Wireless: FSII IPT (19) Fans & Filters
IP Transceiver fans and filters
The IPT operating temperature is 0 to 45°C in shaded conditions.
Each transceiver contains two fans which activate when the IPT internal temperature reaches 55°C. If the internal temperature reaches 60°C, LED 1 will flash red at 2 Hz.
You should periodically check that the fans function correctly, and if necessary replace them.
If a fan fails, LED 1 flashes red at 4 Hz.
Each transceiver contains two internal filters and one external filter to protect the device from dust and other atmospheric debris.
You should periodically clean the filters with warm water and let them dry. Replace them if they are damaged.
Clear-Com recommends that you clean the internal filters every 1 to 2 months, and that you clean the external filter every 18 to 24 months.
