USING THE HT SYSTEM
BEFORE POWER ON – A Check List
It is very important that you check the following operational points:
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 times for the installation.
Operating Environment
The equipment must not site in direct sunshine, near a heater or in a damp and must be free from contaminants like dust, smoke or fume.
The equipment must not be operated or stored in extremes of both temperature and humidity/moisture.
(Operating range 0°C to + 35°C and up to 80% relative humidity – non condensing max. wet bulb 26°C)
Power Supply
The operating voltage of the power supply should be checked to confirm that it is set within the range of the local power supply. The power cable, the power outlet and any power fusing arrangements must conform to local safety regulations.
UPS Battery (option)
General care:
The UPS battery is consumable beyond product warranty. Please definitely observe the alerts in 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 (3 ~ 20 min. depending on loading and battery condition) power failure.
Battery replacement:
