1 Safety and Environment

1.1 Operate the equipment with the supplied 12 VDC, 800 mA AC adapter only. Check that the
AC voltage stated on the AC adapter is the same as that available in your country. Using the
transmitter with a different AC adapter voids the warranty.
1.2 Never try to open the equipment's case. Refer servicing to qualified service personnel only.
1.3 Never place the equipment near heat sources such as radiators or electric heaters or expose
it to direct sunlight, excessive dust, humidity, rain, temperatures below freezing, or impacts.
Never use petroleum-based cleaners or paint thinners to clean the equipment.
1.4
If you do not use your equipment for an extended period of time (e.g., when traveling), dis-
1.5 connect the AC adapter from the AC outlet.
Also refer to section 4.1 Important Notes.
1.6
When scrapping the equipment, separate the case, circuit boards, and cables, and dispose
1.7 of all components in accordance with local waste disposal rules.
