SOUND PORTS
The audio port on Jiva system with slim base supports a Microphone in and a stereo line out jacks. There is a single channel internal audio amplifier in the output port to drive the 2 slim type speakers installed in the I/O area inside cable cover as in the picture below with 1 W audio power (For TP/LT- 5615/5715/5815 this item is an option).
Should the application demand for
higher audio power, please first ask your dealer to disable the internal audio
amplifier and connect a pair of speakers with booster or amplifier to
this port. Please note that this modification is a highly technical operation and should not be handled by any person else. Please also note that the number and types of I/O ports shown in picture above may evolve with time without notice.
FAN CONTROL
In the preloaded OS for Jiva system, there is an embedded function that keeps monitoring the interior temperature and the fan revolution rate and regulating each required fan power to gain maximum ventilation effect with lowest possible noise. The end user may select “Start”, “Programs”, “Posiflex Tools”, “Posiflex Fan Control Tools”, “Enable Posiflex Fan Controller” in sequence to enable this function. This tool will remain enabled even after system turning off/on until being disabled.
On occasion of system unexpected shutdown, please review the ventilation condition and environment temperature of the system. Check if the fan is stuck by contaminants such as dry grease or threads. Try to correct the situation when the system is off and cooled down. You may power up the system again after the system cooled down and trouble cause removed. However, if the situation repeats again and again, please consult your dealer for possibly fan replacement on worn out.
