Key Functions
1. CH1/TIMER-ON , CH2/TIMER-OFF , CH3 to CH8 , ME
During frequency display
These keys are used to write to and read from preset memory.
Write
When the ME key is pressed the figure
flashes in the frequency display and the write state is entered for 5 seconds.
If one of the CH1 to CH8 keys is pressed again during that 5 second interval, the frequency is stored in that channel
memory. If the FM band is selected, and the ME key is pressed during the 5-second write state interval, the figure
flashes in the display, and the frequency can be stored in channel CH9 to CH16 by pressing one of the CH1 to CH8
keys. Pressing the ME key again clears the write state. If the AM band is selected, pressing the ME key while the
display is flashing clears the write state.
For the FM band, the MO/ST state is also stored with the frequency.
Pressing either the CH-UP/T-ON or the CH-DOWN/T-OFF key during the write enabled state clears the write state
and recalls the contents of the preset memory.
Read
When the FM band is selected, pressing one of the CH1 to CH8 keys once recalls the frequency and MO/ST state for
that channel, and pressing that key a second time recalls the frequency for the corresponding channel in channels 9
through 16.
When an AM band is selected, pressing one of the CH1 to CH8 keys once recalls the frequency for that channel.
During clock or timer adjustment display (The CH3 to CH8 keys function in the same manner as they do in
frequency display.)
When the ME key is pressed, the colon between the hour and minute displays flashes, and the system enters clock
adjustment mode. In this mode the T-UP key adjusts the minute setting and the T-DOWN key adjusts the hour setting.
T-UP key :
Pressing this key once increments the minute setting, and holding it down in excess of
500 ms increments the minute setting at 8 minutes per second.
During this operation the seconds setting is set to zero by the reset, and there is no carry
performed out of the minutes settings.
T-DOWN key:
Pressing this key once increments the hour setting, and holding it down in excess of
500 ms increments the hour setting at 4 minutes per second.
During this operation the seconds setting is not affected.
The colon between the hour and minute displays remains lit while either of the T-UP or T-DOWN key is pressed.
Return to normal operation: If no key is pressed for 5 seconds, clock adjustment mode is automatically cleared.
Pressing the ME key twice clears clock adjustment mode.
Pressing any other key clears clock adjustment mode and executes that key’s function.
Pressing the CH1/TIMER-ON key recalls the on timer setting, lights the T-ON indicator, and flashes the colon
between the hour and minute displays. In this mode, the T-UP key adjusts the minute setting and the T-DOWN key
adjusts the hour setting. (500 ms lit, 500 ms off)
