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  /4-shifted Differential Quaternary Phase Shift Keying ( /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 modifications are expressly approved by PowerTrunk. In this case, the user could
lose the authority to operate with this equipment.

RF Exposure and SAR Requirements
Your HTT-500 terminal and the accessories approved by PowerTrunk are designed and
manufactured not to exceed the limits of exposure to radiofrequency energy, in compliance
with the international regulations for this purpose.
These regulations, which are result of periodical scientific trials by independent organisations,
include a considerable safety margin, designed to guarantee the safety of all staff, regardless
of their age or state of health.
The following labels will be placed in conspicuous view on the HTT-500:
