Part 13
replace the used up UPS battery at power off as soon as possible.
Emergency treatment:
The battery is constructed maintenance free and leakproof. Its storage
space in HT system also provides very good protection as long as the ambient
temperature remains below 30°C and the ventilation of the HT system remains
free. However, should any accident happen and the sulfuric acid from the
battery spills on skin or clothing, wash immediately with water. If the acid
comes in contact with eyes, rinse eyes with large amount of clean water and
see a doctor immediately. A larger external battery may be connected to give
an extended operation. Please check your dealer about this capability when
required.
WARNING:
If there are any signs of over charging or leakage of electrolyte
please contact your dealer immediately
VGA Display Port
The VGA port in the HT terminal can be connected to the 10.4” rear
mount optional 2nd monitor LM-2010 with appropriate power arrangement.
The video memory of this port shares from the system memory. The

application.
Serial Port – COM1
For the HT system with the UPS function, a COM1 terminator will
also be supplied. Please always occupy COM1 serial port by a suitable serial
device or this terminator. If this port is left vacant or connected with something
like a mouse, the power switch management and the cash drawer control may
fail to work correctly. An RS232 MODEM is not applicable to this port. It is
recommended to use COM2.

in green, the onboard LAN chip is linked. When it flashes in yellow with
steady green light, data transmission in LAN is in process. The LED at left
indicates Power/StandBy status. When it lights up in orange, it means that the
external AC power is standing by with the system powered off. It turns into
blue when the system is powered up. When the UPS battery is installed, this
LED further indicates the status of system working on battery power by
flashing in blue. The blue light will flash rather fast when the UPS battery
approaches a fully discharged condition to remind the operator that power will
soon finish. In few seconds, the whole system will soon be automatically
turned off and the LED will be OFF. In case the AC power resumes during the
