PL1(plan1): If the last three digits of ALL the frequencies in use end in one of the following three digits (125, 375, 625, or 875), use PL1(plan1).
PL2 (plan 2): 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 2.
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: • You can assign a Fleet Map to TYPE 1 or Hybrid systems scanned in Control Channel Only mode by going into the Trunk Programming mode. You can also pro- gram IDs, set a delay, 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.
•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 systems, that you do have to set the proper system type (800 MHz of Type 1 or Type 2) and you do have to program the Control Channel frequency into memory and identify the frequency as trunked in the Trunk Programming mode.
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.
1.Press and hold TRUNK for 1.5 seconds and select the bank you want to change.
2.Use the 
or 
key to select 
(Motorola TYPE2 800MHz), 
(Motorola Type2
VHF) or 
(Motorola Type2 UHF), then press E.
3.Use the 
or 
key to select 
, then press E.
4.Use the 
or 
key to select 
or 
, then press E.
Note: Set the SQL control so that you hear a hissing, and the scanner will remain on the voice channel (even when a disconnect tone is transmitted or there is no signal at all).
