7.4.5.5 Muting Outputs
The SPEAKER, SCENE, LEVEL, DELAY/PHASE and
ADMIN keys serve the second purpose of muting
outputs. The label above each key tells you its
mute function. To mute outputs, press and hold
the MUTE/HOLD key and press the key of the
output you wish to mute (key A to D for Output A to
Output D). The Lim/Mute LED in the given output’s
LED chain lights up red to indicate the output is
muted. Follow the same procedure to enable the
output.
7.5 Firmware
The FIRNET controller ships with the current fi rm-
ware. LIPAN software lets you update the device
with future fi rmware versions. See chapter 4 LIPAN
PC Software, to learn more about fi rmware updates.
This is to certify that
HK AUDIO
®
FIRNET
complies with the provisions of the Directive of
the Council of the European Communities on
the approximation of the laws of the Member
States relating to electromagnetic compatibility
according to EMC Directive 89/336/EEC inclu-
ding amendment 93/68/EEC and the low voltage
Directive 73/23/EEC including amendment 93/68/
EEC. This declaration of conformity of the Euro-
pean Communities is the result of an examination
carried out by the Quality Assurance Department
of STAMER GmbH in accordance with European
Standards EN 50081-1, EN 50082-1and EN 60065
for low voltage.
