Avoid extreme temperatures
Extreme operating temperatures can affect PDM batteries and
interfere with System operation. Avoid using the PDM in temper-
atures below 40°F (5°C) or above 104°F (40°C).
Electrical interference
The PDM is designed to withstand normal radio interference and
electromagnetic fields. However, as with all wireless communica-
tion technology, certain operating conditions can interrupt
communication. For example, electric appliances such as micro-
wave ovens and electric machinery located in manufacturing
environments may cause interference. In most cases, interrup-
tions are easy to resolve (see Chapter 11, Communication
Failures).
Do not store or leave the PDM where it may be
exposed to extreme temperatures, such as inside a
car. Extreme heat or cold can cause the device to
malfunction.
