T-405TX
The T-405TX features a Timer function that enables you to start playing or recording a specified
component at a specified time.To use this function ,you need to configure a system that includes
an ONKYO amplifier A-905TX connected to the T-405TX and other components via
REMOTE CONTROL jacks.
The following button and setting modes are used to operate the Timer function.
You can use the remote controller(that comes with the ONKYO amplifier A-905TX),
as well as the front panel of the T-405TX.
Timer setting modes
WEEKDAY This mode enables you to listen to
a specified component at a designated
timer on weekdays.You canchange the
day of the week in DAY SET mode.
WEEKEND This mode enables you to listen to
a specified component at a designated
time on weekends.You can change the
day of the week in DAY SET mode.
You can define the same day of the
week as both WEEKDAY and
WEEKEND.To set two Programs for
one day,specify the same day of the
week as WEEKDAY and WEEKEND
and set the time for each program.
REC This mode enables you to record your
favorite broadcasting program(s)
starting at a designated time .You can
select from NEXT,the day of the week,
and EVERYDAY.Except for EVERYDAY,
the unit performs the timer recording
once at the designated time.
DAY SET This mode enables you to change the
day setting(definition)of WEEKDAY
or WEEKEND
ADJUST This mode enables you to set and adjust
the clock.If you have Adjusted the clock,
you do not need to set it again.
TIMER button
Use this button to select a timer mode.
The timer modewill change each time
you press this button.
PRESET( / )buttons(T-405TX),or
UP/DOWN( / )button(Remote controller)
Use there buttons to select the details
of the mode or to change values.
MEMORY button(T-405TX),or
