Insert the Handset Cable into the Handset and into whichever Audio Jack, 

Headset or Handset, is to be used.

NOTE:  115200 is the default for CDMA.  9200 is the default for GSM. 

4.2.2 Power Supply 

The Power Adapter supplies 4.0 Volts DC and a maximum of 2.0 Amps.  It can 

be plugged into a 110 Volt or 220 Volt Mains input. 

 

If a lab power supply is used instead, it should be set for 3.8 Volts DC with a 

minimum current limit of 2.0 Amps. 

4.2.3 Interface Board 

Install the SNGL/DIFF Jumper as desired.  Refer to the details above under 

.  The OFF/ON switch can be in either position when power 

is applied, but will have to be moved to the ON position after the power is 

applied in order to activate the module.  The BOOT switch should be left in the 

HI position for normal operation of the GSM/GPRS Module.  For CDMA 
Modules, the state of this switch is not critical.
