appliance. If using a cart, be careful when moving the cart/appliance combination to avoid injury from tipover (Figure 1).
13) Unplug this appliance during lightning storms or when unused for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required when the appliance has been damaged
in any way, for example, the power-supply cord or plug is damaged, liquid has been spilled or objects have
fallen inside the appliance, the appliance has been exposed to rain or moisture, does not operate normally,
or has been dropped.
WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture.

Introduction
We have designed the Lanen GB21 and UHF21 systems as wireless accessories for your electric
and/or bass guitar (GB21 receiver) and your Prodipe Series 21 mic (UHF21 transmitter). Both
UHF wireless systems use an extremely stable phase-locked loop (PLL) circuit to remove
unwanted jitter. They also offer dual antenna/dual receiver circuit analogue wireless
transmission (True Diversity). The power consumption for the transmitter and the receiver has
been calibrated as accurately as possible to give you a generous battery life. Before leaving the
factory, each of our products is meticulously tested by our quality control department.
Statement of Compliance
The equipment complies with the essential requirements of the European Directive R&TTE 99/5/EC*.
Before using any of the devices, please observe all applicable country-specific regulations. This radio
equipment is intended for use in musical professional entertainment and similar activities.

Configuring the transmission channels
Switch on the receiver and the bodypack transmitter by pressing and holding the receiver
POWER button (7) and the bodypack POWER button (6). Open the bodypack battery
compartment and locate the infrared sensor:
Channel selection is automatic. Ensure that the bodypack infrared sensor is in line with the
receiver (about 10cm distance). Press quickly on the receiver SCAN IR button and the
synchronisation will start automatically. Once the automatic scan has finished, the channel will
be displayed on the channel display screen and the RF reception indicator light will come on.
You can also manually select a channel by pressing and holding the CHANNEL button (4) until one
of either number on the channel display flashes. Select the desired number with the CHANNEL
button. Then confirm your selection by pressing the POWER button (7) and repeat the process
for the second number.
If no selection is made after 10 flashes, the receiver will automatically stop the channel
selection process.
Using the equipment
Position the receiver at least one metre above floor level and one metre from walls. In addition,
ensure that the receiver is as far as possible from any other source of electromagnetic radiation.
Connect the Series 21 mic mini XLR or the active extension cable with jack to the bodypack
input connector (7).
Adjusting the bodypack attenuation control for UHF21:
• Normal volume instrument e.g. violin:
• High volume instrument e.g. double bass:
• Very high volume instrument e.g. trumpet:
- 0dB
-10dB
-20dB
Adjusting the bodypack attenuation control for UHF21:
• Bass guitar:
- 0dB
• Active bass guitar: -10dB
• Electric guitar:
-10dB or -20dB
Adjust the volume control at the rear of the receiver to your preferred level.

Safety and guarantee
• You should switch the transmitter off before changing the batteries.
• Loss of signal or extraneous noise (‘wind’) could be caused by a low battery or too large a
gap between the transmitter and receiver. First check and test the batteries. If the
batteries are fine, readjust the receiver antennae or change the channel.
• To avoid any deterioration in the RF signal, the receiver should not be placed in a corner.
• The receiver antennae should not be near a metallic surface.
• The receiver should be placed as far away as possible from any digital devices (computer,
phone, etc.).
• If you have several GB21s/UHF21s, you should ensure that the antennae do not touch or
pass in front of each other.
• The transmitter should always be switched off after use and the batteries removed.
• The transmitter and receiver should be kept in a dry, light-free location if not being used
for long periods.
Prodipe and its distributors decline all responsibility for any damage caused to the unit in
the event that the above safety precautions are not followed.
