Posiflex FT-7715 - Manual (Page 13)

Part 13
USING THE TOUCH TERMINAL
APPLICATION ENVIRONMENT
It is very important that you check the following operational
guidelines:
Ventilation
This terminal must NOT be operated in an environment with
restricted ventilation. There must be at least 25 mm air clearance around any
top or side ventilation holes with a free flow of air around the unit at ALL time
for the installation.
Operating Environment
The equipment must not be operated or stored in extremes of both
temperature and humidity/moisture. (Operating range 5°C to 40°C and up to
80% humidity – non condensing, max. wet bulb 26°C)
UPS Battery (option)
General care:
The UPS battery is consumable beyond product warranty. Please
definitely observe the alerts in the beginning of this manual. If the equipment
is to be powered off for more than few days, please always disconnect the
battery from the system. Reconnect it and turn on the system to recharge the
battery for 1 ~ 2 hours every 3 months for temperature lower than 30°C.
Recharge for 1 ~ 2 hours every month for temperature over 30°C. Temperature
above 40°C must be strictly avoided as it could cause termination of battery
life and unexpected result even if the battery is not in work. The UPS battery
can support basically the data preservation and smooth running of the system
during intermittent or few minutes (within 30 min. depending on loading and
battery condition) power failure.
Battery replacement:
In the preloaded OS for a FT system, there is a built-in utility Power
Manager that will interface the UPS battery monitor status with user. When
battery monitor disables the battery charging as designed while the UPS
function of the system is originally enabled, in other words the UPS battery is
found out of order if actually installed, there will be a popup message as the
picture at right asking the user to agree disabling the
UPS function. The system will operate under
deactivated UPS function no matter agreed or not.
However, the monitoring goes on and the popup
message will come back on next system power up boot if not agreed. In any
case, please replace the used up UPS battery at power off if the battery is well
