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.
