4-14 Operation with a Full Function Handset
4.4.9 Setting the Transmission Power Output
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.
4.4.10 Desensitized Reception (Local Mode)
You can set the RAY215 to reduce the receiving sensitivity in high traffic
areas to decrease unwanted reception. This is also known as local mode.
To select this mode, press the FUNC key followed by the 7/D/L key. While
the desensitize function (local mode) is active, the DESENS indicator
appears in the LCD display. To return to full receiver sensitivity (distant
mode), again press the FUNC 7/D/L key combination.
4.4.11 LCD Backlight Function
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 each handset individually.
When selecting the DIM OFF setting or pressing any key while in DIM
OFF mode, the display is lit at the DIM LOW setting for 5 seconds and
then turned off. This is so you can view the display in low light
conditions.
4.4.12 Intercom Mode
Intercom mode enables conversation between a fist microphone connected
to the port on the front of the base station and a Full Function Handset
connected to the port on the rear of the base station.
