4-12 Operation with Full Function Handset
4.6.4 Setting the Frequency Mode
The RAY215E can transmit and receive on all available International
marine VHF radiotelephone channels. With a software upgrade, the
RAY215E can also communicate on the US channel set.
Indicators displayed in the LCD identify the active frequency group: US
for the US frequency group, or INT for the International group.
Pressing the FUNC key followed by the INT key alternates the frequency
groups from US mode to International mode then back to US mode. When
the radio is powered on, it starts on Channel 16 in the frequency group
last selected.
Note: Some countries require special licensing to activate the US
channels.
When the frequency group is changed, the channel number remains the
same as was selected in the previous group, as long as that number is
present in the new group. If a channel number is absent in the destination
group, the new channel will be the previous number plus 1. When returning
to the previous frequency group, the channel returns to its original number
if the channel has not been changed. If the channel has been changed, that
number is retained when the frequency group is changed.
Example 1
CH15 INT
⇒
CH15 US
⇒
CH15 INT
When shifting the frequency group, the channel remains the same because
the corresponding channel number exists in the new frequency group.
Example 2
CH2 INT
⇒
CH3 US
⇒
CH3 INT
No corresponding channel exists in the new frequency group, so the
channel is incremented by 1.
Example 3
CH2 INT
⇒
CH3 US, then changed to CH5
⇒
CH5 INT
⇒
CH5 US
However, if the channel is changed in the new frequency group, this new
number is retained when the frequency group is changed.
