Frequently Asked Questions - GB 40 FLEXX GUITARBUG AKG

How to install the battery in the GB 40 FLEXX transmitter?

Push the battery compartment cover latch downward, remove the cover. Insert a 1.5 V AAA battery respecting the indicated polarity. Close the cover until it clicks. The foam pad inside the cover keeps the battery in place; do not remove it.

What does the red LED on the transmitter mean?

The red LED indicates low battery. With a standard battery, about 1 hour of battery life remains. With a NiMH rechargeable battery, the indicator turns red 15 to 20 minutes before full depletion. Replace or recharge promptly.

How to adjust the audio input level of the transmitter?

Use the supplied screwdriver to turn the input potentiometer (mark 4). Start at the middle position, then adjust while playing: turn counterclockwise if distortion, clockwise if insufficient volume.

How to stabilize the transmitter on the instrument?

Use the two self-adhesive discs supplied. Stick one on the back of the transmitter (after removing the protective film) and the other on the instrument where the transmitter rests. This prevents unwanted movement.

What to do if my guitar's output jack is recessed (flush-mounted)?

Use the long adapter supplied. Unscrew the jack plug from the transmitter, screw the adapter onto the transmitter's female jack, then insert the assembly into the instrument's recessed jack.

How to change the carrier frequency of the transmitter?

The transmitter has a frequency selector with three positions (1, 2, 3). Make sure the SR 40 FLEXX receiver is set to the same frequency. The label on the back of the transmitter indicates the frequencies for each position.

What is the battery life with a rechargeable battery?

With a 1.2 V NiMH rechargeable battery (type SANYO HR-4U 650 mAh or Panasonic Rechargeable PRO+ 550 mAh), typical battery life is more than 6 hours. The red LED turns on 15-20 minutes before depletion.

How to clean the GB 40 FLEXX transmitter?

Clean the housing with a slightly damp cloth (clean water). Do not use abrasive products or solvents. Make sure the transmitter is turned off and the battery removed before cleaning.

What to do if the LED does not light up at all when turning on?

This means the battery is depleted or incorrectly installed. Check polarity and replace with a new battery. If the problem persists, contact your AKG dealer.

How to properly attach the transmitter to a guitar or bass?

Rotate the swiveling jack plug 90° relative to the housing, then fully insert it into the instrument's output jack. The built-in spring pulls the transmitter against the instrument for a secure fit. Avoid pressing the instrument against the transmitter.

2.4 Description

The GB 40 FLEXX is a WMS 40 microtools Series miniature transmitter that has been specifically designed for electric guitars and basses but is also suited for keyboards.

The transmitter features a permanently attached, swiveling 1/4 jack plug that allows you to plug the transmitter directly into the output jack of your instrument. A built-in spring presses the transmitter against the instrument to hold it securely in place. The bottom of the transmitter is fitted with a soft plastic pad that will leave no trace on the instrument.

The supplied Velcro pads allow you to attach the transmitter even more firmly to the instrument.

Operating in the 660 MHz to 865 MHz UHF range, the GB 40 FLEXX provides three selectable, quartz stabilized carrier frequencies within the 3-MHz-wide frequency band you specified at the time of ordering and uses a permanently attached flexible antenna.

You can replace the black battery cover with one of the supplied replacement covers.

2.5 Controls (refer to fig. 1 on page 13)

1 ON/MUTE/OFF: This slide switch provides three positions:

ON: Power to the transmitter is on.

M: The signal delivered by the microphone is muted while power and the RF carrier frequency remain on. This prevents the receiver responding to interference from other transmitters.

OFF: Power to the transmitter is off.

2 Battery compartment for one 1.5-V AAA size battery (supplied).
