PRESET 1
THROUGH
PRESET 5
FUNCTION
To Designate A Preset Memory
Band Change
DESCRIPTION
These keys designate the number of the preset memory to be called and
written.
a) In case of calling a preset memory:
Calls frequency data memorized in the PRESET memory designated
by a key, and receives that frequency. In SW bands, the data for the
meter band are also called. The LCD display displays "PRESET" and
the preset-memory number.
In case of writing a preset memory:
When one of these PRESET keys is pressed while depressing the
"ENTER" key, the frequency data of the receiving frequency are
written in the designated or selected preset memory channel, and the
display displays the "PRESET" and the memory number on it.
These "PRESET" and memory number displays on the LCD disappear
when the rotary encoder is rotated and the receiving frequency is
changed, receiving band is changed or when the radio is turned off.
When one of these keys is pressed, the receiving band becomes in that
band pressed. And the receiving frequency becomes in the last channel
memorized in the system. When the same band key is pressed as the band
now receiving, the second pressing is negrected.
Shortwave Meterband Change
The shortwave receiving spectrum is divided into 12 (twelve) broadcast
bands. Each band up to 41-meter band is further divided into 104 chan-
nels, and each band up to 13-meter band is further divided into 128
channels. The 11-meter band is divided into 126 channel.
a) When the ''UP"' key is pressed while receiving a shortwave band, the
receiving band changes to the next higher band successively. When
the SW12 (11-meter) band is reached, however, the band changes to the
lowest band, i.e., SW1 (90-meter) band.
The band indicator on the LCD moves appropriately each time the
band is changed.
When the "DOWN" key is pressed while receiving a shortwave band, the
receiving band changes to the next adjacent lower band successively.
When the SW1 (90-meter) band is reached, however, the band changes
to the highest band, i.e., SW12 (11-meter) band. The band indicator
on the LCD moves appropriately each time the band is changed.
When the "UP" or "DOWN" key is kept depressed approximately for
more than 500 msec, the band changes up or down to the adjacent
band at an interval of approximately 250 msec until the lowest or the
highest band is reached at which the band changing ceases.
When the SW band is changed up and down, the receiver receives the
same channel number allocated for this receiver as the last channel of
the last band. When the band is changed from SW6 (31-meter) to SW5
(41-meter) and the receiving channel has been higher than the channel
104, however, the receiver receives the channel 104, i.e., the highest
channel of these lower shortwave band group of this receiver.
When the band is changed from SW12 (11-meter) to SW1 (90-meter)
band and the receiving channel has been higher than the channel 102,
the receiver receives the channel 102.
Clock Indication and Timer Setting
When the '"'CLOCK" key is pressed, the "CLOCK" indication goes on
on the LCD and the present time is displayed on the LCD at the same
time. When the ""CLOCK''-key depression is released, these "CLOCK"
and time displays disappear, and the displays go back to these ones
which had been displayed prior to the ""CLOCK"-key depression.
Clock-timer setting is made by turning the "TUNING/TIME ADJ"
knob with the ''CLOCK" key kept depressed. The timer counter stops
counting at the instance the time is set and the "'second"' resetting is
made.
Entries of other keys during the clock-time setting are prohibited.
When the time coincides with the alarm time during the clock time set-
ting, the set does not change its function.
Alarm-time Indication and
Alarm-time Setting
When the '"'ALARM" key is pressed, the ""ALARM" indication goes on
on the LCD and the present time is displayed on the LCD at the same
time. When the ""ALARM"-key depression is released, these "ALARM"
and time displays disappear, and the displays go back to these ones
which had been displayed prior to the ""ALARM"''-key depression.
b) Alarm-time setting is made by turning the "TURNING/TIME ADJ"
knob with the "ALARM" key kept depressed.
c) Entries of other keys during the alarm-time setting are prohibited.
d) When the time coincides with the clocktime during the alarm-time set-
ting, the set does not change its function.
STANDBY
'| ON-OFF of Standby Condition
By pressing this key, cyclic or alternate on-off state of the standby condi-
tion is made. When the set is in the standby condition, the LCD displays
the "STANDBY" on it.
