SIGNAL TYPE AND
NAME DESCRIPTION
Inputs: <
AM_

Tunes the AM or weather station up (+) or down
(-), for as long as the input is high.
Users can tune to stations by pressing the up (
k
)
or down (

) buttons on the AM/WX Tuner or the
FM Tuner when the unit is in TUNE mode; or by
using remote buttons defined on a touchpanel or
other interface.
The /- function will continue until the input
goes low (the local or remote tune button is
released).
The tuner will jump in 10 kHz steps if in US mode;
or in 9 kHz steps if in European mode. The step
rate is selected via the <
AM_US/Europe
> input.
High/1 = Station up or down (tune button pressed);
Low/0 = Stop station changing (tune button
released)
Input: <
AM_US/Europe
>
Selects the AM frequency step rate. When low, the
frequency is set to US steps (10 kHz). When high,
the frequency is set to European steps
(9 kHz).
The tuner stores the frequency selection in the
EEPROM. On power-up, it restores this value.
High/1 = European mode; Low/0 = US mode

button on the FM Tuner when the unit is in Preset
mode; or from remote buttons defined on a
touchpanel or other interface. (The AM/WX Tuner
does not provide a local Save button.)

not supported in the weather band.
Users can search for AM stations by pressing
remote buttons defined on a touchpanel or other
interface. (Neither the AM/WX Tuner nor the FM
Tuner provide AM search buttons.)
The Search function will continue until
1) the remote search button is released; or

High/1 = Search up or down (remote search button
pressed, AM band only); Low/0 = Stop search
(remote search button released)
