Measures to observe
Note 1 – The floor should be antistatic (wood, ceramic, etc.). If carpeted, the relative humidity
should be maintained at 30%.
Note 2 – The main power supply must be of residential, commercial, or medical grade.
Note 3 – If operating for an extended period, a UPS system must be provided in the event of a
power outage.
Note 4 – Mobile or portable RF communication devices should be used at greater distances than
those provided in table 3.
Table 2. electromagnetic immunity
1.5.1. recommended distance from Radio Frequency systems
It is not recommended to use RF transmitting devices near the SD32+ digital amplifier. RF
transmitting devices can cause interference with the device and impact the quality of the signals
being acquired during use.
To prevent RF interference it is recommended to maintain a minimum distance between the
SD32+ digital amplifier and the RF transmitting device being used; such as cell/mobile phones.
The following table shows recommended distances that the SD32+ digital amplifier should
remain from some common RF transmitting devices.
