RDS function Market model SUBARU GENUINE model
AF search Can be switched on and off. Fixed to on.
· Default: On · AF search cannot be disabled.
·
With the auto memory function, only RDS stations can
be set in the memory for the FM band.
AUTO TP search Can be switched on and off. Fixed to off.
· Default: On · Even when TI is turned on, if the station currently
tuned in is not a TP station, it is never interrupted for
traffic announcements.
Auto antenna No auto antenna control for the E type. Auto antenna control is conducted.
· Even when set to another source, if an FM station is
tuned in in the background, the auto antenna output
is turned on.
UP/DOWN key versions
The UP/DOWN key operation is set with the menu.
When pressed normally: 1 step up/down
When pressed and held in: Auto seek
· No continuous manual up/down
· No AUTO 2
PRESET SCAN No preset scan function SUBARU GENUINE model preset scan is conducted.
· Tuning switches up to the next preset channel every
10 seconds. Once all the channels have been
scanned once, preset scan does not stop but
continues in the same band.

(6) When TEL MUTE is turned on/off.
(7) When the band or the frequency is switched

CAUTION:For continued safety, replace safety critical components only
with manufacturer’s recommended parts (refer to, parts list). Indicates
safety critical components. To reduce the risk of electric shock, leakage-
current or resistance measurements shall be carried out (exposed parts
are acceptably insulated from the supply circuit) before the appliance is
returned to the customer.
DC voltages are as measured with a high impedance voltmeter. Values may
vary slightly due to variations between individual instruments or/and units.
