Getting started | RS90 Operating Manual
Setting transmission power
The RS90 has two transmission power settings:
High 25 W
Low 1 W
To change the power setting:
Press and hold [H/L] until the Hi or Lo icon on the display changes.
¼ Notes
• Channel 16 always remains in high transmission power.
• Some channels allow only low-power transmissions. If you try to
change to high power, the RS90 will sound an error beep.
• Some channels allow only low power transmissions initially, but can
be forced to high power by holding down [H/L] and PTT at the same
time.
• See “Appendix 11 - US and ROW VHF marine channel charts” on
page 114 for a list of channel data.
PTT Key
The Push to Talk (PTT) key activates the microphone and transmits
your voice over the selected channel.
¼ Notes
• Pressing PTT while a menu is displayed will exit the menu without
making any selection.
• DSC transmission has higher priority than PTT voice transmission.
• During PTT transmission, the radio cannot receive a DSC call.
• If PTT gets stuck or accidentally held in the talk position, a built-in
timer sounds an error beep and shuts down the transmission after 5
minutes.
