Version: 1.01 USA Function Reference (FUNC) 3416 SCANThis is a scan function that automatically change channeland check a signal. The channel scan starts from thecurrent channel to next higher channel. This function isavailable when channels are stored and the range offrequency is specified.TKR-750/850/751/851 monitors a presence of availablesignal in each channel and stop scanning at the channelhaving a signal to receive.You can assign the [Scan On/Off] function on the PF keyand switch the scan function On/Off by pressing the key.(Refer to 15 Key Assignment.)You are also able to assign the [Scan On] function or the[Scan Off] function to an auxiliary input port in order toactivate the Scan operation by the external device. (Referto 20 Function Port.)You can configure the following functions relating to thescan function by KPG-91D.PriorityPriority ChannelLook Back Time ALook Back Time BRevert ChannelDropout Delay TimeDwell TimeOff-hook Scan16.1 Priority ScanThis is a monitoring function for priority channel duringreceiving at normal channel. When a signal appear on thepriority channel, a channel is changed to the prioritychannel even if TKR-750/850/751/851 is receiving asignal on the normal channel. The scan is started fromthe priority channel. You are able to configure theconditions for specifying the priority channel. (Refer to16.2 Priority Channel.)• FixedThe channel configured as the priority channel byFPU is preferentially scanned.• SelectedThe current channel selected by channel Up/Downkey is configured as the priority channel andpreferentially scanned.TKR-750/850/751/851 scans channels in numerical order(Normal Scan) when the priority scan function is notconfigured. (Refer to 4.12 Scan Add.)! Configuration of KPG-91D" Configuring the Priority conditions (Refer to FPRG6.6.1 Priority.)16.2 Priority ChannelThe Priority Channel is a channel to be scannedperiodically when TKR-750/850/751/851 performs thescan operation.You can configure one of the channels 1 to 16 as thepriority channel.The priority channel and other channels are displayed inthe following way. (Refer to Table 1-7 Example of LEDdisplay.)X.X When the selected channel is the priority channel(right side dot of left segment is on)XX. When the selected channel is the channel to bescanned (right side dot of right segment is on)XX When the selected channel is not the channel tobe scanned (No dot)! Configuration of KPG-91D" Configuring the Priority Channel (Refer to FPRG6.6.2 Priority Channel.)Note:# You cannot configure a Priority Channel when the priority scancondition is configured Off or Selected by FPU.# A channel does not have a receiving frequency configurationcannot be assigned to the priority channel.# It is possible to assign a priority channel to a repeat Channel.(Refer to 4.8 Operation Mode.) Although TKR-750/850/751/851transmits a receiving signal when it receives a call on the PriorityChannel, it changes channel to revert channel and transmits onwhen the PTT higher priority than the repeat PTT is activated onthe revert channel. (Refer to 16.5 Revert Channel.)16.3 Look Back Time AThe Look Back Time A is a period from the time whenTKR-750/850/751/851 pauses scanning on a normalchannel to the time when it resumes priority scan whenthere is no signal to receive on the Priority Channelduring the Priority Scan.
