USING THE TOUCH POS 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. The installation should be such that there is at least
25mm air clearance around any top or side ventilation holes. The installation
must also be such that there is a free flow of air around the unit at ALL times.
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)
UPS Battery (option)
General care:
The UPS battery is consumables beyond product warranty. Please
note the following to preserve its serviceability as long as possible. When the
equipment is to be powered off for more than few days, please disconnect the
battery from the system and reconnect it and turn on the system to recharge the
battery for 1 ~ 2 hours every 3 months if the temperature is lower than 30°C.
Recharge for 1 ~ 2 hours every month if the temperature exceeds 30°C.
When an UPS battery is installed in this equipment, the environment
should keep below 30°C to protect the life of the battery. 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 power failure and will be automatically
recharged when system turned on with AC power presence. However, if the
AC power outage is known to last for more than few minutes (3 ~ 8 min.
depending on loading), it is advisable to turn off the system instead of using
the battery up while repeatedly using it up or improper maintenance
reduces the battery life dramatically. Please be particularly reminded to
disconnect the UPS battery if the system is to be left OFF for more than 7
days to prevent possible damage. Please be alerted that a study on brand new
well-charged battery indicates that leaving a battery connected without system
power on for recharging for 10 days or more or even storing the battery
unconnected for more than 9 months could degrade the battery capability. A
