The transmission output can be set at either 1W or 25W. When the power
supply is switched on, the output is 25W. Pressing the FUNC key followed
by the 9/1/25 key alternates the transmission between 25W and 1W. When
1W is selected, the 1W indicator is displayed on the LCD. When 25W is
selected the 1W indicator disappears.
This key is also used to override the programmed 1W setting in US mode
on Channels 13 and 67. To override, first select the channel. Press and hold
PTT and then the 9/1/25 key. While these keys are pressed, the power
output is 25W instead of 1W on these two channels.

You can set the RAY230/E to reduce the receiving sensitivity in high traffic
areas to decrease unwanted reception. This is also known as local mode.

indicator appears in the LCD display. To return to full receiver sensitivity
(distant mode), again press the FUNC 7/D/L key combination.

LCD backlight brightness can be set at four different levels. Press the
FUNC/DIM key two times to enter Dimmer mode. Each successive click of
the FUNC/DIM key alternates the brightness from Off, to Low, to Medium,
to High, then back to Off. As the backlight setting is changed, the dot
matrix indicator displays the following messages: DIM OFF for the Off
setting, DIM LOW for Low, DIM MID for Medium, and DIM HI for High.
When the ENT or CLR keys are pressed or when no other key operation is
made for 5 seconds, the current state is accepted and stored in memory,
and the backlight setting operation is complete. The next time the power
supply is switched on, the state of the backlight is recalled and is applied
to all handsets.
