Scan Modes

Scanning is a Dealer programmable feature that allows you to monitor a number of channels. Your Dealer will help you define a channel "scan list" to be programmed into a scan channel (any channel, 1- 4 on model SP-130) or (any channel, 1-16 on model SP-140). Once that channel location is selected, scan is initiated.

Normal Channel Scan

Once the scan list is programmed you can initiate scan. Simply move the channel selector knob to the scan channel position and the radio will start to scan. The top panel LED can be programmed to flash green as the radio is scanning.

If a conversation is detected on any of the channels in the scan list, the radio will stop on that channel and you will be able to hear the conversation. If programmed for normal scan TX you will be able to transmit on that active channel during the pro- grammable scan delay time. The scan delay time is the amount of time the radio will stay on that channel once activity has ceased (Dealer programmable, 4-7 seconds is typical). The radio will resume scanning once the scan delay time has expired. Scanning will continue until the channel is changed.

Priority Channel Scan

A single channel may be programmed as the "Priority" channel. The radio will constantly monitor this channel while scanning and when the radio has stopped on an active channel. If a call is detected on the "Priority" channel, the radio will automatically move to, and remain on, the "Priority" channel for as long as the priority conversation takes place. "Priority" channel activity takes precedence over all other conversations.

NOTE: "Priority" channel scan and "look back" require that the radio leave the active channel for a fraction of a second (at regular intervals) to check the priority channel for a message. Depending upon how the radio is programmed (scan speed, etc.) this may or may not be noticeable as "breaks" on the active channel for that ssame fraction of a second.
