2.3.2 Programming By Computer
Programming a radio from a computer is not covered in this manual. Contact BK Radio for the
programming cable, software, and manual required.
2.3.3 Tone Code Guard Values
The tone Code Guard system may be set for any frequency in the range of 67 to 255.9 Hz. However,
since most systems adhere to the Electronic Industry Association (EIA) standards, tones should be
selected from the following EIA list. In order to insure optimum performance, tone selection for use on
the same radio frequency (RF) channel or adjacent channels in the same coverage area should be
made from one of the Groups A, B, or C to the maximum degree possible. BENDIX/KING
guarantees optimum receiver performance only if tone frequencies below 220 Hz are chosen.

The assignments in a given area shall be made from within one of the Groups: A, B, or C.
2.3.4 Digital Code Guard Values
Codes for the Digital Code Guard system may be chosen from the following list. This can be done
during the code programming of the system. Usually systems using direct unit to unit transmission
(systems without mobile relays, repeaters, remote control, etc) may use codes from the table.
Systems with relays etc. may use code variations for system control and operational efficiency. The
system operator or engineer should be consulted regarding the operational requirement on such
systems.
