Changing Batteries

  • Expected life for an Alkaline battery is approximately 8 hours.
  • When the transmitter light glows red, the batteries should be changed immediately, as shown.

Wearing the Bodypack Transmitter

Clip the transmitter to a belt or slide a guitar strap through the transmitter clip as shown.

For best results, slide the transmitter until the belt is pressed against the base of the clip.

Adjusting Gain


Three gain settings are available on the PGX1. Choose the appropriate setting for your instrument.

  • mic: Microphone (higher amplification)
  • 0: Guitar with passive pickups (medium amplification)
  • –10: Guitar with active pickups (lower amplification)

If the receiver LED indicates the input volume is overloading the receiver, try switching the gain to a lower setting.


Access the gain adjustment switch by unscrewing the head of the microphone.

Two gain settings are available on the PGX2. Use the tip of a pen or a small screwdriver to move the switch.

  • 0dB: For quiet to normal vocal performance.
  • –10dB: Use only if audio is distorted due to high voal levels.

Single System Setup

1 Scan

Use the scan feature on the receiver to find a clear channel.

a LED screen displays current channel

b press channel button to scan for a clear channel

c system scans for the channel with the least interference

2 Synchronize

Synchronize the transmitter to the receiver by aligning the infrared (IR) ports and pressing the sync button. Make sure the IR ports are closely aligned.

After a successful sync, the transmitter LED momentarily flashes red and the receiver ready light illuminates.

Multiple System Setup

Use the following steps to ensure the best performance when installing multiple wireless systems at the same location.

  1. Turn all receivers on and all transmitters off.
  2. Note: Turn on any other digital equipment that could cause interference during the performance so it will be detected during the frequency scans in the following steps.

  3. Make sure the group number is the same for all receivers (see Manual Group Selection).
  4. Perform a scan using the first receiver.
  5. Turn on the first transmitter and sync it to the receiver.
  6. Repeat for each system.
  • Important: After syncing each transmitter, leave it on so that scans from the other receivers will not select that channel.
  • Be sure only one transmitter IR port is exposed when synchronizing each system.

Manual Channel and Group Selection (receiver only)

Using the receiver to scan for a channel is the best way to find the best frequency for your system. However, for multiple system setup, you may need to manually set the group number.

  1. Press and hold the channel button.
  2. Hold the button until the channel or group display begins flashing.
  3. Release and press the button again to advance the setting. At the desired channel or group number, wait for the flashing to stop. This activates the new setting.
  4. Transfer the new frequency setting to the transmitter using the automatic sync function.

Locking and Unlocking Controls

Locking the system controls prevents accidental muting or channel adjustment 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)


To lock the channel: Hold the channel button until the numbers flash (~10 seconds)

To unlock the channel: Hold the channel button until the numbers flash (~5 seconds)

Information to the user

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna.
  • Increase the separation between the equipment and the receiver.
  • Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
  • Consult the dealer or an experienced radio/TV technician for help.

Note: EMC conformance testing is based on the use of supplied and recommended cable types. The use of other cable types may degrade EMC performance.

Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
