Battery Recharging 
Plug-in Supplies 
A mains plug-in supply must be designed to ensure that voltage spikes, 
lightening and other power fluctuations cannot damage the Boomer II. 
Transient voltage protection zener diodes or other spike arrestor 
circuits may be added to keep the inputs within the power requirements 
mentioned previously. These should have a value of 20V and be placed 
on the supply side of the regulator circuit. 
Automotive Supplies 
Extra protection is required from an automotive supply to protect the 
Boomer II OEM Modem from power fluctuations when used in an 
automobile. 
The electrical transient conditions (e.g. battery jump start), may 
damage the modem if not adequately clamped and filtered. 
Environmental Considerations 
The environmental requirements of the Boomer II OEM Modem are as 
follows: 
 
 
These limits should not be exceeded in the intended application.
Operating Temperature: 
-30° to +60°C  
Storage Temperature: 
-40° to +70°C  
Relative Humidity 
0 to 
95% non-condensing
