Special button combinations and functions
In addition to the ability to perform a factory reset and forcing certain output
resolutions, other button combinations are available:
These button combinations only work when the unit is switched
on and active i.e. with the STANDBY/ON LED is off. They will not
work in Standby mode, or during power-up.
5.4.1 Locking front panel buttons & IR remote control
This can be performed by pressing STANDBY/ON and FREEZE at the same time.
All front panel buttons and IR remote control commands will be disabled, with the
exception of repeating the above combination to un-lock the unit and for storing the
current locked buttons setting (thus letting you make sure the unit always starts up
with the buttons locked). The IR remote’s LOCK and STORE buttons will always be
active, giving another way to turn button/IR remote locking off.
The STANDBY/ON button will flash when the unit’s buttons are locked.
5.4.2 Restore power-on settings
This can be done (without having to turn off the unit) by pressing STANDBY/ON
and the multi-directional switch at the same time until a single beep is heard.
5.4.3 Factory Reset
If you wish to restore all operational parameters to their original condition (for
example, if saved settings prevent the unit from working with your display monitor),
hold the STANDBY/ON and the multi-directional switch in together until two beeps
are heard.
All stored settings except resolutions are lost when the unit is
reset. A Firmware update is the only way to perform a complete
factory reset (including resolution data).
