Chapter 4: Operating the Radio 37 4.13 Using the Scan Modes The RAY101 is equipped with three types of scan options: All Scan, Saved (Memory) Scan and Priority Scan. If there are no channels in memory, the default is All Scan. This function automatically searches for transmissions on the channel set being scanned. If a TX signal is received, the scan stops on the receiving channel as long as it is present and the SCAN indicator flashes. If the signal is lost for five seconds, the radio resumes scanning.
Ray101 Handheld VHF Radio In All Scan mode, all channels in the channel set are scanned in sequence, assuming no channels have been stored in memory. After the last channel number has been scanned, the cycle repeats. All Scan is demonstrated in the figure to the left. Note: Whenever Weather Alert is activated, the WX Alert channel is also monitored during All Scan. If the WX Alert tone is detected, the scan is halted to broadcast the Weather Alert message.
Chapter 4: Operating the Radio 39 Priority All Scan Press and hold the SCAN/SAVE key while All Scan is active to initiate Priority Scan. . During Priority Scan, the PSCAN indicator appears on the LCD. Priority Scan searches for activity on all channels but alternates scanning the Priority Channel 16 after each channel. Priority Scan is demonstrated in the figure to the left. Note: Whenever Weather Alert is activated, the WX Alert channel is also monitored during Priority All Scan.
Ray101 Handheld VHF Radio Priority Saved Scan Press and hold the SCAN/SAVE key while Saved Scan is active to initiate Priority Saved Scan. The PSCAN and SAVED indicators appear on the LCD. Priority Saved Scan is much like Priority Scan except that the radio alternates searching for activity on the Priority Channel 16 and the channels stored in memory. Priority Saved Scan is demonstrated in the figure to the left.
Chapter 4: Operating the Radio 41 4.14 Adding Channels to Memory The Ray101 can store any channel except the weather channels. The stored channels are the ones scanned in the Saved (Memory) Scan mode. ➤ To add channels to memory: 1. During normal operation mode, use the UP/DOWN key to select the desired channel for programming. 2. Press and hold the SCAN/SAVE key for 3 seconds. D6704-1 The SAVED icon appears to indicate the current channel has been saved in memory.
Ray101 Handheld VHF Radio 4.15 Using the Monitor Modes The Watch Modes monitor the programmed Priority Channel and other userselected channel(s). The watch is halted when activity is detected on a monitored channel. The Ray101 is equipped with 2 types of monitor operations: Dual Watch and Tri Watch. Dual Watch Press and release the DW/TRI key to activate the Dual Watch mode. The DUAL indicator appears on the LCD. Dual Watch monitors the current working channel and Channel 16 in cycle.
Chapter 4: Operating the Radio 43 Tri Watch Press and hold the DW/TRI key for 3 seconds to activate Tri Watch mode. The TRI indicator appears on the LCD. Tri Watch monitors in cycle Channel 16, the current working channel and the channel you have set as the Secondary Priority Channel. Tri Watch is demonstrated in the figure to the left; the sample working channel is CH 72. Note: Whenever Weather Alert is activated, the WX Alert channel is also monitored during Tri Watch.
Ray101 Handheld VHF Radio 4.16 USER Channel Mode Press and hold the HI/LO / USER key while in normal operation mode to enter User Mode. The USER and SAVED indicators appear. USER Channel Mode displays only the channels that you have saved to memory, which enables you to easily use your favorite channels while bypassing unwanted or seldom-used channels during a scan. Note: The procedure for saving a channel to memory is outlined in Section 4.14, Adding Channels to Memory.
Chapter 4: Operating the Radio 45 4.17 Resetting Factory Defaults You can reset many radio settings back to their factory defaults: • • • • Erase any channels stored in memory Return to US channels, if another mode is selected Turn OFF the Weather Alert setting, if active Return power settings to their original state ➤ To perform the reset: 1.
