•If the radio has stopped on a channel, and the operator wants to transmit on that channel, pressing the PTT switch will cancel the scan function and the RAY210 will remain on that channel.
•If the radio stops on a channel during the scan mode due to a received signal, the operator can cancel the scan function and the RAY210 will remain on that channel. If no signal was present when the All Scan is deactivated, the radio will revert to the channel in use prior to the selection of All Scan.
When the radio is in the All Scan mode, the keyboard is inoperative except for the following keys: [SC], [DIM], [VOLT], and [16]. The transmitter is inhibited in the All Scan mode.
NOTE: During scanning operations, a VHF radio will sometimes stop on a particular channel for no obvious reason. This can be caused by electrical noise and interference that may be common to a particular port or harbour area.
7) [1/25] (high / low power) key:
This secondary function is used to toggle the transmit power setting between 25 watts and 1 watt. To set the transmitter to low power setting (1 watt), press the [FUNC] key, then [1/25]. 1W will then be displayed on the LCD and your RAY210 will apply approximately 1 watt of power to the antenna during transmit operation. When 1W is not displayed on the LCD, the radio is set to provide 25 watts of power to the antenna. The low power setting is provided for situations where the parties communicating are close to each other. This reduces radio channel congestion in distant areas, allowing more individuals to use the same channel at a given time.
Some VHF channels are required by the FCC to be automatically set to transmit on low power (Refer to Table
8) [DWX] (Dual Watch Plus Weather) Key:
This secondary function key activates Dual Watch plus Weather Mode and illuminates the DWX symbol on the LCD. In this mode, the RAY210 will scan (monitor) priority channel 16, a user selected channel, and selected weather channel (monitor weather alert warnings). To operate this mode, first select a working channel, then select a weather channel by pressing the [WX] key and set to desired channel. Pressing [FUNC] key and then the [DWX] key will activate the DWX mode. Pressing the [FUNC] and then the [DWX] key again cancels the DWX mode.
