• If the radio has stopped on a channel, and the operator wa nts 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 R AY210 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 trans mitter is inhibite d
in the All Sca n 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 sett ing (1 watt), p ress 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 sett ing 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 b y the FCC to be a utomat ically s et to tra nsmi t
on low power (Refer to Table 3-2 on pages 23 and 24). The operator may
override this automatic setting on some of these channels. To override the
automatic low power setting on authorized channels, press the [FUNC] key then
[1/25] key and hold.
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 sca n
(monitor) priority channel 16, a user selected channel, and selected weather
channel (monitor weather alert warnin gs). 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.
