This device has been designed to operate with the antennas listed below.
UHF Antennas not included in this list, or that have a gain greater than 5dBi, are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
The antennas that can be used (country dependent) with the 460 MHz radio are 0dBi and
5dBi whip antennas.
The antenna that can be used with the GSM radio is the 0dBi whip antenna.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropic ally radiated power is not more than that permitted
for successful communication.
Rechargeable Lithium-ion batteries
These receivers use a rechargeable Lithium-ion battery.
WARNING
- Do not damages the rechargeable Lithium-ion battery. A damaged
battery can cause an explosion or fire, and can result in personal
injury
and /or property damage. To prevent injury or damage:
- Do not use or charge the battery if it appears to be damaged. Signs
of
damage include, but are not limited to, discoloration, warping,
