5 Operation
5.1 Apply Power
Once power is applied to the LHDMI44 it will go through a Power Up routine lasting a
minute or two. The display LEDs will cycle blue in a Right to Left direction.
When this routine is completed the unit will reconnect the most recent state (Source –
Zone selection or standby) The display LEDs will glow green indicating the switched
sources and zones.
The left hand four LEDs indicate input sources 1 to 4, left to right.
The right hand four LEDs indicate output zones 1 o 4 left to right.
Standby will be indicated by the right hand LED only, pulsing green/ blue.
5.2 Calibration
The system should be calibrated on first use, after any new devices (source or
zone equipment) are added, port allocations changed or after power has been
interrupted and reapplied. Failure to correctly calibrate a system may lead to
interruption to audio and video at zones when other zones are switched to a
source that is already in use.
The system may be calibrated under RS232 control or manually by following
these steps.
1. Turn on all sources and zone equipment (receiver or TV). Ensure that zone
equipment (TV’s etc) are set to the correct HDMI input.
2. Press and hold operated the left hand press button switch on the front panel
for 3 seconds to commence calibration.
