with the correct polarity.
Before operation, confirm that the 

• 

receiver and associated transmitter are 
tuned to the same frequency group and 
channel number.
After making a receiver channel change, 

• 

ensure that the corresponding change is 
also made on the matching transmitter.
Use only brand new alkaline batteries. 

• 

Do not use “general purpose” carbon 
batteries. When batteries are weak, 
replace all the batteries at the same time. 
Do not mix new and old batteries.
Position the receiver so that it has the least 

• 

possible obstructions between it and the 
transmitter. Line-of-sight is best!
During operation, the transmitter and the 

• 

receiver should be as close as possible for 
optimum results but never closer than 3 ft. 
(1 m) as that may overload the receiver’s 
input circuitry and cause noises.

For the best operation, the receiver should 

• 

be placed at least 3 ft. (1 m) above the 
ground and 3 ft. (1 m) away from a wall or 
metal surface. The transmitter should also 
be at least 3 ft. (1 m) from the receiver. 
Keep antennas away from noise sources 
such as motors, automobiles, neon lights, 
signal processors, computers, as well as 
large metal objects.
A receiver cannot receive signals from 

• 

two or more transmitters simultaneously.
Turn the transmitter off when it is not 

• 

in use. For longest life, remove the 
batteries if the unit is not to be used for 
a long period as the transmitters draw 
a tiny residual current to maintain the 
programmed settings, even when turned 
off. Also, since batteries installed for a 
long time can sometimes corrode and/or 
leak, causing damage, it is generally 
recommended that batteries be removed 
whenever the transmitters are not 
being used.
When using the BT-1KU bodypack for 

• 

instrument use: Scratchy noises can 
sometimes occur when an electric guitar 
with dirty pots or connections is used with 
a wireless system. Therefore, the supplied 
capacitor provides first-order filtering of 
the RF signal from the cord into the guitar 
and eliminates virtually all scratchy noises. 
Should your equipment still produce 
scratchy noise, we suggest these steps 
to eliminate problems:
1) Make sure all guitar volume and tone 
pots are clean and all contacts are solid. 

This is very important.

2) Solder a 47pF capacitor across the pot 
to ground terminal of the guitar’s volume 
and tone pots to provide extra filtering.
