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 times for the
installation.
Operating Environment
The equipment must not be operated or stored in extremes of both temperature
and humidity/moisture. (Operating range 0°C to 40°C and up to 80%
humidity – none condensing, max. wet bulb 26°C)
Power Supply
The operating voltage range of the power adaptor should cover the local power
supply for proper operation. The power cable, the power outlet and any power
fusing arrangements must conform to local safety regulations.
Please never do any connection / disconnection when system is still powered
on. Please always keep the external power adaptor in a free air circulation.
Automatic Power on Control
The system may also turn on according to some preset conditions such as
Modem Ring Up and Alarm Clock Wake Up or LAN Wake Up.
When the TX system is turned off after a successful boot up, the preset
automatic power on functions will keep monitoring for the preset conditions
and turn on the system when the preset conditions are met.
Please notice that if the TX system is improperly turned off before a complete
boot up procedure, the above preset power on control functions will be
disabled until next turning off after a complete boot up.
