determined by turning the equipment on and off, the user is encouraged to try to correct the interference
by one or more of the following measures:
•
Reorient or relocate the antenna.
•
Increase the separation between the equipment and receiver.
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•
Check if the affected unit complies with the EMC limits for immunity, (CE-labelled). If not,
address the problem with the manufacturer or supplier. All electrical products sold in the
EC must be approved for immunity against electromagnetic fields, high voltage flashes, and
radio interference.
•
Consult the dealer or an experienced radio/TV technician for help.

Carefully open the shipping carton and check for any noticeable damage. Every Lab.gruppen amplifier
is tested and inspected before leaving the factory and should arrive in perfect condition. If found to be
damaged, notify the shipping company immediately. Only the consignee may institute a claim with the
carrier for damage incurred during shipping. Be sure to save the carton and packing materials for the
carrier's inspection.
It is also advisable to save the carton and packing material, even if the amplifier is undamaged. Should
you ever need to ship the amplifier, always use the original packing.

1. Carry/protection handle
Both handles can be used to carry the amplifier; they also act as protection for the front panel. In
permanent installations, or where rack front covers are too shallow they may be removed by unscrewing
the retaining bolts behind the front panel.
2. Input level attenuators
These controls are used to alter the signal level entering the amplifier. They are calibrated in dB to assist
the setup of active loudspeaker systems, or to cut down unwanted noise from the input signal. (See page
15 )
3. Over temperature protect indicator
This indicator illuminates if the amplifier is going to operate above its maximum operating temperature
(90°
°
C). The indicator first comes on as a warning to either turn down the input level or check the
cooling arrangements. Beyond the maximum temperature the amplifier will mute the input signal. Once
the cooling fans have brought the output heat sinks back to normal operating temperature the input
signal is un-muted.
