ready after a normal power off. For LAN wakeup, an operating caller system
connected through LAN to the system is required. It also requires a qualified
networking technician to check the LAN chip ID of the HT system for the
caller system to wake it up.
When the HT system is turned off after a successful boot up, the
preset automatic power on functions will keep monitoring for the preset
conditions and turn on the system when the preset conditions are met.
Please note that if the HT system is improperly turned off before a
complete boot up procedure, the above preset power on control functions will
be disabled until next turning off after a complete boot up.
Emergency Power Off
In case of serious system halt due to any reason, the system could fail
to be powered off through normal means. Press and hold the Power ON/OFF
Switch for Emergency Power Off. Release the switch after the system powered
off. It will take about 4 seconds if no UPS function module installed and it
takes about 10 seconds if the option installed. If there appears to give a special
coded beep tone in the pattern “short, long, short, long, short” prior to the
system power off in this process, please remove the AC power and wait for
few minutes to allow the hardware registers to reset (If there is no such beep,
AC removal is not required). Then you may restart the system and take
remedial action against the precious failure.
MAIN LCD TOUCH MONITOR
Mechanical Adjustments
The 12.1” LCD color display is integrated on display platform to give
the operator the clearest view. The display may be adjusted to have the
inclined angle from 42.5° to 77.5° and rotated from straight forward to 16° to
the left.
Display Controls
On lower left edge of back of the LCD panel
there is a plastic wheel knob as circled in the picture at
right. Turning this knob up or down changes the
brightness of screen display accordingly.
Display Utility Driver
The end user of the HT terminals is not supposed to install the utility
drivers personally. If an optional preloaded OS is ordered, the required driver
will be already installed in the preloaded OS. However, the driver will always
be available over our web site: http://www.posiflex.com
