Perform a sound check. Use the

audio gain control located on the

side (FP1) or front (FP3) of the

unit to adjust the gain up (+) or

down (−) until desired level is

reached.
FP3 only: Adjust so the audio

input level indicator flickers yellow

at peak sound levels.

The handheld transmitter normally

does not require adjustment and

should be left at 0dB for most appli-

cations. Only use the –10dB setting for

loud singing or other high SPL applica-

tions if there is noticable distortion.

Access the gain adjustment switch

by unscrewing the head of the

microphone. Use the tip of a pen

or a small screwdriver to move the

switch:

0dB: For normal use.

–10dB: Use only if audio distorts due to high SPL levels.

1. Perform a group scan: 

Press and hold the scan button for 3 seconds. After the scan com-

pletes, the new group and channel is automatically activated and

saved.

2. Synchronize the transmitter: 

Align the transmitter and receiver infrared (IR) ports and press the

sync button.
After a successful sync, the transmitter LED momentarily flashes and

the blue RF LED illuminates.

Use the following steps to ensure the best performance when using mul-

tiple wireless systems at the same location.
1. Turn all receivers on and all transmitters off.

Note: Turn on any other digital equipment that could cause interfer-

ence during the performance so it will be detected during the frequen-

cy scans in the following steps.

2. Perform a group scan using the first receiver by pressing and holding

the scan button for 3 seconds.

3. Turn on the first transmitter and sync it to the receiver.
For each additional system: 
1. Manually set the group number to match the first receiver (see Manual

Group and Channel Selection).

2. Perform a channel scan by pressing the scan button.
3. Sync the transmitter to the receiver.
Important: After syncing each transmitter, leave it on so that scans from

the other receivers do not select that channel. Be sure only one transmit-

ter IR port is exposed when synchronizing each system.

Important: Most single-system applications do not require manual group

or channel settings--use an automatic frequency scan instead. However,

it may be useful for some applications, such as to tune to and record au-

dio directly from a microphone in a compatible wireless installation.
To set the group: 
1. Press the scan and sync buttons simultaneously. The GROUP display

flashes.

2. Press the sync button to change the group number.
3. Press scan to accept the selected group.
4. Press scan again to save and exit.
5. If desired, perform a channel scan to select an open channel in that

group.

To set the channel: 
1. Press the scan and sync buttons simultaneously. The GROUP display

flashes.

2. Press scan to move to the channel setting. The CHANNEL number

flashes.

3. Press the sync button to advance to the desired channel number.
4. Press scan to save and exit.
Note: Remember to sync the transmitter to the receiver.

If you experience RF interference, switch to a new channel using the

channel or group scan.
Channel scan: Press the scan button on the receiver. Switches to new

channel in the same group.
Group scan: Press and hold the scan button for 3 seconds. Finds a new

group and selects an open channel in that group. (Do not use in multiple

system setups unless all systems are moved to the same group.)

Locking the transmitter prevents accidental changes during

performances.
To lock the controls: With the transmitter off, hold the power button

down until the green LED flashes (~5 seconds)
To unlock the controls: With the transmitter on, hold the power button

down until the green LED flashes (~5 seconds)
