Supplied: Antenna (Receive Only), SMPS Type AC Adapter, Fuji-AA type NI-MH Rechargeable

Battery (6 PCS, 1.2 V 2,700 mAh), Manual, Coaxial Cable, Earphone, Carrying Case, Carrying

Belt, RS-232C Cable, Adapter(N-BNC), Software for PC Application

The included AK2640 software and interface cable allows full control of the 2640

via a PC through the RS232C interface. The software allows the saving, recalling

and analyzing of current and saved waveforms. The 2640 can save up to 100

waveforms and states in to it’s internal memory.
