When there is no reception
If the radio was not able to receive any of the frequencies for the
time zone stored in the ROM, scanning stops with a beep when
the radio returns to the frequency where it started scanning.
Short wave reception may be difficult at times due to various
factors, such as sunspot activity and atmospheric conditions.
Furthermore, the major broadcast stations whose data are stored
in the ROM may change the broadcast time and/or frequencies
at the change of season, etc. In such cases, the radio may not be
able to receive the frequencies stored in the SW STATION CALL
ROM.
Updating the SW STATION CALL ROM
To conform with possible changes in frequencies, the SW
STATION CALL ROM is designed to be replaceable by the user
to an updated version of the ROM. The newest SW STATION
CALL ROM is sold by F Corporation. The ROM is to be updated
in around October every year. We recommend the ROM to be
replaced at least once in 2 to 3 years.
To purchase the newest ROM, refer to "Purchasing the latest SW
STATION CALL ROM" and contact F Corporation.
To exchange the ROM, see "Exchanging the SW STATION CALL
ROM", page 46.
Notes
• Many of the worldwide broadcast programs of the major broadcast
stations stored in the ROM are broadcast only at certain times of the
day. If the station is not broadcasting on the scanned frequency at the
time, the radio will not receive any broadcast or receive broadcast by
some other station, such as a local station, broadcasting on the same
frequency.
• If the frequency is changed by manual tuning, etc., when "SW
STATION CALL" indication is lit in the display, the radio will exit SW
STATION CALL and the indication will disappear.
• If there is no frequency for the station corresponding to the time zone
stored in the ROM, a beep sounds, "MEMORY" "EMPTY" appears in
the display, and the radio returns to the previous condition.
• If you press a station button without the ROM in the ROM
compartment of the radio, a beep sounds, "NO" "ROM" appears in the
display, and the radio returns to the previous condition. If the ROM is
displaced when "SW STATION CALL" indication is lit in the display,
a beep sounds, "NO" "ROM" appears in the display, and the radio
changes to manual tuning.
• If "NO" "ROM" is displayed with the SW STATION CALL ROM
inserted in the ROM compartment, the contact surface of the ROM
may be dirty. See "Cleaning the SW STATION CALL ROM contact
surface", page 46, and clean the contact surface with a cotton swab.
Do not clean the contact springs of the main unit, as they may deform
and cause a malfunction.
