SECURITY CODING

1.

2.
The length of the base security code is 16 bytes, i.e. 128 bits.
3.
The total numbers of possible discrete digital codes are 2
to about 3.4 x 1038 different combinations.
4.
Each handset or base unit has a unique security code.
5.
Generation of the security code is by employing a sequential fixed
approach. During manufacturing, the code will be generated and
programmed into the EEPROM of the unit.

SELECTED CHANNEL

The unit may pre-scan available channels and store the detected power levels in
memory to facilitate fast selection of a channel when access is required. Since
some amount of time is required for a complete scan, the stored power level for
a selected channel may have "aged' since the measurement was taken. The unit
is therefore required to re-monitor the selected channel immediately prior to
transmission.
