6. GENERAL INFORMATION

Always make all other connections before plugging the
DC power supply into an AC power outlet

Do not keep the devices in places of very high temperature
or humidity

For optimum reception and maximum operating distance aim
for open space between receiver and transmitter

For optimum performance use devices at least 50cm away
from known interference sources

For best pick up pattern grip the hand held microphone
around the middle of its body

Remove the batteries when transmitters are not likely to be
used for some time

When replacement batteries are needed always change both
for new ones at the same time

CW9004T - CW9005T - CW9006T SWITCHING INSTRUCTIONS

The following instructions are a step to step guide of how you can programme the switch to the
function you require:

1. Whilst holding down the function switch, power up the base by switching on the power 

switch located on the underside of the base.This enables you to enter programming 
mode. Note both bases require 9 to 48 volts phantom power to operate.

2. You will notice the LED flashes on and off for approximately 2 seconds to tell you that 

programming mode has been selected.

3. At each stage of programming the base will tell you what functions have already been 

stored by the LED flashing the appropriate numbers of times. See the table below for a 
quick reference guide.

PTM (Normally On)

By pressing the switch once programme option 1 shall be selected and the LED will flash
according to which option is stored (either once for Momentary or twice for Latching) and
likewise for programme option 2 for PTT or PTM.

You are able to change the switching operation by following the step by step guide.

Latching (Normally On)

This is the default setting, the switch has a latching operation and the microphone is live as soon
as the base is powered. Should the default setting be cleared perform the following actions:

1. Press the switch once the LED will flash once, then press the switch twice the LED will 

flash twice. Once you have performed this step the switch is set for Latching operation.

2. For Normally On press the switch twice, the LED will flash twice, then again press the 

switch twice the LED will flash twice. Wait for approximately 5 seconds and the switch 
function will be set into the bases memory.

Latching (Normally Off)

The microphone requires the switch to be pressed to become live. For programming follow step
one from above and then for normally off press the switch twice, the LED will flash twice, then
press the switch once the LED will flash once. Wait for approximately 5 seconds and the switch
function will set into the bases memory.

Push to Talk

In this function the switch needs to pressed and held for the microphone to be live.

1. Press the switch once the LED will flash once, then again press the switch once the LED 

will flash once. Once you have performed this step the switch is set for push operation.

2. For PTT press the switch twice the LED will flash twice, then press the switch once the

LED will flash once. Wait for approximately 5 seconds and the switch function will be set
into the bases memory.

Push to Mute

In this function the microphone is live until the switch is pressed and held down.

1. Press the switch once the LED will flash once, the again press the switch once the LED 

will flash once. Once you have performed this step the switch is set for push operations.

2. For PTM press the switch twice the LED will flash twice, then press the switch twice the 

LED will flash twice. Wait for approximately 5 seconds and the switch function will be set 
into the base memory.

Please allow time for the LED to flash between each stage of programming and also at each stage
the interval between pressing the switch should be no more than one second.

Should for any reason you wish to start over remove to the base.

6. GENERAL INFORMATION

Always make all other connections before plugging the
DC power supply into an AC power outlet

Do not keep the devices in places of very high temperature
or humidity

For optimum reception and maximum operating distance aim
for open space between receiver and transmitter

For optimum performance use devices at least 50cm away
from known interference sources

For best pick up pattern grip the hand held microphone
around the middle of its body

Remove the batteries when transmitters are not likely to be
used for some time

When replacement batteries are needed always change both
for new ones at the same time
