GENERAL
INFORMATION
Your TS-700SP has been factory aligned and tested to
specifications
before
shipment.
Under
normal
cir-
cumstances the transceiver will operate in accordance with
these
operating
instructions
when
properly
adjusted.
Attempting service or alignment without factory. Authoriza-
tion can void the transceiver's warranty.
XTAL
Frequency
Adjustment
When
fixed
channel
crystals
are
installed
in the
transceiver, adjust their frequencies as outlined below.
(the
relationship between the markings on the FIX CH knob and
the crystal oscillator sockets are shown in Fig. 16):
1, Pull up the two latches and open the top lid. (see Fig.
15)
2. Adjust the trimmers (TC1
~
TC11) corresponding to
the newly installed crystals to produce the desired os-
cillator frequencies
(refer to Paragraph
4-14.
"Fixed
Channel
Operation').

Calibration
1. Connect the power cord to a wall outlet.
2. Turn the POWER
switch ''on", keeping the STANDBY
switch at REC.
3. Pull on the 7-DIGIT (FM) DISPLAY
switch inside the
TS-700SP
Note:
After calibration, press the switch in.
4. Set the FIX. CH switch to the channel to be calibrated.
5. Set the MODE switch to the mode for which the XTAL
was cut.
6. While observing the digital display, adjust the trimmer
corresponding
to the installed crystal, until the digital
display reads the specified frequency (see Fig. 16).
Note:
Use an insulated tuning tool:
Trimmers
are not at
ground potential.
