PLAN 1
: Use Plan 1 if the last three digits of ALL the frequencies in use end in one of the
following three digits: 125, 375, 625, or 875 (example: 856.1125, 860.7375, 859.6625,
855.8875).
PLAN 2
: If the last three digits of frequencies are less than 869.0000 and end in one of
the following three digits (125, 375, 625, or 875) and if ANY other frequencies end in (000,
250, 500, or 750) use Plan 2.
PLAN 3
: If the last three digits of ALL the frequencies in use end in one of the following
three digits (000, 250, 500, or 750) use Plan 3.
PLAN 4
: If the last three digits of frequencies are less than 866.0000 and end in one of
the following three digits (000, 250, 500, or 750) and if ANY other frequencies end in (125,
375, 625, or 875) use Plan 4.
Of course you will know the Control Channel frequency itself so that will help you determine
the proper plan. If you try one plan and you receive errors (such as the scanner jumping to
channels that are obviously not part of the system), you should try an alternate Plan.
Note
: In Chain Search mode, Control Channel Trunk is activated in the Menu mode (See
page 20). You must choose one of 4 frequency plans. This plan applies only when
the scanner searches the 800 MHz range. Since a default plan is automatically
used when the scanner searches the 900 MHz range, a user does not need to
select a plan.
Note
: You can assign a Fleet Map to TYPE 1 or Hybrid systems scanned in Control
Channel Only mode by going into the Menu. You can also program IDs, set a delay,
alpha tags and all the other parameters for systems scanned in this mode. You can
then either search the system to find new IDs or you can program IDs into memory
and then scan them.
Note
: The Control Channel Only feature is an extremely powerful tool. You can use it to
determine if systems you are familiar with may have added new frequencies or you
can use it to discover new systems by simply finding active control channels (using
Search) and then programming them for Control Channel operation only.
Remember that this feature only applies to Motorola 800 and 900 MHz systems,
that you do have to set the Menu for the proper system type (800 MHz of Type 1 or
Type 2 or 900 MHz) and you do have to program the Control Channel frequency
into Memory and press and hold the
TRUNK
key to identify the frequency as
trunked.
Disconnect Tone Detect Option (End Code)
When this function is disabled, the radio looks for squelch before returning to the Control
Channel instead of waiting for the Disconnect Tone. Only in rare instances will you need to
adjust the default settings.
The condition to return to Control Channels depends on whether the signal is present or not.
