POWER ADAPTOR
The power connector resides in the lower left corner of main connector area. Please make sure that the cable from the power adaptor is inserted into the power connector of HT system in the correct orientation as illustrated in right drawing. The manufacturer is not responsible for any damage caused by improper orientation of this connection. Please check that for straight type power plug the arrow mark on the plug is
at top side of the plug. For right angled power plug, if the arrow mark is on its end, it should be pointing up. If
the arrow mark is on one side of the right angled power
plug, it should be on the right as in the drawing. Please also check that the city power supply specification from the wall socket is within the operation range of the power adaptor.
WIRELESS LAN (OPTION)
When the wireless LAN option is ordered with the HT system, this option is already installed in the delivery inside the back cable cover with its cable connected to one of the USB port. This cable must be disconnected first if installed whenever the back cable cover is opened for any operation.
UPS BATTERY (OPTION)
When the HT system is installed
with the UPS battery, the UPS battery is in the carton at delivery. Please take it out and place it in the battery compartment at center upper part of the connection area indicated
as upper rectangle in picture at right. Connect the cable to its connector in the main connection area beside the power
connector only when the system is about to power up for operation. Always disconnect the UPS battery when the system is to be left powered off for more than few days. Please pay particular attention to the environment requirement for UPS battery in next chapter “USING THE HT SYSTEM”.
