8)'
Press each of the three frequency-up keys
(23) -
Pressing a key
increments the digit above it by 1,
and holding the key causes the
digit to advance continuously with a slight delay.
Check individual
key operation.
Ihe frequency range can be automatically incremented
up to 159.9 kHz.
9}
Press each of the three frequency—down keys
1 ( 24) .
In contrast with
the frequency—up keys, the digit is decreased,
thereby causing the
frequency range to be decremented automatically down to 5.0 Hz.
10)
Turn the MODIFY control
(28)- clockwise to increase the frequency
and counterclockwise to decrease the frequency step by step.
One
rotation of this knob represents 50 detents.
Since it can be turned
endlessly,
the frequency can be varied through all ranges.
Carry
up, borrow down, and automatic range switching can be performed.
The digit to be changed is selected by the MODIFY digit select
switch
(27) .
_________ NOTE-----
As described in 8),
9)
and 10), the frequency can be
controlled by either six up/down keys (2^3) , (24)
or the
MODIFY control in the normal mode.
The MODIFY rotary switch is named so because it is used
to modify the values when the up/down keys have been
disabled after recall in the preset mode.
11)
The frequency range-up key
(25)
and frequency range-down key
(2^6)
switch the frequency range.
The frequency is multiplied or
divided by 10 each time a key is pressed, thus changing the
frequency rapidly by a large amount.
In the lowest range
(5 to
159.9 Hz)
the range-up/down key may have to be pressed twice in
some cases since the ratio of this range exceeds 10.
Example:
12.0 Hz,
120.0 Hz, 1.200 kHz,
12.00 kHz,
120.0 kHz.
(These keys can be called the decade—up/down keys.)
