Recommended separation distances between
portable and mobile RF communications equipment and the 1929LM Touchmonitor for Healthcare
The 1929LM Touchmonitor for Healthcare Applications is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
1929LM Touchmonitor for Healthcare Applications can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications (equipment) and
the 1929LM Touchmonitor for Healthcare Applications as recommended below according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distanced in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where
P
is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
