This device may contain functions that are not operational in U.S Territories except as noted in the
certification filing. The grant has extended frequencies as noted in the certification filing and Section 2.927(b)
applies to this authorization.
The equipment complies with 47 CFR Part 90.203 (e), in that the operator can not directly program the
transmit frequencies using the normal accessible external controls”
Access scheme is Time division multiple access (TDMA) with 4 physical channels per RF channel.
RF Channel Bandwidth (Channel spacing) is 25 KHz. So, the equipment meets a spectrum efficiency of one
voice channel per 6.25 KHz of channel bandwidth.
Modulation scheme is π/4-shifted Differential Quaternary Phase Shift Keying (π/4-DQPSK) with 18Ksym/sec.
modulation rate, equivalent to 36Kbits/sec. So, the equipment meets a data rate on each physical channel of
9000bits/sec. per 6.25 KHz of channel bandwidth.
Unapproved modifications or changes to this equipment may cause harmful interference unless the
