Key Description
(1) M1 to M6 and ME
(a) RADIO mode
These keys are used to carry out ‘preset memory’ write and read operations.
– Slow type (DIMRX ‘MEMORY TYPE’=0)
If any of M1 to M6 keys is turned off within a 1.5 seconds, the memory data that corresponds to that key will be
read. If it is pressed continuously for more than 1.5 second, the frequency currently displayed will be written to
the memory.
– ME key type (DIMRX ‘MEMORY TYPE’=1)
If the ME key is pressed, the P character (indicating the preset channel) will be flashing at a cycle of 2Hz. This
means that data can be written to the preset memory. If any key of M1 to M6 is pressed in this situation within
5 seconds, the frequency currently displayed will be written.
If any other key is pressed or the HOLD (active low) signal becomes active within the 5 seconds, the write status
will be released.
(b) TAPE mode
In the TAPE mode, keys M4 to M6 can be used as the TAPE keys.
Through the DIMRX selection, the following DOUBLE FUNCTION keys becomes available. Each key (M4 through
M6) has their own function. The DOUBLE FUNCTIONs marked by the ‘-’ are not supported.
(c) VF mode
During the TAPE and RADIO operation under the VF mode, keys M1 through M6 can be used for tuning.
(d) Clock update with the ME key (DIMRX ‘MEMORY TYPE’=1)
The clock update can be performed by pressing the HA and MA (or the M1 and M2 ) while holding down the ME
key.
This function is effective only when the HOLD (active low) becomes inactive (or at the POWER on).
(2) HA and M1
These keys are used to update the ‘HOUR’ value. However, note that they only allow the value to increase. If they are
pressed once, the value will be incremented by 1 (one hour). If they are pressed continuously for more than 500ms,
the value will increase at a speed of 4 (hours) per socond. These keys do not affect the minute and second data
display. If the ME key is used, these keys should be pressed synchronously with it. If it is not used, they should be
pressed synchronously with the DISPLAY key.
This function is effective only when the clock display is active.
In the TAPE mode, the HA key can be assigned to the APS or the MTL .
(3) MA and M2
These keys are used to update the ‘minute’ value. However, note that they only allow the value to increase. If they are
pressed once, the value will be incremented by 1. If they are pressed continuously for more than 500ms, the value can
be increased at a speed of 8 (minutes) per second. In this case, the ‘second’ value is reset to 0. There will be no carry
from the minute data. If the ME key is used, they should be pressed synchronously with it. If the ME key is not
used, they should be used together with the DISPLAY key. This function is effective only when the clock display is
active.
In the TAPE mode, the MA key can be assigned to the NR .
Keys HA and MA can have the following functions through the DIMRX ‘FKEY0, 1’ manipulation.
