Troubleshooting 8-19
Electromagnetic Interference
Operating the ML910 Rugged Notebook in too close proximity to some two-way radios
receiving certain frequencies (channels) can cause reduced receiver sensitivity and/or
interference with communications. This would occur on discrete radio frequencies in the
VHF, UHF Range 2, and 800 MHz Land Mobile Radio bands. In the case of Carrier
Squelch voice radios, bursts of noise may be heard in the radio's speaker when the
radio unsquelches.
Radios operating on the following frequencies or in these frequency ranges may be
susceptible to this interference: 152.0075 MHz, 166.25 MHz, 169-172 MHz, 458.18125
MHz, 472.0125 MHz, 472.01875 MHz, 480.00625 MHz, 480.0125 MHz, 498.75– 512
MHz, 850–857.5 MHz, 859.0625 MHz, 859.0875 MHz, 859.9875 MHz, 860.0125 MHz,
and 862.5–866.5MHz.
Note:
Almost all electronic equipment, including personal and notebook computers,
unintentionally produces low levels of radio frequency (RF) emissions. The maximum
allowed level of these emissions is set by the US Federal Communications Commission
(FCC), Industry Canada (IC) and other regulatory agencies elsewhere. The ML910
Rugged Notebook complies with these regulations, yet highly sensitive two-way radios
may be affected when operated too close to the notebook and similar electronic
equipment.
Recommendation: Maintain additional distance between the ML910 notebook and
the interfered portable two-way radio or the vehicle-mounted antenna of a mobile
two-way radio that uses any of the affected frequencies or range of frequencies.
